Which two requirements must be met before enabling vSphere HA Application Monitoring for a virtual machine? (Choose two.)
A. VMware Tools must be installed on the VM.
B. The vSphere Guest SDK must be installed on the VMs needing Application Monitoring.
C. Application Monitoring requires that vCenter Server is linked to a working instance of vRealize Operations Manager and the End Points Operations agent has been installed on the guest.
D. Application Monitoring is only supported on Linux operating systems.
E. Application Monitoring is only supported on Windows operating systems.
HA Monitoring is available for Linux: https://vdc-download.vmware.com/vmwb-repository/dcr-public/4ac029aa-34ad-46b1-9b60-d2603b426d6e/62af2377-9649-4707-88a7-6e4b3df5376d/vsphere-guest-ha-monitoring-sdk-65-programming-guide.pdf
Thus E is incorrect.

A
When you enable VM Monitoring, the VM Monitoring service (using VMware Tools) evaluates whether each virtual machine in the cluster is running by checking for regular heartbeats and I/O activity from the VMware Tools process running inside the guest.
B
To enable Application Monitoring, you must first obtain the appropriate SDK (or be using an application that supports VMware Application Monitoring) and use it to set up customized heartbeats for the applications you want to monitor. After you have done this, Application Monitoring works much the same way that VM Monitoring does
