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 with enabling encryption for existing virtual machines on a vSAN cluster.

Which three prerequisites must be satisfied before completing the task? (Choose three.)

ACreate an encryption storage policy

BEnable Data-In-Transit encryption first

CEnable that the virtual machines are powered on

DVerify if a role with privilege ''Cryptographic operations.Encrypt new'' is assigned

EVerify if a role with privilege ''Cryptographic operations.Migrate'' is assigned

FEstablish a trusted connection with the KMS

Answer : A, D, F

Because Before you can create encrypted virtual machines, you must create an encryption storage policy. You create the storage policy once, and assign it each time you encrypt a virtual machine or virtual disk. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.security.doc/GUID-7DE1ED8F-880B-421E-B27B-5AAA58454AFA.html

Question 3

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 4

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 5

An administrator is planning to deploy workloads on a six node vSAN cluster, and all nodes are distributed equally across three racks.

Which action is required to ensure that the workload VMs remain compliant with the default vSAN policy after a complete rack failure?

AAdd an additional rack with two hosts, and configure vSAN with four fault domains and FTT=1 (erasure coding).

BAdd two additional hosts per rack, and configure vSAN with three fault domains and FTT=1.

CAdd an additional host per rack, and configure vSAN with three fault domains and FTT=2.

DAdd an additional rack with two hosts, and configure vSAN with four fault domains and FTT=1 (mirroring).

Answer : D

Adding an additional rack with two hosts and configuring vSAN with four fault domains and FTT=1 (mirroring) will ensure that the workload VMs remain compliant with the default vSAN policy after a complete rack failure. This is because FTT=1 (mirroring) will provide the highest level of redundancy and ensure that if one rack fails, the other racks can still provide the necessary data to remain compliant.

Question 6

data centers, the customer relayed the following information:

* Highest possible mitigation during a host failure in terms of capacity.

* A constraint in this year's IT budget.

What should the architect recommend?

AEnable operations reserve.
A minimum cluster of 3 vSAN nodes.

BEnable host build reserve.
A minimum cluster of 4 vSAN nodes.

CEnable performance services.
A minimum cluster of 6 vSAN nodes.

DEnable IOInsight Metrics.
A minimum cluster of 2 vSAN ROBO nodes.

Answer : B

Performance services and IOinsight Metrics used for performance analysis. Operation reserve for internal VSAN operations. https://blogs.vmware.com/virtualblocks/2020/09/24/effective-capacity-management-with-vsan-7-update-1/

Question 7

A company hosts a vSAN 7 stretched cluster for all development workloads. The original sizing of a maximum of 250 concurrent workloads in the vSAN cluster is no longer sufficient and needs to increase to at least 500 concurrent workloads within the next six months.

To meet this demand, the original 8-node (4-4-1) cluster has recently been expanded to 16 nodes (8-8-1).

Which three additional steps should the administrator take to support the current growth plans while minimizing the amount of resources required at the witness site? (Choose three.)

AAdd the new vSAN witness appliance to vCenter Server.

BDeploy a new large vSAN witness appliance at the witness site.

CConfigure the vSAN stretched cluster to use the new vSAN witness.

DDeploy a new extra large vSAN witness appliance at the witness site.

EUpgrade the vSAN stretched cluster to vSAN 7.0 U1.

FConfigure the new vSAN witness as a shared witness appliance.
