NEW QUESTION 1
Which two types of iSCSI adapters require VMkernel networking configuration? (Choose two.)

• A. software
• B. in-guest
• C. independent hardware
• D. dependent hardware

Answer: AD

NEW QUESTION 2
An administrator notices that a host is evacuating all virtual machines and entering maintenance mode even though the host appears to be up and running.
Which new feature in vSphere 6.5 would cause this?

• A. Predictive DRS
• B. EVC Mode
• C. vCenter HA
• D. Proactive HA

Answer: D

Explanation: There are two vSphere Proactive HA Automation Levels:
Manual: vCenter Server will suggest only the migration recommendations for virtual machines. You need to manually migrate the virtual machines out from the degraded hosts.
Automated: Virtual Machines will be migrated to healthy hosts and degraded hosts will be entered into remediation action either quarantine or maintenance mode depending on the configured Proactive HA automation level

NEW QUESTION 3
What are two requirements in order to restore a Resource Pool Tree from a snapshot? (Choose two.)

• A. A restore can only be performed on the same cluster the snapshot was taken from.
• B. vSphere DRS must be turned on.
• C. vSphere DRS must be turned off.
• D. A restore can only be performed on a vSphere DRS cluster within the original vCenter Server.

Answer: AD

NEW QUESTION 4

Examine the LUN properties that are shown in the exhibit. Which action should be taken to utilize all active paths?

• A. Change PSP to Most Recently Used
• B. No action require
• C. All paths are already utilized.
• D. Change PSP to Fixed.
• E. Change PSP to Round Robin.

Answer: D

Explanation: The host uses an automatic path selection algorithm rotating through all active paths when connecting to
active-passive arrays, or through all available paths when connecting to active-active arrays. RR is the default for a number of arrays and can be used with both active-active and active-passive arrays to implement load balancing across paths for different LUNs.

NEW QUESTION 5
A vSphere administrator wants to reserve 0.5Gbps for virtual machines on each uplink on a distributed switch that has 10 uplinks.
What is the quota that should be reserved for the network resource pool?

• A. 5Gbps
• B. 10Gbps
• C. 100Gbps
• D. 0.5Gbps

Answer: A

Explanation: For example, if the virtual machine system traffic has 0.5 Gbps reserved on each 10 GbE uplink on a distributed switch that has 10 uplinks, then the total aggregated bandwidth available for VM reservation on this switch is 5 Gbps. Each network resource pool can reserve a quota of this 5 Gbps capacity.

NEW QUESTION 6
What is the result of a “Consolidate” action on a virtual machine?

• A. All snapshots on the virtual machines will be deleted.
• B. The virtual machine will be reverted to its last snapshot.
• C. Redundant delta disks will be combined and deleted.
• D. A new snapshot with memory state will be created.

Answer: C

NEW QUESTION 7
What is the maximum supporter number of vCPU per VM in VMware vSphere 6.5?

• A. 246
• B. 128
• C. 64
• D. 32

Answer: B

NEW QUESTION 8
In vSphere 6.5, a virtual machine is thinly-provisioned on a VMFS6 datastore. The administrator deleted a large file within the guest OS. The freed blocks in the datastore are no longer needed by the VM.
Which feature in vSphere 6.5 allows the backing storage to automatically reclaim the freed blocks?

• A. ATS
• B. Defrag
• C. UNMAP
• D. Auto Reclaim

Answer: C

Explanation: VAAI UNMAP was introduced in vSphere 5.0 to allow the ESXi host to inform the backing storage that files or VMs had be moved or deleted from a Thin Provisioned VMFS datastore. This allowed the backing storage to reclaim the freed blocks. There was no way of doing this previously, resulting in many customers with a
considerable amount of stranded space on their Thin Provisioned VMFS datastores.

NEW QUESTION 9
The virtual machine log rotation size can be changed for all VMs by which two interfaces? (Choose two.)

• A. vSphere Web Client
• B. ESXi host client
• C. esxcli
• D. PowerCLI

Answer: AD

NEW QUESTION 10
An administrator procured a new server on which to install ESXi 6.5. The server is equipped with localSerial Attached SCSI (SAS) disks with 512e format (512bytes sector emulation).
Which file system does VMware support on this type of disk?

• A. VMFS6 (default) and VMFS5
• B. VMFS5
• C. 512e format is not supported
• D. VMFS6

Answer: A

NEW QUESTION 11
Which two statements correctly describe VM-VM affinity rules? (Choose two.)

• A. vSphere DRS attempts to keep the virtual machines together on the same ESXi host.
• B. When two VM-VM affinity rules conflict, the older one takes precedence and the newer rule is disabled.
• C. vSphere DRS attempts to keep the virtual machines on separate ESXi hosts.
• D. When two VM-VM affinity rules conflict, the newer one takes precedence and the older rule is disabled.

Answer: AB

NEW QUESTION 12
What are two requirements to enable EVC in a vSphere DRS cluster? (Choose two.)

• A. CPUs must be from the same vendor.
• B. CPUs must be in the same family and of the same speed.
• C. No VMs may be running in the cluster.
• D. EVC must use the lowest possible baseline supported by the hardware.

