Which of the following represents the GREATEST risk created by a reciprocal agreement for disaster recovery
made between two companies?

A.
Developments may result in hardware and software incompatibility.

B.
Resources may not be available when needed.

C.
The recovery plan cannot be tested.

D.
The security infrastructures in each company may be different.

Explanation:
If one organization updates its hardware and software configuration, it may mean that it is no longer compatible
with the systems of the other party in the agreement. This may mean that each company is unable to use the
facilities at the other company to recover their processing following a disaster. Resources being unavailable
when needed are an intrinsic risk in any reciprocal agreement, but this is a contractual matter and is not the
greatest risk. The plan can be tested by paper-based walkthroughs, and possibly by agreement between thecompanies. The difference in security infrastructures, while a risk, is not insurmountable.
