The following figure shows the OSPF network of an enterprise and the OSPF configurations of...

 Silent Interface Explanation

The silent-interface command is used to prevent OSPF from sending or receiving OSPF packets on the specified interface (GE 0/0/1). This disables OSPF adjacency establishment and stops route advertisement for that interface.

 Network Observations

Statement A : R2 can access the server. This is correct, as the silent interface does not impact data traffic, only OSPF-related communication.

Statement B : GE 0/0/1 of R1 cannot send OSPF packets. Correct due to the silent-interface configuration.

Statement C : The network segment to which GE 0/0/1 of R1 belongs cannot be advertised. This is correct, as the silent interface prevents route advertisement.

Statement D : GE 0/0/1 of R1 cannot accept OSPF packets. Correct, as the silent interface configuration blocks packet reception.
