Interview+Questions_Level+2+-+Final.pdf

Interview Questions 1. What is Apex? Ans: It is the technology of salesforce.com which is similar to Java programming with object oriented concepts and to write our own custom logic. 2. What is S-Control? Ans: S-Controls are completely based on Javascript. These S- Controls are deprecated in 2007 because it is not supporting Apex Language properly. Now S-Controls are superseded by Visualforce now. 3. What is a Visualforce Page? Ans: Visualforce is the new markup language from salesforce, by using which, we can render the standard styles of salesforce. We can still use HTML here in Visualforce. Each visualforce tag always begins with “apex” namespace. All the design part can be determined by using Visualforce Markup Language and the business logic can be written in custom controllers associated with the Page. 4. Will Visual force still supports the merge fields usage like S-control ? Ans: Yes. Just like S-Controls, Visualforce Pages support embedded merge fields, like the {!$User.FirstName} {!Account.Name}

5. Where to write Visualforce code? Ans: We can write the code basically in 3 ways. a. setup->App Setup->Develop->Pages and create new Visulaforce page. b. Setup -> My Personal Information -> Personal Information -> Edit check the checkbox development mode. When we run the page like this, https://ap1.salesforce.com/apex/MyTestPage. we will find the Page editor at the bottom of the page. we can write page as well as the controller class associated with it, there itself. c. Using EclipseIDEwe can create the Visulaforce page and write the code. 6. What are Apex Governor Limits? Ans: Governor Limits are runtime limits enforced by the Apex runtime engine. Because Apex runs in a shared, multitenant environment, the Apex runtime engine strictly enforces a number of limits to ensure that code does not monopolize shared resources. Types of limits that Apex enforces are resources like memory, database resources, number of script statements to avoid infinite loops, and number of records being processed. If code exceeds a limit, the associated governor issues a runtime exception.

Interview Questions 7. What are the types of sandboxes and what is the difference? Ans: Salesforce gives us the ability to create multiple copies of organization in separate environments for a variety of purposes, such as testing and training, without compromising the data and applications in Salesforce production organization. These copies are called sandboxes and are nearly identical to Salesforce production organization Sandboxes are completely isolated from Salesforce production organization, so operations we perform in sandboxes do not affect Salesforce production organization, and vice versa. The sandbox types are: Configuration Only: Configuration-only sandboxes copy all of production organization's reports, dashboards, price books, products, apps, and customizations under Your Name ->Setup, but exclude all of organization's standard and custom object records, documents, and attachments. Creating a configuration-only sandbox can decrease the time it takes to create or refresh a sandbox from several hours to just a few minutes, but it can only include up to 500 MB of data. We can refresh a configuration-only sandbox once per day. Developer Sandbox: Developer sandboxes are special configuration-only sandboxes intended for coding and testing by a single developer. Just like configuration-only sandboxes, developer sandboxes copy all application and configuration information to the sandbox. Developer sandboxes are limited to 10 MB of test or sample data, which is enough for many development and testing tasks. We can refresh a developer sandbox once per day. Full: Full sandboxes copy entire production organization and all its data, including standard and custom object records, documents, and attachments. 8. How to schedule export or take the backup of salesforce? Ans: Salesforce allows us to obtain a copy of all data using the data export feature. We can generate backup files manually once every six days or schedule them to generate automatically at weekly or monthly intervals. The backup file will come to us in the form a zip file that contains all of organization’s data in a set of CSV (comma-separated values) files. If we do not see the data export feature, contact salesforce.com support to have the Data Export Service activated.

