//IMG// Refer to the exhibit. Which type of route does R1 use to reach host 10.10.13.10/32?

Selected Answer: B A. default route The default route is 0.0.0.0/0, it is used to reach all destinations not included in the routing table. But the router already has a route to 10.10.13.10/32. The default route is not needed. Wrong answer. B. network route The routing table includes a route to 10.10.13.0/25. This subnet has these characteristics: 7 bits in the host ID = (2^7 – 2) = 126 IP addresses 1st IP address = 10.10.13.1 Last IP address = 10.10.13.126 This route includes address 10.10.13.10 and is an OSPF route (see the leading O). Correct answer. C. host route There’s no host route in the routing table. Wrong answer. D. floating static route A floating static route is used as a “backup” route to reach a subnet when the “main” route fails. But here the route to the host’s subnet is already in the routing table, and it is working. Wrong answer.
