An organization is preparing for a potential large-scale power outage during a severe weather event. They have invested in redundant power generators, uninterruptible power supplies (UPS), and have a warm-site data center in a geographically separate location. The warm-site is configured with hardware and network connectivity, but requires manual data restoration and application configuration. This entire strategy is an example of which recovery strategy?
- ACold Site
- BWarm Site
- CHot Site
- DMirror Site
Show answer & explanationAnswer & explanation
Correct answer: B. Warm Site
A warm site provides a balance between cost and recovery time. It has necessary hardware and network infrastructure but requires manual intervention for data restoration and application configuration, distinguishing it from a fully synchronized hot site and a bare-bones cold site.
Why the other options are wrong
- A. A Cold Site is a basic facility with space and power but no equipment, requiring significant time to become operational.
- C. A Hot Site is fully equipped and synchronized, allowing for near-instantaneous failover with minimal data loss.
- D. A Mirror Site (or active-active hot site) is a fully redundant, real-time synchronized environment, offering continuous operations.
Warm Site
A warm site is a type of disaster recovery site that has essential hardware and network connectivity pre-installed, but requires data to be restored from backups and applications to be configured, leading to a recovery time of hours to days.
- Balance of cost and recovery speed.
- Hardware and network in place.
- Requires data and application setup post-disaster.
Memory trick: Hot is 'Ready Now'; Warm is 'Ready Soon'; Cold is 'Start from Scratch'.
