An organization is seeking to implement a hot site and wants to maintain a live database server at
the backup site. Which of the following solutions will be the best for the organization?

A.
Electronic vaulting

B.
Remote journaling

C.
Remote mirroring

D.
Transaction logging

Explanation:
Remote mirroring is the most advanced and popular database backup solution. It
maintains a live database server at the backup site. The
remote server receives copies of the database modifications at that time when these modifications
are applied to the production server. This
production server is placed at the primary site. Thus, the mirrored server is ready to take over an
operational role at a moment’s notice.
Remote mirroring is a useful strategy for those organizations that are seeking to implement a hot
site. While considering the feasibility of a
remote mirroring solution, always be sure to take into account the infrastructure and personnel
costs that are required for supporting the
mirrored server as well as the processing overhead. The processing overhead is added to each
database transaction on the mirrored server.
Answer options A and B are incorrect. Electronic vaulting and remote journaling can be used for
database backup, but both of them cannot
work with the live database server.
