Nokia Segment Routing Exam Sample Questions (Q14-Q19):

NEW QUESTION # 14
An SR-TE LSP with a path definition that includes router R4 as a loose hop and for which Seamless-BFD has been enabled is following the path shown in the exhibit. What happens after router R4 fails if the routers along the path follow the default behavior?

• A. The head end will continue forwarding traffic to the current next-hop indefinitely, and R2 will redirect the traffic to R3 after IGP reconvergence.
• B. The head end will periodically try to calculate a new path at a rate defined by the resignal timer.
• C. The head end will periodically try to calculate a new path at a rate defined by the retry timer.
• D. The head end will continue forwarding traffic to the current next-hop indefinitely, which will be discarded at the point of failure.

Answer: D Explanation:
When an SR-TE LSP with Seamless-BFD enabled, the BFD sessions are established between the routers along the path to detect any failures quickly. If a failure happens in the path, the router will stop forwarding the traffic and send a BFD control packet to the head-end router. In this case, R4 failed, BFD sessions will detect the failure and send a message to the head-end router, but since R4 is a loose hop, the path doesn't have to be re-calculate. The head-end router will continue forwarding traffic to the current next-hop, R2, which will be discarded at the point of failure (R4) as it doesn't know about the failure. And the traffic will not be redirected to R3 after IGP reconvergence.
NEW QUESTION # 15
For any of the LFA methods to work properly, there must be a router in the backup path that will forward traffic addressed to the destination without sending it back to the source. Which of the following statements describes the way R-LFA selects such a router?

• A. It can select an immediate neighbor or a remote router, as long as the backup path coincides with the path that will become active after IGP reconvergence.
• B. It selects an immediate neighbor.
• C. It selects a remote router, reachable through a tunnel defined by a single Node-SID.
• D. It selects a remote router, reachable through a tunnel defined by a Node-SID and one or two Adjacency-SIDs.

Answer: A Explanation:
R-LFA (Remote Loop-Free Alternate) is a method that can select either an immediate neighbor or a remote router to be used as a backup next hop, as long as the backup path coincides with the path that will become active after IGP reconvergence.
NEW QUESTION # 16
Which of the following statements about primary and secondary SR-TE LSP paths is FALSE?

• A. Preference values can be configured for non-standby secondary paths.
• B. The primary path is always preferred over a secondary pa
• C. Only one LSP path forwards the traffic at any time,
• D. Up to three paths can be configured for a given SR-TE LS

Answer: D Explanation:
Typically, in SR-TE, only two paths can be configured for a given SR-TE LSP: primary path and secondary path. The primary path is used for normal traffic forwarding, and the secondary path is used as a backup in case the primary path fails. Only one LSP path forwards the traffic at any time.
NEW QUESTION # 17
Based on the exhibit, and given that the system IP address of router RIO is 10.10.10.10, which of the following statements is FALSE?

• A. Router Rl participates in at least two flex-algo instances.
• B. The underlying routing protocol being used in the network for segment routing is IS-IS.
• C. The Node-SID assigned to router RIO for flex-algo instance 129 is 524338.
• D. Router RIO participates in flex-algo instance 130.

Answer: C
NEW QUESTION # 18
The exhibit highlights in blue the primary path of a segment going from router S to router D.
The exhibit also shows a backup path. The protected link fails and fast re-route is triggered on router S. If the backup path has been calculated using standard LFA, how many SIDs are included in the label stack of the data packet forwarded to router R1?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: C
