Question 1

An architect is designing for a production vSAN cluster, and the customer introduced these requirements related to File Services: A minimum of 12 files shares. 30TB NFS capacity to mount workload VMs.

What should be the architect's recommendations?

APoint out the risks regarding putting the hosts in maintenance mode in terms of FSVM.

BConfirm on all of the requirements and move forward with the physical design.

CRaise concerns regarding support when running VMs on an NFS share as risk.

DHighlight the required number of nodes required for the vSAN cluster as a constraint.

Answer : D

Question 2

A customer is planning to migrate their physical Microsoft SQL Server clustered workloads to vSAN enabled vSphere clusters.

The following requirements must be met:

* Each MSSQL cluster is made up of 3 nodes

* Highest possible availability against node failures

* Some of the vSAN clusters will only consume storage

What should the architect recommend?

AvSAN iSCSI Target Service

BStretched vSAN Cluster

CvSAN Direct

DvSAN File Services

Answer : A

vSAN 6.7 expands the functionality of the vSAN iSCSI Target service to provide the SCSI-3 persistent reservations support for shared disks for windows failover cluster if using the SQL Server FCI, high availability mode is a requirement. The vSAN iSCSI Target service at the vSAN cluster level should be enabled for this purpose. VSAN streched cluster may be used to increase the data availability across data centres. https://blogs.vmware.com/virtualblocks/2019/03/26/considerations-for-running-microsoft-sql-server-workloads-on-vmware-vsan/

Question 3

An administrator would like to upgrade ten identically configured 2-node vSAN clusters from vSAN 6.7 U3 to vSAN 7.0 U1. Currently, each 2-node vSAN cluster is using a dedicated vSAN witness host appliance. As a result of the upgrade, the administrator would like to leverage the vSAN shared witness feature to reduce the resources being consumed.

In preparation for the first vSAN cluster upgrade, the administrator has completed the following tasks:

1. Upgraded vCenter Server to vCenter Server 7.0 U1.

2. vSphere High Availability (HA) has been disabled on the vSAN Cluster.

3. Upgraded the vSAN witness host appliance to vSphere 7.0 U1.

4. Upgraded both vSAN data nodes to vSphere 7.0 U1.

The key requirement is to ensure that backwards compatibility to the existing version of vSAN is maintained during the upgrade process.

Which three additional steps should the administrator complete to ensure that subsequent clusters can share the same vSAN Witness? (Choose three.)

AUpgrade the vSAN On-Disk Format (ODF) to version 12.

BManually update the vSAN Witness with a vSAN 7 license key.

CUpdate the vSAN cluster to use the new vSAN witness host appliance.

DConfigure the existing witness host appliance to act as a shared witness.

EDeploy a new vSAN 7.0 U1 witness host appliance to act as a shared witness.

FUpgrade the vSAN On-Disk Format (ODF) to version 13.

Answer : C, D, F

Question 4

cluster for a customer who is planning to use vRealize Automation to provision 600 virtual machines into that cluster, with expected growth up to 1,000 VM. Each VM has a 40GB thick-provisioned disk.

Which flash disk size is required for the cache tier per ESXi node to meet all requirements?

A400GB

B700GB

C600GB

D800GB

Answer : C

Question 5

An administrator is planning to change a vSAN Storage Policy to apply a Failures To Tolerate (FTT) of 2, using RAID-6.

What is the minimum number of vSAN nodes required?

Answer : A

Question 6

An architect is working with an All-Flash vSAN configuration and will be using the Flash Caching Devices in vSAN.

Which requirement is specifically needed for these devices?

AWrite endurance

BIOPS

CRead endurance

DCapacity

Answer : A

In all-flash configurations, vSAN uses the cache layer for write caching only. The write cache must be able to handle high write activities. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-planning.doc/GUID-1D6AD25A-459A-43D6-8FF5-52475499D6A2.html

Question 7

An administrator managing a vSAN cluster of six-nodes with policy FTT-2/RAID-6 decided to put one of the nodes in maintenance mode using the ''Full-data migration'' option.

What will happen after this action is taken?

AThe host will enter in maintenance mode and the data will remain accessible until the host exits maintenance mode.

BThe system will prompt to add an additional host to the cluster in order to preserve the policy compliance.

CThe host will enter in maintenance mode and only data with no redundancy will remain accessible.

DThe host will enter into maintenance mode if both components of a certain object are residing on that host, then one of the components will be moved to another available host.

Answer : B

https://blogs.vmware.com/virtualblocks/2020/02/06/what-happens-vsan-host-in-maintenance-mode/ Let's take a look at a few unique scenarios with regard to maintenance mode. First, let's see what will happen if you have 6 hosts within your cluster, you have applied a policy containing FTT=2/RAID-6, and you want to place a host in maintenance mode using the 'Full data migration' option. This means all the data residing on the host will be evacuated to another host within the cluster. With this type of data configuration, the system will prompt you to add an additional host to the cluster in order to preserve the policy compliance. The policy will always require there must be two failures that can be tolerated, even during cluster reduction due to maintenance mode removing a host. Note that a minimum of six hosts is required to support a storage policy with RAID-6(FTT=2) erasure coding
