Question 1

Refer to the exhibit Router 1 resides in a different data center than Rouler 2 and Router 3. Router 1 is running the IS-IS routing protocol, and it is preconfigured with LDP and segment routing Which configuration must the engineer apply under router isis 111 on Router 1 to implement Tl-LFA on the link to Router 2 without disrupting traffic to Router 3?

Options :

A :

B :

C :

D :

Answer: D

Question 2

Refer to the exhibit.

Refer to the exhibit. After a recent network implementation project, customer A is performing stress testing to verify network redundancy at the branch office connected to R4. When the link from R2 is shut own as shown, the SLA tracking object fails and the cost of the link between R2 and R4 increases to 100. However, a traceroute operation from a PC in the Branch office shows that traffic to HQ is still routed via R2. Which solution corrects the problem and optimizes traffic flow via R3 without creating operational overhead?

Options :

A : Configure two OSPF processes on R2 and R3 and redistribute traffic between them.

B : Redistribute routes from BGP to OSPF as type El.

C : Use multiarea adjacency to extend Area 10 to the link between R2 and R3.

D : Create a virtual channel from R3 to R4.

Answer: B

Question 3

What is the difference between basic IS-IS and OSPF packet types?

Options :

A : IS-IS and OSPF use area packets, but only IS-IS uses sequence number packets.

B : IS-IS and OSPF use link-state update packets, but only OSPF uses link-state ACK packets.

C : IS-IS and OSPF use Hello packets, but only OSPF uses DBD packets.

D : IS-IS and OSPF use link-state update packets, but only IS-IS uses DBD packets.

Answer: C

Question 4

Refer to the exhibit. A network engineer must correct the security policy on the EDGE_R router, which is connected to two Tier 1 ISPs. After another engineer added ip as-path access-list 11 permit 11 to EDGE_R, some routes from AS 11 and AS 4832 started to appear in the routing information base (RIB). Traffic control via Community options is disabled on both ISPs. How should the network engineer update the router configuration on EDGE_R so that only routes for AS 11 are permitted?

Options :

A : Configure ip as-path prefix-list 11 permit _11$.

B : Configure ip as-path access-list 11 permit _11_.

C : Configure ip as-path distribution-list 11 deny A[0-9]+S.

D : Configure ip as-path access-list 11 deny 4832$.

Answer: D

Question 5

RPL has several fundamental capabilities that differ from those present in configurations oriented to traditional route maps Routing policy language introduces the notion of sets Which group of set types is valid in RPL?

Options :

A : acl-path-set community-set pre-community-set prefix-set and bgp-set

B : as-path-set community-set. extcommunity-set prefix-set and rd-set

C : access-control-set, community-set post-community-set pre-prefix-set and routed-set

D : route-path-set, community-set in-community-set prefix-set and rd-set
