Refer to the exhibit. Routers RA and RB are IS-IS peers configured for NSF, but router RC is an IS-IS peer without NSF capability. If RA undergoes processor switchover, what is the effect on the network environment?
All peer relationships remain up, but the link-state database is rebuilt on each device
If RC is operating without the Cisco configuration option, all three routers tear down their peering relationships and re-establish peering
All peer relationships remain up and the link-state database is unchanged

Refer to the exhibit. What is the relationship between Router 1 and Router 2?
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
Router 1 and Router 2 are participating in SR-TE tunnels and are both head-end routers
Router 1 and Router 2 centrally learn the topology of the network to aid in SR-TE path selection for peers
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

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?
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?
Configure PE2 to automatically select its own LDP router ID with 192.168.1.1.
Create a targeted LDP session on PE2 to override the missing routing table entry on PE1.
Configure PE1 with a static route to 192.168.1.1.
Enable LDP session protection on the link that P1 uses as the next hop to PE2.

Customer traffic from the branch site to the hub is experiencing packet drops. The engineer verified that:
• Customer traffic from the hub is able to reach the branch site.
• The connection between PE1 and PE2 is working normally.
• Routers P1 and P2 are able to ping devices on the hub site.
Which action resolves the issue?

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

You have configured routing policies on a Cisco IOS XR device with routing policy language. Which two statements about the routing policies are true? (Choose two.)
The routing policies affect BGP-related routes only.
If you make edits to an existing routing policy without pasting the full policy into the CLI, the previous policy is overwritten.
You can change an existing routing policy by editing individual statements.
The routing policies are implemented in a sequential manner.
The routing policies are implemented using route maps.
