A warm site offers a compromise between cost and recovery speed. It includes hardware and network infrastructure partially configured, allowing quicker recovery than a cold site but at lower cost than a hot site. Hot sites (A) enable rapid recovery but at high cost. Cold sites (B) are low cost but slow to recover. Manual (C) refers to manual processes, typically slower. Warm sites balance recovery time and cost in disaster recovery planning#6:Chapter 9 CompTIA Security+ Study Guide#.
