Refer to the exhibit. Router R4 is dynamically learning the path to the server. If R4 is connected to R1 via OSPF Area 20, to R2 via R2 BGP, and to R3 via EIGRP 777, which path is installed in the routing table of R4?

Question

Accepted Answer

C. the path through R2 because the EBGP administrative distance is 20 When a router learns multiple paths to the same destination from different routing protocols, it uses Administrative Distance (AD) to determine the most trustworthy path. External BGP (EBGP) has an administrative distance of 20, which is lower than OSPF's AD of 110 and EIGRP's (internal) AD of 90. Therefore, the path learned via EBGP through R2 will be preferred and installed in the routing table.

Answer

A. the path through R1, because the OSPF administrative distance is 110 OSPF's administrative distance is 110, which is higher than EBGP's AD of 20, so it would not be preferred.

Answer

B. the path through R2. because the IBGP administrative distance is 200 Internal BGP (IBGP) has an administrative distance of 200, which is much higher than EBGP's AD, making it less preferred. The connection to R2 is typically EBGP unless specified as IBGP.

Answer

D. the path through R3. because the EIGRP administrative distance is lower than OSPF and BGP EIGRP (internal) has an administrative distance of 90, which is lower than OSPF and IBGP but still higher than EBGP's AD of 20, thus it would not be the preferred path.
