Which of the following duties would be a concern if
performed along with systems administration?
A. Maintenance of access rules
B. Review of system audit trail
C. Data librarian
D. Performance monitoring
Answer / guest
Answer: B
A system administrator performs various functions by using
the admin/root or an equivalent login. This login enables
the system administrator to have unlimited access to the
system resources. The only control over the system
administrator's activities is the system audit trail, hence,
it should be reviewed by someone other than the system
administrator. Maintenance of access rules, data librarian
functions and performance monitoring can be assigned to the
system administrator.
