An administrator is creating a redundant environment for a current data center. A backup site must
be available if the entire data center site should become unavailable. To reduce costs, this backup site
does not need to be up and running at all times ready for failover. It must contain equipment and the
ability to restore data from the data center. Which of the following site types should be considered to
meet these requirements?
A.
Hot site
B.
Warm site
C.
Cold site
D.
Active failover site
Cold Sites
-least expensive
-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.
-minimal start-up costs of the cold site
-requires additional time following the disaster to have the operation running at a capacity close to that prior to the disaster.
Hot Sites
-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.
-exists so that the organization can relocate with minimal losses to normal operations. Ideally, a hot site will be up and running within a matter of hours or even less.
Warm Sites
-compromise between hot and cold.
-have hardware and connectivity already established, though on a smaller scale than the original production site or even a hot site.
-will have backups on hand, but they may not be complete and may be between several days and a week old.
