An engineer has successfully fixed BGP peering issue. R1 has an established eBGP peering with R2 and R3. Which mechanism should the engineer apply in order to steer the traffic correctly?

A. The MED attribute can be applied on R2 to influence R1 to use it as the primary path.

B. The local preference attribute can be applied on R3 to influence AS 65513 to use AS 65515 as the secondary path.

C. The weight attribute can be applied on R2 to influence AS 65513 to use AS 65515 as the primary path.

D. The IGP metric can be manipulated on R1 to allow traffic to be load balanced between R2 and R3.

Refer to the exhibit.

ISP_1 uses eBGP for connection to all clients LDP with OSPF and IS-IS is used in the ISP_1 network Client_A and Client_B are in the same VRF_VoD. After oftware upgrade on all routers on the ISP_1 network, Client_A has lost the connection to Client_C. A network engineer must troubleshoot the connection from R1 to R4 via M. After initial checks, the engineer confirmed that all routes are installed correctly. Which two tasks must the engineer perform to correct the problem? (Choose two.)

A. Configure next-hop-self under the BGP configuration on R42.

B. Configure mpls label implicit-null under the global configuration on R31.

C. Configure next-hop-unchanged under the BGP configuration on R31.

D. Configure ip cef under the global configuration on R31.

E. Configure send-label under the BGP configuration on R42

Drag and drop the attributes for the BGP route selection on the left into the correct order on the right. Not all options are used.

Which IPv6 prefix format defines the destination of a dynamic 6to4 tunnel?

A. 2001:db8::/32

B. 2002::/16

C. fe80::/10

D. ff00::/8

Refer to the exhibit.

An engineer is troubleshooting a network routing issue on this IS-IS network situated at the customer's regional hub. Router 2 that runs Cisco IOS XR Software cannot see the network 10.1.1.0/24 on router 1. The Layer 2 encapsulations are correct. The ARP connectivity for the Ethernet interface that runs IS-IS is working. Which action resolves the issue?

A. On router 1, remove the CISCOLIVE keyword after the Ip router Isis command under interface GigabitEthernet0/2.

B. Under the router isis command on router 1. change is-type level-1 to is-type level-2

C. On router 1. add the CISCOLIVE keyword after the Ip router isis command under interface GigabitEthernet0/3.

D. Under the router isis command on router 2. change is-type level-1 to is-type level-2

Refer to the exhibit.

An administrator is troubleshooting network issues on a customer’s network PE1 cannot form an LDP relationship with PE2 using LDP ID 192 168.1.1. Due to this connectivity issue, the customer’s routes behind both PE routers cannot be exchanged. Which action must the administrator take to correct the problem?

A. Configure PE2 to automatically select its own LDP router ID with 192.168.1.1.

B. Create a targeted LDP session on PE2 to override the missing routing table entry on PEL

C. Configure PE1 with a static route to 192 168.1.1.

D. Enable LDP session protection on the link that P1 uses as the next hop to PE2.

Refer to the exhibit.

A company has been running OSPF and EIGRP on two separate portions of the network To allow communication flow between these previously isolated parts of the business the networking team just configured R2 to mutually redistribute routes between EIGRP and OSPF R3 has the OSPF routes in its routing table but R1 is failing to receive EIGRP routes for the link between R2 and R3 Which action must the team take to resolve the issue?

A. Configure EIGRP on R1

B. Configure the redistribution statement with the subnets keyword under the R2 OSPF configuration

C. Configure a virtual link between R1 and R2 to handle traffic without an assigned area

D. Configure R1 with a static route with the next hop set to R3 with the vrf keyword to avo»d the global routing table

Refer to the exhibit Dedicated MPLS Layer 3 services for VRF customer A are configured on the MPLS network for FTP access OSPF with area 0 configuration is used as the interior routing protocol between the routers, and LDP is up and running on the MPLS network. After recent maintenance work on the MPLS network. IP address 172.16 100 1 cannot access the FTP server with IP address 172.16 192.21 All loopbacks are reachable on the network Which configuration must the engineer apply to correct the problem?

A. Configure passive-interface under the Gi0/2 interface on R22

B. Configure ip ospf network point-to-point under the Lo0 interface on R33

C. Configure network 33.33.10.1 0.0.0.255 area 0 under the OSPF configuration on R33

D. Configure ip cef under the global configuration on R22

Refer to the exhibit.

Routers R1 and R2 are RFC 5036-based MPLS-enabled core routers MPLS IP is enabled globally on both routers OSPF with area 0 configuration is used as an interior routing protocol between the routers After new services were enabled on the MPLS network, LDP connectivity failed on R1 TCP/UDP port 711 is confirmed to be open Which two actions must the engineer take to correct the problem? (Choose two.)

A. Configure network 10.10.140.192 0.0.0.0 arta 0 under the OSPF configuration on R2

B. Configure mpls label protocol Idp under the Gi0/0 interface on R

C. Configure mpls ip under the Gi0'0 interface on R1

D. Configure network 10.10.140.192 0.0.0.255 arta 0 under the OSPF configuration on R2

E. Configure labtl mpls ip protocol tdp under the Gi0 0 interface on R1

Which difference should be considered when intradomain or interdomain multicast routing is implemented?

A. Interdomain multicast routing requires an IS-IS or OSPF neighbor relationship between the domains but intradomain multicast routing requires only BGP

B. Interdomain multicast routing relies on PIM-DM and intradomain multicast routing relies on PIM-SM.

C. interdomain multicast routing uses BIDR-PIM to establish neighbor relationships between AS and interdomain multicast routing uses MSDP

D. A network uses intradomain multicast routing without interdomain routing but networks that use interdomain multicast routing must also apply intradomain routing
