A write intensive application has been deployed recently into an All-flash 4-node vSAN cluster. Each node has one disk group with the following configuration:
• 1 x 400 GB SSD for Cache
• 4 x 3.84 TB SSD for Capacity
After the deployment, the administrator notices that the overall workload performance is degraded and observes a low-write, buffer-free percentage.
Which action should be taken to remediate this issue?
An administrator wants to deploy a desktop and application virtualization solution on top of vSAN.
Which VMware product should the administrator install?
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.)
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.)
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?
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.)
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?
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
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?
A customer has upgraded to vSAN 7, but there is still an existing legacy host which must be removed from the vSAN cluster.
Which three steps must an administrator take to successfully remove this host from the vSAN cluster? (Choose three.)
In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?
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?
An administrator is tasked with setting up Kerberos authentication only for the vSAN File services.
Which version of Kerberos must be selected if the NFS version is v4.1?
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?
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?
Which statement accurately describes the result when proper VM Storage Policy Affinity Rules on a stretched vSAN cluster are set?
A cache disk failure marked a vSAN disk group as failed, and the data is being rebuilt on other disk groups.
Which action should the vSAN administrator take to reduce the negative impact on the VMs?

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.)
