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 deprec ated 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 Now S-Controls are superseded by Visualforce now. 3.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 Vis ualforce. Each visualforce tag always begins with apex namespace. All the design part can be determined by using Visualforce Markup Language and the business log ic 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->Pa ges and create new Visulaforce page. b. Setup -> My Personal Information -> Pers onal Information -> Edit check the checkbox development mode. When we run the pa ge 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 cl ass associated with it, there itself. c. Using EclipseIDEwe can create the Visul aforce page and write the code. 6. What are Apex Governor Limits? Ans: Governor Limits are runtime limits enforced by the Apex runtime engine. Bec ause Apex runs in a shared, multitenant environment, the Apex runtime engine str ictly enforces a number of limits to ensure that code does not monopolize shared resources. Types of limits that Apex enforces are resources like memory, databa se resources, number of script statements to avoid infinite loops, and number of records being processed. If code exceeds a limit, the associated governor issue s 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 i n separate environments for a variety of purposes, such as testing and training, without compromising the data and applications in Salesforce production organiz ation. These copies are called sandboxes and are nearly identical to Salesforce production organization Sandboxes are completely isolated from Salesforce production organization, so op erations we perform in sandboxes do not affect Salesforce production organizatio n, and vice versa. The sandbox types are: Configuration Only: Configuration-only sandboxes copy all of production organiza tion's reports, dashboards, price books, products, apps, and customizations unde r Your Name ->Setup, but exclude all of organization's standard and custom objec t 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 refres h 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-o nly sandboxes, developer sandboxes copy all application and configuration inform ation 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 orga nization and all its data, including standard and custom object records, documen ts, 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 fea ture. We can generate backup files manually once every six days or schedule the m to generate automatically at weekly or monthly intervals. The backup file wi ll 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 fe ature, contact salesforce.com support to have the Data Export Service activated. The following path will tells us how to schedule the export Click Setup -> Dat a 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 execu tion 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 no t. If it contains a value, this function returns FALSE ISBLANK (expression): The expression allows both number and text fields. Both number and text fields ISN ULL(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 Approval Processes Are triggered upon Save Are triggered only whe n a user clicks Submit for Approval button Consist of one set of criteria and acti ons Consist of multiple steps Have an entry criteria, step criteria and step ac tions Have Initial submission actions, rejection and approval actions and actio ns for each step Can be modified or deleted Some attributes can t be modified , pr ocesses 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. Text b. HTML with Letter Head c. Custom HTML d. 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 fie ld 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 obje ct. 15. What are the Record Types? Ans: Record types used to display different picklistvalues and page layouts to d ifferent 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 a lso 17. How to make the Record type as a default? Ans: By using the Profiles. Go to the particular profile and by using Record Typ e 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 fro m 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. Master Detail b. Many to Many c. Lookup d. 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 th e user object. It allows creating a Manager Field on the user object to relate a nother 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 identifica tion and create two Master - Detail relationships for this object. And this Obje ct is called as Junction object. 22. What is JUNCTION object? Ans:A Junction object is a Custom object with two Master-Detail relationships. U sing 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 tr y to delete the records in C what happens to the child? Ans: Childs will also delete as per the properties of Master- Detail relationshi p. 