Autonomous System

PASIS (Pittsburgh Advanced Survivable Information Storage) architecture balances availability, durability, and confidentiality. Increasing availability (easier data access) often reduces confidentiality (data protection) due to trade-offs in access control and encryption strength.
* Option A (Nonrepudiation):Unrelated to availability trade-offs.
* Option B (Durability):Remains high in PASIS, not decreased.
* Option D (Latency):May decrease with higher availability, not increase.
* EDRP v3 discusses PASIS trade-offs, noting confidentiality decreases as availability rises to ensure survivability (Module: Survivable Storage Systems).

Reparability refers to how easily technicians can fix or replace failing components, as described.
* Option B (Recoverability):Ability to restore systems, not repair ease.
* Option C (Robustness):Resilience, not repair-related.
* Option D (Redundancy):Backup components, not repair ease.
* "Reparability measures the ease of resolving or replacing failed components, critical for rapid system restoration" (Module: System Resilience, Section: Maintenance Concepts).

Full Interruption Testing involves shutting down primary systems to test recovery processes, making it expensive (due to downtime costs) and disruptive to normal operations.
* Option B (Simulation Testing):Mimics a disaster without stopping operations.
* Option C (Parallel Testing):Runs recovery systems alongside primary ones, non-disruptive.
* Option D (Checklist Testing):A review process, no operational impact.
* "Full Interruption Testing, while thorough, incurs high costs and disrupts business by halting primary systems to validate recovery" (Module: Testing Disaster Recovery Plans, Section: Test Types).
