QUESTION NO:23

By default, which statement is correct regarding the redistribution of routes from other routing protocols into OSPF? Select the best response.

A. They will appear in the OSPF routing table as type E1 routes.

B. They will appear in the OSPF routing table as type E2 routes.

C. Summarized routes are not accepted.

D. All imported routes will be automatically summarized when possible.

E. Only routes with lower administrative distances will be imported.

Correct Answer: B Explanation

Explanation/Reference:

Type E1 external routes calculate the cost by adding the external cost to the internal cost of each link that the packet crosses while the external cost of E2 packet routes is always the external cost only. E2 is useful if you do not want internal routing to determine the path. E1 is useful when internal routing should be included in path selection. E2 is the default external metric when redistributing routes from other routing protocols into OSPF -> B is correct.

QUESTION NO:3

Refer to the exhibit. On the basis of the information presented, which statement is true?

RTA#show ip route ospf

O IA 6.0.0.0/8 {110/65] via 5.0.0.2, 00:00:18 Serial2/1/0

O*N2 0.0.0.0/0 [110/1] via 5.0.0.2, 00:00:18 Serial2/1/0

A. A default route is configured on the local router.

B. Network 6.0.0.0/8 was learned from an OSPF neighbor within the area.

C. OSPF router 5.0.0.2 is an ABR.

D. The default route is learned from an OSPF neighbor.

Correct Answer: C Explanation

QUESTION NO:11

Identify three characteristics of EIGRP feasible successors? (Choose three.)

A. A feasible successor is selected by comparing the advertised distance of a non-successor route to the feasible distance of the best route.

B. If the advertised distance of the non-successor route is less than the feasible distance of best route, then that route is identified as a feasible successor.

C. If the successor becomes unavailable, then the feasible successor can be used immediately without recalculating for a lost route.

D. The feasible successor can be found in the routing table.

E. Traffic will be load balanced between feasible successors with the same advertised distance.

Correct Answer: ABC Explanation

QUESTION NO:14

A network administrator is troubleshooting an EIGRP configuration across a discontiguous network. What must the administrator do to ensure the routers have the correct routing information?

A. Nothing, EIGRP supports discontiguous networks by default.

B. The administrator must disable automatic summarization with the command no auto-summary.

C. The administrator must enable manual summarization with the command ip summary-address.

D. The administrator must enable classless routing with the command ip classless.

E. The administrator must specify a default network with the command ip default-network.

Correct Answer: B Explanation Explanation/Reference:

QUESTION NO:18

A company has a BGP network and a BGP route of 196.27.125.0/24 that should be propagated to all of the devices. The route is not now in any of the routing tables. The administrator determines that an access list is the cause of the problem. The administrator changes the access list to allow this route, but the route still does not appear in any of the routing tables. What should be done to propagate this route?

A. Clear the BGP session.

B. Use the release BGP routing command.

C. Use the service-policy command to adjust the QOS policy to allow the route to propagate.

D. Change both the inbound and outbound policy related to this route.

Correct Answer: A Explanation

QUESTION NO:10

Refer to the exhibit. Given the exhibited router output, which command sequence can be added to R1 to generate a default route into the OSPF domain?

A. default-router

B. ip default-network

C. default-information originate always

D. ip default-gateway

Correct Answer: C Explanation

Explanation/Reference:

QUESTION NO:15

What is the purpose of the eigrp stub configuration command?

A. to increase scalability by limiting the EIGRP query range

B. to reduce the size of the routing table by blocking the D EX (External EIGRP) routes into the EIGRP stub router

C. to reduce the convergence time by enabling the EIGRP stub router to propagate the EIGRP queries from the EIGRP hub router

D. to reduce the convergence time by enabling the EIGRP stub router to also perform query requests to the EIGRP hub router

Correct Answer: A Explanation

Explanation/Reference:

The EIGRP Stub Routing feature improves network stability, reduce resources utilization, and simplifies stub router configuration. Stub routing is commonly used in a hub and spoke network topology. You need to configure the distribution (hub) and remote (spoke) routers to use EIGRP, and only the remote router as a stub. Only specified routes are propagated from the stub router. The router responds to queries for summaries, connected routes, redistributed static routes, external routes, and internal routes with the message “inaccessible”. A stub router will send a special peer information packet to all neighboring routers to report its status as a stub router. Any neighbor that receives a packet informing it of the stub status will not query the stub router for any routes, and a router that has a stub peer will not query that peer. The stub router will depend on the distribution router to send the proper updates to all peers.

QUESTION NO:12

D. backbone

E. ordinary or standard

Correct Answer: ADE Explanation

QUESTION NO:19

Refer to the exhibit. EIGRP is enabled on all routers on the network. What additional configuration is required for the routers connected over the Frame Relay multipoint interfaces to compensate for a low-speed NBMA connection?

A. Configure the EIGRP hello interval on all Frame Relay interfaces to 5 seconds.

B. Configure the EIGRP hello interval on all Frame Relay interfaces to 60 seconds.

C. Configure the EIGRP hold time on all Frame Relay interfaces to 15 seconds.

D. Configure the EIGRP hold time on all Frame Relay interfaces to 180 seconds.

E. Configure the bandwidth on all EIGRP Frame Relay interfaces to the committed information rate (CIR).

F. Configure the bandwidth on all EIGRP Frame Relay interfaces to the lowest CIR multiplied by the number of PVCs for the multipoint connection.