The following path will tells us how to schedule the export Click Setup -> Data Management -> Data Export -> Schedule Export Note: 1. we have 48 hours from the time we are notified the backup is available to download the backup file. 2. The email notification for backups goes to the email address in Salesforce of the person logged in who schedules the backup

Interview Questions 9. Do governor limits apply to sandbox instances? Ans: Governor Limits do apply to all Salesforce instances (trial, developer, and production or sandbox environments). However code coverage and successful execution of test classes is only enforced when deploying to a production environment. 10. What is difference in ISNULL and ISBLANK? Ans: Both Determines if an expression has a value and returns TRUE if it does not. If it contains a value, this function returns FALSE ISBLANK (expression): The expression allows both number and text fields. Both number and text fields ISNULL(expression): Here the expression allows only number fields. Only number fields

11. What is the difference between the Workflow and Approval Process? Ans: Workflow Rules and Approval Processes can be used together Workflow Rules Are triggered upon Save Consist of one set of criteria and actions

Can be modified or deleted

Approval Processes Are triggered only when a user clicks “Submit for Approval” button Consist of multiple steps Have an entry criteria, step criteria and step actions Have Initial submission actions, rejection and approval actions and actions for each step Some attributes can’t be modified , processes must be deactivated before they can be deleted

12. When we can’t add Time dependent action in Workflow rule? Ans: We can’t add time-dependent actions to a rule if we choose “Every time a record is created or edited” evaluation rule criteria. 13. What are the types of email templates available in salesforce.com? Ans: There are four kinds of Email Templates a. b. c. d.

Text HTML with Letter Head Custom HTML Visualforce

14. What is Roll up summary field in Salesforce?

Interview Questions Ans: A read-only field that displays the sum, minimum, or maximum value of a field in a related list or the record count of all records listed in a related list. Thus, we can say that Roll up summary field can only be created on Master object. 15. What are the Record Types? Ans: Record types used to display different picklistvalues and page layouts to different users based on their profiles 16. Have you implemented Record Types in your project? Ans: Yes, we have created Record Types and we have done Page Layout Assignment also 17. How to make the Record type as a default? Ans: By using the Profiles. Go to the particular profile and by using Record Type Settings we can make the Record Type as a default 18. What will happen if the Account is deleted? Ans:If the Account is deleted then Contact, Opportunity will also be deleted from Salesforce which are related to that Account. 19. How many types of the relationship fields available in Salesforce? Ans: There are four types of relationships in salesforce a. b. c. d.

Master Detail Many to Many Lookup Hierarchical (It is available only on User Object)

20. What is Hierarchical Relationship? Does you ever used in your project?

Ans:It is the relationship available on User object which allows users to click a lookup icon and select another user from a pop-up list. This type of relationship is a special lookup relationship available only for the user object. It allows creating a Manager Field on the user object to relate another user. This relationship will acts as a Self relationships. 21. How to create many too many relationships between object?

Interview Questions Ans: Create one custom object, which should have autonumber as unique identification and create two Master - Detail relationships for this object. And this Object is called as Junction object. 22. What is JUNCTION object? Ans:A Junction object is a Custom object with two Master-Detail relationships. Using this custom junction object, we can model a “many-to-many” relationship between two objects.

23. Say If we created a junction object A with masters B and C? Suppose if we try to delete the records in C what happens to the child? Ans: Childs will also delete as per the properties of Master- Detail relationship. 24. In Which sequence Trigger and automation rules run in Salesforce.com Ans: The following is the order salesforce logic is applied to a record. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.

Old record loaded from database New record values overwrite old values System Validation Rules All Apex “before” triggers Custom Validation Rules Record saved to database (but not committed) All Apex “after” triggers (EE / UE only) Assignment rules Auto-response rules Workflow rules Escalation rules Parent Rollup Summary Formula value updated (if present) Database commit

25. If one object in Salesforce have 2 triggers which runs “before insert”. Is there any way to control the sequence of execution of these triggers? Ans: Salesforce.com has documented that trigger sequence cannot be predefined. As a best practice create one trigger per object and use comment blocks to separate different logic blocks. 26. How to delete the User from Salesforce? Ans: As per now, salesforce does not allow to delete any user, however we can deactivate the user. 27. How to delete the user’s data from Salesforce?

