Referring to the exhibit, which of the following is the correct show ip route output for Router A to reach networks 208.149.23.64/27 and 208.149.23.96/27?

The correct answer is A. O 208.149.23.64 [110/13] via 190.173.23.10, 00:00:07, FastEthernet 0/0 O 208.149.23.96 [110/13] via 190.173.23.10, 00:00:16, FastEthernet 0/0. Based on the exhibit topology, both networks (208.149.23.64/27 and 208.149.23.96/27) are reached via the same next-hop address 190.173.23.10 through the FastEthernet 0/0 interface. The OSPF cost (metric) for both paths is the same: [110/13] (110 = OSPF AD, 13 = cost). Option A co

Question

Referring to the exhibit, which of the following is the correct show ip route output for Router A to reach networks 208.149.23.64/27 and 208.149.23.96/27?

Options

AO 208.149.23.64 [110/13] via 190.173.23.10, 00:00:07, FastEthernet 0/0 O 208.149.23.96 [110/13] via 190.173.23.10, 00:00:16, FastEthernet 0/0
BO 208.149.23.64 [110/13] via 190.173.23.10, 00:00:07, Serial 1/0 O 208.149.23.96 [110/3] via 190.173.23.10, 00:00:16, FastEthernet 0/0
CO 208.149.23.64 [110/13] via 190.173.23.10, 00:00:07, Serial 1/0 O 208.149.23.96 [110/13] via 190.173.23.10, 00:00:16, Serial 1/0 O 208.149.23.96 [110/13] via 190.173.23.10, 00:00:16, FastEthernet 0/0
DO 208.149.23.64 [110/3] via 190.173.23.10, 00:00:07, Serial 1/0 O 208.149.23.96 [110/3] via 190.173.23.10, 00:00:16, Serial 1/0

Explanation

Based on the exhibit topology, both networks (208.149.23.64/27 and 208.149.23.96/27) are reached via the same next-hop address 190.173.23.10 through the FastEthernet 0/0 interface. The OSPF cost (metric) for both paths is the same: [110/13] (110 = OSPF AD, 13 = cost). Option A correctly shows both routes pointing to FastEthernet 0/0 with identical metrics. Options B and C incorrectly reference Serial 1/0 and inconsistent metrics. Option D shows a cost of [110/3], which does not match the topology's calculated cost. Since both destinations are reachable via the same interface and next-hop, both entries use FastEthernet 0/0.
