Question 640
An identity and device-administration engineer evaluates: A switch accepts a network engineer's password but the engineer can access unrestricted privileged configuration because command authorization was never enabled. Which technical behavior is MOST relevant to this design?
Explanation
Correct Answer
Authentication answers who logged in; authorization controls what commands that identity may execute. This behavior directly governs the stated requirement. The recommended action is: Implement supported TACACS+ command authorization and scoped command sets in addition to authentication. The acceptance result is: An authorized read-only operator runs show commands but cannot execute a prohibited configuration command.
Incorrect Answers
Maintain protocol-specific AAA network port and service documentation. The repeat risk here is different: Audit device-admin accounting coverage for privileged changes. A directly relevant preventive control is: Authentication answers who logged in; authorization controls what commands that identity may execute.
Use stage-specific posture error classification instead of broad credential resets. The repeat risk here is different: Audit device-admin accounting coverage for privileged changes. A directly relevant preventive control is: Authentication answers who logged in; authorization controls what commands that identity may execute.
Apply a restricted TACACS+ command set that permits only required commands and denies sensitive configuration changes. The repeat risk here is different: Audit device-admin accounting coverage for privileged changes. A directly relevant preventive control is: Authentication answers who logged in; authorization controls what commands that identity may execute.
