Which DR site type provides up-to-date data and can run immediately?

• A. Warm site is ready to run immediately with up-to-date data.
• B. Cold site is ready to run immediately with up-to-date data.
• C. Hot site is ready to run immediately with up-to-date data.
• D. Cold site with backups in cloud.

Answer: (C)

In disaster recovery, the speed at which you can resume operations depends on how ready the site is and how current its data is. A hot site is a fully configured, redundant data center that holds up-to-date copies of the production systems and data, so you can fail over and continue almost instantly. This means zero or near-zero downtime and no data loss, since the environment is already running and synchronized. A warm site has equipment and some data ready but isn’t fully synchronized or active yet, so it requires some steps to bring systems online and catch up on data. A cold site is only a space with no running systems, so you must install hardware and restore data from backups, leading to significant downtime. Even a cold site with backups in the cloud still needs time to restore and bring everything online.
