2V0-21.23 Question 33
Single answerAn administrator is managing a VMware vSphere environment and has created a datastore cluster. The administrator notices that certain virtual machines are not being migrated to less utilized datastores within the cluster, even though other datastores are under heavy usage. What could be the reason for this behavior?
- A
Storage DRS is set to manual mode for the datastore cluster.
- B
The virtual machines have storage policies that restrict datastore placement.
- C
Datastore maintenance mode has been enabled for one of the datastores in the cluster.
- D
The cluster is configured with an insufficient number of datastores to allow migrations.
Show answer and explanation
Correct answer: A
Explanation
When Storage DRS is set to manual mode, it does not automatically migrate virtual machines between datastores within the cluster. Instead, it provides recommendations that must be manually approved by the administrator. This setting is commonly used in production environments where administrators want more control over storage placement decisions.
- A. Correct.
Storage DRS in manual mode means recommendations for migrations are provided, but migrations are not automatically performed. This could explain why virtual machines are not being moved.
- B. Incorrect.
Storage policies can restrict which datastores a virtual machine can be placed on, but this does not directly prevent migrations within a datastore cluster managed by Storage DRS.
- C. Incorrect.
Datastore maintenance mode would cause virtual machines to be evacuated from the datastore, not prevent migrations to less utilized datastores.
- D. Incorrect.
A datastore cluster does not require a specific number of datastores for Storage DRS to function; even with fewer datastores, migrations can occur if needed.
