Question 1

In Pure Storage, what is a 'pod' in the context of ActiveCluster replication?

Accepted Answer

A container object that holds volumes and snapshots that replicate synchronously between arrays

Answer

A pod is a logical container for volumes and snapshots that is stretched across two arrays in ActiveCluster, ensuring all contents replicate synchronously.

Question 2

What Pure Storage feature sends FlashArray snapshots to public cloud storage (AWS, Azure, GCP) for long-term retention?

Accepted Answer

CloudSnap

Answer

CloudSnap replicates FlashArray snapshots to object storage in AWS, Azure, or GCP, enabling offsite, cloud-based data retention.

Question 3

What is the maximum synchronous replication distance typically supported by Pure Storage ActiveCluster?

Accepted Answer

Limited by round-trip latency (generally ≤5 ms RTT)

Answer

ActiveCluster's synchronous replication is constrained by the round-trip latency requirement (typically ≤5 ms), which translates to roughly 50–100 km depending on fiber path.

Question 4

Which CLI command is used to promote a replicated pod to read/write state during a Pure Storage ActiveDR failover?

Accepted Answer

purepod promote

Answer

The 'purepod promote' command promotes a demoted or DR pod on the target array to an active, read/write state during failover.

Question 5

What happens to an ActiveCluster pod automatically when the primary site loses connectivity and the Mediator grants quorum to the secondary site?

Accepted Answer

The pod is promoted at the secondary site and becomes read/write without manual intervention

Answer

When ActiveCluster detects a site failure and the Mediator grants quorum, the surviving site automatically promotes the pod, allowing hosts to continue I/O with no manual steps.
