Three-tier architecture in decentralized computing consists of Client (presentation), Application Server (logic), and Database Server (data), as standard layers.

Option A/B/C:Include unrelated or incorrect terms (e.g., Peer-to-Peer).

“Three-tier architecture comprises Client, Application Server, and Database Server, decentralizing functions for scalability” (Module: Network Architectures, Section: Tiered Architectures).

Disaster Recovery (DR) encompasses restoring data, applications, and infrastructure post-disaster, ensuring business operations resume, aligning with the question’s broad scope.

Option A (Data Recovery):Limited to data, not applications or infrastructure.

Option C (Application Recovery):Focuses only on applications.

Option D (Recovery Management):A process, not the ability itself.

“Disaster Recovery restores data, applications, and infrastructure after a disaster, enabling business continuity” (Module: Disaster Recovery Planning, Section: DR Definition).

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).
