Which of the following backup sites is the most effective for disaster recovery?
A.
Time brokers
B.
Hot sites
C.
Cold sites
D.
Reciprocal Agreement
Explanation:
Hot sites are a good choice for a company that needs to ensure a site will be available for it as soon as
possible. The only missing resources from a hot site are usually the data. A hot site is a facility that is leased or
rented and is fully configured and ready to operate within a few hours.
Incorrect Answers:
A: A time brokers backup solution would be less effective compared to hot or cold sites.
C: A cold site is less effective than a hot site since the cold site is a leased or rented facility that supplies the
basic environment, electrical wiring, air conditioning, plumbing, and flooring, but none of the equipment or
additional services. A cold site is essentially an empty data center.
D: Reciprocal agreements are less effective compared to hot or cold sites, since reciprocal agreements are
Enforceable. This means that although company A said company B could use its facility when needed, when
the need arises, company A legally does not have to fulfill this promise.Harris, Shon, All In One CISSP Exam Guide, 6th Edition, McGraw-Hill, 2013, p. 921
