Difficulty: MediumBusiness Continuity and Disaster Recovery

An enterprise network operations team must select a secondary recovery facility for an internal administrative application. The Business Impact Analysis (BIA) establishes a Recovery Time Objective (RTO) of 24 hours and mandates strict budget controls. The disaster recovery strategy requires the facility to have active power, environmental controls, and telecommunications infrastructure in place, along with pre-racked server hardware, but continuous live data replication is not funded. Which disaster recovery site classification best meets these organizational requirements?

  1. A
    Hot site
  2. Warm siteAnswer
  3. C
    Cold site
  4. D
    Mobile site

Answer

Warm site
A warm site includes operational utilities, network infrastructure, and pre-installed server hardware, requiring only final data restoration and configuration upon disaster declaration. This makes it the most cost-effective solution capable of meeting a 24-hour Recovery Time Objective.

Step-by-Step Solution

1
Evaluate the Recovery Time Objective (RTO) and budget constraints provided in the scenario.
The target recovery window is 24 hours, and budget limitations exclude continuous live active-active data mirroring.
RTO defines the maximum acceptable duration of system unavailability following a disaster.
2
Compare site recovery parameters against standard disaster recovery location tiers.
A facility equipped with power, HVAC, network links, and pre-staged server hardware that requires backup restoration upon disaster declaration matches the warm site operational model.
Warm sites balance cost and recovery speed for target recovery windows ranging from several hours to a day.
