VMware 5V0-21.20 Online Questions & Answers

• Question 51:

  A vSAN administrator wants to implement end-to-end prioritization of vSAN traffic across the network in a shared network infrastructure that is using vSphere Distributed Switches (VDS). Which two can help achieve this objective? (Choose two.)

  A. Configure CoS or DSCP with high priority tag at the VDS and equivalent in the physical network.
  B. Enable jumbo frames for vSAN VMkernel ports and configure LACP for optimal load balancing.
  C. Enable Network I/O Control and allocate higher shares for vSAN traffic.
  D. Configure multiple vSAN VMkernel interfaces to load balance across multiple uplinks.
  E. Enable network resource pool at the VDS level to prioritize vSAN traffic.
  B. Enable jumbo frames for vSAN VMkernel ports and configure LACP for optimal load balancing.
  C. Enable Network I/O Control and allocate higher shares for vSAN traffic.

• Question 52:

  A company is using vSAN Data At Rest Encryption. vCenter is placed on a separate management cluster with external storage. The external storage system has suffered from a disk error and the vCenter Server restore from backup has been

  unsuccessful, due to media errors.

  Considering the scenario, which statement is true?

  A. All encrypted disk groups become unmounted and remain offline until vCenter Server is back online.
  B. The data within the vSAN datastore is lost, if the hosts are powered off.
  C. The VMs on the vSAN datastore need to be migrated to another datastore as quickly as possible to prevent data loss.
  D. A new vCenter can be deployed using the existing KMS profile and associated with the existing vSAN encrypted clusters.
  C. The VMs on the vSAN datastore need to be migrated to another datastore as quickly as possible to prevent data loss.

• Question 53:

  A 4-node vSAN cluster has a single disk group per host. An administrator wants to increase the capacity of the vSAN datastore by adding a second disk group to each host in the cluster. The newer drives intended for the second disk group are certified and in compliance with VMware Compatibility Guide (VCG). However, the newer devices procured are of a different make and model than the existing disk group composition.

  Considering the scenario, which statement is true?

  A. This configuration is supported, however performance may vary across disk groups.
  B. The Capacity Tier devices need to be the same make and model as other disk groups.
  C. The Cache Tier devices need to be the same make and model as other disk groups.
  D. This configuration is supported, however a separate controller is mandatory for each disk vendor.
  B. The Capacity Tier devices need to be the same make and model as other disk groups.

• Question 54:

  A 3-node All-Flash vSAN cluster has this configuration:

  One disk group per host All disk groups have identical make and model disks of an 800GB NVMe SSD cache and 2x 4TB SAS SSDs each An administrator has been tasked with expanding storage capacity by adding one additional disk group with this configuration: 1.6TB SAS SSD cache and 1x 4TB SAS SSDs Assuming all the disks are compliant with the vSAN HCL, which is true?

  A. The additional disk group would not be possible as vSAN would not allow it.
  B. The additional disk group would work and be fully supported by VMware support.
  C. The additional disk group will generate an `Advanced vSAN Configuration in sync' health check warning.
  D. The additional disk group would make this cluster an unsupported configuration.
  D. The additional disk group would make this cluster an unsupported configuration.