Interview Questions Ans: To delete the Users Data go to Your Name -> Setup -> Administration Setup -> Data Management -> Mass Delete Record, from there select the objects like Account, Lead etc and in criteria select the users name and delete all records of that user related to particular object. 28. How to restrict the user to see any record let’s say opportunity? Ans: Set up opportunity sharing to be private in Organization Wide Defaults. If both users are admins or have view all permissions at profile level on opportunity, then that overrides private sharing. 29. What is the difference between trigger.new and trigger.old in Apex? Ans: Trigger.new : Returns a list of the sObject records which we are going to insert into database Note that this sObject list is only available in insert and update triggers, and the records can only be modified in before triggers Trigger.old: Returns a list of the sObject records which already there in database Note that this sObject list is only available in update and delete triggers. 30. How to restrict any Trigger to fire only once? Ans: Triggers can fire twice, once before workflows and once after workflows. For this, add a static boolean variable to a class, and check its value within the affected triggers. 31. What is difference between WhoId and WhatId in the Data Model of Task? Ans: WhoID refers to people things. So that would be typically a Lead ID or a Contact ID WhatID refers to object type things. That would typically be an Account ID or an Opportunity ID 32. How to display error messages in the visualforcepage? Ans:In Apex use below code to create the error message for visualforce. Apexpages.addMessage(newApexPages.Message (ApexPages.Severity.ERROR, 'Required fields are missing. '));

In Visualforce page add below tag where we want to display the error message.

33. What is property in Apex? Explain with advantages.

Interview Questions Ans: Apex mainly consists of the syntax from the well-known programming language Java.As a practice of encapsulation in java we declare any variable as private and then create the setters and getters for that variable.

Private String name; Public void setName(String n) { Name=n; } Public String getName() { Return name; } However, the Apex introduced the new concept of property from language C# as shown below: publicString name {get; set;} It has another advantage in “number of lines of code” limit by salesforce which will drastically reduced. 34. What is the controller extension? Ans: Any apex class having a public constructor with Custom Controller or Standard Controller object as a single argument is known as controller extension. 35. Explain the need or importance of the controller extension? Ans: Controller extension is very useful and important concept introduced by the salesforce recently. It gives the power to programmer to extend the functionality of existing custom controller or standard controller. A Visualforce can have a single Custom controller or standard controller but many controller extensions. We can say that the custom extension is the supporter of custom or standard controller. 36. How to read the parameter value from the URL in Apex? Ans: Consider that the parameter name is “Test”. String Test = Apexpages.currentPage().getParameters().get(‘Test’); 37. What is lookup relationship?

Interview Questions Ans: It is the relationship which is used to connect the two objects Properties of Lookup Relationship:      

We can create upto 25 lookup Relationships Lookup can be create if records already exists If we deletes the Parent record, then the Childs will not be deleted Optional The OWD’s cannot be inherited from the Parent object if we have lookup relationship between them Editable field

38. What is Master detail Relationship?

Ans:It is the relationship which is used to connect the two objects Properties of Master-Detail Relationship:      

We can create upto2 Master-Detail Relationships Master- Detail Relationship cannot be created if records already exists If we deletes the Parent record, then the Childs will be deleted Mandatory The OWD’s can be inherited from the Parent object if we have lookup relationship between them Read Only field

39. What is Master Detail relationship and look up relationship in Salesforce? What is the difference? Ans: The Master-Detail and Look up relationships are used to connect two objects. They are one to many relationships. The differences are:

Lookup Relationship We can create 25 lookup relationships for both standard and custom objects Lookup Relationship can be created if records already exists If we deletes the parent record, then Childs will not be deleted Optional The Ownership and the sharing of a child record are not determined by the parent

Master-Detail Relationship We can create 2 Master-Detail relationships for custom objects Master-Detail relationship cannot be created if records already exists If we delete the parent record, then childs will be deleted automatically Mandatory The Ownership and the sharing of a detail record are determined by the Master

