An administrator needs to configure an alarm that notifies administrators if an application is impacted by over-commitment of memory resources. The environment consists of 100 virtual machines running on 5 ESXi hosts that are configured in a fully automated HA/DRS cluster. The cluster is configured with a parent resource pool and Production and Development child pools.
Where should the administrator set the alarm to meet the requirement?
A. On each virtual machine
B. On each host
C. On the Production resource pool
D. On the cluster
Correct Answer: D
Explanation/Reference:
Explanation:
D: Given that the cluster is configured with a parent resource pool and production and development child pools, it would be better to configure the alarm on the cluster because it is the cluster that needs to be monitored to see if an application is affected by over-commitment of memory resources.
Incorrect Answers:
A: It is the cluster that should be monitored with the alarms and not the virtual machines.
B: Configuring the alarm on each host would be a lot of administrative effort considering the environment size.
C: The resource pool is on the cluster that should be monitored with appropriate alarm.
