Question

Options

• AThe directly connected route of interface GigabitEthernet 1/0/0 can be published to the OSPF database.
• BThe IP address of this interface cannot be used as the Router ID of OSPF.
• CThe interface cannot send any OSPF packets and will ignore the received OSPF packets.
• DThe OSPF process number of this router is 100.

• A
  79% (26)
• B
  21% (7)

Explanation

silent-interface (note the typo "sient-interface" in the question) is an OSPF command that suppresses all OSPF packet transmission and reception on the specified interface while still advertising that interface's connected network into the OSPF domain - making A correct (the route is published) and C correct (no OSPF packets are sent or received). D is correct because the OSPF process number is read directly from the prompt context [RTA-ospf-100], where 100 is the process ID. B is wrong because silent-interface has no effect on Router ID selection - the IP address of GigabitEthernet 1/0/0 remains a valid candidate for OSPF Router ID under normal election rules (manual config > loopback > highest active interface IP).

Memory tip: Think of silent-interface as a "publish-only stub" - the network gets advertised into OSPF, but the interface itself stays quiet (no Hellos, no adjacencies). It's commonly used on LAN segments with only end hosts, where you want OSPF to know the network exists but don't want rogue devices forming OSPF neighborships.
