A 911 PSAP engineer confuses EIGRP passive-interface with interface shutdown on a link that should advertise its subnet but not form a neighbor. Which statement correctly contrasts the two?
Select an answer to reveal the explanation.
Short Explanation
Passive mutes the EIGRP conversation on that NIC but the subnet can still show up via other active interfaces. Shutdown kills the NIC—no hellos, no forwarding, lights out. For “advertise but don’t peer,” you want passive, not a hard shut.
Full Explanation
Passive-interface prevents EIGRP hello/adjacency on the interface while the connected network can still be originated from the EIGRP process via other interfaces. Interface shutdown administratively disables the link, removing normal forwarding and adjacency on that interface. Treating them as identical—or assuming passive blocks data plane while keeping adjacency—misguides PSAP change windows.
