* The vCenter Server is currently version 7.0.

* The vSAN Cluster has the following configuration:

- vSAN version: 7.0

- Number of vSAN nodes: 6

- CPU: 2 processors, 20 cores

- RAM: 1024GB RAM.

- Disk: 2 Cache SSDs and 6 Capacity SSDs

* 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.)

AUpgrade all vSAN nodes to VMware vSphere 7.0 U1 using the baselines capability within VMware Update Manager (VUM).

BDisable vSAN Encryption before starting the upgrade process.

CUpgrade all vSAN nodes to VMware vSphere 7.0 U1 using the images capability within VMware Update Manager (VUM).

DSet VMware Distributed Resource Scheduling (DRS) to partially automated.

EUpgrade to VMware vCenter Server 7.0 U1.

FChoose the Allow reduced redundancy option.

Question 3

An architect is designing a vSAN cluster.

Which storage controller option will yield optimal performance?

AHugh queue depth

BSet caching to 50% read on the controller

CEnable battery write-back caching

DRAID 0

Correct : A

Storage Controller Queue Depth There are two important items displayed by the VCG for storage I/O controllers that should be noted. The first of these is ''features'' and the second is queue depth. Queue depth is extremely important, as issues have been observed with controllers that have very small queue depths. In particular, controllers with small queue depths (less than 256) can impact virtual machine I/O performance when vSAN is rebuilding components, either due to a failure or when requested to do so when entering maintenance mode. Design Decision : Choose storage I/O controllers that have as large a queue depth as possible. While 256 are the minimum, the recommendation would be to choose a controller with a much larger queue depth where possible. https://core.vmware.com/resource/vmware-vsan-design-guide#sec6843-sub14
