A route learned from a neighboring router using EIGRP appears in the route table with which letter?

• A. D
• B. C
• C. S
• D. O

Answer: (A)

In a router’s routing table, each entry carries a code that shows how that route was learned. When a route is learned from a neighboring router using EIGRP, it gets the code D. This D stands for EIGRP (the routing protocol that provided the path). So, a route learned via EIGRP will appear with the D code, distinguishing it from routes that are directly connected (C), statically configured (S), or learned through other protocols like OSPF (O).
