Cisco Certified Network Associate (CCNA) 2025 – 400 Free Practice Questions to Pass the Exam

The correct way to specifically view OSPF hello messages on a Cisco device is achieved through the use of the command that directly targets OSPF related output. The command you mentioned provides detailed information about OSPF hello packets, including their frequency, the router IDs of neighbors, and other critical parameters that affect OSPF adjacency formation. By using this command, a network engineer can gain insights into how OSPF neighbors exchange hello packets, which is vital for troubleshooting OSPF issues related to router adjacency.

The other choices do not accurately reflect the command syntax or functionality necessary to view OSPF hello messages specifically. For example, while debugging commands can provide real-time information, they are more general, and monitoring commands may not be part of standard Cisco IOS command sets. Understanding the specific commands for OSPF can greatly assist in managing and troubleshooting OSPF configurations effectively.
