Durability in PASIS (Pittsburgh Advanced Survivable Information Storage) ensures data remains recoverable despite node failures, using redundancy and encoding, enabling James to retrieve data post-earthquake.

Option B (Availability):Ensures access, not recovery after loss.

Option C (Reaction):Not a PASIS feature.

Option D (Integrity):Ensures data accuracy, not recovery.

“Durability in PASIS architecture guarantees data recovery from failed nodes through redundancy and encoding, enhancing survivability” (Module: Survivable Storage Systems, Section: PASIS Features).

Recovery Point Objective (RPO) measures the data loss window, here 13 hours from the last backup (8:00 pm) to the disaster (9:00 am), not recovery time (8 hours). The ‘minus 13 hours’ phrasing is misleading; RPO is the correct term for potential data loss.

Option A (RTO):Time to restore (8 hours), not data loss.

Option B (MAO):Maximum downtime tolerance, not data-specific.

Option D (SPOF):A failure point, unrelated to time.

“RPO defines the time between the last backup and a disaster, indicating potential data loss, critical for planning” (Module: Recovery Metrics, Section: RPO Definition).

Backup Integrity Testing is the process of verifying that backed-up data remains safe, secure, andreadable after operations such as updates, restores, or retrievals. This involves checking for corruption, ensuring data consistency, and confirming that the backup can be successfully restored. In disaster recovery, this is a critical step to ensure that backups are reliable when needed.

Option A (Database Authentication):Refers to verifying user access, not data integrity.

Option B (Database Consolidation):Involves merging databases, not testing backup integrity.

Option C (Database Integrity Testing):Focuses on database consistency, not specifically backup verification.

“Backup Integrity Testing ensures that data backups remain uncorrupted and usable post-operation. This process includes validation checks after updates or restores to guarantee recoverability, a key component of data protection strategies” (Module: Data Backup and Recovery, Section: Backup Validation Techniques).
