Refer to the provided OSPF network diagram with R1, R2, and a Server in Area 0, where R1's GigabitEthernet0/0/1 interface is configured for OSPF in Area 0 and connected to a segment including R2's…

Question

Options

• AR2 can access the server.
• BGE 0/0/1 of R1 will send OSPF packets.
• CThe network segment to which GE 0/0/1 of R1 belongs cannot be advertised.
• DGE 0/0/1 of R1 cannot accept OSPF packets.

• A
  4% (1)
• B
  4% (1)
• C
  85% (22)
• D
  8% (2)

Explanation

Option C is false because any interface actively configured for OSPF in an area will have its directly connected network advertised into the OSPF domain - so the 192.168.4.0/24 segment reachable via GE0/0/1 is fully advertised to OSPF neighbors, making the claim that it "cannot be advertised" incorrect. Option A is a true statement since R2 and the server share the same Area 0 network segment, giving R2 full IP reachability to the server. Option B is true because GE0/0/1 is an active OSPF interface and will transmit OSPF Hello packets to form and maintain neighbor adjacencies. Option D is true in this topology because a specific configuration (such as a passive-interface setting or an inbound filter on GE0/0/1) can prevent the interface from processing incoming OSPF packets, even while the network it belongs to remains advertised.

Memory tip: In OSPF, an interface enabled for OSPF always contributes its connected subnet to the link-state database. Whenever an answer choice says a network "cannot be advertised" for an OSPF-configured interface, that claim is false by definition.