Interview Questions record Editable field

record Read Only field

40. Can we convert the lookup relationship to Master Detail relationship? Ans: We can convert the lookup relationship to master detail relationship if and only if all the existing record has valid lookup field. 41. In How much ways we can invoke the Apex class? Ans: 1. Visualforce page 2. Trigger 3. Web Services 4. Email Services 42. Can we create Master Detail relationship on existing records? Ans: No, first we have to create the lookup relationship then populate the value on all existing record and then we have to convert it. 43. How validation rules executed? Is it page layout / Visualforce dependent? Ans: The validation rules run at the data model level, so they are not affected by the UI. Any record that is saved in Salesforce will run through the validation rules. 44. What is the difference between database.insert and insert? Ans: insert is the DML statement which is same as databse.insert. However, database.insert gives more flexibility like rollback, default assignment rules etc. we can achieve the database.insert behavior in insert by using the method setOptions(Database.DMLOptions) Important Difference: If we use the DML statement (insert), then in bulk operation if error occurs, the execution will stop and Apex code throws an error which can be handled in try catch block. If DML database methods (Database. Insert) used, and then if error occurs the remaining records will be inserted / updated means partial DML operation will be done. 45. Other than SOQL and SOSL what is other way to get custom settings? Ans: Other than SOQL or SOSL, Custom settinghastheir own set of methods to access the record. For example: if there is custom setting of name ISO_Country, ISO_Country__c code = ISO_Country__c.getInstance(‘INDIA’); //To return a map of data sets defined for the custom object (all records in the custom object), //we would use:

Interview Questions MapmapCodes = ISO_Country__c.getAll(); // display the ISO code for India System.debug(‘ISO Code: ‘+mapCodes.get(‘INDIA’).ISO_Code__c); //Alternatively we can return the map as a list: ListlistCodes = ISO_Country__c.getAll().values(); 46. What happen if child have two master records and one is deleted? Ans: Child record will be deleted. This question will mainly ask when they asked how to achieve many to many relationships. Then we can answer by using Junction Object and two master detail relationships. Then next question would be what will happen if we delete one master record? 47. What is Difference in render, rerender and renderas attributes of visualforce? Ans: render – It works like “display” property of CSS. Used to show or hide element. rerender: If we want to refresh partial page in Visual force page we have to use rerender render as: By using this we can convert entire visual force into PDF,doc and excel. The syntax is Render as = “pdf” 48. What is Scheduler class in Apex? Ans: The Apex class which is programed to run at pre-defined interval. Class must implement schedulable interface and it contains method named execute(). There are two ways to invoke scheduler: 1. Using UI 2. Using System.schedule The classes which implements interface schedulable get the button texted with “Schedule”, when user clicks on that button, new interface opens to schedule the classes which implements that interface. To see what happened to scheduled job, go to “Monitoring | Scheduled jobs “ 49. Explain Permission sets? Ans:A permission set is a collection of settings and permissions that give users access to various functions. The settings and permissions in permission sets are also found in profiles, but permission sets extend users’ functional access without changing their profiles. A profile will have many users. If we change the permissions at profile level, then all the users associated with that profile will change. If we want extend the permissions for only for particular users, and then we have to create permission set and assign it to the user.

Interview Questions 50. What is the difference between External ID and Unique ID? Ans:External ID field:This is a field that usually references an ID from another (external) system. Ex: For instance, if the customer has an Oracle Financials system that they will be linking with salesforce.com, it may be easier for them to be able to refer to the Oracle ID of account records from within salesforce. So they would create an external ID in salesforce.com and they would load the Oracle ID into that field for each account. They can then refer to that ID field, rather than the salesforce.com id. Note: 1. if we have an external ID field, the field becomes searchable in the sidebar search. We also can use the upsert API call with the external ID to refer to records. 2. External Id available for Text, Number and Email field types. 3. External Id is used in upsert operations in the Data Loader  If external id is not matched then a new record is created.  If external id matched once then record will be updated.  If external id is matched multiple times then error occurs. Unique ID field: This is a setting for the field that will prevent us from using the same value in multiple records for the unique field. So if I create a 5 character text field and make it unique, and I create a record with the value “12345” i will not be able to create another record with that same value in the unique field. If i try to do so, I will get an error saying that the value is already in use. 51. How to get the picklist value in Apex class? Ans:Using Dynamic apex, we can achieve this. On object of field type picklist, call getDescribe(). Then call the getPicklistValues() method. Iterate over result and create a list and bind it to . 52. What is the Custom Controller? Custom Controller:A custom controller is a class written in Apex that implements all of a page's logic. If we use a custom controller, we can define new behaviors, but we must also reimplement anyfunctionality that was already provided in a standard controller. 53. What are the types of controller in visual force? Ans:There are basically two types of Controller in Visual force page. 1. Standard Controller and

