What type of infrastructural setup is illustrated in the graphic that follows?

A.
Hot site

B.
Warm site

C.
Cold site

D.
Reciprocal agreement

Explanation:
A: A hot site is a facility that is leased or rented and is fully configured and ready to operate within a few hours. The only missing resources from a hot site are usually the data,
which will be retrieved from a backup site, and the people who will be processing the data. The equipment and system software must absolutely be compatible with the data being
restored from the main site and must not cause any negative interoperability issues. These sites are a good choice for a company that needs to ensure a site will be available for it as
soon as possible.
B is incorrect because a warm site is a leased or rented facility that is usually partially configured with some equipment, but not the actual computers. In other words, a warm site is
usually a hot site without the expensive equipment. Staging a facility with duplicate hardware and computers configured for immediate operation is extremely expensive, so a warm site
provides an alternate facility with some peripheral devices. This is the most widely used model. It may be a better choice for companies that depend upon proprietary and unusual
hardware and software, because they will bring their own hardware and software with them to the site after the disaster hits.
C is incorrect because a 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. It may take weeks to get the site activated and ready for work. The cold site could have equipment racks and dark fiber (fiber that does not have the
circuit engaged) and maybe even desks, but it would require the receipt of equipment from the client, since it does not provide any. The cold site is the least expensive option but takes
the most time and effort to actually get up and functioning right after a disaster.
D is incorrect because a reciprocal agreement is one in which a company promises another company it can move into its facility and share space if it experiences a disaster and vice
versa. Reciprocal agreements are very tricky to implement and are unenforceable. This is a cheaper way to go than the other offsite choices, but it is not always the best choice. Most
environments are maxed out pertaining to the use of facility space, resources, and computing capability.
