routing metric

MD5 authentication method


Refer to the exhibit. The network administrator needs to configure a default route on the border router. Which command correctly configures a default route that will require the least amount of router processing when forwarding packets?

ip route

ip route

4. What is indicated when an EIGRP route is in the passive state?

The route has the highest path cost of all routes to that destination network.

The route must be confirmed by neighboring routers before it is put in the active state.

The route is a feasible successor and will be used if the active route fails.

There is no activity on the route to that network.

The route is viable and can be used to forward traffic.

5. What is the purpose of the network command when RIP is being configured as the routing protocol?

It identifies the networks connected to the neighboring router.

It restricts networks from being used for static routes.

It identifies all of the destination networks that the router is allowed to install in its routing table.

It identifies the directly connected networks that will be included in the RIP routing updates.

6.What three statements are true about routers that are configured for EIGRP? (Choose three.)

They can support multiple routed protocols.

They can support only link-state protocols.

They send their entire topology tables to neighboring routers.

They send partial routing updates in response to topology changes.

They send routing updates to all other routers in the network.

They use hello packets to inform neighboring routers of their status.

7. A network administrator issues the command show ip route and observes this line of output: [120/2] via, 00:00:05, Serial0/0

What two pieces of information can be obtained from the output? (Choose two.)

RIP is the routing protocol that is configured.

This is a static route to network

The metric for this route is 2.

The next periodic update is in 5 seconds.

The autonomous system number is 120.


Refer to the exhibit. The network is configured with RIP routing. Which mechanism prevents R1 from sending an information update about network A to R3?

poisoned reverse

split horizon

holddown timers



Refer to the exhibit. R1 is not receiving updates from R2. Conversely, R2 is not receiving updates from R1. RIP version 1 is configured. All interfaces are up and functioning. The network statements are correct. All IP addressing is correct. What can be done to fix this problem?

Convert RIP version 1 to version 2 using the version 2 command..

Remove automatic classful summarization with the no auto-summary routing protocol command.

Replace RIP version 1 with version 2 and disable automatic classful summarization.

On both routers, configure the serial interface as a passive interface.

On both routers, change the subnet mask on the Fast Ethernet interface to be

10. When should EIGRP automatic summarization be turned off?

when a router has not discovered a neighbor within three minutes

when a router has more than three active interfaces

when a network contains discontiguous network addresses

when a router has less than five active interfaces

when a network addressing scheme uses VLSM

11. What two statements are correct regarding EIGRP authentication? (Choose two.)

EIGRP authentication uses the MD5 algorithm.

EIGRP authentication uses a pre-shared key.

EIGRP authentication requires that both routers have the same key chain name.

EIGRP authentication uses varying levels of WEP to encrypt data exchanged between routers.

EIGRP authentication can be configured on one router and updates from this router are protected; whereas a neighbor router can be without the authentication configuration and its updates are unprotected.


Refer to the exhibit. What three conclusions can be determined based on the exhibited commands? (Choose three.)

A link-state routing protocol is used.

A distance vector routing protocol is used.

Routing information updates are broadcast every 30 seconds.

Routing information updates are broadcast every 90 seconds.

Hop count is the only metric used for route selection.

Bandwidth, load, delay, and reliability are metrics that are used for route selection.


Refer to exhibit. What two features are true of the exhibited topology? (Choose two.)

introduces a single point of failure

is required when no downtime is acceptable

provides the maximum redundancy available

provides redundancy to critical areas

represents an extended star topology

is used to meet uptime and reliability requirements while limiting costs

14. What does a router that is running RIP use to determine the best path to take when forwarding data?

the host portion of the network address

the speed of network convergence

the calculated metric for the destination network

the number of broadcasts occurring on an interface

the number of errors occurring on an interface

15. What prevents RIPv1 updates from being correctly advertised?

an increase in network load

the use of variable length subnet masks

the use of multiple Layer 3 networks on the same router

a variation in connection speeds on the links to a destination

a mismatch between the configured bandwidth and the actual bandwidth of a link


Refer to the exhibit. How is the route significant to the EIGRP process?

This router is advertising a summary route to an EIGRP neighbor.

This router has the no autosummary command entered under the EIGRP routing process.

This router drops all packets that are destined to the IP address range.

This router has received a summary route from an EIGRP neighbor.

This router is using a summary route instead of a default route as a network design option.


Refer to the exhibit. A network administrator is troubleshooting a routing problem. When the show ip route command is entered on RTR-1, only the serial link between RTR-2 and RTR-3 has been learned from the RIP routing protocol. What are two issues? (Choose two.)

RIPv1 is a classful routing protocol.

RIPv1 does not support subnetting.

The Ethernet networks on RTR-2 and RTR-3 were not entered correctly in the network statements on these routers.

RIPv1 does not support VLSM.

RIPv1 is a classless routing protocol.


Refer to the exhibit. The routers are configured with EIGRP and with default K values. What is the routing path for a packet from network A to reach network B?

R1, R2, R5

R1, R3, R5

R1, R2, R3, R5

R1, R2, R4, R5

ip summary-address

ip summary-address eigrp 1
