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: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.

QUESTION NO:2

Refer to the exhibit. The DHCP configuration that is shown is configured on a Cisco router. Which statement is true?

ip dhcp pool 1

network 172.16.1.0/24

domain-name cisco.com

dns-server 172.16.1.102

netbios-name-server 172.16.1.103

default-router 172.16.1.100 172.16.1.101

lease 30

!

ip dhcp pool 1

network 172.16.2.0/24

domain-name cisco.com

dns-server 172.16.2.102

netbios-name-server 172.16.2.103

default-router 172.16.2.100 172.16.2.101

lease 30

A. The router will distribute IP addresses from pool 1 until its addresses are exhausted. Then the router will begin distributing addresses from pool 2.

B. The router will choose which pool to use based upon the interface the DHCP request was received on.

C. The configuration is invalid because the DHCP options are global configuration commands.

D. The configuration is incomplete until the DHCP pools are bound to the appropriate interface or interfaces.

QUESTION NO:24

Refer to the exhibit. What is required to complete the IPv6 routing configurations shown? Select the best response.

Router1#

interface S1/1

ipv6 address 2001:410:FFFF:1::1/64

ipv6 ospf 100 area 0

!

interface S2/0

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

ipv6 ospf 100 area 1

!

ipv6 router ospf

router-id 10.1.1.3

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.

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.
