1. An organization has two vSAN clusters managed by the same vCenter Server, each providing 100TB of storage. The first cluster runs at 75% of its storage capacity, and the second cluster runs at 50% of its storage capacity.

The company also has the following:

* An iSCSI array of 300TB. which runs at 76% of its capacity

* A NAS system of 200TB, which runs at 10% of its capacity

* A Fiber channel (FC) array of 300TB, which runs at 80% of its capacity

The administrator is asked to add an additional 25TB of storage to the first cluster. The administrator is also made aware that there is no budget to purchase new hardware and that the vSAN Storage Policy Based Management must be kept in place.

Which storage option will work for this use case?

Create an HCI Mesh using the first cluster’s datastore.

Obtain additional free capacity from the existing NAS storage.

Obtain additional free capacity from the existing FC storage.

Create an HCI Mesh using the second cluster’s datastore.

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?

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

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

Replace the caching device in each affected disk group.

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

3. 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?

Point out the risks regarding putting the hosts in maintenance mode in terms of FSV

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

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

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

4. During a design workshop for a stretched vSAN cluster, the requirement that some of the VMs be configured with no-mirror between sites was discussed.

Which three recommendations should the architect provide to address an event of a network partition between two sites? (Choose three.)

Host isolation response must exclude the VMs required

The default gateway must be used as the only isolation address

One of isolation addresses should reside in the site 1 data center

VMware vSphere DRS rules to force the VMs to run where the data resides

One isolation address reachable only from the witness appliance in both sites

One of isolation addresses should reside in the site 2 data center

5. An administrator wants to enable encryption on an existing vSAN cluster that already contains virtual machines.

Which additional step should the administrator take to ensure no data is lost during the encryption process?

Select ‘Erase disks before use’ check box when enabling encryption on a vSAN cluster.

Make vCenter Server trust the KMS, either by trusting the KMS or by uploading a KMS certificate.

Ensure that the vSAN Encryption is enabled by default on the existing cluster to encrypt old and new data.

Disable vSphere Distributed Resources Schedule (DRS) on the vSAN cluster.

6. An 8-Node vSAN Stretched Cluster (4+4+1) with a single disk group has a policy with PFTT=1 (mirrored across sites) and SFTT=1/FTM Mirroring (Local Protection) configured.

The administrator has been alerted that there is a problem with the cluster.

The following has been observed:

* The vSAN Witness Host is offline.

* Two disk failures on two hosts have occurred in the preferred site.

This has resulted in a critical production virtual machine’s vmdk becoming inaccessible.

Which step needs to be performed by the administrator to resolve the issue?

Replace all failed disks on the preferred site.

Replace the vSAN Witness Host

Replace access to the existing vSAN Witness Host

Replace only one failed disk on the preferred site.

7. An architect needs to automate an infrastructure that supports VMware Horizon as well as VMware Tanzu.

Which solution mandates the use of VMware vSAN?

VMware Cloud Foundation

VMware Horizon

VMware Tanzu

VMware vRealize Automation

8. An architect is designing a vSAN cluster.

Which storage controller option will yield optimal performance?

Hugh queue depth

Set caching to 50% read on the controller

Enable battery write-back caching

RAID 0

9. An administrator wants to check the performance metrics for the workloads and their virtual disks that are running on a vSAN cluster, but no statistical charts are displayed in the vSphere client.

Why is this behavior being seen?

vSAN network diagnostic mode is not enabled.

vSAN proactive tests haven’t been run yet.

vSAN performance service is turned off.

vSAN performance verbose mode is not enabled.

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

400GB

700GB

600GB

800GB

11. 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.)

Create an encryption storage policy

Enable Data-In-Transit encryption first

Enable that the virtual machines are powered on

Verify if a role with privilege “Cryptographic operations.Encrypt new” is assigned

Verify if a role with privilege “Cryptographic operations.Migrate” is assigned

Establish a trusted connection with the KMS

12. During a vSAN design workshop, an architect collected these customer requirements:

* Leverage vSAN storage policies with Erasure Coding.

* Enable Deduplication and Compression.

* Use the minimum number of hosts in the cluster.

* Maintain full storage policy compliance when two nodes are down .

Which vSAN cluster design meets the customer’s requirements?

Five nodes All-Flash vSAN cluster

Six nodes All-Flash vSAN cluster

Six nodes Hybrid vSAN cluster

Five nodes Hybrid vSAN cluster

13. Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster.

The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs.

The current vSAN cluster has the following configuration:

* 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM

* 1 Disk Group per vSAN node

- 1 x 400 GB

- 4 x 1.8 TB

* De-duplication and Compression is enabled.

* vSAN Capacity is currently:

- Total: 72 TB

- Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5).

As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased.

Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)

Install an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.

Update the existing Disk Group, and claim the newly installed drives for each node.

Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.

Install an additional 3 x 1.8 TB SSDs per vSAN node.

Replace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.
