Which one of the following alternative processing sites takes the longest time to activate?
A. Hot site
B. Mobile site
C. Cold site
D. Warm site
Chapple, Mike; Stewart, James Michael; Gibson, Darril. (ISC)2 CISSP Certified Information Systems Security Professional Official Study Guide (p. 841). Wiley. Kindle Edition.
C. Cold site
Explanation:
The cold site contains none of the equipment necessary to restore operations. All of the equipment must be brought in and configured and data must be restored to it before operations can commence. This often takes weeks.

C. 12 hours
Explanation:
Warm sites typically take about 12 hours to activate from the time a disaster is declared. This is compared to the relatively instantaneous activation of a hot site and the lengthy time (at least a week) required to bring a cold site to operational status.

Which one of the following items is a characteristic of hot sites but not a characteristic of warm sites?
A. Communications circuits
B. Workstations
C. Servers
D. Current data
Chapple, Mike; Stewart, James Michael; Gibson, Darril. (ISC)2 CISSP Certified Information Systems Security Professional Official Study Guide (p. 842). Wiley. Kindle Edition.
D. Current data
Explanation:
Warm sites and hot sites both contain workstations, servers, and the communications circuits necessary to achieve operational status. The main difference between the two alternatives is the fact that hot sites contain near-real-time copies of the operational data and warm sites require the restoration of data from backup.

What type of database backup strategy involves maintenance of a live backup server at the remote site?

D. Remote mirroring
Chapple, Mike; Stewart, James Michael; Gibson, Darril. (ISC)2 CISSP Certified Information Systems Security Professional Official Study Guide (p. 842). Wiley. Kindle Edition.
D. Remote mirroring
Explanation:
Remote mirroring is the only backup option in which a live backup server at a remote site maintains a bit-for-bit copy of the contents of the primary server, synchronized as closely as the latency in the link between primary and remote systems will allow.
