40–50 min15 Questions

Skills Tested

  • Understand dynamic routing vs static routing
  • Identify OSPF behavior and purpose
  • Analyze routing tables with OSPF entries
  • Understand OSPF neighbor relationships
  • Interpret OSPF states and CLI output
  • Calculate OSPF cost and best path selection
  • Troubleshoot OSPF adjacency issues
Progress0%

A company network has grown rapidly. Static routes are no longer scalable and OSPF has been deployed.

Reports:

  • !Some routers are not learning routes from neighbors
  • !Some paths are not optimal — traffic taking slower links
  • !Neighbor relationships may not be forming on all segments

Verify OSPF operation, analyze routing tables, troubleshoot adjacency issues, and determine correct best path selection.