Answer: AD

NEW QUESTION 13
On a cluster of ESXi 6.5 hosts, a small number of virtual machines have much larger resource requirements than others. Some hosts have a large number of virtual machines while others have very few.
The administrator enables DRS with DRS VM distribution to evenly balance the number of virtual machines on each host.
Which will be the outcome?

• A. Virtual machines will be moved without regard to resource contention in the cluster, and the virtual machine distribution will become evenly balanced.
• B. Virtual machines will not change hosts unless they are power-cycled or vMotioned manually.
• C. Virtual machines will not be moved if it results in severe resource contention in the cluster, and the virtual machine distribution will remain unbalanced.
• D. DRS VM distribution will not evenly balance the number of virtual machines on each host unless anti-affinity rules are applied.

Answer: A

NEW QUESTION 14
The Health Check feature in the vSphere Distributed Switch helps troubleshoot network connectivity. What three checks does this feature perform? (Choose three.)

NEW QUESTION 15
A vSphere administrator upgraded vCenter Server (VC) from version 5.5 to 6.5. Existing VMFS5 datastores consumption is 75% full. All of the ESXi hosts have been upgraded to version 6.5. Existing datastores have not yet been upgraded.
Which is VMware’s recommended approach to upgrading each VMFS5 datastore to VMFS6?

• A. The option to upgrade datastores to VMFS6 is only available during the ESXi host upgrade process.
• B. Log on one ESXi host at a time using vSphere 6.5 Windows Clien
• C. Navigate to the datastores view.Right-click on the VMFS5 datastore, and then select upgrade to VMFS6.
• D. Log on to VC using vSphere 6.5 Web Clien
• E. Navigate to the datastores vie
• F. Right-click on the VMFS5 datastore, and then select upgrade to VMFS6.
• G. Log on to VC using vSphere 6.5 Web Clien
• H. Create a VMFS6 datastore on a new LU
• I. Use storage vMotion to migrate the data to the new datastore.

Answer: D

Explanation: Perform version check for the vCenter Server and all ESX hosts.
Note: All ESXi hosts and vCenter Server must be of vSphere 6.5. Do not proceed if any one of ESXi hosts is not vSphere 6.5. Proceeding further means business continuity loss and the new datastore is not visible in old ESX hosts.
Perform all pre checks for free space availability on datastore DS-2. Available space on DS-2 must be equal or more than the datastore DS-1 space.
Ensure that the datastore DS-2 is VMFS 6 type.
Prepare list of all virtual machines in the vCenter Server’s inventory that are hosted on datastore DS-1. Evacuate the datastore DS-1. For this, migrate all the virtual machines running from datastore DS-1 to
datastore DS-2. Storage vMotion operations are performed on these virtual machines.
Perform one migration at a time to avoid disrupting the performance of remaining datacenter entities. Keep track of any migration failures, if any, re-trigger the migration for those virtual machines.
Ensure that datastore DS-1 is empty by listing files on this datastore. Note: Proceed further only if datastore DS-1 is empty.
Unmount datastore DS-1 from all ESX hosts. Delete datastore DS-1.
Create a new datastore with the VMFS 6 filesystem using the same lun. For example, DS-1.
Trigger a storage rescan operation on all hosts and wait for few minutes for this operation to complete.
Move all virtual machines back to datastore DS-1 from datastore DS-2 by performing storage vMotion operation. It is suggested to migrate one virtual machine at a time. Keep track of any migration failures, if any, re-trigger migration for those virtual machines.

NEW QUESTION 16
An administrator sets the Failover Capacity for both CPU and Memory at 25%. Based on the Exhibit below, how much of the cluster's total CPU resources are still available to power on additional virtual machines?

• A. 45%
• B. 60%
• C. 70%
• D. 25%

Answer: A

Explanation: The way that Current Failover Capacity is calculated and used with this admission control policy is shown with an example. Make the following assumptions about a cluster: The cluster is comprised of three hosts, each with a different amount of available CPU and memory resources. The first host (H1) has 9GHz of available CPU resources and 9GB of available memory, while Host 2 (H2) has 9GHz and 6GB and Host 3 (H3) has 6GHz and 6GB. There are five powered-on virtual machines in the cluster with differing CPU and memory requirements. VM1 needs 2GHz of CPU resources and 1GB of memory, while VM2 needs 2GHz and 1GB, VM3 needs 1GHz and 2GB, VM4 needs 1GHz and 1GB, and VM5 needs 1GHz and 1GB. The Configured Failover Capacity is set to 25%.Admission Control Example with Percentage of Cluster Resources Reserved Policy
The total resource requirements for the powered-on virtual machines is 7GHz and 6GB. The total host
resources available for virtual machines is 24GHz and 21GB. Based on this, the Current CPU Failover Capacity is 70% ((24GHz – 7GHz)/24GHz). Similarly, the Current Memory Failover Capacity is 71% ((21GB-6GB)/21GB).Because the cluster’s Configured Failover Capacity is set to 25%, 45% of the cluster’s total CPU resources and 46% of the cluster’s memory resources are still available to power on additional virtual machines.
