Nokia Segment Routing Exam Questions and Answers

Question 1

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?

Options:

A.

1

B.

2

C.

3

D.

4

Question 2

Which of the following statements about SR-TE administrative constraints is FALSE?

Options:

A.

A strict hop must be adjacent to the previous hop in the list.

B.

The TE metric for a link is by default the same as the IGP metric.

C.

Shared-Risk-Link Groups are only taken into account when calculating the secondary path.

D.

The head-end router may calculate a path that takes into account max hop count and bandwidth constraints.

Question 3

Based on the configuration shown for routers R1 and R10, what valid flex-algo definitions exist in the network?

Options:

A.

No valid flex-algo definitions, because of the conflicting parameters.

B.

One valid flex-algo definition, using delay as the link metric and including green links.

C.

One valid flex-algo definition, using te-metric as the link metric and including blue links.

D.

Two valid flex-algo definitions, one uses te-metric as the link metric and includes blue links and the other uses delay as the link met includes green links.

Question 4

Examine the exhibit.

An LSP is being configured to start at R1and end at R6 using local CSPF. The LSP has the following constraints. Include admin-group GREEN, use the TE metric and hop-limit 3. What routers will be included in the LSP path?

Options:

A.

R1, R2, R4, R6

B.

R1, R5, R6

C.

R1, R3, R5, R6

D.

R1, R6

Question 5

Which of the following is NOT one of the main goals of traffic engineering?

Options:

A.

Utilizing redundant links.

B.

Avoiding potential congestion points in the network.

C.

Defining traffic paths based on various constraints.

D.

Using the shortest possible path through the network to the destination.

Question 6

Based on the exhibit, which of the following is a viable option for the Path Computation Element (PCE) to obtain all the necessary topology and traffic-engineering information from the network, so that it can calculate LSP paths on behalf of the PE routers?

Options:

A.

Establishing an IGP adjacency with router R2

B.

Establishing IGP adjacencies with routers R1 and R2

C.

Establishing a BGP session using the BGP-LS address family with router R3

D.

Establishing BGP sessions using the BGP-LS address family with routers R3 and R4
