Which choice below is the MOST accurate description of a warm site?

A.
A backup processing facility with adequate electrical wiring and air conditioning, but no hardware
or software installed

B.
A backup processing facility with all hardware and software installed and 100% compatible with
the original site, operational within hours

C.
A mobile trailer with portable generators and air conditioning

D.
A backup processing facility with most hardware and software installed, which can be operational
within a matter of days

Explanation:
The three most common types of remote off-site backup processing facilities are hot sites, warm
sites, and cold sites. They are primarily differentiated by how much preparation is devoted to the
site, and therefore how quickly the site can be used as an alternate processing site.
