Which of the following activities performed by a database administrator (DBA) should be performed by a
different person?

A.
Deleting database activity logs

B.
Implementing database optimization tools

C.
Monitoring database usage

D.
Defining backup and recovery procedures

Explanation:
Since database activity logs record activities performed by the database administrator (DBA), deleting them
should be performed by an individual other than the DBA. This is a compensating control to aid in ensuring an
appropriate segregation of duties and is associated with the DBA’s role. A DBA should perform the other
activities as part of the normal operations.
