Before implementing Single Root I/O Virtualization (SR-IOV) in your customer’s environment, which requirements must you fulfill? Choose three.

A: Ensure that the physical host has vSphere 5.5 installed Ensure that the host has an Intel processor Check the vSphere documentation to ensure the host configuration is supported Ensure that the host has an AMD processor Q: You are discussing the use of virtual machine templates for deployment with a customer. The customer is unsure of the differences between the templates and clones and does not understand why they should create templates at all. Which of the following examples would you use to demonstrate the difference between them? Choose two. A: Templates can’t be edited or powered on and so are ideally suited for consistently deploying large numbers of identically configured virtual machines Clones are exact copies of virtual machines at the time of cloning and so are best suited for quickly creating test and development copies of virtual machines. Clones include all snapshots that are active on a virtual machine so you must use clones if you want to make a copy of virtual machine snapshots Templates are extremely portable and can be used to export and transport fully configured virtual machines outside of your vSphere environment

Q: Your customer has an application solution that runs 4 virtual machines. They need to replicate this solution repeatedly over a period of time into a number of separate production instances. What deployment method would you recommend to your customer as being the most suitable for their needs? Choose one.

A: Power off the virtual machines and convert them to 4 templates. These 4 templates should be used to deploy 4 new virtual machines when required. When a new instance of the solution is required the 4 new virtual machines should be cloned from the original application solution virtual machines. Convert the 4 virtual machines to a single template. When a new instance of the application solution is required deploy the virtual machines using this template. Make multiple clones of the running virtual machines and copy them to secondary storage until they are required. Migrate the clones to production as required. Q: You have proposed a solution for a customer to extend an existing vSphere cluster that supports HA and DRS where all virtual machines run Windows 2008. The existing cluster uses Intel Xeon X5650 CPUs, and you have specified the same CPUs for the new hosts in your proposal. The customer has challenged your design, indicating that they believe there are more cost effective hosts available that use AMD CPUs. What major impact would choosing the AMD based hosts have? Choose one.

A: vMotion, and fully automated DRS, would no longer work between all hosts HA could not be used as VMs might crash if restarted on the new hosts DRS could only continue to be used if it is reconfigured to use Cold Migration The customer would have to create an EVC DRS cluster to support both host types Q: Your customer is using snapshots in their environment as they want to return the virtual machine and virtual disks to the state that they were in when they took the snapshot. However, when they revert to a previous snapshot the virtual machine is powered off. What could be the possible cause? Choose one. A: Your customer did not select the option to snapshot the virtual machine memory Your customer did not select the option to quiesce the guest memory Virtual machine are always restored in a powered off state from a snapshot Your customer did not have VMware tools installed in the guest operating system Q: You are trying to hot-add an IDE disk to a running virtual machine; however the option is greyed out. What could be the possible cause for this? Choose one. A: The virtual machine’s guest operating system does not support hot adding hardware It is not possible to hot-add IDE disks to a running virtual machine The virtual machine is does not have VMware Tools installed The vSphere host does not have any unassigned physical IDE disks Q: You customer has asked you to present your design for a vSphere cluster to support their production environment. When they examine the design, they notice that you have specified a total amount of physical RAM lower than the total amount of RAM they have specified for the virtual machines that the cluster will be required to support. They are concerned that the solution will be unable to support the virtual machines with the configuration they require. Which of the following vSphere features should you discuss with the customer in order to explain how vSphere can support the memory over-commitment that you have integrated into your design? Choose three. A: Transparent Page Sharing Page compression Memory Compression Memory Thrashing Ballooning Q: Your customer’s existing backup solution can backup virtual machines but it can only perform full backups. They are interested in using the vSphere Data Protection appliance to replace their existing VM backup solution, but would like to know more information regarding its benefits. Which of the following are benefits of using VDP? Choose two. A:

VDP uses vSphere replication to recover virtual machines and files from another vCenter Server VDP uses changed block tracking to minimize the amount of data to process for each backup VDP does not require additional management software VDP can only restore files for powered on virtual machines Q: Your customer has a vSphere 5.5 environment where all hosts are correctly configured with vSphere Standard Edition. They have a virtual machine running from the local storage of one of the hosts that they want to live migrate to shared storage using enhanced vMotion. When they select the migrate option in the vSphere Client they notice that they are not presented with an option that will allow them to vMotion the machine, but they can use Storage vMotion. Why are they unable to use enhanced vMotion to migrate the VM and its storage at the same time? Choose one. A: Enhanced vMotion migration requires an Enterprise License Enhanced vMotion migration requires an Enterprise Plus License Enhanced vMotion is only available as an option in the vSphere Web client They have not configured the cluster for Enhanced VMotion Compatibility Q: You are engaged in the planning stage prior to a large scale deployment of virtual machines which will have various hardware configurations. Which of the following are important steps in order to effectively plan the environment? Choose two. A: Create a vSwitch port group for the virtual machines Check the configuration maximums document Ensure you have adequate licensing in place Configure VMware vSphere Host Profiles Q: You are designing a remote desktop solution for your customer, they have specified that each virtual machine must have 4 vCPU’s, 128GB of RAM and be able to support graphic-intensive workloads. Which of the following must be features of your solution in order to achieve your customers design goals? Choose two. A: Hardware-Based vGPU support VMware vSphere 5.1 VMware Horizon View 128GB of RAM in each vSphere Host Q: You have a customer who has been testing a vSphere 5.5 solution for application development that will require virtual machines with up to 64vCPUs. They have successfully tested smaller virtual machines but they cannot power on a virtual machine which has been created with 64 vCPU’s. The virtual machine is correctly registered in vCenter Server. What is the most likely cause of the issue? Choose one. A: The customer is using a free version of VMware vSphere Hypervisor The host is not licensed for the correct amount of physical cores and memory

