• Question 282:

  Click the Exhibit button.

  

  ACME Party Supplies Corporation has a requirement to monitor all virtual machines in a vSphere 5 environment for CPU and Memory usage. An administrator configures an alarm in vCenter Server to send an alert when any VM exceeds 65% memory utilization and 75% CPU utilization. The alarm should warn administrators if the virtual machine is within 20% of the defined thresholds. The alarm has been created with the default options as shown in the exhibit.

  Which three modifications must be made to the default settings in the alarm definition to satisfy the stated requirements? (Choose three.)

  A. Set the VM CPU Usage (%) Alert trigger to 75% and the VM Memory Usage (%) Alert trigger to 55%

  B. Set the VM CPU Usage (%) Alert trigger to 75% and the VM Memory Usage (%) Warning trigger to 55%

  C. Set the VM CPU Usage (%) Warning trigger to 65% and the VM Memory Usage (%) Warning trigger to 45%

  D. Set the Trigger if all of the conditions are satisfied radio button

  E. Set the Trigger if any of the conditions are satisfied radio button

  Correct Answer: ACE

  You need to set the VM Cpu usage alert trigger to 75% and VM memory usage alert trigger to 55%. Warning trigger should be at 65% and VM memory usage warning trigger to 45%. Check the radio button trigger if any of the conditions are satisfied.

• Question 283:

  Which three statements regarding Network I/O Control (NIOC) are accurate? (Choose three.)

  A. NIOC enforces traffic bandwidth limits on the overall vDS set of dvUplinks.

  B. NIOC limits maximum throughput control on connected virtual machines.

  C. Load based teaming efficiently uses a vDS set of dvUplinks for network capacity.

  D. Isolation provides priority to any one traffic flow.

  E. Relative shares fairly allocates available bandwidth among multiple flows.

  Correct Answer: ACE

• Question 284:

  A company has converted several physical machines to virtual machines but are seeing significant performance issues on the converted machines. The host is configured with sufficient memory and storage does not appear to be a bottleneck. Which metric can be checked to determine if CPU contention exists on an ESXi 5.x host?

  A. %RUN

  B. %WAIT

  C. %USED

  D. %RDY

  Correct Answer: D

• Question 285:

  An administrator receives a complaint that a virtual machine is performing poorly. The user attributes the issue to poor storage performance. If the storage array is the bottleneck, which two counters would be higher than normal? (Choose two.)

  A. Average ESXi VMKernel latency per command, in milliseconds

  B. Average ESXi highest latency, in milliseconds

  C. Average virtual machine operating system latency per command, in milliseconds

  D. Number of SCSI reservation conflicts per second

  Correct Answer: BC

  When the storage array is performing poorly or became a bottleneck, you will see the average ESXi highest latency in milliseconds. Moreover, the average virtual machine operation system latency per command will be high in milliseconds.

• Question 286:

  An administrator notices that log files kept on an ESXi 5.x host are being rotated very quickly, inhibiting the troubleshooting of an issue. Which two configuration changes will resolve the issue? (Choose two.)

  A. Configure syslog to send the logs a syslog server

  B. Increase the number of logs kept

  C. Increase the logging level

  D. Increase the size of the partition where log files are stored

  Correct Answer: AB

  Configure syslog to send logs to syslog server and increase the number of logs kept. This way, the log files are not rotated very quickly.

• Question 287:

  An administrator has created a virtual machine that will be accessed from a public kiosk. Management has requested that the virtual machine be reset to a known state once a week or on demand if requested. Which method is the simplest way to meet this requirement?

  A. Configure the storage array to be vSphere aware and script routine array snapshot restores of the datastore.

  B. Implement a 3rd party imaging server and PXE boot the virtual machine off a static image.

  C. Set the VMDKs of the virtual machine to be Independent-Nonpersistent and schedule restarts of the virtual machine.

  D. Create Nonpersistent disks for the virtual machine and set the guest OS to reboot once a week.

  Correct Answer: C

• Question 288:

  Which three Storage I/O Control conditions might trigger the Non-VI workload detected on the datastore alarm? (Choose three.)

  A. The datastore is connected to an ESX/ESXi 4.0 host that does not support Storage I/O Control.

  B. The datastore is on an array that is performing system tasks such as replication.

  C. The datastore is utilizing active/passive multipathing or NMP (Native Multi-Pathing).

  D. The datastore is storing virtual machines with one or more snapshots.

  E. The datastore is connected to an ESX/ESXi 4.0 host that is not managed by vCenter.

  Correct Answer: ABE

• Question 289:

  An administrator notices that when a virtual machine is placed into a resource pool, a warning indicates that the virtual machine will receive a very large percentage of the total shares for memory. Which action can be taken to resolve this problem?

  A. Increase the memory resource allocation to the resource pool.

  B. Increase the share value for the resource pool.

  C. Change the shares setting from custom to high, medium, or low for the virtual machine.

  D. Decrease the memory allocation for the virtual machine.

  Correct Answer: C

  The Memory Resources panel lets you allocate memory resources for a virtual machine and specify reservations, limits, and shares. Symbolic values Low, Normal, High, and Custom are compared to the sum of all shares of all virtual machines on the server and, on an ESX host, the service console. By decreasing the memory share of a particular system, it receives less memory out of the total available memory.

• Question 290:

  Click the Exhibit button.

  

  Several virtual machines residing in the Production pool are exhibiting poor performance, and a critical virtual machine in the pool appears hung. What step can be taken to increase the performance of the critical virtual machine?

  A. Increase the CPU limit on the critical virtual machine.

  B. Increase the CPU shares on the critical virtual machine.

  C. Increase the CPU reservations on the resource pool.

  D. Increase the CPU limit on the resource pool.

  Correct Answer: D

  It seems the CPU limit is the culprit. Increase the CPU limit on the resource pool.
