This exam tests how well candidates understand segment routing concepts and how to apply them in real network scenarios. It focuses on configuration knowledge, operational verification, traffic engineering, path computation, fast re-route, and flex-algo behavior. Strong candidates should be able to interpret routing objectives, understand how features interact, and troubleshoot practical deployment situations.

Actual Nokia 4A0-116 Exam Questions

Question 1

Which of the following is NOT an advantage of using a PCE for the computation of TE-constrained LSP paths, as compared to using CSPF locally on the PE router?

Correct answer: B

PCE does not have the capability to reserve bandwidth, This is a function of a Resource Reservation Protocol (RSVP) or a Label Distribution Protocol (LDP) and is done locally on the PE.

PCE can have advantages such as:

The ability to create cross-area TE-constrained LSP paths

The ability to create LSPs with primary and secondary paths

The ability to ensure that some LSP paths are disjoint

it can be used to optimize the path computation by centralizing the path calculation and by taking into account a global view of the network.


Question 2

Which of the following statements about primary and secondary SR-TE LSP paths is FALSE?

Correct answer: B

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.


Question 3

Which of the following list of SR-TE attributes has to be advertised among routers?

Correct answer: A

In SR-TE, routers need to advertise certain attributes of their links to other routers in the network in order to calculate traffic-engineered paths. These attributes include:

Administrative groups that each link belongs to: This information is used to restrict the use of certain links to specific traffic types or groups.

TE metric of links: This information is used to calculate the cost of using a particular link for a traffic-engineered path.

Bandwidth availability of each link: This information is used to control the amount of traffic that can be sent over a particular link.

SRLG that each link belongs to: This information is used to avoid routing over the same physical link. Link status up/down is not needed to be advertised as it is part of the IGP protocol and is used to check the reachability of a link.


Question 4

Examine the exhibit. Based upon the configuration, which routers will the LSP go through?

Correct answer: C

Question 5

Which of the following statements about a Segment Routing SID is FALSE?

Correct answer: B

A router advertises its local Node-SID as a local SRGB and an index only if it is configured as an index: This statement is not true, A router will advertise its local Node-SID as a local SRGB and an index, whether it is configured as an index or not.
