Question No: 111 – (Topic 6)
When importing an existing SSL certificate into vSphere Replication Server, which file format is required?
Answer: A Explanation:
vSphere Replication can only import and use certificates and private keys from a file in the PKCS#12 format. Sometimes these files have a .pfx extension.

Which three statements are true when restoring a Resource Pool Tree? (Choose three.)
Distributed Resource Scheduler must be set to manual.
Restoring a snapshot can only be done on the same cluster from which it was taken.
No other resource pools can be present in the cluster.
Restoring a resource pool tree must be done in the vSphere Web Client.
Enabling Enhanced vMotion Compatibility on the cluster is required.

An administrator notices that 8 out of 10 virtual machines have memory ballooning and swapping. However, virtual machine 9 is not ballooning or swapping and virtual machine 10 is not ballooning but is swapping.
Which two statements explain the behavior of virtual machine 9 and virtual machine 10? (Choose two.)
Virtual machine 9 has a 100% memory reservation.
Virtual machine 10 has a memory limit configured.
Virtual machine 9 has memory shares set to HIGH.
Virtual machine 10 does not have Vmware Tools enabled or installed.
It seems that VM 9 has 100% memory reservation and VM 10 has a memory limit configured.

An administrator is troubleshooting a virtual machine performance issue using vRealize Operations.
Which two badges would help to identify possible resource contention concerns? (Choose two.)
Health gt; Workload
Health gt; Faults
Risk gt; Time Remaining
Risk gt; Stress

Question No: 116 – (Topic 7)
Refer to the Exhibit.
An administrator is reviewing a vSphere Distributed Resource Scheduler (DRS) enabled Cluster and observes unexpected behavior as shown in the Exhibit.
What are three potential causes of the cluster imbalance? (Choose three.)
A local device is mounted to one or more virtual machines.
DRS rules prevent virtual machines from being moved.
vMotion is not configured and enabled.
There are insufficient cluster resources to perform the migration.
DRS has been configured for a conservative migration threshold.
Answer: A,B,C Explanation:
Cluster imbalance is often caused by a local device mounted to one or more VMs and the DRS rules are preventing the VMs from being moved. Similarly, check vMotion to see if it is configured and enabled.
Question No: 117 – (Topic 7)
An administrator is troubleshooting a performance problem with a virtual machine (VM). The VM and ESXi host configuration is as follows:
->The application which runs within the virtual machine is highly sensitive to memory latency, but has low processor utilization.
->The virtual machine has 6 vCPUs.
->The ESXi host CPU topology has 2 Physical CPU Sockets, each with 8 Logical CPUs.
->The ESXi host CPU has Hyper Threading enabled.
The administrator would like to improve CPU performance for this VM. Other VMs on the host have no performance issues. Which action should the administrator take to resolve the issue?
Set the Advanced Parameter numa.vcpu.preferHT = TRUE in the virtual machine configuration file.
Set the Advanced Parameter numa.vcpu.preferHT = FALSE in the virtual machine configuration file.
Set the Advanced Parameter numa.PreferHT = 1 in the ESXi host configuration file.
Set the Advanced Parameter numa.PreferHT = 0 in the ESXi host configuration file.
Answer: A Explanation:
Set advanced parameter numa.vcpu.preferHT = TRUE in the VM configuration file to increase CPU performance.
Question No: 118 – (Topic 7)
Which condition would cause a vCenter Server installation to fail when installing on a Windows virtual machine?
The virtual machine does not have at least four vCPUs.
The virtual machine is running Windows Server 2008.
The virtual machine has an E1000 network device.
The virtual machine does not have 16GB of RAM.
Answer: B Explanation:
If you use Simple Install to install vCenter Server and components on a Windows Server 2008 R2 or Windows 2012 host, and the host is configured to use DHCP IP addressing, the installation fails with warning and error messages.

Question No: 119 – (Topic 7)
An administrator notices that a Windows virtual machine is using 95% CPU in Task Manager.
Which two actions should be taken to resolve this issue? (Choose two.)
Increase the memory reservation of the virtual machine.
Increase the CPU Shares on the resource pool where the virtual machine resides.
Decrease the CPU reservation of the virtual machine.
Increase the CPU limit on the resource pool where the virtual machine resides.
Answer: B,D Explanation:
There are two ways to resolve high CPU usage. First increase CPU shares on resource pool where the VM resides. Secondly, increase CPU limit on the resource pool that serves the concerned VM.
Question No: 120 – (Topic 7)
Refer to the Exhibit.
An administrator receives the error message shown in the Exhibit. Which two actions can be taken to clear the warning? (Choose two.)
Add a Virtual SAN datastore and configure it for High Availability heartbeating.
Set the advanced High Availability parameter Das.heartbeatdsperhost to 1.
Set the advanced High Availability parameter Das.ignoreInsufficientHbDatastore to true.
Add a shared datastore and reconfigure High Availability.
