Question
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
- ARelocate six ESX hosts to another data center and configure a vSAN Stretched Cluster.
- BDeploy VMware Live Recovery to maintain an identical copy in a secondary site.
- CConvert existing production workload to a 2 failures ?RAID-1 storage policy.
- DConfigure the twelve ESX hosts into six fault domains.

Explanation
The VCF 9.0 Design Guide highlights that for resiliency across sites with RPO = 0, the recommended approach is a vSAN Stretched Cluster. Documentation states: "Stretched clusters provide site-level resilience by mirroring data across two fault domains (sites). In the event of a full site outage, workloads remain available with no data loss (RPO = 0)." Relocating six hosts to another site creates the two fault domains required for vSAN Stretched Cluster.
