Refer to the exhibit. All the routers are properly configured to use the RIP routing protocol with default settings, and the network is fully converged. Router A is forwarding data to router E. Which statement is true about the routing path?

Router A will send the data via the A-D-E path that is listed in the routing table.

Router A will load-balance the traffic between A-B-E and A-C-E.

Router A will determine that all paths have equal metric cost.

Router A will send the data through A-D-E and keep A-B-E and A-C-E as the backup paths.

A network administrator has enabled RIP on routers B and C in the network diagram. Which of the following commands will prevent RIP updates from being sent to Router A?

A(config)# router ripA(config-router)# passive-interface S0/0B(config)# router ripB(config-router)# network 192.168.25.48B(config-router)# network 192.168.25.64A(config)# router ripA(config-router)# no network 192.168.25.32B(config)# router ripB(config-router)# passive-interface S0/0

A(config)# no router rip

Refer to the exhibit. All router interfaces are configured with an IP address and are operational. If no routing protocols or static routes are configured, what information will be included in the show ip route command output for router A?

All of the 192.168.x.0 networks will be in the routing table.

Routes to networks 192.168.1.0/24, 192.168.2.0/24, and 192.168.3.0/24 will be in the routing table.

The routing table will be empty because routes and dynamic routes have not been configured.

A default route is automatically installed in the routing table to allow connectivity between the networks.

4

Refer to the exhibit. Routers R1 and R3 use different routing protocols with default administrative distance values. All devices are properly configured and the destination network is advertised by both protocols.

Which path will be used to transmit the data packets between PC1 and PC2?

The packets will travel via R2-R1.

The packets will travel via R2-R3.

The traffic will be load-balanced between two paths — via R2-R1 and via R2-R3.

The packets will travel via R2-R3, and the other path via R2-R1 will be retained as the backup path.

5

Refer to the exhibit. R1 knows two routes, Path A and Path B, to the Ethernet network attached to R3. R1 learned Path A to network 10.2.0.0/16 from a static route and Path B to network 10.2.0.0/16 from EIGRP. Which route will R1 install in its routing table?

Both routes are installed and load balancing occurs across both paths.

The route via Path B is installed because the EIGRP route has the best metric to network 10.2.0.0/16.

The route via Path A is installed because the static route has the best metric to network 10.2.0.0/16.

The route via Path B is installed because the EIGRP route has the lowest administrative distance to network 10.2.0.0/16.

The route via Path A is installed because the static route has the lowest administrative distance to network 10.2.0.0/16.

Refer to the routing table shown in the exhibit. What is the meaning of the highlighted value 192?

It is the value assigned by the Dijkstra algorithm that designates the number of hops in the network.

It is the value used by the DUAL algorithm to determine the bandwidth for the link.

It is the metric, which is cost.

It is the administrative distance.

Refer to exhibit. A company network engineer enters the following commands in the routers:

R1(config)# ip route 10.1.1.0 255.255.255.0 192.168.0.2R2(config)# ip route 10.1.2.0 255.255.255.0 192.168.0.1

When the engineer enters the show ip route command on R1, the routing table does not display the static route to the 10.1.1.0 network. All R1 and R2 interfaces are correctly addressed per the graphic. What is a logical next step that the engineer could take in order to make the static route display in the routing table in R1?

Enter default routes in R1 and R2.

Enable the R1 and R2 serial interfaces.

Configure the static route to use an exit interface instead of a next-hop address.

Enter the copy run start command to force the router to recognize the configuration.

The IP address of the S0/0/0 interface of R1 is 10.1.1.2.

The IP address of the S0/0/1 interface of R2 is 10.3.3.2.

R2 is connected to the S0/0/1 interface of R3.

10

Refer to the exhibit. Hosts on the BOS Fa0/0 LAN are able to ping the Fa0/1 interface on the JAX router and all interfaces on the BOS and ORL routers. Why would hosts from the 10.0.0.0/24 network not be able to ping hosts on the Fa0/0 LAN of the JAX router?

The JAX router has the wrong process ID.

The JAX router needs the network 10.0.0.0 0.0.0.255 area 0 command.

The JAX router needs the network 192.168.3.0 0.0.0.255 area 0 command.

The BOS router needs the network 192.168.3.0 0.0.0.255 area 0 command.