Interview Questions 2. Custom Controller 3. Controller Extensions Controller definition:AVisualforce controller is a set of instructions that specify what happens when a user interacts with the components specifiedin associated Visualforce markup, such as when a user clicks a button or link. Controllers also provide access to the data thatshould be displayed in a page, and can modify component behavior. Standard Controller:A standard controller consists of the same functionality and logic that is used for a standard Salesforce page. For example, if you use the standard Accounts controller, clicking a Save button in a Visualforce page results in the same behavior as clicking Save on a standard Account edit page. Custom Controller:A custom controller is a class written in Apex that implements all of a page's logic. If we use a custom controller, we can define new navigation elements or behaviors, but we must also reimplementanyfunctionality that was already provided in a standard controller. Controller Extensions:A controller extension is a class written in Apex that adds to or overrides behavior in a standard or custom controller.Extensions allow us to leverage the functionality of another controller while adding our own custom logic. 54. How many Controllers can be used on single VF page? Ans: Only one controller can be used salesforce. Other than them, Controller extension can be used. There may be more than one Controller extention. if the extension classes ExtOne and ExtTwo, both have the method getFoo() then the method of ExtOne will be executed. A controller extension is any Apex class that contains a constructor that takes a single argument of type ApexPages.StandardController or CustomControllerName, where CustomControllerName is the name of a custom controller that we want to extend. 55. Explain System.runAs()? Ans: Generally, all Apex code runs in system mode, and the permissions and record sharing of the current user are not taken into account. The system method, System.runAs(), lets us to write test methods that change user contexts to either an existing user or a new user. All of that user’s record sharing is then applied.

Interview Questions System.runAs(u) { // The following code runs as user 'u' Account a= new Account(); a.Name=’Test Account’; insert a; }

56. Explain Test.setPage()? Ans:It is used to set the context to current page, normally used for testing the visual force controller. 57. What is the Custom Settings? Ans: custom setting that provides a reusable set of static data that can be accessed across your organization. There are two types of custom settings. Custom settings are similar to custom objects and enable application developers to create custom sets of data, as well as create and associate custom data for an organization, profile, or specific user. All custom settings data, which enables efficient access without the cost of repeated queries to the database. This data can then be used by formula fields, validation rules, Apex, and the Web services API. 58. What are the Types of Custom Settings? Ans: There are two types of Custom Settings a. List Custom Settings b. Hier archy Custom Settings 59. Difference between SOSL and SOQL in Salesforce? Ans: SOQL Stands for "Salesforce object search language" SOQL retrieves the records from the database using “SELECT” keyword Works on multiple objects at a same time. Cannot used in Triggers. Can only be used in Apex class and anonymous block.

SOSL Stands for "Salesforce object query language" SOSL retrieves the records from the database using “FIND” keyword Need to write different SOQL for different object. Can be used in Apex class and Triggers.

60. How to round the double to two decimal places in Apex? Ans: Decimal d = 100/3; Double ans = d.setScale(2) ; 61. In Profile settings, what is difference between “Modify All Data” and “Modify All”?

Interview Questions Ans:Modify All Data : Create, edit, and delete all organization data, regardless of sharing settings. Modify All : Give All (Read, Create, Add, Delete) permission to selected Object. 62. If i want record level access then what should i use from Salesforce security model? Ans: Manual Sharing (Enabling “Sharing Button” at the profile level) 63. If i want Object level accesses then what should i use from Salesforce security model? Ans: Profile 64. In OWD (Organization wide Defaults), can i change the setting “Grant Access Using

Hierarchies” for Standard Objects? Ans: We cannot change it for Standard Objects However for Custom Objects it’s possible. 65. What is Mandatory while creating User, Role or Profile? Ans: It’s Profile. 66. In case of Master-Detail relationship, on Update of master record can we update the field of

child record using workflow rule? Ans: Yes, We can do it using Cross Object field updates 67. In case of Master-Detail relationship, on Update of child record can we update the field of

Parent record using workflow rule? Ans: Yes, the Master fields are also available for “Evaluation Criteria”. 68. While setting OWD (Organization wide Defaults), can we change/modify the setting of child

record in case of Master-Detail relationship? Ans: No, Child record is controlled by the Parents setting. 69. What is the need of “Custom Controller” in Visualforce as everything can be done by the combination of Standard Controller + Extension class. Ans: Sharing setting is applied on standard object/extension by default; In case we don’t want to apply sharing setting in code then Custom controller is only option. It is possible that the functionality of page does not required any Standard object or may require more than one standard object, then in that case Custom controller is required.

