Question 1

Refer to the exhibit. An engineer configured R6 as the headend LSR of an RSVP-TE LSP to router XR2, with the dynamic path signaled as R6-R2-R5-XR2. and set the OSPF cost of all links to 1. MPLS autotunnel backup Is enabled on all routers to protect the LSP. Which two NNHOP backup tunnels should the engineer use to complete the implementation? (Choose two.)

Options :

A : The R6 backup tunnel path R6-R1-R4-R5.

B : The R2 backup tunnel path R2-R5 across the alternate link.

C : The R2 backup tunnel path R2-R1-R4-XR1-XR2.

D : The R6 backup tunnel path R6-R2-R5

E : The R6 backup tunnel path R6-R1-R2.

Answer: A,C

Question 2

Refer to the exhibit.

A network administrator implemented MPLS LDP changes on PE-A LSR device. The engineer must ensure

there are no LDP peer are fully operational. Which LDP feature must the engineer apply to the existing

configuration to eliminate the problem?

Options :

A :

Configure MPLS LDP IGP synchronization on the network.

B : Configure MPLS LDP NSR for all LDP sessions.

C : Enable LDP session protection under the routing protocol.

D : Disable IP CEF on routers running LDP and enable LDP.

Answer: B

Question 3

Refer to the exhibit. Router R1 is configured with class map CE with match Ip precedence critical to align

with customer contract SLAs. The customer is sending all traffic from CE1 toward the FTP server with IP

precedence 5 A network engineer must allow 10% of interface capacity on router R3 Which two actions must

the engineer take to accomplish the task? (Choose two )

Options :

A : lmptem4Dt4M$§ map on R1 to match all packets with QoS IP precedence value 100.

B : Implement a class map on R3 to match all packets with QoS IP precedence value 101.

C : Apply a policy map to R1 to reserve the remaining 10% of interface bandwidth.

D : Apply a policy map to R3 to reserve 10% of interface bandwidth.

E : Implement a class map on R3 to match all packets with QoS IP precedence.

Answer: C,D

Question 4

Refer to the exhibit. An engineer is scripting ACLs to handle traffic on the given network. The engineer must

block users on the network between R1 and R2 from leaving the network through R5. but these users must still

be able to access all resources within the administrative domain. How must the engineer implement the ACL configuration?

Options :

A :

Configure an ACL that permits traffic to any internal address, and apply it to the R5 interfaces to R3 and R4 in the egress direction

B :

Configure a permit any ACL on the R1 interface to R2 in the egress direction, and a deny any ACL on the interface in the ingress direction

C :

Configure an ACL that permits traffic to all internal networks and denies traffic to any external address, and apply it to the R2 interface to R1 in the ingress direction.

D :

Configure an ACL that denies traffic to any internal address and denies traffic to any external address, and apply it to the R5 interfaces to R3 and R4 in the ingress direction

Answer: C

Question 5

Refer to the exhibit.

An engineer is implementing BGP selective prefix suppression. The router must advertise only 10.16.4.0/24,10.16.5.0/24. and summarized route 10.16.0.0/21. and suppress 10.16.6.0/24. Which configuration must the engineer apply to the router?

Options :

A :

B :

C :
