312-76 Exam Dumps : EC-Council Disaster Recovery Professional v3 (EDRP)

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).

Scalability refers to a system’s ability to handle increased demand by adding resources, such as Joan’s addition of virtual memory to accommodate traffic spikes and reduce delays.

Option A (Transparency):Hides system complexity, not resource expansion.

Option B (Openness):Relates to system accessibility, not capacity.

Option D (Monotonicity):A mathematical property, irrelevant here.

“Scalability enhances system performance by adding resources like memory or nodes to manage increased loads, critical for maintaining service levels” (Module: System Resilience, Section: Scalability Concepts).

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).
