VMware VMware Certifications VCP550 Questions & Answers

• Question 11:

  The load is high on a HA/DRS cluster. DPM is enabled. A vSphere administrator determines that hosts are NOT powering on automatically to support the load. Which configuration would result in this condition?

  A. VM-to-VM or VM-to-Host DRS rules have been configured that restrict where some VMs can be moved.

  B. DPM has been set to the most Conservative threshold.

  C. Some of the virtual machines have been removed from HA consideration by the vSphere administrator.

  D. DRS is set to Manual Automation.

  Correct Answer: D

• Question 12:

  A virtual machine fails to migrate during a Storage DRS event. What could cause this issue?

  A. Storage DRS is enabled for the datastore cluster but disabled for the virtual disks.

  B. Storage DRS is enabled, but vMotion is disabled for the affected virtual machine.

  C. The vMotion network used for Storage DRS is down for a host in the cluster.

  D. Storage DRS is attempting to migrate the virtual machine between VMFS and NFS datastores.

  Correct Answer: A

• Question 13:

  A vSphere administrator enables and configures a Software iSCSI Initiator, and configures an iSCSI vmkernel portgroup with Port Binding. The SAN administrator creates a few LUNs on an iSCSI server. However, when the vSphere administrator adds the IP address of the iSCSI server in the Dynamic Discovery list, no iSCSI targets are detected.

  What condition would result in this behavior?

  A. The iSCSI vmkernel portgroup and the iSCSI server are on different subnets.

  B. The iSCSI server IP address should be entered in the Static Discovery instead of Dynamic Discovery list.

  C. The network card bound to the iSCSI portgroup is 1Gbps Ethernet instead of 10Gbps.

  D. A Software iSCSI Initiator cannot use Port Binding in conjunction with Dynamic Discovery.

  Correct Answer: A

• Question 14:

  An administrator is using esxtop to troubleshoot a storage performance issue.

  Which parameter should the administrator check to monitor any storage-related vSphere overhead?

  A. DAVG

  B. KAVG

  C. GAVG

  D. CMDS

  Correct Answer: B

• Question 15:

  An error occurs while building a new virtual machine with a thin provisioned virtual disk size of 20GB. The datastore has 35GB of free space. The datastore is overcommitted by 95GB. What is preventing the virtual machine from being built?

  A. The datastore is built on a thin provisioned LUN that has run out of storage array free space.

  B. The datastore has reached the maximum overcommitment threshold.

  C. The virtual disk used by the virtual machine cannot be thin provisioned on this datastore.

  D. The virtual disk used by the virtual machine requires more free space than is available in the datastore.

  Correct Answer: A

• Question 16:

  A SAN administrator recently installed a storage encryption switch on the Fibre Channel Fabric. Shortly after the deployment, several new VMFS5 datastores recently created were dismounted. Attempts to manually mount them fail. VMFS5 upgraded datastores are unaffected. All Storage arrays in use support VASA and VAAI.

  What is the root cause of this problem?

  A. All newly created VMFS5 datastores are tagged ATS_Only. The storage encryption switch blocks the ATS command.

  B. All newly created VMFS5 datastores are tagged XCOPY_Only. The storage encryption switch blocks the XCOPY command.

  C. All newly created VMFS5 datastores are tagged WRITE_SAME_Only. The storage encryption switch blocks the WRITE_SAME command.

  D. All newly created VMFS5 datastores were formatted with 1MB block size. The storage encryption switch does not support this block size.

  Correct Answer: A

• Question 17:

  -- Exhibit -

  

  -- Exhibit -

  An administrator receives notice of a large number of ARP table issues. The issues began after a maintenance window 36 hours ago. The issue did not exist prior to the maintenance

  window.

  Which change was made to the port group that is causing the ARP table issue?

  A. Notify Switches was changed to No.

  B. Uplink 2 was changed from Standby to Active.

  C. Failback was changed to Yes.

  D. Network failure detection was changed to Link status only.

  Correct Answer: A

• Question 18:

  -- Exhibit -

  

  -- Exhibit -A vSphere administrator attempts to manually vMotion a virtual machine but receives error messages related to the Shared Storage datastore shown in the exhibit.

  The administrator uses the vSphere Web Client and locates the datastore settings shown:

  Which action should the administrator take to resolve these errors?

  A. Reconnect server3 to the vCenter server.

  B. Select server3 and click Mount.

  C. Remove server3 from the cluster then re-add it.

  D. Right-click Not connected and select Connect.

  Correct Answer: B

• Question 19:

  -- Exhibit -

  

  -- Exhibit -An ESXi host's networking is configured as shown. The virtual machine named Fileserver01 is unable to ping anything on an external network:

  Which condition would explain this behavior?

  A. The vSwitch1 virtual switch does not have an attached vmnic adapter.

  B. The Fileserver01 virtual machine is not running.

  C. vSwitch0 is configured to reject MAC address spoofing.

  D. vmk0 is using a non-routable IP address.

  Correct Answer: B

• Question 20:

  A security audit has revealed that a virtual machine on vSwitch1 is receiving all traffic sent to the virtual switch, violating corporate policy. The vSphere administrator examines the properties for vSwitch1, as shown in the exhibit: -- Exhibit -

  

  -- Exhibit -Which configuration explains why the virtual machine is receiving all traffic sent to vSwitch1?

  A. The Production port group has the Promiscuous Mode policy set to Accept.

  B. vSwitch1 has the Promiscuous Mode policy set to Reject.

  C. The Network Failure Detection policy on the Production port group is set to Link Status plus Beaconing.

  D. The Network Failure Detection policy on vSwitch1 is set to Link Status only.

  Correct Answer: A
