Question 50
During Lakeside Analytics's branch networking support, the technician encounters this condition: A desktop shows a 169.254.x.x address and can see a nearby printer but cannot reach the router. The desired outcome is to recognize IPv4 link-local APIPA as a DHCP reachability symptom. The customer requires a verified fix rather than a guess based on one symptom. Which planned change most directly resolves the documented issue?
- Configure the reachable 192.168.10.1 gateway on the office client
- Label short-range personal devices PAN, building networking LAN and multi-site WAN appropriately
- Use supported WPA3-Personal or appropriate WPA2-AES compatibility with strong credentials and retire WEP
- Restore correct DHCP reachability rather than treating the APIPA address as a routable internet address
Explanation
Correct Answer
D:
Restore correct DHCP reachability rather than treating the APIPA address as a routable internet address. It corrects the documented cause using the compatible technology and support constraints. The relevant observation is that a desktop shows a 169.254.x.x address and can see a nearby printer but cannot reach the router. The support goal is to recognize IPv4 link-local APIPA as a DHCP reachability symptom; this design action specifically addresses apipa 169.254.x.x missing dhcp lease without confusing a different subsystem.
