Alternate Site for Infrastructure

D.

The correct answer is D. Cold site.

A cold site is an alternate site where only the infrastructure has been established. It is a backup site that provides the basic infrastructure necessary for a company to resume its operations in the event of a disaster. However, it does not have any equipment or systems installed, and the company must install and configure its own systems before it can resume operations. This can take a significant amount of time, which makes cold sites less desirable than other types of disaster recovery sites.

A warm site, on the other hand, is a backup site that has some of the equipment and systems installed, but they are not operational. The company must install and configure its own systems before it can resume operations, but this process is faster than it would be at a cold site.

A hot site is a backup site that is fully operational and can take over immediately if the primary site fails. It has all the equipment and systems installed and configured, and it is kept up-to-date with the latest data and applications.

A mirror site is a type of hot site that is an exact replica of the primary site. It is typically used for high-availability applications that cannot tolerate any downtime.

In summary, a cold site provides only the infrastructure, while the other types of sites provide additional levels of redundancy and faster recovery times. The choice of site depends on the specific needs of the organization and the level of risk it is willing to tolerate.
