A vSphere administrator notices that hosts are not powering off when the total cluster load is low on a cluster configured with Dynamic Power Management.
What condition could cause this behavior?
A. The DRS migration threshold is set to the most conservative setting.
B. The DRS migration threshold is set to the most aggressive setting.
C. The DPM migration threshold is set to the most conservative setting.
D. The DPM migration threshold is set to the most aggressive setting..
Correct Answer: A
Explanation/Reference:
Explanation:
A: The DRS threshold and the vSphere DPM threshold are essentially independent. The DRS migration threshold allows you to specify which recommendations are generated and then applied. You can differentiate the aggressiveness of the migration and host-power-state recommendations they respectively provide. In this case the DRS migration threshold should be adjusted to the most conservative setting to enable the hosts to power off when the cluster load is low.
Incorrect Answers:
B: An aggressive setting in the DRS migration threshold will result in the hosts not powering off.
C: The DPM migration threshold priority ratings are based in the amount of over- or under-utilization found in a DRS cluster and the improvement that is expected from the host power state change. It will result in recommendations. In this case you need to adjust the DRS migration threshold to allow the hosts to power off when the total cluster load is low.
