PSC PSC Disaster Recovery & Business Continuity 1 — Questions and Answers
Question 1: What Pure Storage feature enables synchronous replication between two FlashArray systems to achieve zero RPO?
- ActiveCluster (Correct answer)
- ActiveDR
- SafeMode
- CloudSnap
Correct answer: ActiveCluster
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?
- FlashBlade
- Pure1 Cloud
- Mediator (Correct answer)
- ActiveDR Controller
Correct answer: Mediator
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?
- ActiveCluster
- SafeMode
- ActiveDR (Correct answer)
- SnapToCloud
Correct answer: ActiveDR
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?
- ActiveDR
- CloudSnap
- ActiveCluster
- SafeMode (Correct answer)
Correct answer: SafeMode
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?
- 1
- 2 (Correct answer)
- 3
- 4
Correct answer: 2
ActiveCluster requires exactly two FlashArray systems — one at each site — plus a Mediator for quorum.
Question 6: Which Pure Storage replication technology provides the lowest RTO (Recovery Time Objective) in a disaster recovery scenario?
- ActiveDR
- CloudSnap
- Manual snapshot restore
- ActiveCluster (Correct answer)
Correct answer: ActiveCluster
ActiveCluster provides near-zero RTO because both sites are active simultaneously and hosts at the surviving site continue without any failover action.
