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

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).

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).

High Availability (HA) ensures continuous operation by automatically switching to backup components (like virtual memory) during a failure, minimizing downtime, as in ABC Inc.’s case.

Option A (Deduplication):Removes redundant data, not a failover feature.

Option C (Fault Tolerance):Prevents failure impact but typically implies no interruption, not a switch.

Option D (Mirroring):Duplicates data, a component of HA, but not the full feature.

“High Availability maintains operations through automatic failover to backup resources, ensuring business continuity during component failures” (Module: System Resilience, Section: Availability Features).
