問題6

An administrator Is reassessing subnet use in preparation for migrating existing vSAN Clusters to a new subnet.
Which steps should the administrator perform to ensure all VMs remain online during the vSAN network subnet migration?

A. Migrate the VMs using Storage vMotion off the vSAN datastore and rebuild a new vSAN Cluster using the new subnet.

B. Add a second VMkernel port on the new subnet for all hosts and remove original vSAN VMkernel ports.

C. Migrate current vSAN VMkernel ports to a distributed switch and enable vSphere Network I/O Control.

D. Place the hosts Into maintenance mode and update the IP addresses of the current vSAN VMkernel ports to the new subnet.

正確答案: C

問題7

A customer environment includes:
* 4-node vSAN cluster
* 5 SQL servers with an OS virtual disk and database virtual disk
* Current policy uses the vSAN Default Storage policy
A vSAN administrator has created a new policy with fault tolerance method of Erasure Coding with Failures to tolerate equal to 1. The administrator will apply this new policy to the OS disk only.
Considering this scenario, which two statements are true? (Choose two.)

A. This policy will require additional transitional space, until all objects are recreated.

B. The policy will result is size reduction and only will require 1.5x space instead of 2x.

C. The object tree will have to be rebuilt when the policy is applied.

D. The policy can't be applied as there are not enough nodes to comply with the policy.

E. vSAN policies can only be applied to entire VMs.

正確答案: A,C

問題8

B. Data - vSAN Object Health - Healthy

C. Performance Service - Stats DB Object - object health - red

D. Data - vSAN Object Health - Reduced availability with no rebuild
