Using another company’s facilities in the event of a disaster is called what?

A.
Rolling hot site

B.
Redundant site

C.
Merger

D.
Reciprocal agreement

Explanation:
Reciprocal agreements with other companies can be a cheap alternative
to disaster recovery but are very difficult to enforce legally. A reciprocal
agreement is not enforceable, meaning that the company that agreed to let the
damaged company work out of its facility can decide not to allow this to take place.
A reciprocal agreement is a better secondary backup option if the primary plan falls
through.
