What is not a supported method for increasing the availability of a vCenter Server virtual machine?
A. vSphere High Availability
B. vSphere Fault Tolerance
C. vCenter Server Heartbeat
D. Site Recovery Manager
Correct Answer: B
Explanation/Reference:
Explanation:
You can virtualize a vCenter Server to utilize the manageability and recovery capabilities of vSphere.
Fault Tolerance (FT) enables the recovery of a VM with virtually no downtime. It does this by maintaining a running secondary VM on another host and using Lockstep technology to keep the secondary VM in sync with the primary VM.
A vCenter Server requires a server or VM with a minimum of two CPUs.
However, Fault Tolerance (FT) is only supported on VMs with a single CPU. Therefore, we cannot use FT on a VM configured as a vCenter Server.
Incorrect Answers:
A: vSphere High Availability (HA) will, in the event of a failure, restart the failed VM on another host in a cluster. vSphere High Availability (HA) can be used to increase the availability of a vCenter Server virtual machine. Therefore, this answer is incorrect.
C: VMware vCenter Server Heartbeat is used to provide high availability for VMware vCenter Server in case of hardware, network, application, and OS failure. It does this by using an active server and a passive server. VMware Server Heartbeat can be used to increase the availability of a vCenter Server virtual machine. Therefore, this answer is incorrect.
D: vSphere Site Recovery Manager (SRM) is a disaster recovery management product from VMware that provides automated failover between primary and backup datacenters. SRM can be used to increase the availability of a vCenter Server virtual machine. Therefore, this answer is incorrect.
