You have the following routing table. Which of the following networks will not be placed in the neighbor routing table?

Ip Routing, Networking /
Question: You have the following routing table. Which of the following networks will not be placed in the neighbor routing table?

[A].

172.16.30.0

[B].

192.168.30.0

[C].

10.0.0.0

[D].

All of them will be placed in the neighbor routing table.

Answer: Option C

Explanation:

The network 10.0.0.0 cannot be placed in the next router’s routing table because it already is at 15 hops. One more hop would make the route 16 hops, and that is not valid in RIP networking.

You type debug ip rip on your router console and see that 172.16.10.0 is being advertised to you with a metric of 16. What does this mean?

Ip Routing, Networking /
Question: You type debug ip rip on your router console and see that 172.16.10.0 is being advertised to you with a metric of 16. What does this mean?
[A].

The route is 16 hops away.

[B].

The route has a delay of 16 microseconds.

[C].

The route is inaccessible.

[D].

The route is queued at 16 messages a second.

Answer: Option C

Explanation:

You cannot have 16 hops on a RIP network by default. If you receive a route advertised with a metric of 16, this means it is inaccessible.

A network administrator views the output from the show ip route command. A network that is advertised by both RIP and IGRP appears in the routing table flagged as an IGRP route. Why is the RIP route to this network not used in the routing table?

Ip Routing, Networking /
Question: A network administrator views the output from the show ip route command. A network that is advertised by both RIP and IGRP appears in the routing table flagged as an IGRP route. Why is the RIP route to this network not used in the routing table?
[A].

IGRP has a faster update timer.

[B].

IGRP has a lower administrative distance.

[C].

RIP has a higher metric value for that route.

[D].

The IGRP route has fewer hops.

Answer: Option B

Explanation:

RIP has an administrative distance (AD) of 120, while IGRP has an administrative distance of 100, so the router will discard any route with a higher AD than 100.

Question: Which of the following statements are true regarding the command ip route 172.16.4.0 255.255.255.0 192.168.4.2?

[A].

1 and 2

[B].

2 and 4

[C].

3 and 4

[D].

All of the above

Answer: Option A

Explanation:

Although answer D almost seems right, it is not; the mask is the mask used on the remote
network, not the source network. Since there is no number at the end of the static route, it is
using the default administrative distance of 1.

Question: Network 206.143.5.0 was assigned to the Acme Company to connect to its ISP. The administrator of Acme would like to configure one router with the commands to access the Internet. Which commands could be configured on the Gateway router to allow Internet access to the entire network?

[A].

1 only

[B].

3 only

[C].

1, 2 and 4

[D].

1 and 4

Answer: Option D

Explanation:

There are actually three different ways to configure the same default route, but only two are shown in the answer. First, you can set a default route with the 0.0.0.0 0.0.0.0 mask and then specify the next hop, as in option A. Or you can use 0.0.0.0 0.0.0.0 and use the exit interface instead of the next hop. Finally, you can use option D with the ip default-network command.