The customer has not disabled transparent page sharing on their ESXi hosts The host is not licensed for the correct amount of physical cores Q: You are engaged in the deployment phase of vSphere Data Protection Advanced (VDPA). However, you find that your colleague has not signed off on all of the installation pre-requisites. Which of the following are required in order to successfully deploy and manage the VDPA appliance? Choose three. A: vCenter Server vSphere Desktop Client vSphere Web Client vCenter Operations Manager Single Sign-On

Q: When designing for vMotion which of the following should you consider? Choose three.

A: All hosts must use CPUs from the same vendor and family All hosts must have Gigabit Ethernet network connectivity The solution should include Shared Storage for virtual machines You must specify that VMs run compatible guest operating systems You must specify that vSphere hosts are licensed with an Enterprise license Q: Your customer requires a solution that will allow them to quickly move running virtual machines between all their hosts using vMotion. Their current setup has 8 identical hosts running the free vSphere Hypervisor. Which of the following will they need to do, at a minimum, in order to gain this functionality? Choose two. A: Upgrade from the free vSphere license to a vSphere Standard license Upgrade from the free vSphere license to a vSphere Enterprise license Deploy shared storage for the virtual machine storage Copy each virtual machine to an NFS share

Q: Your customer reports that an application in their virtual machine appears to be underperforming and performance counters show that the application is utilizing 95% of CPU resources. The customer wants to be able to hot-add additional CPUs to the virtual machine to resolve this without shutting the machine down, but cannot. Which of the following are possible reasons? Choose two.

A: The guest operating system must support hot add of CPU The virtual machine must be shutdown in order to add CPU VMware tools is not installed in the virtual machine An Enterprise Plus license is required to hot add CPU Q: In order to ensure that you can successfully replicate between one environment and another, you must verify that your customer’s virtual infrastructure respects certain limits before you start replication. Which of the following apply? Choose two. A: You must pair a ‘master’ vSphere Replication Appliance with vCenter Server You must be able to allocate 4GB of RAM and 4 vCPUs for each appliance You should ensure compatibility with all vSphere features in use Deploying more than one vSphere Replication appliance is prohibited Q: Your customer reports that several virtual machines are performing slower than expected. When you investigate the issue, you find that each virtual machine has multiple active snapshots. You also find that the amount of available storage space on the datastore where the virtual machines are located is very low. What recommendations would you give to your customer with regards to using snapshots? Choose two. A: Snapshots should not be used for a long period of time on production systems Snapshots can only be supported in conjunction with full virtual machine backups Use Storage vMotion to convert the virtual machine disk files to thin provisioned disks Check that the vSphere datastore alarm is set to a value above 30% and that it is working Q: Your customer is investigating DR solutions for their vSphere production environment where they use DRS, HA and vMotion extensively. They have found that the cost estimates for storage solutions that can support hardware replication from their existing site is prohibitive. You are considering proposing a vSphere Replication as a solution for them but you must ensure that their environment can support it. Which of the following items must you check in order to be confident that vSphere Replication will be suitable? Choose two. A: Confirm the version of ESXi Server onsite Confirm that they are using iSCSI storage only Confirm that they have Enterprise Plus licenses Confirm that a 15 minute RPO meets their needs


Your customer is considering virtual machine backup solutions for their environment. They require a solution that will allow them to dynamically expand backup data capacity and backup 150 Virtual Machines. Which solution would be the most appropriate for your customer? Choose one.

A: vSphere Data Protection Virtual machine Snapshots vSphere Data Protection Advanced Virtual machine Clones Q: During the design phase of a solution, your customer has specified that two virtual machines which are part of an application cluster must be configured with virtual network interface cards that will deliver the best performance for network communication between them. The customer has specified that the virtual machines can run on the same vSphere ESXi host, but for network architectural reasons cannot be connected to the same virtual switch. Which adapter would you recommend? Choose one. A: Flexible VMXNET3 E1000 It does not matter as the virtual machines will be located on the same host.

Q: Which of the following is a major design goal of the vSphere CPU scheduler? Choose one.

A: Fairness Efficiency Throughput Isolation
