Match each network symptom or issue on the left with its most likely underlying cause on the right.
- A workstation auto-assigns an IP address of 169.254.42.88 after connecting to an Ethernet port.DHCP server scope exhaustion or unreachability.
- Users experience frequent drops and poor throughput on a 2.4 GHz wireless network in an office with four nearby access points set to Channel 6.Co-channel interference and frequency overlap.
- A desktop experiences intermittent network access alongside operating system pop-up notifications warning of duplicate network addresses.IP address conflict from duplicate static assignment.
- A new Cat6 copper cable connection spanning 120 meters drops down to 100 Mbps instead of establishing a 1 Gbps link.Signal attenuation and distance limitation breach.
Answer
The client auto-assigning 169.254.x.x matches DHCP server scope exhaustion or unreachability; multiple access points operating on Channel 6 match co-channel interference; system notifications warning of duplicate addresses match IP address conflict from duplicate static assignment; and a Cat6 run over 120 meters dropping link speed matches signal attenuation and distance limitation breach.
Each item accurately pairs the observed networking symptom with its underlying root cause: APIPA (169.254.x.x) signals DHCP unreachability; multiple APs on channel 6 create 2.4 GHz co-channel interference; duplicate address pop-ups signify identical IP address assignment; and exceeding the 100m Ethernet specification leads to attenuation and degraded link speeds.
