2V0-21.23 Question 46
Select 3An administrator is managing a vSphere cluster with DRS enabled in fully automated mode. They notice that certain virtual machines are being migrated between hosts more frequently than others. Upon investigation, the administrator learns that the DRS score is influencing these migrations. What factors contribute to the DRS score for a virtual machine?
- A
The CPU and memory demands of the virtual machine
- B
The current workload of the host where the virtual machine is running
- C
The network bandwidth usage of the virtual machine
- D
The configured shares and reservations of the virtual machine
- E
The uptime of the virtual machine
Show answer and explanation
Correct answers: A, B, D
Explanation
The DRS score evaluates a virtual machine’s placement by analyzing its resource demands (CPU and memory), the load on the host, and any configured resource allocations (e.g., shares, reservations). These factors help DRS make decisions about whether to migrate a virtual machine to improve overall cluster efficiency and maintain compliance with resource policies. Network bandwidth usage and uptime are not part of the DRS scoring process.
- A. Correct.
Correct. The CPU and memory demands of the virtual machine are critical for DRS to evaluate its placement and calculate a DRS score.
- B. Correct.
Correct. The current workload of the host plays a key role in determining if the virtual machine should be migrated to balance resources across the cluster.
- C. Incorrect.
Incorrect. DRS does not specifically consider network bandwidth usage when calculating the DRS score for virtual machines.
- D. Correct.
Correct. Resource shares, reservations, and limits configured for the virtual machine are factored into the DRS score to ensure resource allocation policies are adhered to.
- E. Incorrect.
Incorrect. The uptime of the virtual machine is not considered by DRS when calculating the DRS score.
