Nokia Segment Routing Exam Sample Questions (Q25-Q30):

NEW QUESTION # 25
OSPF type-10 Opaque LSAs can carry different types of advertisements. What type of advertisement carries a router's local 5RGB information?

• A. Traffic Engineering Info
• B. Extended Prefix Info
• C. Router Info
• D. Extended Link Info

Answer: C Explanation:
This type of advertisement carries a router's local SRGB information, which is used to distribute information about the local SID allocation range
NEW QUESTION # 26
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 periodically try to calculate a new path at a rate defined by the resignal timer.
• B. The head end will continue forwarding traffic to the current next-hop indefinitely, and R2 will redirect the traffic to R3 after IGP reconvergence.
• C. The head end will continue forwarding traffic to the current next-hop indefinitely, which will be discarded at the point of failure.
• D. The head end will periodically try to calculate a new path at a rate defined by the retry timer.

Answer: C 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 # 27
Which of the following statements about the operation of seamless-BFD is FALSE?

• A. A seamless-BFD template needs to be configured on the head-end of the LSP.
• B. The routing protocol (OSPF or IS-IS) is used to carry the reflector discriminator information.
• C. Seamless-BFD responses are sent back using the LSP label stack.
• D. To be able to respond to seamless-BFD messages, a router must be configured as a reflector.

Answer: C Explanation:
Seamless-BFD is a mechanism that allows the detection of faults in MPLS LSPs more quickly by using BFD (Bidirectional Forwarding Detection) protocol. Seamless-BFD responses are sent back using the MPLS data-plane, not the LSP label stack.
NEW QUESTION # 28
Which of the following is NOT a valid option to steer traffic into a flex-algo segment-routing tunnel?

• A. Configuring and applying a VSI import policy to an EVPN service and enabling the sr-is-is or sr-ospf tunnel type for the service, depending on the underlying routing protocol.
• B. Configuring and applying a VRF import policy to a VPRN service and enabling the sr-is-is or sr-ospf tunnel type for the service, depending on the underlying routing protocol.
• C. Using a flex-algo Node-SID as an explicit hop in the path definition of an SR-TE LSP and enabling the sr-te tunnel type for a VPN service.
• D. Specifying the flex-algo instance ID as an additional TE constraint for an SR-TE LSP and enabling the sr-te tunnel type for a VPN service.

Answer: A Explanation:
Applying a VSI import policy to an EVPN service and enabling the sr-is-is or sr-ospf tunnel type for the service is not a valid option for steering traffic into a flex-algo segment-routing tunnel, VSI is not related to flex-algo SR.
NEW QUESTION # 29
The exhibit shows the fast re-route configuration on router R1, in which both R-LFA and TI-LFA have been enabled. Assume that there are multiple potential backup paths for a given prefix. Which of the following options will router R1 use?

• A. A D-LFA path that would coincide with the path after IGP re-convergence.
• B. An R-LFA path that would not coincide with the path after IGP re-convergence.
• C. A D-LFA path that would not coincide with the path after IGP re-convergence.
• D. A standard LFA path that would not coincide with the path after IGP re-convergence.

Answer: A Explanation:
The exhibit shows that both R-LFA and TI-LFA have been enabled on router R1. R-LFA (Remote Loop-Free Alternate) is a method that is used to protect the active segment of a tunnel, and it allows the router to find a backup path that coincides with the path that will become active after IGP reconvergence. TI-LFA (Topology Independent LFA) is a method that is used to protect an end-to-end multi-segment tunnel, it allows the router to find a backup path that does not rely on the IGP topology, but on the segment routing topology.
With R-LFA and TI-LFA enabled, router R1 will use a D-LFA (Dual-Loop-Free Alternate) path, which is a combination of both R-LFA and TI-LFA, this path will coincide with the path after IGP re-convergence.
A standard LFA, R-LFA, and D-LFA which do not coincide with the path after IGP re-convergence are not the options.
