VMware 5V0-21.21 Online Questions & Answers

  • Question 1:

    An architect needs to automate an infrastructure that supports VMware Horizon as well as VMware Tanzu. Which solution mandates the use of VMware vSAN?

    A. VMware Cloud Foundation
    B. VMware Horizon
    C. VMware Tanzu
    D. VMware vRealize Automation

  • Question 2:

    An architect is tasked to design a VMware Horizon Solution with vSAN. The architect needs to use a solution to host the user's profile shares in a highly available manner, and it must be guest OS independent. Which solution will match these requirements?

    A. Cluster out of the box
    B. Cluster in a box
    C. NFS on vSAN
    D. iSCSI on vSAN

  • Question 3:

    An administrator is tasked with preparing for a Cross vCenter migration in a stretched vSAN cluster where the virtual machines migration will be orchestrated via VMware Site Recovery Manager. Which action should the administrator take so the migration is successful?

    A. Disable vSAN Deduplication and Compression
    B. Reconfigure vCenter HA Admission control
    C. Enable vCenter Single Sign-On Enhanced Linked Mode
    D. Make sure that Witness traffic is on the management NIC.

  • Question 4:

    A company hosts a vSAN 7 stretched cluster for all development workloads. The original sizing of a maximum of 250 concurrent workloads in the vSAN cluster is no longer sufficient and needs to increase to at least 500 concurrent workloads

    within the next six months.

    To meet this demand, the original 8-node (4-4-1) cluster has recently been expanded to 16 nodes (8-8-1).

    Which three additional steps should the administrator take to support the current growth plans while minimizing the amount of resources required at the witness site? (Choose three.)

    A. Add the new vSAN witness appliance to vCenter Server.
    B. Deploy a new large vSAN witness appliance at the witness site.
    C. Configure the vSAN stretched cluster to use the new vSAN witness.
    D. Deploy a new extra large vSAN witness appliance at the witness site.
    E. Upgrade the vSAN stretched cluster to vSAN 7.0 U1.
    F. Configure the new vSAN witness as a shared witness appliance.

  • Question 5:

    An administrator of “vsan-prod” cluster noticed the witness components of VMs are flagged as absent after a failed attempt to replace the vSAN Witness Host. Which action should the administrator take to resolve this issue?

    A. Upgrading the vSAN on-disk format
    B. Running the vSAN Skyline Health check to ensure there are vSAN Object Health errors and executing the Repair Object Immediately option
    C. Using the RVC command: vsan.resync_dashboard ~/computers/vsan-prod
    D. Placing the vSAN Witness Host in Maintenance Mode and adding to the vSAN cluster

  • Question 6:

    A company has engaged a consultant to upgrade an existing vSAN cluster to vSAN 7.0 U1.

    During the discovery phase, the consultant found the following information about the existing environment:

    The VMware vCenter Server has recently been upgraded from VMware vSphere 6.7 U3 to version 7.0 U1.

    The vSAN Cluster was recently expanded with identical hardware specification, but from a different hardware vendor.

    The hardware for each vSAN node is listed on the vSAN Compatibility Guide (VCG) for vSAN 7.

    The vSAN Cluster has the following configuration:

    -vSAN version: 6.6.1

    -Number of vSAN nodes: 10

    -Encryption: enabled

    -Deduplication and Compression: enabled

    -vSAN Capacity Utilization: 60%

    Each vSAN node has the following configuration:

    -VMware vSphere ESXi version: 6.5 Update 3

    -CPU: 2 processors, 20 cores

    -RAM: 768GB RAM.

    -Disk: 2 Cache SSDs and 6 Capacity SSDs

    -Network: 4 x 10GbE

    Which three recommendations should the consultant make to ensure all data remains protected in the event of a vSAN failure? (Choose three.)

    A. The Full data migration maintenance mode option must be chosen to protect the data during the upgrade.
    B. The Ensure accessibility, migration maintenance mode option must be chosen to protect the data during the upgrade.
    C. The upgrade process should be completed using host upgrade baselines in VMware vSphere Lifecycle Manager (vLCM).
    D. The vSAN nodes should be upgraded to vSphere ESXi 7.0 U1.
    E. The upgrade process should be completed using images in VMware vSphere Lifecycle Manager (vLCM).
    F. The vSAN nodes should be upgraded to vSphere ESXi 6.7 U3.

  • Question 7:

    A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.

    The customer currently uses four different vSAN storage policies for running the workloads depending on the applications requirements:

    Policy 1 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Erasure Coding

    Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring Policy 4 - Site Disaster Tolerance=None - Keep Data on Non-Preferred, FTT=Mirroring

    During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:

    Preferred Site - Preferred Site workloads should run on DC1 hosts.

    Secondary Site - Secondary Site workloads should run on DC2 hosts.

    Which two activities should the administrator complete to ensure that there is no impact to production services during the maintenance window in the Preferred Site? (Choose two.)

    A. Change the Site Disaster Tolerance setting in Policy 3 to be “Dual Site Mirroring”.
    B. Update vSphere DRS site affinity rules so that Preferred Site workloads should not run on hosts in DC1.
    C. Change the Site Disaster Tolerance setting in Policy 4 to be “None - Keep Data on Preferred”.
    D. Change the FTT setting in Policy 3 to be “Erasure Coding”.
    E. Update vSphere DRS site affinity rules so that Preferred Site workloads must run on hosts in DC2.

  • Question 8:

    An administrator is planning to deploy cloud-native workloads onto the vSAN Direct datastore. Which storage policy structure rule is supported?

    A. Host-based rules
    B. vVOL storage rules
    C. Tag-based placement rules
    D. Storage performance-based rules

  • Question 9:

    An administrator wants to enable encryption on an existing vSAN cluster that already contains virtual machines. Which additional step should the administrator take to ensure no data is lost during the encryption process?

    A. Select ‘Erase disks before use’ check box when enabling encryption on a vSAN cluster.
    B. Make vCenter Server trust the KMS, either by trusting the KMS or by uploading a KMS certificate.
    C. Ensure that the vSAN Encryption is enabled by default on the existing cluster to encrypt old and new data.
    D. Disable vSphere Distributed Resources Schedule (DRS) on the vSAN cluster.

  • Question 10:

    An administrator is tasked with sharing storage from one vSAN cluster to another vSAN cluster. SPBM management must be preserved end-to-end, and the policy must be applied by the source vSAN cluster which is storing the data. Both vSAN clusters are managed by the same vCenter server.

    What should the administrator configure?

    A. NFS volumes on vSAN
    B. iSCSI targets on vSAN
    C. HCI Mesh on vSAN
    D. vVOLs on vSAN
