Question 1

An administrator is setting up vSAN file services on a vSAN cluster but is unable to join the vSAN File Services to the domain.

Which two possible reasons could explain this failure? (Choose two.)

AA read-only domain controller was being used.

BThe administrator did not pre-create a dedicated organizational unit in Active Directory.

CThe administrator wanted to register the file services to a sub-domain.

DThe administrator was using IP addresses from an IP pool.

EThe administrator was using pre-created computer objects for the file services in the Active Directory.

Answer : A, C

Question 2

A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.

The customer currently uses four different vSAN storage policies for running the workloads depending on the applications requirements:

* Policy 1 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Erasure Coding

* Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring

* Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring

* Policy 4 - Site Disaster Tolerance=None - Keep Data on Non-Preferred, FTT=Mirroring

During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:

* Preferred Site - Preferred Site workloads should run on DC1 hosts.

* Secondary Site - Secondary Site workloads should run on DC2 hosts.

Which two activities should the administrator complete to ensure that there is no impact to production services during the maintenance window in the Preferred Site? (Choose two.)

AChange the Site Disaster Tolerance setting in Policy 3 to be ''Dual Site Mirroring''.

BUpdate vSphere DRS site affinity rules so that Preferred Site workloads should not run on hosts in DC1.

CChange the Site Disaster Tolerance setting in Policy 4 to be ''None - Keep Data on Preferred''.

DChange the FTT setting in Policy 3 to be ''Erasure Coding''.

EUpdate vSphere DRS site affinity rules so that Preferred Site workloads must run on hosts in DC2.

Answer : A, E

Question 3

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 4

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 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

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 has engaged a consultant to upgrade an existing vSAN cluster to vSAN 7.0 U1.

During the discovery phase, the consultant found the following information about the existing environment:

* The VMware vCenter Server has recently been upgraded from VMware vSphere 6.7 U3 to version 7.0 U1.

* The vSAN Cluster was recently expanded with identical hardware specification, but from a different hardware vendor.

* The hardware for each vSAN node is listed on the vSAN Compatibility Guide (VCG) for vSAN 7.

* The vSAN Cluster has the following configuration:

- vSAN version: 6.6.1

- Number of vSAN nodes: 10

- Encryption: enabled

- Deduplication and Compression: enabled

- vSAN Capacity Utilization: 60%

* Each vSAN node has the following configuration:

- VMware vSphere ESXi version: 6.5 Update 3

- CPU: 2 processors, 20 cores

- RAM: 768GB RAM.

- Disk: 2 Cache SSDs and 6 Capacity SSDs

- Network: 4 x 10GbE

Which three recommendations should the consultant make to ensure all data remains protected in the event of a vSAN failure? (Choose three.)

AThe Full data migration maintenance mode option must be chosen to protect the data during the upgrade.

BThe Ensure accessibility, migration maintenance mode option must be chosen to protect the data during the upgrade.

CThe upgrade process should be completed using host upgrade baselines in VMware vSphere Lifecycle Manager (vLCM).

DThe vSAN nodes should be upgraded to vSphere ESXi 7.0 U1.

EThe upgrade process should be completed using images in VMware vSphere Lifecycle Manager (vLCM).

FThe vSAN nodes should be upgraded to vSphere ESXi 6.7 U3.

Answer : A, C, D
