On router R4, remove the mpls ip command on the s/O/O/2 interface.

On router R2, configure the mpls ip command on the SIO/O/4 interface.

On router R4, configure the mpls label protocol Idp command on all serial interfaces.

On router R2, configure the mpls label protocol Idp command on the interface.

Q75. Refer to the exhibit.

Refer to the exhibit. Customer A is a small media company with two offices connected by a 512 Kbps line. Their NY office is connected to several external partners by static routes on router R3. VoIP services use VoIP codec G729 Users reported poor voice quality and slow data transfer between the offices A network engineer configured ip tcp header-compression iphc-format on R2 and R3 routers Which additional action must the engineer take to fix the issue?

Configure the ip ospf I area O command under Serial 1/1 interfaces on R2 and R3 to avoid routing loops

Change the OSPF router ID on either router so that the router IDs are unique.

Configure the summary-address 10.10.0.0 255.255.240.0 command on R3 to optimize OSPF communication

Configure the BGP routing protocol between R2 and R3 to control route propagation.

Q76.

Refer to the exhibit. Which statement about this configuration is true?

Router 1 sends and receives multiple best paths from neighbor 192.168.1.1

Router 1 sends up to two paths to neighbor 192.168.1.1 for all routes

Router 1 receives up to two paths from neighbor 192.168.1.1 for all routes in the same AS

Router 1 receives only the best path from neighbor 192.168.1.1

Q77. Refer to the exhibit.

An engineer is troubleshooting an OSPF issue. Router 1 has a neighbor relationship with router 2. Only router 1 classful EIGRP routes can be seen on router 2. In order for all EIGRP routes to be redistributed correctly, which action should be taken?

Router 1 must have the keyword subnets included in the redistribution command for all EIGRP routes to be redistributed.

Router 1 must remove the AS number 1 from the redistribution command for all EIGRP routes to be redistributed.

Router 1 must have the keyword ospf-metric included in the redistribution command for all EIGRP routes to be redistributed.

Router 1 must have the keyword metric-type 1 included in the redistribution command for all EIGRP routes to be redistributed.

Q78. Refer to the exhibit.

After troubleshooting BGP traffic steering issue, which action did the network operator take to achieve the correct effect of this configuration?

Routes that have passed through AS 65517 have the local preference set to 150.

Routes that have originated through AS 65517 have the local preference set to 150.

Routes directly attached to AS 65517 have the local preference set to 150.

Routes that have passed through AS 65517 have the local preference set to 150 and the traffic is denied.

Q79. Refer to the exhibits.

A network operator is troubleshooting packet loss seen from the R1 loopback interface to the R2 loopback interface over the core network. The operator is attempting to identify the next leg in the path from PE1. Which interface and label path should the operator investigate next?

PE1 – Gi0/0/0/3 – forwarding label 24002

PE1 – Gi0/0/0/2 – forwarding label 24002

PE1 – Gi0/0/0/3 – forwarding label 24001

PE1 – Gi0/0/0/2 – forwarding label 24001

CE1 and CE2 cannot communicate through the service provider BGP peering is established between PE1 and PE2. IS-IS is the only routing protocol running in the service provider core. What step can be done to troubleshoot the issue?

Switch the IGPs running in the core from IS-IS to OSPF to support a Cisco MPLS TE tunnel from PE1 to PE2.

Configure BGP between CE and PE routers.

Confirm that IS-IS is running with metric-style narrow.

Verify the MPLS LSPs.

Q81. A network engineer is troubleshooting OSPF multiarea. Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?

hierarchical CLI

DR support for topology management

routing process enabled by default on all interfaces

show ip ospf topology command

The two routers cannot authenticate with one another.

The two routers have the same area ID.

The two routers have the same network ID.

The two routers have different IS-types.

Q84. Refer to the exhibit.

After troubleshooting BGP traffic steering issue, which action did the network operator take to achieve the correct effect of this configuration?

Routes that have passed through AS 65517 have the local preference set to 150.

Routes that have originated through AS 65517 have the local preference set to 150.

Routes directly attached to AS 65517 have the local preference set to 150.

Routes that have passed through AS 65517 have the local preference set to 150 and the traffic is denied.
