VMware VCP6-DCV 2V0-621D Questions & Answers

• Question 91:

  An administrator is upgrading an ESXi 5.5 host to ESXi 6.x and gets the following error:

  MEMORY_SIZE

  What does this indicate?

  A. Insufficient memory on the ESXi host to complete the upgrade.

  B. Insufficient memory for Auto Deploy to complete the upgrade.

  C. Insufficient memory in vCenter Server to complete the upgrade.

  D. Insufficient memory for Update Manager to complete the upgrade.

  Correct Answer: A

  When you install less than 4GB of memory, Memory_Size error occurs because ESXi host requires at least 4 GB of memory.

• Question 92:

  An administrator is troubleshooting network communications between the vCenter Server and the ESXi 6.x host. Which log shows the interaction events between these components?

  A. /var/log/syslog.log

  B. /var/log/hostd.log

  C. /var/log/vpxa.log

  D. /var/log/fdm.log

  Correct Answer: C

  When an ESXi 5.1 / 5.5 host is managed by vCenter Server 5.1 and 5.5, two components are installed, each with its own logs:

  /var/log/vpxa.log: vCenter Server vpxa agent logs, including communication with vCenter Server and the Host Management hostd agent. /var/log/fdm.log: vSphere High Availability logs, produced by the fdm service.

• Question 94:

  The command esxcli network vm list displays four virtual machines connected to the Production vSwitch. Within the vSphere Web Client, five virtual machines are seen. What explains this behavior?

  A. The fifth virtual machine is currently powered off.

  B. The fifth virtual machine has two vnics.

  C. The fifth virtual machine has an invalid IP address.

  D. The fifth virtual machine has an invalid MAC address.

  Correct Answer: A

  The vSphere client shows all the virtual machines whether they are powered on or off. The fifth virtual machine in this scenario might be powered off. Esxcli network list display virtual machines that are active.

• Question 95:

  A. The files will be unchanged.

  B. The files will be deleted.

  C. The files will remain and be marked as orphaned.

  D. The containing folder will be marked as orphaned.

• Question 96:

  An administrator is experiencing network connectivity issues between virtual machines. The virtual machines and hosts are configured as follows:

  VM1 is running on Host1 VM2 is running on Host2 Both Host1 and Host2 are attached to the vSphere Distributed Switch dvSwitch1 Both Host1 and Host2 are using vmnic0 and vmnic1 on dvSwitch1 Both virtual machines are using the default portgroup for network traffic

  What are three settings the administrator should investigate while troubleshooting the connectivity issue? (Choose three.)

  A. VLANs of the physical NICs

  B. Failover order of the uplinks

  C. Virtual NIC connectivity to the dvSwitch

  D. Security policy of the portgroup

  E. Traffic shaping on the portgroup

  Correct Answer: ABC

  To find out connectivity problems, you can use VLANs of the physical NICs, virtual MIC connectivity to the dvswitch and failover orders of the uplinks.

• Question 97:

  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.)

  A. Increase the memory reservation of the virtual machine.

  B. Increase the CPU Shares on the resource pool where the virtual machine resides.

  C. Decrease the CPU reservation of the virtual machine.

  D. Increase the CPU limit on the resource pool where the virtual machine resides.

  Correct Answer: BD

  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 98:

  Refer to the Exhibit.
