Which site type uses portable units and is intended for rapid recovery?

• A. Warm Site
• B. Cold Site
• C. Hot Site
• D. Mobile Site

Answer: (D)

In disaster recovery planning, there are several options for an alternate operating location based on how quickly you can become fully functional. A mobile site uses portable, self-contained units that can be moved to the disaster site and set up with essential facilities, power, and connectivity. This makes it the fastest way to restore operations when a permanent facility isn’t available, since you can deploy it quickly and start running critical services with relatively low setup time.

This differs from a hot site, which is a fully equipped facility ready to take over immediately but is not portable and tends to be more costly; a warm site that has some infrastructure but requires more setup before it’s fully operational; and a cold site, which is just space with little to no equipment and requires substantial provisioning before use. The portable, rapidly deployable nature of a mobile site is what makes it the best fit for rapid recovery.
