Refer to the exhibit.

What is the relationship between Router 1 and Router 2?

A.

Router 1 centrally learns the topology of the network to aid in SR-TE path selection, and Router 2 is a node that feeds Router 1 topology information.

B.

Router 1 and Router 2 are participating in SR-TE tunnels and are both head-end routers.

C.

Router 1 and Router 2 centrally learn the topology of the network to aid in SR-TE path selection for peers.

D.

Router 2 is the head-end router in an SR-TE tunnel, and it is learning topology of the network from the PCE enabled on Router 1.

Refer to the exhibit.

Routers within the cluster are not receiving the desired prefixes. What must be done to fix the issue?

A.

Clients in that cluster must have full mesh connectivity between eBGP peers.

B.

No client-to-client must be disabled.

C.

Clients in that cluster must have full mesh connectivity between iBGP peers.

D.

No client-to-client reflection must be enabled.

Refer to the exhibit. Users connected to an application on 1.1.1.1 via routers CE1 and CE2 are complaining of frequent disconnections. While troubleshooting the issue, a network engineer with an employee ID: 4333:96:916 determined that the application itself is working normally, but the link connected to the 1.1.1.1 application is flapping. The users on CE1 and CE2 are accessing applications on 2.2.2.2 without difficulty. Which action resolves the issue?

A.

Disable split horizon on router R2.

B.

Redistribute CE1 routes on router R2.

C.

Enable passive interface on the router R3 Loopback1 interface.

D.

Enable route dampening on routers R1 and R2

Refer to the exhibit.

An engineer working on a client’s network is trying to solve the BGP community issue on R1 and R2 routers. After displaying the BGP entries, the engineer notices that both routers still have different outputs. Which action must the engineer perform to any of the routers to correct the problem and get the same output?

A.

Execute the Ip bgp-community new-format command in Router1.

B.

Remove the Ip bgp-community new-format command in Router1.

C.

Advertise the route to Router2 as standard community.

D.

Advertise the route to Router2 as extended community.

What is a requirement of PIM-SM?

A.

It requires Cisco Express Forwarding to be enabled.

B.

It must be enabled on loopback interfaces only

C.

It requires OSPF to be configured on the network.

D.

It must use an RP

Which task is performed when troubleshooting LDP?

A.

Execute the ping utility to generate information about the MAC addresses used along the path

B.

Verify that MPLS is disabled globally and enabled on the necessary interfaces in a per-interface basis

C.

Execute the traceroute utility to generate information about the labels used along the path

D.

Verify that Cisco Express Forwarding has been disabled on the network

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

A.

hierarchical CLI

B.

routing process enabled by default on all interfaces

C.

DR support for topology management

D.

show lp ospf topology command

What is one of the purposes of a default Multicast Distribution Tree?

A.

to offload traffic from data MDT

B.

to define the RP for PIM sparse mode and the different leafs

C.

to support control traffic between different VRFs

D.

to handle high-bandwidth source streams

Refer to the exhibit.

While configuring router 2 with all the default values, a network engineer cannot see any route received in router 1. How should the engineer solve the issue?

A.

Set up a priority different than 0 in the interface.

B.

Modify the router ID to be the interface IP on the serial.

C.

Modify the IP address or mask of the interface to a valid one.

D.

Set the network type in S1/0 to point-to-point.

Refer to the exhibit The branch office in area 10 is connected to HQ via Frame Relay uplinks with bandwidth constraints After a recent implementation of QoS on the R2 and R3 networks the system has been logging %SYS-2-MALLOCFAIL: Memory allocation of 65536 bytes failed from 0x224E321, alignment 0 messages To reduce traffic load and memory utilization on R2 and R3 the network engineer configured R1 to announce only one user subnet per location by issuing the summary address 192.168.0.0 255.255.248.0 command en R1 However, the engineer noticed that router R2 still has two routes and a summary address from HQ and R3 also has two routes from HQ Which two actions must the engineer take on R1 to fix the issue so that only one route is announced’ (Choose two.)

A.

Configure the subnet range with the network command under the IS-IS process.

B.

Configure RI as a Level 1 device.

C.

Redistribute both routes into the ISIS process.

D.

Configure a summary route for Level 1-Level 2 devices.

E.

Configure a summary route for Level 1 devices.
