I recently passed the Nokia Certified Nokia Segment Routing exam, and flex algo was the section that benefited most from slow reading and repetition. Once I understood how the constraints translate into algorithm behavior, the questions became much more predictable.

Segment routing fast re route often appears as problem solving where you must pick the correct backup mechanism and predict repair SID stacks under node or link failures, which is easy to get wrong without hands on. A colleague cleared the exam by drilling FRR scenarios, understanding repair path selection and where remote versus local repairs apply.

I passed on my first attempt, and the fast re route section was more nuanced than I expected because it mixes protection concepts with SR specifics. I had better results once I tested failure cases in a lab and watched how traffic shifted under different link and node events.

SR-TE with a path computation element questions can be the most subtle because they test PCEP message roles, stateful PCE behavior and how computed paths are installed, often using trace outputs to diagnose mismatches. I passed after studying PCEP interactions, stateful versus stateless operation, and practicing interpretations of PCE logs.

I managed to pass 4A0-116 after finally getting comfortable with PCE driven SR TE workflows and what changes between local computation and delegated control. Practicing the sequence of configuration and verifying state with the right commands saved me during the scenario questions.

Segment routing tunnels with traffic engineering constraints tend to use scenario questions that require selecting the right constraint combination and ordering for bandwidth and affinity, not just syntax. One candidate I know managed to pass and thanks Pass4Success for providing a good collection of exam questions that let them practice those constraint cases quickly.

I passed the Nokia Segment Routing exam by spending extra time on SR TE constraints, especially how affinities and metrics actually steer the tunnel in a real topology. What tripped me up was keeping candidate paths and policies straight, so I made a one page mapping before test day.

Basic segment routing configuration questions often present a broken forwarding scenario and ask which configuration line or label is missing, so lab time is crucial to recognize common CLI pitfalls. I passed by building SR topologies in a lab and memorizing the key show commands to verify SID bindings and adjacency SIDs.

Introduction to segment routing showed up as conceptual questions where you must identify node versus adjacency versus service SIDs and explain how the SR header steers traffic, which can be tricky under time pressure. A classmate passed the exam after focusing on SID types and packet processing examples and recommends walking through packet flows end to end.

Free Nokia 4A0-116 Exam Actual Questions

Note: Premium Questions for 4A0-116 were last updated On Oct. 04, 2026 (see below)

Question #1

Which of the following statements about Multi-Protocol Label Switching networks is FALSE?

Reveal Solution Hide Solution
Correct Answer: D

The data is transparently carried from end to end: This statement is not true, MPLS does not provide data transparency, which means that the data is not carried unmodified from end to end. MPLS uses labels to forward data, so the original IP packets are encapsulated in new MPLS packets, and the original IP headers are not visible at the egress LSR.


Question #2

Based on the exhibit, which of the following statements about fast re-route for flex-algo instance 129 is TRUE?

Reveal Solution Hide Solution
Correct Answer: C

Question #3

Which option best statements about path definitions is FALSE?

Reveal Solution Hide Solution
Correct Answer: C

Question #4

Which of the following statements about path definitions is FALSE?

Reveal Solution Hide Solution
Correct Answer: C

Question #5

In the context of a network that includes a Path Computation Element (PCE), what is a PCC-initiated LSP?

Reveal Solution Hide Solution
Correct Answer: D

A PCC-initiated LSP is an LSP that is established and controlled by the PCC (Path Computation Client) which is typically a head-end router. The PCC sends LSP setup and teardown requests to the PCE and also reports the existence and state of the LSPs to the PCE. The PCE then uses this information to perform path computation and to monitor the state of the LSPs.
