Question 1

What is the function of BGP confederations?

Options :

A : They require routers to use private AS numbers.

B : They eliminate the need for a fully-meshed internal BGP design.

C : They enable a single device to distribute a common configuration to its peers

D : They assign an external BGP router to serve as the route reflector

Answer: B

Question 2

Refer to the exhibit.

Refer to the exhibit. CE1 and CE2 use connectivity over the service provider cloud to reach CE3 In the event of a link failure in the service provider cloud which BGP feature relies on IGP convergence to quickly assist in the installation of a backup path?

Options :

A : BGP graceful restart

B : BGP route dampening

C : BOP PIC core

D : BGP confederations

Answer: C

Question 3

Refer to the exhibit. Users connected to an application on 1.1.1.1 via routers CE1 and CE2 are complaining of frequent disconnections. While troubleshooting the issue, a network engineer with an employee ID: 4333:96:916 determined that the application itself is working normally, but the link connected to the 1.1.1.1 application is flapping. The users on CE1 and CE2 are accessing applications on 2.2.2.2 without difficulty. Which action resolves the issue?

Options :

A : Disable split horizon on router R2.

B : Redistribute CE1 routes on router R2.

C : Enable passive interface on the router R3 Loopback1 interface.

D : Enable route dampening on routers R1 and R2

Answer: D

Question 4

Refer to the exhibit.

Refer to the exhibit A network engineer installed a new router (router 3) at the regional hub running MPLS services for scalability Router 3 is connected to the 10.44 4.0,'24. 10.44 5.024. 10 44.6.0/24. and 10 44 7 0/24 subnets The new router has been configured for OSPF area 2. and it is advertising the four connected networks. The engineer noticed that the same networks are listed as interarea summary routes, and they are being flooded into each area on the area borders Which action resolves the issue?

Options :

A : On router 3, configure an access list to filter the networks.

B : On router 2, configure a route map to filter the networks.

C : Under the OSPF configuration on router 3. add area 2 range 10.44.4.0 255.255.252.0.

D : Under the OSPF configuration on router 2, add area 2 range 10.44.4.0 255.255.252.0.

Answer: D

Question 5

Refer to the exhibit.

The four routers in this network have formed adjacencies. Router R2 is an IS-IS level 1-2 router that connects to other areas, and the attach bit is set in the R2 level 1 LSP advertisements to R1. According to the network design, R2 should push level 2 routes from its routing table to the R1 routing table. However, R1 installed a default route in its routing table. Which action resolves this problem?

Options :

A :

Use The is-type level-1-2 backdoor command lo unset the attach bit on R1 and use a prefix List to filter prefixes from R2

B : Set the attach bit on R1and use a prefix list to filter prefixes from R2.

C :

Use the is-type level-1-2 backdoor command to unset the attach bit on R2 and configure a distribute-list to redistribute prefixes to R1

D : Configure R2 as a level 1 router and use a prefix list to filter prefixes to R1.
