Best DRS Automation Level for VM Placement
Question
An administrator wants to ensure that when virtual machines (VMs) are powered on, Distributed Resource Scheduler (DRS) places them on the best-suited host.
When the cluster becomes imbalanced, the administrator wants DRS to display recommendations for manual VM migration.
Which DRS automation level should the administrator select? (Choose the best answer.)

The correct answer is B. Partially automated.
Distributed Resource Scheduler (DRS) is a feature in VMware vSphere that dynamically balances resources across hosts in a cluster. DRS can automatically move VMs to different hosts based on resource utilization and other factors to optimize resource utilization and balance workload.
DRS has three automation levels: Fully automated, Partially automated, and Manual.
Fully automated: In this mode, DRS will automatically balance the cluster based on resource utilization and other factors without any user intervention.
Partially automated: In this mode, DRS will automatically balance the cluster based on resource utilization and other factors, but it will also display recommendations for manual VM migrations when the cluster becomes imbalanced.
Manual: In this mode, DRS will not automatically balance the cluster. Instead, it will only display recommendations for manual VM migrations.
Disabled: In this mode, DRS is turned off, and the administrator must manually manage VM placement.
In this scenario, the administrator wants DRS to automatically place VMs on the best-suited host when they are powered on, but also wants to be notified of recommendations for manual VM migrations when the cluster becomes imbalanced. This is why Partially automated is the correct answer.
In Fully automated mode, DRS would automatically balance the cluster without displaying recommendations for manual VM migrations, which is not what the administrator wants.
In Manual mode, DRS would only display recommendations for manual VM migrations and would not automatically balance the cluster, which is also not what the administrator wants.
In Disabled mode, DRS is turned off entirely, which would require the administrator to manually manage VM placement and resource utilization.
Therefore, B. Partially automated is the best answer for this scenario.