Interview Questions 70. In class declaration if we don’t write keyword “with sharing” then it runs in system mode then why keyword “without sharing” is introduced in apex? Ans: Lets take example, there is classA declared using “with sharing” and it calls classB method. classB is not declared with any keyword then by default “with sharing” will be applied to that class because originating call is done through classA. To avoid this we have to explicitly define classB with keyword “without sharing”. 71. If user doesn’t have any right on particular record and have only read level access at object level. Can he change the record owner?

Ans : Yes. In profile, there is setting for “Transfer Record”. 72. How to hide the “App Setup” and “Administration Setup” Menu from user’s setup page? Ans: In Profile, remove access “View Setup and Configuration”. 73. While creating new profile for user, which existing profile should be copied? Ans: If the new user is not System administrator then copy from “Standard User” profile. 74. Who can run reports? Ans: Users with permission “Run Report” and access to report folder can only run the report. 75. What is Difference between “printable View” and “Export Details“button on report? Ans: Printable View: formatting, grouping and subtotals are persisted. Export Details: formatting, grouping and subtotals are lost. 76. Which permission is required to set the running user other than you in dashboard? Ans: “View All Data” in profile. 77. Who can access “drag and drop dashboard”? Ans: User with permission “manage dashboard”. 78. Which type of report can be used for dashboard components? Ans: Summary and Matrix report can be used to create dashboard components. 79. How many types of dashboard components are available? Ans: The following are the Data Components in the dashboards  Horizontal Bar Chart  Vertical Bar Chart

Interview Questions       

Line Chart Pie Chart Donut Chart Funnel Chart Gauge Chart Metric Table

Note: The Components of the dashboard that use the Grand Totals is Metric and Guage

80. Explain dynamic Dashboard. Ans: Dashboard which is running under current logged in user permission are known as “dynamic Dasboard”. At the most 3 dynamic dashboards can be built This type of dashboard cannot be scheduled for refresh. IT must be scheduled manually. 81. What is analytic Snapshot in salesforce? Ans: Analytic snapshot capture and store the data at pre decided intervals. It captures data from report and saves in custom object as per schedule. It only supports tabular and summary report as a source report. It does not support matrix report. The field type in target object must be same as source report object field. 82. Explain difference in COUNT() and COUNT(fieldname) in SOQL. Ans: COUNT()    

COUNT() must be the only element in the SELECT list. We can use COUNT() with a LIMIT clause. We can’t use COUNT() with an ORDER BY clause. Use COUNT(fieldName) instead. We can’t use COUNT() with a GROUP BY clause. Use COUNT(fieldName) instead.

COUNT(fieldName):  

We can use COUNT(fieldName) with an ORDER BY clause. We can use COUNT(fieldName) with a GROUP BY clause.

83. How to write the “Where” clause in SOQL when GroupBy is used? Ans:We cannot use the “Where” clause with GroupBy instead we will need to use the “Having Clause“.

Interview Questions Ex: Get all the opportunity where more than one record exists with same name and name contains “ABC”. SELECT COUNT(Id) , Name FROM Opportunity GROUP BY Name Having Name like '%ABC%'

