• Question 252:

  A vSphere 5.x implementation contains two ESXi hosts, ESXi01and ESXi02. There is a virtual machine "VM21" connected to the Production port group on ESXi01.

  ESXi01 has the following switch configuration. vSwitch0, single uplink to 10.1.20.0/24 Production port group VMkernel port for vMotion VMKernel port for management vSwitch1, single uplink to 10.1.40.0/24 Engineering port group VMKernel port for NFS storage

  ESXi02 has the following switch configuration. vSwitch0, single uplink to 10.1.20.0/24 Engineering port group VMkernel port for vMotion VMKernel port for management vSwitch1, single uplink to 10.1.40.0/24 Production port group VMKernel port for NFS storage

  Which two statements are true about this configuration? (Choose two.)

  A. vMotion is not available between the two hosts

  B. If VM21 is migrated to ESXi02 it will not be available on the network

  C. The virtual machine can be vMotion migrated to the target host.

  D. Broadcasts from the Production port group will not reach the Engineering port group.

  Correct Answer: BD

• Question 253:

  The performance graph for a virtual machine with 1GB of RAM shows the Swap In rate to be 150 MBps and the Balloon value to be at 0 MB . Users of the virtual machine are complaining that performance is slow. Which two actions could increase performance of the virtual machine? (Choose two.)

  A. Install the VMMEMCTL driver on the ESXi host.

  B. Increase the memory share value for this virtual machine.

  C. Install VMware Tools into this virtual machine.

  D. Disable swapping in the virtual machine operating system.

  Correct Answer: BC

• Question 254:

  Which two components can be installed in monitored virtual machines to trigger vSphere HA Application Monitoring? (Choose two.)

  A. A custom script utilizing the appmonitor executable

  B. The vSphere Fault Tolerant agent

  C. Third-party utilities such as Neverfail or ApplicationHA

  D. The vSphere HA application agent

  Correct Answer: AD

• Question 255:

  A database administrator has reported periodic poor performance on a particular virtual machine. The virtual machine administrator has noticed a significant drop in performance when utilized memory exceeds 1GB . What does this indicate and what could be checked next?

  A. The application problems are definitely due to a non-memory-related problem. CPU affinity settings should be checked for this virtual machine.

  B. The application problems are definitely due to a non-memory-related problem. CPU utilization should be checked next, using Windows Task Manager.

  C. The virtual machine might not have physical memory available. Compression and swap activity on the ESXi host should be checked next.

  D. The virtual machine might not have physical memory available. Ensure the memory limit on the VM is set to 0 MB

  Correct Answer: C

• Question 256:

  What would be a valid reason to enable traffic shaping?

  A. Limiting the bandwidth of a FTP server

  B. Restricting the load on a IDS server

  C. Limiting the bandwidth used by an independent hardware iSCSI adapter

  D. Improving the performance of a CPU-intensive application server

  Correct Answer: A

• Question 257:

  Users have reported performance issues with an application running on a Windows VM. Performance analysis shows high CPU activity on the ESXi host but low CPU activity on the Windows VM.A high value in which overview graph and counter on the virtual machine's Performance tab would confirm the results of the performance analysis?

  A. CPU (%) / Wait

  B. CPU Usage (Mhz) / Wait

  C. CPU Usage (Mhz) / Ready

  D. CPU (%) / Ready

  Correct Answer: D

• Question 258:

  Which option could be used for vSphere HA heartbeats?

  A. An iSCSI LUN used for booting the master ESXi host.

  B. An iSCSI LUN backing an RDM connected over 10GB Ethernet

  C. An NFS datastore shared with the all hosts, sync, no_root_squash and read only options

  D. A Fibre Channel LUN on an 8GB active/active array backing a VMFS5 datastore

  Correct Answer: D

• Question 259:
