A Virtual Tape Library (VTL) is a disk-based storage system designed to emulate traditional tape libraries, allowing organizations to use existing tape backup software with faster disk-based storage. It uses HDDs to mimic tape functionality, improving backup and recovery speed.

Option B (Mirroring):Involves duplicating data across drives, not emulating tape.

Option C (Disk-to-Disk):Refers to disk-based backups but not specifically tape emulation.

Option D (Snapshot):A point-in-time copy of data, not a tape-like system.

EDRP v3 covers VTL as a modern backup solution under storage technologies, noting its role in bridging tape and disk systems (Module: Data Backup and Recovery).

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).

A Storage Area Network (SAN) is a dedicated high-speed network that separates storage devices from servers and user networks, providing centralized block-level storage access.

Option A (NAS):Network Attached Storage uses the user network, not a dedicated one.

Option B (SCSI):Small Computer System Interface, a protocol, not a network (likely a typo for SAS).

Option D (SAS):Serial Attached SCSI, a drive interface, not a network.

“SANs provide a dedicated storage network, isolating storage from server and user traffic for efficiency and security” (Module: Storage Technologies, Section: SAN Overview).