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. Old record loaded from database 2. New record values overwrite old values 3. System Validation Rules 4. All Apex before triggers 5. Custom Validation Rules 6 . Record saved to database (but not committed) 7. All Apex after triggers (EE / UE only) 8. Assignment rules 9. Auto-response rules 10. Workflow rules 11. Escalat ion rules 12. Parent Rollup Summary Formula value updated (if present) 13. Datab ase 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. A s a best practice create one trigger per object and use comment blocks to separa te 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 de activate 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 Acco unt, Lead etc and in criteria select the users name and delete all records of th at 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 opportun ity, 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 i nsert 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. Fo r 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 Co ntact 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 f ields 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 get Name() { 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 Standa rd 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 functionali ty 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 co ntroller. 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 a lready exists ? If we deletes the Parent record, then the Childs will not be del eted ? 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, t hen the Childs will be deleted ? Mandatory ? The OWD s can be inherited from the P arent object if we have lookup relationship between them ? Read Only field 39. What is Master Detail relationship and look up relationship in Salesforce? W hat 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 Master-Detail Relationship We can create 25 lookup relations hips for both standard and custom objects We can create 2 Master-Detail relatio nships for custom objects Lookup Relationship can be created if records already exists Master-Detail relationship cannot be created if records already exists If we deletes the parent record, then Childs will not be deleted If we delete the parent record, then childs will be deleted automatically Optional Mandatory The Ownership and the sharing of a child record are not determined by the parent The Ownership and the sharing of a detail record are determined by the Master Interview Questions record record Editable field 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 crea te 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 validatio n rules. 44. What is the difference between database.insert and insert? Ans: insert is the DML statement which is same as databse.insert. However, datab ase.insert gives more flexibility like rollback, default assignment rules etc. w e can achieve the database.insert behavior in insert by using the method setOpti ons(Database.DMLOptions) Important Difference: If we use the DML statement (inse rt), then in bulk operation if error occurs, the execution will stop and Apex co de throws an error which can be handled in try catch block. If DML database meth ods (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 acces s the record. For example: if there is custom setting of name ISO_Country, ISO_C ountry__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 us e: Interview Questions MapmapCodes = ISO_Country__c.getAll(); // display the ISO code for India System.debug( ISO Code: +mapCodes.get( INDIA ).ISO_Code__c); //Alternat ively we can return the map as a list: ListlistCodes = ISO_Country__c.ge tAll().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 wi ll happen if we delete one master record? 47. What is Difference in render, rerender and renderas attributes of visualforc e? Ans: render It works like display property of CSS. Used to show or hide element. r erender: 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,do c 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 mus t 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 Sch edule , when user clicks on that button, new interface opens to schedule the class es 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 ar e also found in profiles, but permission sets extend users functional access with out changing their profiles. A profile will have many users. If we change the permissions at profile level, t hen all the users associated with that profile will change. If we want extend th e permissions for only for particular users, and then we have to create permissi
on 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 t o 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 fie ld for each account. They can then refer to that ID field, rather than the sales force.com id. Note: 1. if we have an external ID field, the field becomes searchable in the si debar 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 i n multiple records for the unique field. So if I create a 5 character text field and make it unique, and I create a recor d 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 th e 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, c all 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 behavio rs, 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 spec ify what happens when a user interacts with the components specifiedin associate d 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, a nd 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 resul ts 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 behavior s, but we must also reimplementanyfunctionality that was already provided in a s tandard controller. Controller Extensions:A controller extension is a class written in Apex that add s to or overrides behavior in a standard or custom controller.Extensions allow u s to leverage the functionality of another controller while adding our own custo m logic. 54. How many Controllers can be used on single VF page? Ans: Only one controller can be used salesforce. Other than them, Controller ext ension can be used. There may be more than one Controller extention.