COUNT(Id) > 1 AND

84. How many ways we can make the field required? Ans: We can make the field required in the three ways: a. While creating a field. b. Using Validation rules c. Using Page Layouts 85. How to give the blank value as the field value to the record using Data Loader? Ans: Use the setting “Insert Null Values” in the Data Loader settings. 86. What is the Customer Portal and Partner Portal? Ans: Customer Portal: A salesforce.com Customer portal similar to a Self – Service Portal in that it provides an online support channel for customers – allowing them to resolve their inquires without contacting a customer service representative. Partner Portal:Partner relationship management allows companies to maximize the return on their channel investments and increase revenues by managing, tracking, and forecasting business alongside their direct sales business. It also helps partners sell more effectively, close more business, and achieve greater profits. This Partner Portal determines partners with Salesforce data can help sell more without spending more. A partner portal allows partner users to log in to Salesforce through a separate website than non-partner users. Partner users can only see the data that we have made available to them. 87. What are the Governor Limits? Ans: Governor Limits are runtime limits enforced by the Apex runtime engine. Because Apex runs in a shared, multitenant environment, the Apex runtime engine strictly enforces a number of limits to ensure that code does not monopolize shared resources. Types of limits that Apex enforces are resources like memory, database resources, number of script statements to avoid infinite loops, and number of records being processed. If code exceeds a limit, the associated governor issues a runtime exception. Total number of SOQL queries issued Total number of records retrieved by SOQL queries Total number of records retrieved by SOQL queries

200 50000 20

Interview Questions Total number of records retrieved by a single SOSL query Total number of DML statements issued

200 150

88. What are the annotations in the Apex? Ans: An Apex annotation modifies the way a method or class is used, similar to annotations in Java.  @Deprecated  @Future  @IsTest  @ReadOnly  @RemoteAction 89. What is @isTest annotation? Ans:Use the isTest annotation to define classes or individual methods that only contain code used for testing your application. 90. How many controller extensions we can use in Visualforce Page? Ans: Any number of controller extensions 91. What are the Collections? Ans: Collection is a group of similar data types. There are three types of collections.  Lists  Maps  Sets 92. What is difference between the Sets and Maps? Ans:A set is an unordered collection of primitives or sObjects that do not contain any duplicate elements. A map is a collection of key-value pairs where each unique key maps to a single value. Keys can be any primitive data type, while values can be a primitive, sObject, collection type or an Apex object. 93. What are the data types we can give for the Key and Values in Maps? Ans: Keys – Primary Data Types Values – Primitive, sObject, Collection Type or an Apex object 94. What is the difference between the with sharing and without sharing keywords?

Interview Questions

Ans: Use the with sharing keywords when declaring a class to enforce the sharing rules that apply to the current user. Use the without sharing keywords when declaring a class to ensure that the sharing rules for the current user are not enforced 95. What is the difference between the Profile and Role? Ans:Profiles:A collection of settings and permissions that define how a user accesses records. Profiles Control a user’s permissions to perform different functions in Salesforce. A profile can have many users, but a user can have only one profile. Roles:Controls the level of visibility that users have to an organization's data 96. Can we create a user without assigning the profile? Ans: No, because while creating the user, selection of profile is mandatory thing 97. What are the Assignment Rules? Ans: Assignment Rules are used to automate organization’slead generation and support processes. Lead Assignment Rules—specify how leads are assignedto users or queues as they are created manually, captured from theweb, or imported via the lead import wizards. Case Assignment Rules—Determine how cases are assignedto users or put into queues as they are created manually, using Web-to-Case. 98. What is Cross Object Formula? Ans:Cross-object formulas can reference merge fieldsfrom a master (“parent”) object if an object is on thedetail side of a master-detail relationship. We can reference fieldsfrom objects that are up to ten relationships We can able to insert related Object data into a formula 99. How to hide a Tab for an User Ans: By profiles we can hide a tab for a user Use “Tab Hidden” setting for tab hide 100.

What is an External ID?

Interview Questions Ans: External IDs are used when we interacting with an external systems. It will act as unique record identifier. We can define 3 external ID fields per object. These are the data types of fields  Number  Text  Email 101. How to merge duplicates without going for Third Party tools? Ans:Click on the Tab and go to the Tools section, we can find the Merge option

Click on MergeAccounts

102.

How many ways we can do deployment?

Ans: There are three ways to do deployment i. By using Change Sets ii. By using Force.com IDE tool(Eclipse) iii. By using Force.com Migration toolkit 103. What is the best practice you are using while coding?
