Full set: 302 questions
Answer options
A: Maximum CPU and memory allowed for the server hosting the Prism Central VM
B: Prism Central cluster mode
C: Prism Central Scale-out deployment Correct answer
D: Large Prism Central VM with the maximum CPU and memory allowed
Correct Answer:
C. Prism Central Scale-out deployment
Explanation

The customer requires both redundancy and the ability to manage 12,500 VMs. A single Prism Central VM, even the "Large" size which supports up to 12,500 VMs, represents a single point of failure and does not provide redundancy. A Prism Central scale-out deployment, which consists of a three-VM cluster, is specifically designed to provide high availability (redundancy) for the management plane. This deployment model also increases the management scale to 25,000 VMs, thereby meeting both of the customer's requirements.

Why Incorrect

A. Maximizing server resources for a single VM provides scale-up but does not add the required redundancy.
B. "Prism Central cluster mode" is a general term; "Scale-out deployment" is the specific and correct name for this configuration.
D. A single Large Prism Central VM meets the VM count but fails to provide the critical redundancy requirement.
