Cisco Certified Network Associate (CCNA) Practice Exam

Which command displays the OSPF interfaces and their associated details including IP address and network type?

1. #show ip ospf neighbor

2. #show ip ospf interface

3. #show ip protocols

4. #show ip route

The correct answer is: #show ip ospf interface

The command that displays OSPF interfaces along with their associated details, such as IP address and network type, is indeed the one described. When executed, this command provides a comprehensive overview of all interfaces participating in OSPF on the router. It includes crucial information such as the OSPF network type (e.g., broadcast, point-to-point, non-broadcast multi-access), the cost associated with each interface, and the OSPF status. This information is essential for diagnosing OSPF network configurations and understanding how OSPF will route packets across different network segments. Other commands listed serve different purposes. For example, the command that shows OSPF neighbor information provides details about adjacent OSPF routers and their state, which is important for understanding OSPF relationships but does not include interface-specific details. Similarly, the command that displays IP protocols offers insights into the general routing protocols configured on the router but lacks the targeted details provided by the correct command. Lastly, the command related to displaying the routing table focuses on overall routing information rather than interface-specific data for OSPF. Understanding the distinctions among these commands is key to effective network troubleshooting and management in a CCNA context.
