A vSphere administrator needs to reconfigure the Distributed Power Management (DPM) threshold to be more aggressive.
Where should the administrator edit the settings of DPM in the vSphere Web Client?
A. DPM plug-in settings
B. Cluster settings
C. ESXi host power settings
D. vCenter Service Status
Correct Answer: B
Explanation/Reference:
Explanation:
The vSphere Distributed Power Management (DPM) feature allows a DRS cluster to reduce its power consumption by powering hosts on and off based on cluster resource utilization. vSphere DPM monitors the cumulative demand of all virtual machines in the cluster for memory and CPU resources and compares this to the total available resource capacity of all hosts in the cluster. If sufficient excess capacity is found, vSphere DPM places one or more hosts in standby mode and powers them off after migrating their virtual machines to other hosts. Conversely, when capacity is deemed to be inadequate, DRS brings hosts out of standby mode (powers them on) and uses vMotion to migrate virtual machines to them.
The power state (host power on or off) recommendations generated by the vSphere DPM feature are assigned priorities that range from priority-one recommendations to priority-five recommendations.
These priority ratings are based on the amount of over- or under-utilization found in the DRS cluster and the improvement that is expected from the intended host power state change. A priority-one recommendation is mandatory, while a priority-five recommendation brings only slight improvement.
The threshold is configured under Power Management in the cluster’s Settings dialog box. At the Conservative setting, vSphere DPM only generates priority-one recommendations, the next level to the right only priority-two and higher, and so on, down to the Aggressive level which generates priorityfive recommendations and higher (that is, all recommendations.)
Incorrect Answers:
A: The Distributed Power Management (DPM) threshold settings are not configured in the DPM plug-in settings. Therefore, this answer is incorrect.
C: The Distributed Power Management (DPM) threshold settings are not configured in the ESXi host power settings. Therefore, this answer is incorrect.
D: The Distributed Power Management (DPM) threshold settings are not configured in the vCenter Service Status settings. Therefore, this answer is incorrect.
