Temporarily deactivating some monitoring processes, even if supported by an acceptance of operational risk,
may not be acceptable to the information security manager if:

A.
it implies compliance risks.

B.
short-term impact cannot be determined.

C.
it violates industry security practices.

D.
changes in the roles matrix cannot be detected.

Explanation:

Monitoring processes are also required to guarantee fulfillment of laws and regulations of the organization and,
therefore, the information security manager will be obligated to comply with the law. Choices B and C are evaluated as part of the operational risk. Choice D is unlikely to be as critical a breach of regulatory legislation.
The acceptance of operational risks overrides choices B, C and D.
