An administrator is planning to upgrade from vSAN 6.6 to a newer version. Which is recommended for this upgrade?

• A.Perform a rolling upgrade of the hosts via vSphere Update Manager after upgrading vCenter.
• B.From the command line, turn multicast off in order to migrate to unicast mode.
• C.Certificates used by VASA must be upgraded on vSphere prior to the upgrade.
• D.vSAN VASA Providers must be changed to be internally managed prior to the upgrade.

A vSAN all-flash environment with these host specifications has reported high network latency, write latency, and faces degraded performance:
* One 1Gbps (vSAN, vMotion Traffic)
* One 1Gbps (Management, Fault Tolerance traffic)
Based on the specifications of each host, what is recommended to resolve the issue?

• A.change stripe width to 12
• B.collapse all traffic shared under two 10Gbps NICs
• C.change MTU to 9000
• D.collapse all traffic into one 1Gbps NIC

Which is true about vSAN fault domains?

• A.A vSAN Stretched Cluster has three primary fault domains.
• B.A 2-node vSAN Cluster has two primary fault domains.
• C.A vSAN Standard Cluster cannot be configured with fewer than 3 fault domains.
• D.A vSAN Stretched cluster has two primary fault domains.

Reference the chart.
An IT team is required to size a 4-Node Hybrid vSAN cluster. Four possible configurations have been proposed to meet the requirement of failure to tolerate of one

Each disk group has its own controller.
Which node configuration provides the highest level of resilience?

• A.Option A
• B.Option D
• C.Option C
• D.Option B

An infrastructure architect is designing a vSAN Cluster that must satisfy these requirements:
* support storage policies with 2 failures - RAID-1 (Mirroring)
* support storage policies with 2 failures - RAID-6 (Erasure Coding)
virtual machines must maintain compliance with the storage policy rules above when one host is in maintenance mode with full data migration What is the minimum number of hosts needed to achieve these design requirements?

• A.8
• B.7
• C.5
• D.6
