CCNA Routing and Switching (legacy) — Question 122

A router has learned three possible routes that could be used to reach a destination network. One route is from EIGRP and has a composite metric of 20514560.
Another route is from OSPF with a metric of 782. The last is from RIPv2 and has a metric of 4. Which route or routes will the router install in the routing table?

Answer options

• A. the RIPv2 route
• B. all three routes
• C. the OSPF and RIPv2 routes
• D. the OSPF route
• E. the EIGRP route

Correct answer: E

Explanation

The EIGRP route is the best choice because it has the lowest composite metric compared to the others. OSPF and RIPv2 metrics are significantly higher, making them less preferable for inclusion in the routing table. Therefore, the router will select the route from EIGRP.
