What could indicate that an Availability Zone is not accessible as per the protection policy?

1. NearSync replication between the Availability Zones has fallen out of scope

2. Workloads are no longer within their intended RPO

3. There is a scheduled outage for the Availability Zone

4. Prism Central in the Availability Zone is unavailable

The correct answer is: There is a scheduled outage for the Availability Zone

The situation described in the question highlights the significance of scheduled outages in relation to the accessibility of an Availability Zone. When there is a scheduled outage for an Availability Zone, it means that the resources within that zone are intentionally taken offline or are undergoing maintenance. This directly impacts the availability of services and workloads that depend on that zone. Therefore, if a scheduled outage is in effect, it signifies that the Availability Zone is not accessible, consistent with the protection policy's expectations for maintaining workload availability. In this context, the other scenarios, while they may indicate issues in their own right, do not necessarily confirm that an Availability Zone is inaccessible. For instance, a situation where NearSync replication has fallen out of scope might highlight a potential configuration or performance issue, but it does not mean the zone itself is currently inaccessible. Likewise, workloads being outside their intended RPO (Recovery Point Objective) suggests that there may be data protection concerns, but it does not provide definitive evidence that the zone is unreachable. Lastly, while Prism Central being unavailable indicates a management issue, it doesn't inherently mean that the zone itself is inaccessible from a resource perspective, as the actual workloads could still be running. Therefore, a scheduled outage is the clearest indicator that accessibility is compromised.
