VMware VCP6.5-DCV 2V0-622 Questions & Answers

• Question 241:

  Which statement is true regarding Network-Aware DRS?

  A. Network-Aware DRS will perform load-balancing based on the communication of virtual machines with one another.

  B. Network-Aware DRS is enabled through DRS advanced options.

  C. Network-Aware DRS only generated suggested moves; administrators must go in and accept each Network-Aware DRS suggestion manually.

  D. Network-Aware DRS will perform a final check during regular DRS load-balancing to ensure that the destination host is not network saturated.

  Correct Answer: D

• Question 242:

  On which level is the virtual machine system traffic reservation defined in Network I/O Control version 3?

  A. Uplink

• Question 243:

  When working with VM-VM DRS rules (affinity/anti-affinity), which statement is correct?

  A. DRS gives higher priority to preventing violations of affinity rules than violations of anti-affinity rules.

  B. DRS gives the same priority to preventing violations of anti-affinity rules as affinity rules.

  C. DRS does not allow both affinity and anti-affinity rules to be enabled at the same time within a cluster.

  D. DRS gives higher priority to preventing violations of anti-affinity rules than violations of affinity rules.

  Correct Answer: A

  When two VM-VM affinity rules conflict, the older one takes precedence and the newer rule is disabled. DRS only tries to satisfy enabled rules and disabled rules are ignored. DRS gives higher precedence to preventing violations of anti- affinity rules than violations of affinity rules.

• Question 244:

  An administrator is trying to add a new virtual disk of 3TB to a virtual machine on a recently upgraded ESXi

  6.x

  host, but receives this error:

  The disk capacity entered was not a properly formed number or was out of range. It has been replaced

  with the nearest acceptable value.

  How can the new virtual disk be added to the virtual machine?

  A.

  Upgrade the VMFS datastore.

  B.

  Change the VMFS datastore block size to 8MB.

  C.

  Move the virtual machine to a datastore with free space.

  D.

  Use vmkfstools to upgrade to VMFS6.

  Correct Answer: B

• Question 245:

  An administrator is configuring vCenter HA and considering placing the Passive and Witness nodes in

  another datacenter from the Active Node.

  Which is the maximum supported latency between the vCenter HA nodes?

  A. 5ms

  B. 10ms

  C. 100ms

  D. 30ms

  E. 50ms

  Correct Answer: B

  vCenter HA network latency between Active, Passive, and Witness nodes must be less than 10 ms. Reference:https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.avail.doc/GUID8FD87389-8CC9-4298-8B08-A1526FB44524.html

• Question 246:

  An ESXi host has be

  en placed into Quarantine Mode by Proactive HA.

  What will happen?

  A. Virtual machines will be migrated off the quarantines host if doing so will not violate any DRS affinity and anti-affinity rules or cause increased resource contention.

  B. Newly powered-on virtual machines may be placed on the quarantined host to balance cluster resources. Already powered-on virtual machines will be migrated off of the quarantined host if doing so will not violate any DRS affinity and anti- affinity rules or cause resource contention.

  C. All virtual machines will be migrated off the quarantined host to other hosts in the cluster without regard to DRS rules.

  D. vSphere HA will conduct a failover on all VMs residing on the quarantined host.

  Correct Answer: A

  Proactive HA - Proactive HA integrates with select hardware partners to detect degraded components and evacuate VMs from affected hosts before an incident can cause an interruption of service. vCenter Server plug-ins from the hardware vendors provide the health status of hosts' system memory, local storage, power supplies, cooling fans, and network adapters. If components become degraded, Proactive HA determines which hosts are at risk and places them into a new-to- 6.5 state called "Quarantine Mode". While in Quarantine Mode, VMs are migrated off of the host onto healthy hosts (as long as affinity and anti-affinity rules are not violated, and the performance of the VM will not be negatively affected). New VMs will not be added to hosts that are in Quarantine Mode.

• Question 247:

  In vCenter Server 6.5, which two host states can be configured as remediation steps with Proactive HA? (Choose two.)

  A. Maintenance mode

  B. Disconnected

  C. Powered off

  D. Standby mode

  E. Quarantine mode

  Correct Answer: AE

  Proactive HA Failures A Proactive HA failure occurs when a host component fails, which results in a loss of redundancy or a noncatastrophic failure. However, the functional behavior of the VMs residing on the host is not yet affected. For example, if a power supply on the host fails, but other power supplies are available, that is a Proactive HA failure. If a Proactive HA failure occurs, you can automate the remediation action taken in the vSphere Availability section of the vSphere Web Client. The VMs on the affected host can be evacuated to other hosts and the host is either placed in Quarantine mode or Maintenance mode. References:

• Question 248:

  Which are three prerequisites for using UEFI secure boot? (Choose three.)

  A. Virtual machine with EFI firmware

  B. Virtual Hardware version 12

  C. Virtual Machine with BIOS firmware version 6

  D. Virtual Hardware version 13

  E. Operating system that supports UEFI secure boot

  Correct Answer: ADE

  Verify that the virtual machine operating system and firmware support UEFI boot. EFI firmware

  Virtual hardware version 13 or later.

  Operating system that supports UEFI secure boot.

  You need VirtualMachine.Config.Settings privileges to enable or disable UEFI secure boot for the virtual

  machine.

• Question 249:

  A vSphere administrator wants to reserve 0.5Gbps for virtual machines on each uplink on a distributed

  switch that has 10 uplinks.

  What is the quota that should be reserved for the network resource pool?

  A. 5Gbps

  B. 10Gbps

  C. 100Gbps

  D. 0.5Gbps

  Correct Answer: A

  For example, if the virtual machine system traffic has 0.5 Gbps reserved on each 10 GbE uplink on a distributed switch that has 10 uplinks, then the total aggregated bandwidth available for VM reservation on this switch is 5 Gbps. Each network resource pool can reserve a quota of this 5 Gbps capacity.

• Question 250:

  Boot from SAN is supported on which three storage technologies? (Choose three.)

  A. iSCSI

  B. NFS 4.1

  C. FC

  D. VMware vSAN

  E. FCoE

  Correct Answer: ACE
