Question 250
A branch design for Orion Shipping has two requirements: (1) stop unprotected VTY authentication with a shared weak line password, and (2) verify user identity before permitting an administrative login. Which proposed plan satisfies both outcomes?
Explanation
Correct Answer
Both outcomes are covered: (1) Per-user authenticated access supports accountability and avoids weak shared credentials. (2) Authentication proves who or what is requesting access. Neither action is a substitute for the other.
Incorrect Answers
Neither step is the requested pair: Inspect show access-lists counters on the device is for verify which ACL entries have matches during traffic tests, and Add approved static ARP ACL validation entries or equivalent supported bindings is for troubleshoot DAI dropping valid static-IP devices that lack DHCP bindings. IOS ACL match counters can show which permit or deny clauses see selected traffic. The proposed plan misses the two stated outcomes.
The first step covers (1), but the second addresses ensure a specific host denial is evaluated before a broad permit. IOS ACL processing uses the first matching entry, so later entries are not checked after a match. It leaves outcome (2) unfulfilled.
The second step covers (2), but the first addresses allow one IPv4 source host to reach a management subnet while denying others. Extended ACLs can match both source and destination address criteria for selective traffic policy. It leaves outcome (1) unfulfilled.
