VMware VCP550 Online Questions & Answers

• Question 11:

  A vSphere administrator has created a Virtual SAN Cluster with Automatic Mode Disk Groups. The cluster includes three ESXi hosts contributing one SSD and six SAS disks each. The administrator has four new ESXi hosts that boot from a fiber channel array and have no local disks attached. These four new hosts need additional shared storage but there is insufficient space on the fiber channel array. The hardware budget is limited.

  What can the administrator do to provide the needed storage for the lowest cost?

  A. Add the four new hosts to the Virtual SAN Cluster and use the existing storage in the cluster.
  B. Add an SAS RAID controller to each of the new hosts. Attach one SSD and six SAS disks to each RAID controller and then add the four hosts to the Virtual SAN cluster.
  C. Add the four new hosts to the Virtual SAN Cluster and contribute the fiber channel disks to the Virtual SAN.
  D. Add the four new hosts to the Virtual SAN Cluster and change to Manual Mode Disk Groups.
  A. Add the four new hosts to the Virtual SAN Cluster and use the existing storage in the cluster.

• Question 12:

  Using the vSphere Web Client to display Software iSCSI Initiator properties reveals that one of two configured paths is Not Used.

  The ESXi syslog events are as shown:

  -- Exhibit -

  

  -- Exhibit -What is the root cause of the problem?

  A. The VMkernel adapter named vmk3 is on a subnet different from the iSCSI server's subnet.
  B. The path will only become Active if the VMkernel adapter named vmk1 loses connectivity.
  C. The VMkernel adapter named vmk3 has lost network connectivity.
  D. The VMKernel adapter named vmk3 is on a different vSwitch from vmk1.
  A. The VMkernel adapter named vmk3 is on a subnet different from the iSCSI server's subnet.

• Question 13:

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

• Question 14:

  A vSphere administrator needs to configure a virtual machine to meet a guaranteed CPU performance profile.

  Which configuration setting could the administrator choose?

  A. Set the CPU Limit to High
  B. Set the CPU Shares to 500MHz
  C. Set the CPU Guarantee to High
  D. Set the CPU Reservation to 500MHz
  D. Set the CPU Reservation to 500MHz

• Question 15:

  An ESXi 5.x host disconnects within 60 seconds after the administrator adds it to the vCenter Server inventory. The administrator determines that the issue could be related to a networking problem. Which networking port should the administrator check for connectivity from the host to vCenter Server?

  A. 902
  B. 903
  C. 443
  D. 9443
  A. 902

• Question 16:

  Which two precautions should a vSphere administrator take before increasing the size of a VMFS datastore? (Choose two.)

  A. Unmount the datastore
  B. Perform a rescan to ensure that all hosts see the most current storage
  C. Quiesce I/O on all disks involved
  D. Shut down all virtual machines stored in the datastore
  B. Perform a rescan to ensure that all hosts see the most current storage
  C. Quiesce I/O on all disks involved

• Question 17:

  A VMware administrator determines that a low priority virtual machine is negatively affecting the disk I/O performance of a higher priority virtual machine. The virtual machines are hosted on the same datastore presented to the same ESXi host.

  Which configuration option should the VMware administrator use to resolve this issue?

  A. Increase the disk share value for the high priority VM.
  B. Migrate the low priority VM to another ESXi host.
  C. Create a Storage Profile for each priority level.
  D. Enable vSphere APIs for Array Integration (VAAI).
  A. Increase the disk share value for the high priority VM.

• Question 18:

  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

• Question 19:

  An administrator is deploying a virtual machine from a template.

  Assuming all of the inventory objects below exist in the implementation, what is the highest level in the vCenter Server hierarchy to which a virtual machine can be deployed?

  A. Datacenter
  B. Cluster
  C. Resource Pool
  D. Host
  B. Cluster

• Question 20:

  An administrator decreases the CPU share value for two virtual machines in a DRS cluster from 1000 to 100 shares. The DRS cluster contains more resources than both virtual machines can consume. The characteristics of the virtual machines are listed below:

  The second virtual machine is a clone of the first virtual machine.

  Both virtual machines are identical in every way.

  Both virtual machines are not attached to the IP network.

  Both virtual machines are powered on.

  What impact on the virtual machines' performance will be observed?

  A. The virtual machines will have equal performance under all conditions.
  B. The performance of the virtual machines will reduce by a factor of ten once the share value is adjusted.
  C. The virtual machines will have equal performance under normal conditions and reduced performance when contention occurs.
  D. The original virtual machine will perform better than the clone when contention occurs.
  A. The virtual machines will have equal performance under all conditions.
