PSC Disaster Recovery & Business Continuity Flashcards

Which Pure Storage management platform provides centralized visibility into replication lag, RPO health, and DR relationship status across all arrays?

Answer: Pure1 Cloud Management

Pure1 provides a unified cloud-based management plane that displays replication status, RPO graphs, and health alerts for ActiveCluster and ActiveDR relationships across the entire fleet.

What Pure Storage capability allows VMware workloads to migrate non-disruptively between two ActiveCluster sites without VM downtime?

Answer: vSphere vMotion over an ActiveCluster stretched datastore

Because ActiveCluster presents the same datastore (pod) simultaneously at both sites, VMware vMotion can live-migrate VMs between sites with no downtime and no data copy required.

What is the purpose of running a DR drill against a Pure Storage ActiveDR relationship without impacting production data?

Answer: Create a test pod from the DR snapshot without promoting the DR relationship

Pure Storage allows a non-disruptive DR test by cloning the DR pod or creating a volume copy from the replicated snapshot on the target array, leaving the live DR relationship intact.

When planning a Pure Storage business continuity solution, which combination delivers both zero RPO and zero RTO?

Answer: ActiveCluster (synchronous, active-active)

ActiveCluster's active-active, synchronous architecture ensures no data loss (zero RPO) and no recovery time (zero RTO) because both sites serve I/O simultaneously.

What Pure Storage feature ensures that even array administrators cannot delete protected snapshots before their retention period expires?

Answer: SafeMode

SafeMode requires out-of-band verification (via Pure Storage support) before protected snapshots can be deleted, preventing insider or ransomware-driven deletion.

In Pure Storage terminology, what does 'Non-Disruptive Upgrade' (NDU) mean for a two-site ActiveCluster deployment?

Answer: Both sites remain online and serving I/O while Purity is upgraded on each controller sequentially

Pure Storage NDU upgrades each controller sequentially while the partner controller handles I/O, keeping the entire ActiveCluster deployment online and applications running throughout the upgrade.
