CCNA 2 Practice Final Exam V4.0 Answers

1.

R1 and R2 are adjacent routers both running RIP

Refer to the exhibit. R1 and R2 are adjacent routers both running RIP. All interfaces on both routers are correctly configured and operational. Both routers are configured to include all connected interfaces in routing updates. R2 is not showing any routes from R1 in the routing table. What is the likely cause?

The adjacent interfaces are passive.

The distance of 120 exceeds 15 hops.

R2 will not accept version 1 updates from R1.

Routes are being summarized by R1 but not by R2.

 

2.

Refer to the exhibit. Two routers are unable to establish an adjacency. What is the possible cause for this?

The two routers are connected on a multiaccess network.

The hello and dead intervals are different on the two routers.

They have different OSPF router IDs.

They have different process IDs.

1. Which two statements are true for link-state routing protocols? (Choose two.)

Routers that run a link-state protocol can establish a complete topology of the network.

Routers in a multipoint network that run a link-state protocol can exchange routing tables.

Routers use only hop count for routing decisions.

The shortest path first algorithm is used.

Split horizon is used to avoid routing loops.

1. What action does a link-state router take immediately upon receipt of an LSP from a neighboring router?

floods the LSP to neighbors

calculates the SPF algorithm

runs the Bellman-Ford algorithm

computes the best path to the destination network

 

2. Why is it difficult for routing loops to occur in networks that use link-state routing?

Each router builds a simple view of the network based on hop count.

Routers flood the network with LSAs to discover routing loops.

Each router builds a complete and synchronized view of the network.

Routers use hold-down timers to prevent routing loops.

run the SPF algorithm to find a new successor

search topology table for a feasible successor

Refer to the exhibit. Router B receives a packet with a destination address of 10.16.1.97. What will router B do?

drop the packet

forward the packet via the route to 10.16.1.0

forward the packet via the route to 10.16.1.64

use the default route

 

2. A network is converged and the routing tables are complete. When a packet needs to be forwarded, what is the first criterion used to determine the best path in the routing table?

the route with the smallest AD

the route with the longest address and mask match to the destination

the route with the highest bandwidth

the route with the best combination of AD and lowest cost

Refer to the exhibit. Routers East and West are configured using RIPv1. Both routers are sending updates about their directly connected routes. The East router can ping the West router serial interface and West can ping the serial interface of East. However, neither router has dynamically learned routes from the other. What is most likely the problem?

A gateway of last resort is required.

Subnetting is not supported by RIPv1.

VLSM is not supported by RIPv1.

One of the routers needs a clock rate on the serial interface.

Refer to the exhibit. The network that is shown is running RIPv1. The 192.168.10.0/24 network was recently added and will only contain end users. What command or set of commands should be entered on Router1 to prevent RIPv1 updates from being sent to the end user devices on the new network while still allowing this new network to be advertised to other routers?

Router1(config-router)# no router rip Router1(config-router)# network 192.168.10.0

Router1(config-router)# no network 192.168.10.0

Router1(config-router)# passive-interface fastethernet 0/0

Refer to the output from the show ip route command. What can be concluded from the output of this router command?

A preferred route to the destination has not been set.

There are two equal cost paths to network 1.0.0.0.

Both interfaces are being used equally to route traffic.

A variance must be set to load-balance across multiple paths.
