Free Nokia 4A0-116 Exam Dumps Questions & Answers

Based upon the exhibit, which of the following statements regarding the configuration is FALSE?

• A.Traffic engineering has been enabled on this router.
• B.Traffic engineering information will only be advertised for the interfaces that have both MPLS and RSVP enabled.
• C.Adjacency-SID labels will not be advertised as they have not been defined under the physical interfaces.
• D.The Node-SID assigned to this router is the second label in the defined range.

OSPF is being used for segment routing with traffic-engineering (SR-TE). The traffic-engineering option has been set to "sr-te false". Which of the following statements is TRUE?

• A.The TE information will only be advertised using application-specific sub-TLVs.
• B.The TE information will only be advertised using extended-link opaque LSAs.
• C.The TE information will be advertised for all the OSPF links that have MPLS enabled.
• D.The TE information will only be advertised for the OSPF links that have both MPLS and RSVP enabled.

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.1
• B.4
• C.3
• D.2

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

When OSPF is used to support Segment Routing, the first byte of the link-state ID associated with each of the opaque LSAs indicates the type of information being advertised. Which of the following associations between the first-byte value and its meaning is FALSE?

• A.Value 4 - Router Info
• B.Value 7 - SRGB Range
• C.Value 8 - Extended Link Info
• D.Value 1 - Traffic Engineering
