Describe the difference between hot, warm, and cold site DR options.

Describe the difference between hot, warm, and cold site DR options.

• A. Hot sites are ready-to-run with data; warm sites require some setup; cold sites provide space with minimal infrastructure; recovery times vary accordingly.
• B. Hot sites require setup; cold sites are instantly usable; warm sites are offline.
• C. Warm sites replicate production data in real-time; hot sites never run production workloads; cold sites are virtual only.
• D. Cold sites have identical environments to production and require no setup.

Answer: (A)

Understanding disaster recovery site options and how ready they are to take over after a disruption is what this question is about. A hot site is designed to be ready to run immediately with up-to-date data and active services, so you can fail over with minimal downtime. A warm site has the hardware and connectivity in place but still needs some setup and data synchronization before it can take over, which means a longer but still manageable recovery time. A cold site is essentially an empty space with basic infrastructure; you must bring in and install equipment and restore data, leading to the longest recovery time but the lowest ongoing cost. The statement presented captures this progression by describing hot sites as ready-to-run with data, warm sites as requiring some setup, and cold sites as providing space with minimal infrastructure, with recovery times varying accordingly. The other options misstate readiness and timing—for example, hot sites aren’t just “requiring setup,” cold sites aren’t instantly usable, and warm sites aren’t inherently offline or lacking any data replication in all cases.
