VMware VCP5-DCV Online Questions & Answers

• Question 481:

  A vSphere administrator has created a vSphere Standard Switch with one virtual machine port group and one physical uplink. The administrator needs to ensure that the virtual machines on this port group can communicate only with each

  other.

  What should the administrator do?

  A. Remove the physical uplink from the vSphere Standard Switch
  B. Create a Private VLAN and apply it to the virtual machine port group on the vSphere Standard Switch
  C. Enable Port Security on the vSphere Standard Switch
  D. Enable the Fenced setting on the virtual machine port group
  A. Remove the physical uplink from the vSphere Standard Switch

• Question 482:

  It appears that a single vCPU virtual machine in a resource pool called Production is having performance problems because it does not have enough CPU resources available. Which two methods can be used to improve performance and reduce CPU contention of this virtual machine while maintaining compatibility with DRS? (Choose two.)

  A. Configure a CPU reservation for this virtual machine.
  B. Increase the CPU shares for the resource pool.
  C. Increase the CPU shares for the virtual machine.
  D. Increase the share priority setting for the Production resource pool.
  A. Configure a CPU reservation for this virtual machine.
  C. Increase the CPU shares for the virtual machine.

  ---

  Explanation/Reference:

  To improve performance and reduce CPU contention of this virtual machine, you need to configure a CPU reservation and increase CPU shares for this virtual machine.

• Question 483:

  A user wants to receive an email notification when the virtual machine CPU usage enters a warning state and again when the condition enters a alarm state. Which two state changes must be selected to receive the appropriate notifications? (Choose two.)

  A. Yellow-red state change
  B. Red-green state change
  C. Yellow-green state change
  D. Green-yellow state change
  A. Yellow-red state change
  D. Green-yellow state change

• Question 484:

  An administrator is configuring a stretched HA cluster. The administrator wishes to restrict the failover of VMs to certain hosts within a given site. Which additional vSphere feature satisfies this requirement?

  A. vSphere Distributed Switch
  B. Distributed Resource Scheduler
  C. Datastore Clusters
  D. Host Folders
  B. Distributed Resource Scheduler

• Question 485:

  An administrator has created a Virtual Flash Read Cache and needs to add a total 2TB of capacity to the cache. The administrator has a total of six SSD disks to add, but is unable to add one of the disks. What is a likely cause of the problem?

  A. The SSD device size is less than 256GB.
  B. The SSD device size is greater than 4TB.
  C. The SSD device is a local disk.
  D. The SSD device contains existing data.
  B. The SSD device size is greater than 4TB.

• Question 486:

  Which action should an administrator take to increase the size of a VMFS5 datastore from 2TB to 32TB?

  A. Dynamically expand the original LUN and add a second share for the NFS datastore
  B. Dynamically expand the original LUN and increase the size of the VMFS datastore
  C. Dynamically expand the original LUN and add extents to the VMFS datastore
  D. Dynamically expand the original LUN and add extents to the NFS datastore
  B. Dynamically expand the original LUN and increase the size of the VMFS datastore

• Question 487:

  Which of these factors indicates a high likelihood that the performance of a virtual machine disk is being constrained by disk I/O?

  A. A large number of commands issued
  B. A high device latency value
  C. A high disk used value
  D. A large number of kilobytes read and written
  B. A high device latency value

  ---

  Explanation/Reference:

  Disk performance bottlenecks are usually due to either Disk queue length or Disk Latency

• Question 488:

  Which is an important benefit provided by VLANs?

  A. Reduced hardware requirements
  B. Increased broadcast traffic
  C. Fault tolerance
  D. Increased security on a network segment
  A. Reduced hardware requirements

  ---

  Explanation/Reference:

  VLANs are virtual local area networks. They significantly reduce costs by saving money that can be spent on the purchase of switches, hubs and routers.

• Question 489:

  Which configuration will block communication between two virtual machines on the same DMZ network?

  A. An isolated Private VLAN configured on a distributed switch and the two DMZ server virtual machines connected to the same port group
  B. Two different port groups created on a distributed switch and 1 DMZ server virtual machine connected to each port group
  C. Two different port groups created on a standard switch and 1 DMZ server virtual machine connected to each port group
  D. The security policy exception set to Reject for the switch to which the two DMZ server virtual machines will be connected
  A. An isolated Private VLAN configured on a distributed switch and the two DMZ server virtual machines connected to the same port group

• Question 490:

  The vSphere administrator needs to migrate a virtual machine from one host to another. The virtual machine .vswp file resides in local storage. Which two techniques can the administrator use to migrate the virtual machine? (Choose two.)

  A. vMotion migration
  B. Cold migration
  C. Storage vMotion migration
  D. Enhanced vMotion migration
  A. vMotion migration
  B. Cold migration
