Nokia 4A0-116 Exam FAQs
The Nokia Segment Routing exam (exam code 4A0-116) is the official Nokia exam that leads to the Nokia Service Routing Architect certification, sitting at the Elective (within Service Routing Architect Certification) level of the Nokia certification track. It is also connected with Nokia Service Routing Architect. If this is the credential you are working toward, the 42 practice questions at Actual4Cert map directly to its objectives.
The Nokia Segment Routing exam includes 40 questions, and you have 90 minutes to complete them. Divide the time limit by the question count and you get a tight average pace per item, so train yourself to flag time-consuming questions and return to them later instead of getting stuck. Before test day, run at least one full timed session in the Actual4Cert test engine under the same limits — the clock should never surprise you.
According to Nokia, candidates should meet the following before registering: None (no mandatory prerequisites). Requirements can change, so confirm the latest details on the official exam page before you register.

There is no limit on the number of computers you can install it on.
The Nokia Segment Routing blueprint is divided into 6 major domains, starting with Flexible Algorithms (Flex-Algo), Segment Routing Traffic Engineering, and Basic Segment Routing Configuration & Operation. The full breakdown, including every subdomain and its weighting, is listed in the Exam Topics section above — review it against your own weak areas before scheduling the exam.
Nokia Segment Routing Sample Questions:
Question 1
Which of the following is NOT a valid option to steer traffic into a flex-algo segment-routing tunnel?
A. 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.
B. 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.
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.
Question 2
Which of the following statements about Segment Routing tunnels is FALSE?
A. A Segment Routing tunnel can be defined by a combination of Node-SIDs and Adjacency-SIDs.
B. A Segment Routing tunnel defined by a Node-SID uses the shortest IGP Path.
C. For a Segment Routing tunnel, an intermediate router will always forward the packet based on the best IGP path.
D. A Segment Routing tunnel can be defined by multiple Node-SIDs.
Question 3
Examine the exhibit. Based upon the configuration, which routers will the LSP go through?
A. R1, R2, R5 and R6
B. R1, R2, R4 and R6
C. R1, R3, R4 and R6
D. R1, R3, R2, R5, R4 and R6
Question 4
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 standard LFA path that would not 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 D-LFA path that would coincide with the path after IGP re-convergence.
Question 5
The exhibit presents packets being transmitted inside an LSP's multi-segment primary path going from router R1 to router R8. The LSP also has a standby secondary path, and Seamless-BFD has been enabled on the primary path. The link between routers R1 and R2 fails, and fast re-route (FRR) is triggered. As a result, router R1 forwards the packets to router R3 and adds the proper FRR encapsulation to reach which router?
A. To reach router R2, which is the LSP's intended next-hop.
B. To reach router R4, which is the tail-end of the active segment.
C. To reach router R8, which is the tail-end of the LSP.
D. To reach router R5, which is the shortest way to go back to the original path.
