30TB NFS capacity to mount workload VMs.
What should be the architect\’s recommendations?
A. Point out the risks regarding putting the hosts in maintenance mode in terms of FSVM.
B. Confirm on all of the requirements and move forward with the physical design.
C. Raise concerns regarding support when running VMs on an NFS share as risk.
D. Highlight the required number of nodes required for the vSAN cluster as a constraint.
Correct Answer: D
Question 8:
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. Remove the affected Disk Group from the vSAN Cluster, and choose Full Data Migration.
B. Replace the failed disk with a storage device that is identical in class and capacity.
C. Remove the affected Disk Group from the vSAN Cluster, and choose No Data Migration.
D. Replace the failed disk with a storage device that is identical in class but smaller in capacity.
E. Put the affected vSAN host into maintenance mode to physically replace the storage device.
F. Remove the affected Disk from the Disk Group, and choose Full Data Migration.
Correct Answer: ABF
Question 9:
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?
A. The cluster will be partitioned and the vSAN host will need to be rejoined.
B. A rebuild of the affected objects will occur.
C. All objects will remain accessible.
D. All objects on the affected host will be lost.
Correct Answer: B
Question 10:
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. Configure vmk0 with IP address on the same range as that of vmk1.
B. Tag the vmk0 for vSAN traffic.
C. Configure vmk1 with IP address on the different network than that of vmk0.
D. Tag the vmk1 for Witness traffic.
Correct Answer: A
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 11:
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.)

B. Disconnect from vCenter Server
C. Place the host in maintenance mode with Full Data migration
D. Place the host in maintenance mode with no data migration
E. Remove from vSAN cluster

Question 14:
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.
