NEW QUESTION # 30
An administrator of "vsan-prod" cluster noticed the witness components of VMs are flagged as absent after a failed attempt to replace the vSAN Witness Host. Which action should the administrator take to resolve this issue?
- A. Using the RVC command: vsan.resync_dashboard ~/computers/vsan-prod
- B. Upgrading the vSAN on-disk format
- C. Placing the vSAN Witness Host in Maintenance Mode and adding to the vSAN cluster
- D. Running the vSAN Skyline Health check to ensure there are vSAN Object Health errors and executing the Repair Object Immediately option
Answer: D
Explanation:
vSAN Witness Host (so there is strech cluster) must reside in vcenter datacenter container and not be added in vSAN cluster.
NEW QUESTION # 31
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.)
- A. One isolation address reachable only from the witness appliance in both sites
- B. One of isolation addresses should reside in the site 2 data center
- C. One of isolation addresses should reside in the site 1 data center
- D. The default gateway must be used as the only isolation address
- E. VMware vSphere DRS rules to force the VMs to run where the data resides
- F. Host isolation response must exclude the VMs required
Answer: B,C,E
Explanation:
Network Isolation Response and Multiple Isolation Response Addresses
In a Virtual SAN Stretched Cluster, one of the isolation addresses should reside in the site 1 datacenter and the other should reside in the site 2 datacenter. This would enable vSphere HA to validate complete network isolation in the case of a connection failure between sites.

Which statement accurately describes the result when proper VM Storage Policy Affinity Rules on a stretched vSAN cluster are set?
- A. When a site is disconnected, the VM will lose access to its VMDK.
- B. When a site is disconnected, the VM will continue to have access to its VMDK.
- C. Bandwidth is unnecessarily sent across the inter-site link.
- D. Proper policies result in higher inter-site bandwidth utilization.
Answer: B
Explanation:
Setting proper VM/Host Group Rules and VM Storage Policy Affinity Rules are beneficial for several reasons.
Bandwidth is not unnecessarily sent across the inter-site link.
Lower inter-site bandwidth utilization.
In the situation where the alternate site is disconnected, the VM will continue to have access to its vmdk.

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.

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?
- A. Capacity
- B. Read endurance
- C. IOPS
- D. Write endurance
Answer: D
Explanation:
Reference:
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
NEW QUESTION # 40
A failed storage controller has two vSAN disk groups attached. The components contained on the dnves in those disk groups are marked Degraded. vSAN reports that some objects do not comply with their assigned storage policy.
How is the compliance issue resolved?
- A. Degraded components are repaired after CLOM Repair Delay Timer expires.
- B. Initiate a proactive rebalance to force component repairs.
- C. Rebuilding of the degraded components starts immediately.
- D. Storage policies must be reapplied to all affected objects.
Answer: C
NEW QUESTION # 41
An administrator is tasked to create a custom storage policy for workloads and is including additional disk stripes while defining the storage policy.
What is the main purpose of this practice?
- A. To reconstruct corrupted data
- B. To improve performance
- C. To set a failure tolerance
- D. To increase available storage space
Answer: B
Explanation:
https://blogs.vmware.com/virtualblocks/2016/09/19/vsan-stripes/ Striping may help performance if certain virtual machines are I/O intensive and others are not.
The "number of disk stripes per object" storage policy rule attempts to improve performance by distributing data contained in a single object (such as a VMDK) across more capacity devices. https://blogs.vmware.com/virtualblocks/2021/01/21/stripe-width-improvements-in-vsan-7-u1/
NEW QUESTION # 42
In a stretched vSAN cluster, how is Read Locality established after fail over to the secondary site?
- A. 50% of the reads comes from vSAN hosts on the remote site
- B. 50% of the reads comes from vSAN hosts on the local site
- C. 100% of the reads comes from vSAN hosts on the local site
- D. 100% of the reads comes from vSAN hosts on the remote site
Answer: C
Explanation:
vSAN stretched clusters uses a read locality algorithm to read 100% from the data copy on the local site. Read locality reduces the latency incurred during reading operations.

- A. All objects will remain accessible.
- B. All objects on the affected host will be lost.
- C. The cluster will be partitioned and the vSAN host will need to be rejoined.
- D. A rebuild of the affected objects will occur.
Answer: A
Explanation:
The 60 Minutes Delay timer had not expired, the status of the objects will be NON complaint but will be accessible.
NEW QUESTION # 44
