Question 1

An administrator is setting up vSAN file services on a vSAN cluster.

Which two security policies on the distributed port groups are automatically enabled in the process? (Choose two.)

AForged Transmits

BPromiscuous Mode

CDVFiltering

DJumbo Frames

EMacLearning

Answer : A, E

https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan.doc/GUID-CA9CF043-9434-454E-86E7-DCA9AD9B0C09.html MacLearning and Forged Transmits are enabled as part of the vSAN File Services enablement process for a provided DVS port group.

Question 2

An administrator has received an alert indicating that a single capacity device is close to failing within the production vSAN Cluster. The administrator must now complete preemptive maintenance on the vSAN Cluster without impacting the availability of workloads or vSAN File Services.

The following information is known about the vSAN Cluster:

* vSAN 7.x Cluster

* vSAN node count: 8

* De-Duplication and Compression: Enabled.

* Encryption: Disabled

* Current Utilization: 45%

* Disk Groups: 2

* Devices per node: 2 x 400 GB SSD, 6 x 1.8 TB SSD

Which three steps should the administrator take to successfully complete the task? (Choose three.)

ARemove the affected Disk Group from the vSAN Cluster, and choose Full Data Migration.

BReplace the failed disk with a storage device that is identical in class and capacity.

CRemove the affected Disk Group from the vSAN Cluster, and choose No Data Migration.

DReplace the failed disk with a storage device that is identical in class but smaller in capacity.

EPut the affected vSAN host into maintenance mode to physically replace the storage device.

FRemove the affected Disk from the Disk Group, and choose Full Data Migration.

Answer : B, E, F

If you upgrade the capacity device, verify the following requirements:

- Verify that the cluster contains enough space to migrate the data from the capacity device.

- Place the host in maintenance mode. See Place a Member of Virtual SAN Cluster in Maintenance Mode.

'Select the flash capacity device or magnetic disk, and click Remove selected disk(s) from disk group.'

Question 3

Upon checking the latency goal under vSAN performance diagnostics, the vSAN Administrator sees this message displayed:

The increase in latency in the vSAN stack might be beyond expected limits.

Which two root causes can be identified to help remediate the issue? (Choose two.)

AvSAN VMKemel portgroup is configured with the ''Route based on IP hash'' teaming policy

BvSAN encryption is enabled

CLarge packet losses and retransmissions on the network layer

DIncorrect sizing of the disk groups capacity disks

EOne or more disk groups are congested

Answer : C, E

Question 4

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 5

An administrator is planning to deploy cloud-native workloads onto the vSAN Direct datastore.

Which storage policy structure rule is supported?

AHost-based rules

BvVOL storage rules

CTag-based placement rules

DStorage performance-based rules

Answer : C

Question 6

During a maintenance action on a vSAN node, a vSAN administrator noticed that the default repair delay time is about to be reached.

Which two commands must be run to extend the time? (Choose two.)

A/etc/init.d/vsanmgmtd restart

Besxcli system settings advanced set -o /VSAN/ClomRepairDelay -i 50

Cesxcli system settings advanced set -o /VSAN/ClomRepairDelay -i 80

D/etc/init.d/clomd restart

E/etc/init.d/vsanobserver restart

Answer : C, D

Question 7

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

A100% of the reads comes from vSAN hosts on the local site

B50% of the reads comes from vSAN hosts on the local site

C100% of the reads comes from vSAN hosts on the remote site

D50% of the reads comes from vSAN hosts on the remote site

Answer : C

In the event of a failure or maintenance event, the virtual machine is restarted on the remote site. The 100% rule continues in the event of a failure. This means that the virtual machine will now read from the replica on the site to which it has failed over. One consideration is that there is no cached data on this site, so cache will need to warm for the virtual machine to achieve its previous levels of performance.
