Which of the following should NOT be performed by an operator?

A.
Implementing the initial program load

B.
Monitoring execution of the system

C.
Data entry

D.
Controlling job flow

Explanation:
Under the principle of separation of duties, an operator should not be performing data entry. This should be left
to data entry personnel.
System operators represent a class of users typically found in data center environments where mainframe
systems are used. They provide day-to-day operations of the mainframe environment, ensuring that scheduled
jobs are running effectively and troubleshooting problems that may arise. They also act as the arms and legs of
the mainframe environment, load and unloading tape and results of job print runs. Operators have elevated
privileges, but less than those of system administrators. If misused, these privileges may be used to circumvent
the system’s security policy. As such, use of these privileges should be monitored through audit logs.
Incorrect Answers:
A: Implementing the initial program load is a function that should be performed by an operator.
B: Monitoring execution of the system is a function that should be performed by an operator.
D: Controlling job flow is a function that should be performed by an operator.
