Refer to the exhibit. Router 1 is connected to router 2 on interface TenGigE0/1. Which interface provides the alternate path to 172.16.200.9/32 when the link between router 1 and router 2 goes down?
A backup path must be statically installed
TenGigE0/2 interface provides the alternate path
A primary path must be manually installed

Refer to the exhibit. R1 is directly connected to R2 and R3. R1 is in BGP AS 123, R2 is in BGP AS 2, and R3 is in BGP AS 3. Assume that there is no connectivity issue between R1, R2 and R1, R3. Which result between BGP peers R1, R2 and R1, R3 is true?
The BGP session does not come up between R1 and R2 and between R1 and R3.
The BGP session comes up between R1 and R2 and between R1 and R3.
The BGP session comes up between R1 and R3, but not between R1 and R2.
The BGP session comes up between R1 and R2, but not between R1 and R3.

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 Gi0/0/0/2 forwarding label 24001
PE1 Gi0/0/0/3 forwarding label 24002
PE1 Gi0/0/0/2 forwarding label 24002
PE1 Gi0/0/0/3 forwarding label 24001

Refer to the exhibit. A network operator is getting the route for 10.11.11 0/24 from two upstream providers on #XR3. The network operator must configure #XR3 to force the 10.11.11.0/24 prefix to route via next hop of 10.0.0.9 as primary when available. Which of these can the operator use the routing policy language for, to enforce this traffic forwarding path?
weight of 0 on the prefix coming from 192.168.0.2
lower local preference on the prefix coming from 192.168.0.2
higher local preference on the prefix coming from 192.168.0.1
weight of 100 on the prefix coming from 192.168.0.1

An engineer is troubleshooting slow performance issues on a customer s network after the last multicast configuration change was applied on it. While checking the running configuration on the router, the engineer notices there are many ip igmp join-group commands applied on several interfaces of the router which caused the high CPU utilization usage. What action must the engineer take to solve this issue?
Configure all router interfaces to be process-switched by increasing the query interval
Remove ip igmp join-group command on all unnecessary interfaces
Remove unnecessary members from the IGMP group
Configure ip igmp static-group command on all interfaces

Refer to the exhibit. An engineer is addressing an IS-IS design issue which is running within the topology. All links are running on FastEthernet, except the link between R5 and R4, which is Gigabit Ethernet. Which statement about the design is true?
R4 prefer to reach R5 using R1 as the next hop
All links have equal cost if the default metric is used
R5 prefers to use R4 as the next hop for all routes
R1 prefer to use R5 as the next hop to reach R4

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.
Routing Protocols
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?

Refer to the exhibit. A network engineer applied configuration on R5 to summarize all OSPF routes, but R4 is still receiving specific routes from R5. The engineer has confirmed that both R5 and R4 routers are configured with correct summarization configuration, but R5 is not sending the summary routes. What action must the engineer take to fix the problem?
Remove summarization configuration on R5 and configure it on R4
Clear link-state database on both R4 and R5 routers for summarization to work
Configure a sham link between R4 and R5 to support summarization within Area 2
Move R4 and R5 in separate areas as now they maintain the same link-state database

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?
The MED attribute can be applied on R2 to influence R1 to use it as the primary path.
The local preference attribute can be applied on R3 to influence AS 65513 to use AS 65515 as the secondary path.
The weight attribute can be applied on R2 to influence AS 65513 to use AS 65515 as the primary path.
The IGP metric can be manipulated on R1 to allow traffic to be load balanced between R2 and R3.
