Which of the following backup sites is most effective for disaster recovery?
A.
Time brokers
B.
Hot sites
C.
Cold sites
D.
Reciprocal agreement
Explanation:
Hot sites, while the most expensive, turnaround can be near complete
within a couple of hours of the disaster.
A cold site is the least expensive type of backup site for an organization to operate. It does not include backed up copies of data and information from the original location of the organization, nor does it include hardware already set up.
A warm site is a compromise between hot and cold. These sites will have hardware and connectivity already established, though on a smaller scale than the original production site or even a hot site.
A hot site is a duplicate of the original site of the organization, with full computer systems as well as near-complete backups of user data. Real time synchronization between the two sites may be used to completely mirror the data environment of the original site using wide area network links and specialized software
