A Mobile Recovery Center is a portable, transportable unit that can be deployed anywhere as a temporary operating environment post-disaster.
* Option B (Crisis Command):Centralized coordination, not mobile.
* Option C (Cold Site):Fixed, basic facility.
* Option D (Colocation):Shared fixed data center.
* "Mobile Recovery Centers provide a movable operating environment, deployable on transportable units for flexible recovery" (Module: Alternate Sites, Section: Mobile Solutions).

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).
