which of the following situations would result in VMware HA NOT restarting virtual machines (Choose Two)?

Assuming the appropriate HA configuration options have been selected, which of the following situations would result in VMware HA NOT restarting virtual machines (Choose Two)?

A.
A guest OS fails

B.
A guest OS is manually powered off

C.
An ESX Server in the cluster becomes isolated from the network

D.
An ESX Server in the cluster is put into Maintenance Mode

Explanation:
A is correct NO PROBLEM, will not restart
B. IF VM MONITORING is configured IT WILL restart (we need to verify is it is enabled by default. If yes, than this is an INCORRECT choice)
C. Incorrect – VMs will be restarted
D. You can put a host in maintenance on HA cluster without DRS, so it will restart. If HOST MONITORING IS disabled – IT WILL NOT RESTART. By default Host Monitoring is enabled which means it may restart.

    I think Answer is A and c AS

    B. guest OS is manually powered off (incorrect because VM monitoring is disabled by default

    D. An ESX Server in the cluster is put into Maintenance Mode (incorrect because Host monitoring is enable so i you put host into maintenance mode its VMs will be restart to another machine

    C. An ESX Server in the cluster becomes isolated from the network
    it is correct as (default Host isolation response is ‘Leave the Power on’)

    The problem here is that it is so vague what the “appropriate HA configuration” is. Most of the scenarios can restart the VM if confured to do so.

    A.
    A guest OS fails – Could go either way, it depends if VM Monitoring is enabled.

    B.
    A guest OS is manually powered off – I need to test this in a lab to see if it does restart with VM Moitoring. Can anyone confirm?

    C.
    An ESX Server in the cluster becomes isolated from the network – THis also depends on how you configured the Host Isolation Response for the individual VM.

    D.
    An ESX Server in the cluster is put into Maintenance Mode – I don’t see any scenarios where HA will restart VMs running on an ESX host that has initiated Maintenance Mode. Are there any?

    It would be something if HA will turn a machine on, when you manually shutdown. How else would you turn it off? Delete it from the inventory? 🙂

  4. Antti says:

    Another stupid question with multiple correct answers.

    I tested answer B in my lab by running “shutdown -hP now” on a linux VM. The VM was powered off and cluster did not restart it, and I had VM monitoring on.
