Question 1

What Pure Storage feature enables synchronous replication between two FlashArray systems to achieve zero RPO?

Accepted Answer

ActiveCluster

Answer

ActiveCluster provides synchronous, bidirectional replication between two FlashArray systems, delivering zero RPO and transparent failover.

Question 2

In a Pure Storage ActiveCluster deployment, which component serves as a tiebreaker to prevent split-brain scenarios?

Accepted Answer

Mediator

Answer

The Mediator is a lightweight service (hosted on Pure1 or on-premises) that acts as a quorum tiebreaker to prevent split-brain when ActiveCluster sites lose connectivity.

Question 3

Which Pure Storage replication feature provides asynchronous replication with a configurable RPO, typically used for remote DR sites?

Accepted Answer

ActiveDR

Answer

ActiveDR delivers asynchronous replication with configurable RPO (as low as seconds), enabling cost-effective disaster recovery to a remote site.

Question 4

What Pure Storage feature protects snapshot data from ransomware by making snapshots immutable for a configurable retention period?

Accepted Answer

SafeMode

Answer

SafeMode snapshots are protected snapshots that cannot be deleted by array administrators until the retention period expires, providing ransomware protection.

Question 5

What is the minimum number of FlashArray systems required to implement a Pure Storage ActiveCluster stretched cluster?

Accepted Answer

2

Answer

ActiveCluster requires exactly two FlashArray systems — one at each site — plus a Mediator for quorum.
