Question 1

After a vSAN Witness Appliance network configuration, the vSAN administrator notices that vSAN traffic flows from vmk0 (Management Traffic) rather than vmk1 (vSAN Traffic).

Which step should be taken to resolve this issue?

AConfigure vmk0 with IP address on the same range as that of vmk1.

BTag the vmk0 for vSAN traffic.

CConfigure vmk1 with IP address on the different network than that of vmk0.

DTag the vmk1 for Witness traffic.

Answer : C

The vmk1 interface cannot be configured with an IP address on the same range as that of vmk0. This is because Management traffic and vSAN traffic use the default TCP/IP stack. If both vmk0 and vmk1 are configured on the same range, a multihoming condition will occur and vSAN traffic will flow from vmk0, rather than vmk1.

Question 2

An administrator has been tasked to reboot a node in an encrypted vSAN cluster. The vSAN disk groups on that node become locked after rebooting the node.

Which step should be performed to exit the locked state?

AManually replace the Host Encryption Key (HEK) of each affected host.

BRestore the communication with the KMS server, and re-establish the trust relationship.

CReplace the caching device in each affected disk group.

DRun /etc/init.d/vsanvpd restart to rescan the VASA providers.

Question 3

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.

What will be the status of the vSAN objects on the affected host immediately after it is recovered?

AThe cluster will be partitioned and the vSAN host will need to be rejoined.

BA rebuild of the affected objects will occur.

CAll objects will remain accessible.

DAll objects on the affected host will be lost.

Answer : C

Default Storage Policy is FTT=1. https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.virtualsan.doc/GUID-C228168F-6807-4C2A-9D74-E584CAF49A2A.html

Question 4

Upon investigating a workload performance issue, a vSAN administrator observed a high backend IOPs on a vSAN cluster.

Which two causes explain this behavior? (Choose two.)

AThe cluster DRS threshold has been set to Aggressive.

BThere is a vSAN node failure.

CThe vSAN Resync throttling is enabled.

DThe object repair timer value has been increased.

EThe vSAN policy protection level has changed from FTT=0 to FTT=1.

Answer : B, E

Question 5

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 6

Which version of Kerberos must be selected if the NFS version is v4.1?

Akrb5i

Bkrb4

Ckrb5

Dkrb5p

Answer : C

Because krb5 for authentication only, or krb5i for authentication and data integrity. https://core.vmware.com/resource/best-practices-running-nfs-vmware-vsphere#sec9459-sub5

Question 7
