• Question 74:

  An administrator is attempting to migrate a large Hadoop virtual machine using vMotion. The administrator notices a delay when the machine is quiesced. The Hadoop virtual machine is processing many transactions a second to an in-memory database.

  Which two actions would help reduce the amount of time needed to perform a vMotion on this virtual machine? (Choose two.)

  A. Use multiple NICs for the vMotion vmkernel port.
  B. Use a 10Gbps Network card for the vMotion vmkernel port.

  D. Disable Fault Tolerance before performing the vMotion.
  A. Use multiple NICs for the vMotion vmkernel port.
  B. Use a 10Gbps Network card for the vMotion vmkernel port.

  ---

  Use multiple NICs for the vmotion vmkernel port and a 10 Gbps network card for vMotion vmkernel port. Reference: http://www.yellow-bricks.com/2011/09/17/multiple-nic-vmotion-in-vsphere-5/

• Question 75:

  An administrator reports that the System Event log data is only available for 24 hours when reviewing the Hardware Status tab. Which condition could be responsible for the loss of data?

  A. A Reset event log was executed.
  B. The statistical collection level was set to a value of 1.
  C. The boot disk of the host is corrupt.
  D. Syslog has been configured at the vCenter Server level.
  A. A Reset event log was executed.

  ---

  It clearly shows that the reset event log was executed that's why data is available for 24 hours only.

• Question 76:

  What is true about resource pools created on a Distributed Resource Scheduler (DRS) cluster?

  A. A root resource pool is created with the specified values.
  B. A root resource pool is automatically created using the aggregate total of the ESXi host resources in the cluster.
  C. A root resource pool is automatically created using the aggregate total of all resources in the datacenter.
  D. A root resource pool is not needed when creating resource pools on a DRS cluster.
  B. A root resource pool is automatically created using the aggregate total of the ESXi host resources in the cluster.

  ---

  A root resource pool is automatically created using the aggregate total of the ESXi host resources in the cluster. Reference: https://www.vmware.com/pdf/vmware_drs_wp.pdf

• Question 77:

  An administrator must determine an appropriate backup solution, given these conditions:

  50 of the virtual machines are in a resource pool named Finance.

  50 of the virtual machines are in a resource pool named QA.

  Which solution allows an administrator the ability to backup 100 virtual machines?

  A. Use Snapshot Manager on the vCenter Server to backup the virtual machines.
  B. Use the VMware Consolidated Backup (vcb) tool on the ESXi Host to backup the virtual machines.
  C. Use the VMware Data Recovery (VDR) Appliance on the vCenter Server to backup the virtual machines.
  D. Use the VMware Data Protection (VDP) Appliance on one of the ESXi Hosts to backup the virtual machines.
  D. Use the VMware Data Protection (VDP) Appliance on one of the ESXi Hosts to backup the virtual machines.

  VDP supports these specifications:

  Each vCenter Server can support up to 10 VDP appliances.

  Each VDP appliance supports backup for up to 100 virtual machines.

  Only 1 VDP appliance can exist per ESXi/ESX host.

  Support for 0.5 TB, 1 TB, or 2 TB of deduplicated backup data.

• Question 78:

  Refer to the Exhibit.

  

  An administrator attempts to enable Enhanced vMotion Compatibility (EVC) on a cluster. The operation results in a compatibility error, as shown in the exhibit. What is the likely cause of this error?

  A. The CPUs in the ESXi host are not AMD CPUs.
  B. The CPUs in the ESXi host do not support hardware virtualization capabilities.
  C. The XD/NX CPU features have not been enabled in the BIOS of the server.
  D. There is no shared storage between the hosts in the cluster.
  A. The CPUs in the ESXi host are not AMD CPUs.

  ---

  In general, if a processor can support EVC level XN, it can also support levels XN-1 to X0. For example, a processor that supports the Intel?;Sandy Bridg"; Generation EVC Baseline has an EVC level of L4. Therefore, it can also support EVC

  levels L3, L2, L1, and L0. However, it cannot support EVC level L5, which corresponds to the Intel?;Ivy Bridg"; Generation. Intel EVC Baselines are listed in Table 1.1.

  For AMD processors, there are two different sequences of EVC levels: Levels A0 to A3, which support the first 3 generations of AMD OpteronTM processors, and levels B0 and above, which support AMD OpteronTM Generation 3 and later

  processors.

  Note: The AMD OpteronTM Generation 3 (no 3DNow!TM) EVC baseline is common to both sequences. For example, an AMD processor that supports the AMD OpteronTM Generation 4 EVC baseline supports the AMD OpteronTM

  Generation 3 (no 3DNow!TM) baseline, but not the AMD OpteronTM Generation 3 baseline. An AMD processor that supports the AMD OpteronTM Generation 3 baseline supports the AMD OpteronTM Generation 3 (no 3DNow!TM) baseline,

  but not the AMD OpteronTM Generation 4 baseline.

• Question 79:

  Sales-DB -- Has a memory reservation of 20 GB.

  Sales-DC -- Has a memory reservation of 8 GB.

  Sales-Web -- Has a memory reservation of 8 GB.

  Which statement is correct?

  A. All three virtual machines can power on, but will have memory contention.
  B. All three virtual machines can power on without memory contention.
  C. Only two of the three virtual machines can power on.
  D. Only one of the virtual machines can power on.
  C. Only two of the three virtual machines can power on.

  ---

  As per the scenario, only two of the three virtual machines can power on.

• Question 80:

  C. The vRealize Operations Standard License is in use.
  D. The vmware-rbd-watchdog service failed to start.
  A. The vRealize Operations Foundation License is in use.
