VCP-VCF Administrator 2024 Question 247
Select 3A VMware Cloud Foundation administrator needs to expand the capacity of a vSAN datastore by adding storage. After ensuring that the vSAN cluster is in a healthy state, what are the correct next steps to add additional capacity?
- A
Add a new ESXi host with local storage to the vSAN cluster.
- B
Add a new disk group to an existing host in the vSAN cluster.
- C
Add an external NFS datastore to the vSAN cluster.
- D
Add flash cache and capacity disks to an existing disk group.
- E
Enable deduplication and compression before adding new storage.
Show answer and explanation
Correct answers: A, B, D
Explanation
To expand a vSAN datastore, an administrator can add new ESXi hosts with local storage, create new disk groups on existing hosts, or add additional disks to existing disk groups. These actions directly contribute to the vSAN cluster's storage capacity. However, adding external storage like NFS datastores is not supported for vSAN, and enabling deduplication and compression is an optimization step rather than a necessary part of adding capacity.
- A. Correct.
Adding a new ESXi host with local storage to the vSAN cluster is a valid way to increase the overall capacity and performance of the vSAN datastore, as it contributes new resources to the cluster.
- B. Correct.
Adding a new disk group to an existing host in the vSAN cluster is a legitimate method for expanding the vSAN datastore's capacity as it allows for additional storage within the cluster.
- C. Incorrect.
Adding an external NFS datastore is not a valid method for adding capacity to a vSAN datastore, as vSAN only supports disks directly managed by the vSAN cluster.
- D. Correct.
Adding flash cache and capacity disks to an existing disk group is a valid method for increasing the storage capacity of the vSAN datastore.
- E. Incorrect.
While enabling deduplication and compression can optimize storage usage, it is not a required step for expanding a vSAN datastore and should not be performed solely to add capacity.
