Nokia Segment Routing Exam Questions and Answers

Question 1

For any of the LFA methods to work properly, there must be a router in the backup path that will forward traffic addressed to the destination without sending it back to the source. Which of the following statements describes the way R-LFA selects such a router?

Options:

A.

It selects an immediate neighbor.

B.

It selects a remote router, reachable through a tunnel defined by a single Node-SID.

C.

It selects a remote router, reachable through a tunnel defined by a Node-SID and one or two Adjacency-SIDs.

D.

It can select an immediate neighbor or a remote router, as long as the backup path coincides with the path that will become active after IGP reconvergence.

Question 2

Which of the following statements about Segment Routing is FALSE?

Options:

A.

No path signaling is required to establish an SR tunnel.

B.

Intermediate routers do not maintain any tunnel informal

C.

A link-state IGP is required to distribute SID information.

D.

For TE-constrained tunnels, each data packet typically carries a single MPLS label to specify the tunnel path.

Question 3

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?

Options:

A.

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

B.

The ability to create LSP paths with bandwidth reservation

C.

The ability to create LSPs with primary and secondary paths

D.

The ability to ensure that some LSP paths are disjoint

Question 4

Which of the following statements about the Path Computation Element (PCE) is FALSE?

Options:

A.

The PCE can obtain topology and traffic-engineering information from the network using either a link-state IGP or BGP-LS.

B.

A stateful PCE proactively monitors all the existing LSPs and triggers the necessary repairs and re-optimizations.

C.

A stateless PCE can calculate cross-area traffic-engineering-constrained LSP paths.

D.

A stateful PCE can allow LSPs to reserve bandwidth.

Question 5

Which of the following steps is NOT required when configuring IS-IS to support Segment Routing?

Options:

A.

MPLS label range reserved for Segment Routing.

B.

Enable interfaces used for Segment Routing under

C.

The flooding scope of Segment Routing information.

D.

The Segment Routing Global Block range.

Question 6

To create a flex-algo instance in a network, which of the following configuration steps is mandatory?

Options:

A.

Configuring the proper values for the shared-risk link groups (SRLGs) that will define the flex-algo topology.

B.

Configuring at least one router in the network to create and advertise the flex-algo definition.

C.

Specifying whether the LSP paths will be computed locally or by an external path computation element (PCE).

D.

Configuring LSPs between every pair of PE routers.
