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

    The vCenter Server is currently version 7.0.

    The vSAN Cluster has the following configuration:

    -vSAN version: 7.0

    -Number of vSAN nodes: 6

    -Encryption: enabled

    -Deduplication and Compression: enabled

    -Fault Domains: 1

    -vSAN Capacity Utilization: 60% Each vSAN node has the following configuration:

    -ESXi version: VMware vSphere 7.0

    -CPU: 2 processors, 20 cores

    -RAM: 1024GB RAM.

    -Disk: 2 Cache SSDs and 6 Capacity SSDs

    -Network: 4 x 10GbE All current hardware (which is from a single vendor) is listed on the vSAN Compatibility Guide for vSAN 7.

    Which three recommendations should the consultant make to ensure that the vSAN cluster upgrade is completed? (Choose three.)

    A. Upgrade all vSAN nodes to VMware vSphere 7.0 U1 using the baselines capability within VMware Update Manager (VUM).
    B. Disable vSAN Encryption before starting the upgrade process.
    C. Upgrade all vSAN nodes to VMware vSphere 7.0 U1 using the images capability within VMware Update Manager (VUM).
    D. Set VMware Distributed Resource Scheduling (DRS) to partially automated.
    E. Upgrade to VMware vCenter Server 7.0 U1.
    F. Choose the Allow reduced redundancy option.

  • Question 22:

    In a stretched vSAN cluster, how is Read Locality established after fail over to the secondary site?

    A. 100% of the reads comes from vSAN hosts on the local site
    B. 50% of the reads comes from vSAN hosts on the local site
    C. 100% of the reads comes from vSAN hosts on the remote site
    D. 50% of the reads comes from vSAN hosts on the remote site

  • Question 23:

    A 4-node vSAN cluster is configured with an erasure coding storage policy. The Ensure Accessibility maintenance mode was selected. While performing the maintenance, a second node fails. What will be the impact on the vSAN cluster?

    A. There will be no impact on performance.
    B. The VMs will no longer be accessible.
    C. The performance will be degraded.
    D. The VMs will be in a suspended state.

  • Question 24:

    An administrator is tasked with setting up Kerberos authentication only for the vSAN File services. Which version of Kerberos must be selected if the NFS version is v4.1?

    B. krb4
    C. krb5
    D. krb5p

  • Question 25:

    In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?

    A. SFTT = 0
    B. SFTT = 1
    C. PFTT = 1
    D. PFTT = 0

  • Question 26:

    An architect is working with vSAN and setting the fault domains to support FTT=1. How many fault domains will be needed?

    A. 2
    B. 3
    C. 4
    D. 1

  • Question 27:

    An architect collected the below technical requirements from the customer during a vSAN cluster design workshop:

    Maximize the vSAN datastore usable capacity.

    Deduplication and compression are required to help utilize available capacity efficiency.

    Ensure the highest level of resiliency wherever possible.

    Which disk group configuration should the architect include in the design?

    A. One disk group per host, with one cache tier flash disk and four capacity tier flash disks.
    B. Two disk groups per host, each with one cache tier flash disk and four capacity tier flash disks.
    C. Two disk groups per host, each with one cache tier flash disk and six capacity tier flash disks.
    D. Two disk groups per host, each with one cache tier flash disk and six capacity tier magnetic disks.

  • Question 28:

    A 30-minute power maintenance window has been approved on Sunday. Due to a delay, the maintenance took 20 minutes longer to finish.

    During this time, the vSAN administrator noticed that one of the clusters nodes was affected by a power shortage, as it was connected to an affected power source. The default vSAN storage policy has been applied.
