VMware 5V0-21.20 Online Questions & Answers

  • Question 21:

    Reference the exhibit.

    A university campus has a site topology illustrated in the exhibit. Adjacent connected buildings are connected with a single 40gb layer 3 network with a RTT of 0.6ms as depicted by each line. An architect wants to configure a fault domain in each building.

    What would the architect need change in order to implement a fully supported vSAN Cluster?

    A. Enable a single Layer 2 network across all buildings for vSAN connectivity.
    B. Decrease the existing RTT between the existing links by 0.1ms or more.
    C. Add an additional link to the existing adjacent links to make it redundant.
    D. Enable IPv6 networks across all buildings for vSAN connectivity.

  • Question 22:

    During planned maintenance of a four-node vSAN cluster, an outsourced IT contractor accidentally removed a 2.5" SSD cache disk from one of the vSAN nodes. The storage policy has been configured with FTT=1 RAID 1, and the disk management UI marked the disk group as absent.

    Which remediation steps should the administrator select to ensure VMs become compliant with the storage policy as soon as possible?

    A. replace the SSD cache disk > rescan > add disk back in disk group
    B. enter host in maintenance > remove from disk group > shutdown host > replace disk > power on host
    C. remove disk group > enter host in maintenance > fully evacuate all data > exit maintenance
    D. vSAN Health Check > retest > object health > repair objects immediately

  • Question 23:

    Three months ago, an administrator deployed vRealize Operations Manager from vCenter to manage his newly deployed four-node vSAN 6.7 All-Flash cluster. What must the administrator do to continue using vRealize Operations Dashboards for vSAN?

    A. Reconfigure the vSAN cluster.
    B. Upgrade vRealize Operation Manager.
    C. Apply the correct license to the vSAN cluster.
    D. Reconfigure the vRealize Operations Manager.

  • Question 24:

    Which two statements regarding networking are true for a vSAN Stretched Cluster? (Choose two.)

    A. A 5ms RTT or less is required between the data sites.
    B. The vSAN data network must communicate with the vSAN witness host.
    C. PIM is required for stretched vSAN clusters.
    D. A Stretched Cluster can use Layer 2 or Layer 3 communication for the vSAN network.
    E. A Stretched Layer 2 network is required at the vSAN data sites and at the witness site.

  • Question 25:

    The clomd service has stopped on 1 host in a 3-node vSAN cluster. All other services on the host, as well as the other 2, are healthy. Additionally, the unmodified vSAN Default Storage Policy is in use. Which would be an expected outcome for a new VM deployed into the vSAN cluster?

    A. VM deployment will fail.
    B. VM deployment will complete but VM IO will fail.
    C. VM deployment will complete but performance will be degraded.
    D. VM deployment will be deferred by vCenter.

  • Question 26:

    An administrator receives an alert for vCenter being unavailable. With vCenter running on vSAN, the administrator wants to know if any other VMs are impacted. What command can an administrator run to determine the overall health of the vSAN objects?

    A. esxcli vsan storage list
    B. esxcli vsan cmmds timemachine get
    C. esxcli vsan cluster get
    D. esxcli vsan health cluster list

  • Question 27:

    Which Kubernetes component must be configured to allow for dynamics provisioning of container volumes on vSAN?

    A. vSphere Container Storage Interface driver
    B. vSphere Cloud Storage Plugin
    C. glusterfs
    D. Cinder

  • Question 28:

    Which three should be taken into consideration when configuring a Stretched Cluster? (Choose three.)

    A. bandwidth between sites
    B. geographical distance
    C. number of objects
    D. vSphere version
    E. latency between sites

  • Question 29:

    What are two factors to consider prior to placing a vSAN node into Maintenance Mode with full data migration? (Choose two.)

    A. vSAN node must be removed from the cluster.
    B. vSAN must be disabled from command line on the host.
    C. Number of fault domains required to satisfy storage policies.
    D. Sufficient vSAN free storage capacity must exist.
    E. VMs registered to the host must be powered off.

  • Question 30:

    An architect has been asked to plan the impact of a storage policy change to one of the production All-Flash based vSAN datastores. The change will reduce the failures to tolerate value from 2 to 1 for objects with a RAID-1 (Mirroring) layout in the existing policy. This change will be applied to multiple VMs.

    Which statement is correct in this scenario?

    A. FTT-2 requires another change to apply a RAID-6 configuration.
    B. The policy will need to be recreated and applied with an additional tag.
    C. There will be no objects rebuilt that impact performance.
    D. There will be an object rebuild impact on performance.