if the extension classes ExtOne and ExtTwo, both have the method getFoo() then t he 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 ex tend. 55. Explain System.runAs()? Ans: Generally, all Apex code runs in system mode, and the permissions and reco rd sharing of the current user are not taken into account. The system method, Sy stem.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 Accou nt(); 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 th e visual force controller. 57. What is the Custom Settings? Ans: custom setting that provides a reusable set of static data that can be acc essed 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 a n organization, profile, or specific user. All custom settings data, which enabl es efficient access without the cost of repeated queries to the database. This d ata can then be used by formula fields, validation rules, Apex, and the Web serv ices API. 58. What are the Types of Custom Settings? Ans: There are two types of Custom Settings a. List Custom Settings b. Hier arc hy Custom Settings 59. Difference between SOSL and SOQL in Salesforce? Ans: SOQL SOSL Stands for "Salesforce object search language" Stands for "Salesforce object query language" SOQL retrieves the records from the database using SELECT k eyword SOSL retrieves the records from the database using FIND keyword Works on m ultiple objects at a same time. Need to write different SOQL for different objec t. Cannot used in Triggers. Can only be used in Apex class and anonymous block. 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, regardles s of sharing settings. Modify All : Give All (Read, Create, Add, Delete) permiss ion to selected Object. 62. If i want record level access then what should i use from Salesforce securit y 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 secur ity model? Ans: Profile 64. In OWD (Organization wide Defaults), can i change the setting Grant Access Us ing Hierarchies for Standard Objects? Ans: We cannot change it for Standard Objects However for Custom Objects it s poss ible. 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 upd ate 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 upda te 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 set ting 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 opt ion. It is possible that the functionality of page does not required any Standard obj ect or may require more than one standard object, then in that case Custom contr oller is required. Interview Questions 70. In class declaration if we don t write keyword with sharing then it runs in syst em mode then why keyword without sharing is introduced in apex? Ans: Lets take example, there is classA declared using with sharing and it calls c lassB method. classB is not declared with any keyword then by default with sharin g 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 a ccess 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 prof ile. 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 De tails: formatting, grouping and subtotals are lost. 76. Which permission is required to set the running user other than you in dashb oard? 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.

Ans: Dashboard which is running under current logged in user permission are know n 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 man ually. 81. What is analytic Snapshot in salesforce? Ans: Analytic snapshot capture and store the data at pre decided intervals. It c
aptures data from report and saves in custom object as per schedule. It only sup ports 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 fie ld. 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(fieldNa me) instead. ? We can t use COUNT() with a GROUP BY clause. Use COUNT(fieldName) i nstead. COUNT(fieldName): ? We can use COUNT(fieldName) with an ORDER BY clause. ? We can use COUNT(fieldN ame) 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 Hav ing 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 COUNT(Id) > 1 AN D Name like '%ABC%' 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 Load er? Ans: Use the setting Insert Null Values in the Data Loader settings. 86. What is the Customer Portal and Partner Portal?

Partner Portal:Partner relationship management allows companies to maximize th e return on their channel investments and increase revenues by managing, trackin g, and forecasting business alongside their direct sales business. It also helps partners sell more effectively, close more business, and achieve greater profit s. This Partner Portal determines partners with Salesforce data can help sell mo re without spending more. A partner portal allows partner users to log in to Sal esforce through a separate website than non-partner users. Partner users can onl y 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. Bec ause Apex runs in a shared, multitenant environment, the Apex runtime engine str ictly enforces a number of limits to ensure that code does not monopolize shared resources. Types of limits that Apex enforces are resources like memory, databa se resources, number of script statements to avoid infinite loops, and number of records being processed. If code exceeds a limit, the associated governor issue s a runtime exception. Total number of SOQL queries issued 200 Total number of records retrieved by SOQ L queries 50000 Total number of records retrieved by SOQL queries 20 Interview Questions Total number of records retrieved by a single SOSL query 200 Total number of DML statements issued 150 88. What are the annotations in the Apex? Ans: An Apex annotation modifies the way a method or class is used, similar to a nnotations in Java. ? @Deprecated ? @Future ? @IsTest ? @ReadOnly ? @RemoteActio n 89. What is @isTest annotation?

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 colle ctions. ? 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 conta in 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, sOb ject, 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 Ap ex 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 shari ng 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 acc esses records. Profiles Control a user s permissions to perform different function s in Salesforce. A profile can have many users, but a user can have only one p rofile. 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 thin g 97. What are the Assignment Rules? Ans: Assignment Rules are used to automate organization slead generation and suppo rt processes. Lead Assignment Rules specify how leads are assignedto users or queu es 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 refere nce fieldsfrom objects that are up to ten relationships We can able to insert re lated 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.
