Q: 10
A large corporation recently experienced a power outage at one of its primary data centers resulting
in service disruption for customers in that region. An administrator is tasked to assess the current
infrastructure and propose a plan to improve resiliency.
Current configuration:
Single-site vSAN Express Storage Architecture (ESA) cluster
12 hosts
Cluster resource utilization (CPU, memory, and storage) is under 30%
Which solution would improve resiliency and minimize service disruption in data center outages with
a recovery point objective (RPO) of zero without requiring additional hosts?
Options
Discussion
Option A. since stretching the cluster lets you keep RPO at zero without extra hardware. Stretched vSAN works for this scenario.
Does the question mean "best" resiliency, or just any improvement? If the RPO wasn’t strictly zero, then maybe B could work, but with RPO=0 I think A is the only option.
