Question 140
A network upgrade at North Quay Finance has two requirements: (1) gain SAE-based password authentication on a modern wireless LAN, and (2) ensure a specific host denial is evaluated before a broad permit. Which plan correctly handles both requirements?
Explanation
Correct Answer
Both outcomes are covered: (1) WPA3-Personal uses SAE for password-authenticated key establishment. (2) IOS ACL processing uses the first matching entry, so later entries are not checked after a match. Neither action is a substitute for the other.
Incorrect Answers
Neither step is the requested pair: Use accounting in an AAA architecture is for record when an administrator logs in and what actions occurred, and Enable dynamic ARP inspection with valid bindings and trusted infrastructure links is for stop forged ARP replies claiming the default gateway IP on user access ports. Accounting generates activity records for later auditing and troubleshooting. The proposed plan misses the two stated outcomes.
The second step covers (2), but the first addresses explain what ESP protects in common IPsec tunnels. ESP can encrypt payloads and provide authenticated integrity for protected packets. It leaves outcome (1) unfulfilled.
The first step covers (1), but the second addresses troubleshoot DAI dropping valid static-IP devices that lack DHCP bindings. DAI needs a trusted IP/MAC association for hosts without DHCP-snooping entries. It leaves outcome (2) unfulfilled.
