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).

A Software Defined Data Center (SDDC) is a fully virtualized infrastructure where storage, compute, and networking are abstracted and delivered as a service, aligning with the question’s description. It encompasses more than just storage, including processing capabilities.

Option A (Cloud-based Storage):Refers only to storage, not a full facility with processing.

Option B (Virtual Machines):Individual virtualized servers, not a complete facility.

Option D (Data Virtualization):Focuses on abstracting data access, not a full service facility.

EDRP v3 covers SDDC as an advanced virtualization concept for disaster recovery and service delivery (Module: Virtualization and Cloud Computing).

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).
