You are configuring OSPF between two CX switches but cannot see any neighbors. Based on the output, how would you fix the problem?
The correct answer is A. Configure no ip ospf passive on the VLAN 102 interface. OSPF has been configured with passive-interface default, which makes all interfaces passive and stops them from sending OSPF hellos. VLAN 102 is therefore not forming adjacencies. Removing the passive setting for VLAN 102 (using the “no ip ospf passive” / “no passive-interface…

Explanation
OSPF has been configured with passive-interface default, which makes all interfaces passive and stops them from sending OSPF hellos. VLAN 102 is therefore not forming adjacencies. Removing the passive setting for VLAN 102 (using the “no ip ospf passive” / “no passive-interface vlan 102” equivalent) allows OSPF hellos and the neighbor relationship to form.
