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: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:1

Which statement is true about the implementation of IPv6 in an already existing IPv4 network?

A. IPv6 can be routed using the same routing protocol versions as IPv4

B. A router routing for IPv6 and IPv4 must convert IPv4 packets to IPv6 packets to route them.

C. IPv4 and IPv6 networks can be routed simultaneously.

D. Only OSPF version 3 can be utilized for routing IPv4 and IPv6.

Correct Answer: C Explanation

Explanation/Reference:

QUESTION NO:24

ipv6 ospf 100 area 0

!

interface S2/0

ipv6 address 3FFF:B00:FFFF:1::2/64

Router2#

interface S3/0

ipv6 address 3FFE:B00:FFFF:1::1/64

ipv6 ospf 100 area 1

ipv6 router ospf 100

router-id 10.1.1.4

A. Interface authentication must be configured.

B. The routing processes must be configured with an area ID.

C. IPv6 unicast-routing must be enabled.

D. IPv4 addresses must be applied to the interfaces.

Correct Answer: C Explanation

QUESTION NO:5

Refer to the exhibit. EIGRP is configured on all routers in the network. On the basis of the output provided, which statement is true?

A. Because the key chain names do not match, router R1 will not be able to ping routers R2 and R3 .

B. Because the key strings do not match, router R1 will not be able to ping routers R2 and R3.

C. Because authentication is misconfigured on interfaces Gi0/0 and Gi0/1 on router R2, router R1 will not be able to ping routers R2 and R3.

D. Because autosummarization needs to be turned on for EIGRP on all routers, router R1 will not be able to ping routers R2 and R3.

E. Router R1 will be able to ping routers R2 and R3.

Correct Answer: E Explanation

QUESTION NO:17

Which command displays statistics on EIGRP hello, updates, queries, replies, and acknowledgments?

A. debug eigrp packets

B. show ip eigrp traffic

C. show ip eigrp topology

D. show ip eigrp neighbors

Correct Answer: B Explanation

Explanation/Reference:

QUESTION NO:8

Which is the correct command format to configure EIGRP summary route?

A. ip auto-summary as-number address mask

B. ip summary-address as-number address mask

C. ip auto-summary eigrp as-number address mask

D. ip summary-route eigrp as-number address mask

E. ip summary-address eigrp as-number address mask

QUESTION NO:6

A network administrator is troubleshooting a redistribution of RIP routes into OSPF. Given the exhibited commands, which statement is true?

router rip

network 10.0.0.0

!

router ospf 5

network 172.10.0.0 0.0.255.255 area 0

redistribute rip

A. Redistributed routes will have an external type of 1 and a metric of 1.

B. Redistributed routes will have an external type of 2 and a metric of 20.

C. Redistributed routes will maintain their original OSPF routing metric.

D. Redistributed routes will have a default metric of 0 and will be treated as reachable and advertised.

E. Redistributed routes will have a default metric of 0 but will be treated as unreachable and not advertised.

Correct Answer: B Explanation

Explanation/Reference:

By default, all routes redistributed into OSPF will be tagged as external type 2 (E2) with a metric of 20, except for BGP routes (with a metric of 1).

Note: The cost of a type 2 route is always the external cost, irrespective of the interior cost to reach that route. A type 1 cost is the addition of the external cost and the internal cost used to reach that route.
