Which task do you perform to begin troubleshooting the problem?

QUESTION 88
Refer to the exhibit.


VPN users that are connected to PE routers are facing network issues. Traffic that originates from CE1 drops before reaching CE2. An engineer finds no outgoing traffic statistics on PE1 and PE2 routers toward CE devices and finds that the PE1 router is running the older software image. Which action must be implemented to resolve the issues?

QUESTION 89
Refer to the exhibit. XR1 and XR2 are sending the prefix 10.11.11.0/24 to XR3.
A configured policy on XR1 is incorrectly prepending AS path 11 11 12 12 onto this prefix.
A network operator wants to add a policy onto XR3 that will not allow the falsely prepending prefix from being installed.
Which policy configuration applied to the XR3 neighbor configuration for XR1 can accomplish this requirement without impact to other or future received routes?

QUESTION 90
Refer to the exhibit.

A network engineer has divided AS into confederations. Due to repeated ASN, when the 10.0 0.0/8 prefix from R1 arrives to R2, BGP automatically rejects it. What should the engineer do to fix the problem so that BGP allows that prefix on R2?

QUESTION 91

Refer to the exhibit. Which effect of this configuration is true?

QUESTION 92
Refer to the exhibit.

A network operator is working to deploy a Unified BGP design and allow it to be available only in selected markets and services in the future. The label allocation is not functioning as desired. Which action will fix the issue?

QUESTION 93
Refer to the exhibit

Which router does R1 install as an alternate next hop when trying to reach R3 if LFA is enabled?

QUESTION 94
Refer to the exhibit. Router 1 has attempted to establish a Cisco MPLS TE tunnel to router 2, but the tunnel has failed.
Which statement about this configuration is true?

QUESTION 95

Topology

Tasks
Configure and verify an OSPF neighbor adjacency between R1 and R2 in OSPF area 0 according to the topology to achieve these goals:
1. R1 pings the Loopback0 interface of R2. Use interface-level configuration to complete this task.
2. R2 pings the Loopback0 interface of R1. Use interface-level configuration to complete this task.
3. R2 receives a single summary route 172.16.100.0/22 for networks 172.16.100.0/24,
172.16.101.0/24, and 172.16.103.0/24.

QUESTION 96
Refer to the exhibit. A network engineer is configuring router R3 to handle multicast streams, but Host-2 cannot send subscription messages to the IPTV source. Which configuration must the engineer apply to router R3 so it passes the IPTV stream to Host-2?

QUESTION 97
Refer to the exhibit.

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?

QUESTION 98
Refer to the exhibit.

The green policy is designed with low delay, and the pink policy is designed with low cost. What is the next hop for node A on its way to node D, with the objective of achieving a low delay?

QUESTION 99
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.

QUESTION 100
For which reason can two devices fail to establish an OSPF neighbor relationship?

QUESTION 101
What is the difference between a source tree and a shared tree in a multicast environment?

QUESTION 102
Refer to the exhibit. Customers A and C are experiencing packet drops when connecting to the application server. While troubleshooting the problem, the network engineer confines that the IS- IS Level-1/2 adjacency is up between routers A, B, C, and D and both customers can communicate with the database server without packet loss. Which action must the engineer take to resolve the issue?

QUESTION 103
Refer to the exhibit. VPN users that are connected to PE routers are facing network issues.
Traffic that originates from CE1 drops before reaching CE2. An engineer finds no outgoing traffic statistics on PE1 and PE2 routers toward CE devices and finds that the PE1 router is running the older software image. Which action must be implemented to resolve the issues?
