Question 13 of 25

13. Question
2 points
Which two requirements are used to determine if a route can be considered as an ultimate route in a router’s routing table? (Choose two.)
- contain subnets
- be a default route
- contain an exit interface
- be a classful network entry
- contain a next-hop IP address
Correct

Incorrect

An ultimate route is a routing table entry that contains either a next-hop IP address (another path) or an exit interface, or both. This means that directly connected and link-local routes are ultimate routes. A default route is a level 1 ultimate route, but not all ultimate routes are default routes. Routing table entries that are subnetted are level 1 parent routes but do not meet either of the two requirements to be ultimate routes. Ultimate routes do not have to be classful network entries.

Question 14 of 25

14. Question
1 points
What is a disadvantage of using dynamic routing protocols?
- They are only suitable for simple topologies.
- Their configuration complexity increases as the size of the network grows.
- They send messages about network status insecurely across networks by default.
- They require administrator intervention when the pathway of traffic changes.
Correct

Incorrect

By default, dynamic routing protocols forward messages across a network without authenticating the receiver or originator of traffic. Static routes increase in configuration complexity as the network grows larger and are more suitable for smaller networks. Static routes also require manual intervention when a network topology changes or links become disabled.

Question 16 of 25

16. Question
2 points
Refer to the exhibit. Based on the partial output from the show ip route command, what two facts can be determined about the RIP routing protocol? (Choose two.)

CCNA 2 RSE 6.0 Chapter 3 Exam Answers 2018 2019 01
- RIP version 2 is running on this router and its RIP neighbor.
- The metric to the network 172.16.0.0 is 120.
- RIP version 1 is running on this router and its RIP neighbor.
- The command no auto-summary has been used on the RIP neighbor router.
- RIP will advertise two networks to its neighbor.
Correct

Incorrect

The router learned, via RIP, that 172.16.0.0 is variably subnetted, and that there are two subnet and mask entries for that network. This means that RIP version 2 is running on both routers and that the command no auto-summary has been applied on the neighbor router. RIPv2 has an administrative distance of 120 and this router will advertise all connected networks to the neighbor via 192.168.1.1.

A router is configured to participate in multiple routing protocol: RIP, EIGRP, and OSPF. The router must send a packet to network 192.168.14.0. Which route will be used to forward the traffic?
- a 192.168.14.0/26 route that is learned via RIP
- a 192.168.14.0/24 route that is learned via EIGRP
- a 192.168.14.0/25 route that is learned via OSPF
- a 192.168.14.0/25 route that is learned via RIP
Correct

Incorrect

Before the administrative distance of a route is compared, the route with the most specific best match is utilized. The 192.168.14.0/26 network contains the best match to the destination IP address of 192.168.14.20 and thus the 192.168.14.0/26 RIP route is utilized over the EIGRP and OSFP routes, regardless of administrative distance.

What is different between IPv6 routing table entries compared to IPv4 routing table entries?
- IPv6 routing tables include local route entries which IPv4 routing tables do not.
- By design IPv6 is classless so all routes are effectively level 1 ultimate routes.
- The selection of IPv6 routes is based on the shortest matching prefix, unlike IPv4 route selection which is based on the longest matching prefix.
- IPv6 does not use static routes to populate the routing table as used in IPv4.
Correct

Incorrect

Routers running IOS release 15 have link local routing table entries for both IPv4 and IPv6. The selection of both IPv6 routes and IPv4 routes is based on the longest matching prefix. The routing tables of both IPv6 and IPv4 use directly connected interfaces, static routes, and dynamically learned routes.
