Question 1

Refer to the exhibit.

A service provider technician is working on a multicast issue for a customer. While

checking the multicast table, the technician notices that no flags are present for the (1.1.1.1, 239.1.1.1) entry, yet flags are present for the (1.1.1.1, 232.1.1.1) entry.

Which factor might explain this issue?

Options :

A : Only the administratively scoped range is permitted

B : Only ASM is permitted

C : Only the default SSM range is permitted

D : Only GLOP is permitted

Answer: C

Question 2

Refer to me exhibit.

A network engineer sets up a multihoming eBGP topology where multiple Autonomous Systems connect to ASN 64501. The engineer wants to block all the routers coming from ASN 64502. but allow all the others. For that purpose, the following AS Pam prefix 1st s being used:

What must be fixed to achieve this result?

Options :

A : The AS-PATH filter must be defined inside the route-map mode

B : At the end ip as-path access-list 10 permit .* must be included

C : The statement must be modified with ip as-path access-list 1 deny _64502_

D : The statement must CM modified with ip as path access list 1 deny A64502$

Answer: B

Question 3

Refer to the exhibit MPLS traffic from the packet core that is connected to router RX (10 10 101) to the radio network that is connected to router RB (10 10 10 6) uses the longer route RB R2 RY RX RX and R2 are configured with a default value of LDP hello and hold intervals The team verified that OSPF neighborship in Area 0 is established between RX and R2 Which action must be taken to choose the shortest path and resolve the issue?

Options :

A :

B :

C :

D :

Answer: B

Question 4

Refer to the exhibit.

IS-IS is the routing protocol on the network. After the team noticed excessive CPU usage on all routers, particularly routers R2 and R6, they configured route summarization on all routers. However, a network engineer noticed that summary routes and more specific routes are present in the routing table on R1. Which action must the team take so that R1 receives only the summary routes?

Options :

A : Configure R2 and R4 to perform summarization for Level 1 routers.

B :

Configure R3 to perform summarization for Level 1 routers, and configure R6 to perform summarization for Level 2 routers.

C : Configure R3 and R5 to perform summarization for Level 1 and Level 2 routers.

D : Configure R6 only to perform summarization for all routers.

Answer: B

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.
