An administrator wants to monitor virtual machines on a host and send notifications when memory usage reaches 80%. What should the administrator create in vCenter Server to accomplish this?

The correct answer is B. A vCenter Server alarm that will monitor virtual machine memory usage and set an action to email. vCenter Server alarms monitor inventory objects like VMs and can execute actions such as sending email notifications when a defined metric threshold is met.

Why each option

vCenter Server alarms monitor inventory objects like VMs and can execute actions such as sending email notifications when a defined metric threshold is met.

AA host alarm that will monitor virtual machine memory usage and set a trigger to email the

There is no distinct 'host alarm' object type in vCenter; alarms are vCenter Server objects, and the term 'trigger' does not describe the notification step - that step is called an 'action'.

BA vCenter Server alarm that will monitor virtual machine memory usage and set an action to emailCorrect

A vCenter Server alarm is the correct construct for monitoring VM metrics across a host - it is configured with a trigger condition (memory usage at 80%) and an alarm action such as 'Send a notification email', which is the correct vSphere terminology for the response step.

CA host alarm that will monitor virtual machine memory usage and set an action to email the

Host alarms are not a separate alarm category in vCenter Server, making this the wrong object type even though 'action' is the correct term for the email step.

DA vCenter Server alarm that will monitor virtual machine memory usage and set a trigger to email

While 'vCenter Server alarm' is the correct object, using 'trigger' to describe the email notification step is incorrect - 'trigger' refers to the condition definition, whereas 'action' is the correct term for sending email.
