Question 1

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?

Options:

A.

The TE information will be advertised for all the OSPF links that have MPLS enabled.

B.

The TE information will only be advertised using application-specific sub-TLVs.

C.

The TE information will only be advertised for the OSPF links that have both MPLS and RSVP enabled.

D.

The TE information will only be advertised using extended-link opaque LSAs.

Question 2

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

Options:

A.

Administrative groups that each link belongs to, TE metric of links, bandwidth availability of each link, SRLG that each link belongs to.

B.

Administrative groups that each link belongs to, TE metric of links, SRLG that each link belongs to.

C.

Administrative groups that each link belongs to, TE metric of links, bandwidth availability of each link, SRLG that each link belongs to, link status up/down.

D.

Administrative groups that each link belongs to, TE metric of links, SRLG that each link belongs to, link status up/down.

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

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

Options:

A.

Only standard LFA is enabled on router R1; fast re-route is not enabled on router R2.

B.

Only standard LFA is enabled on both routers R1 and R2.

C.

Standard LFA and remote-LFA are enabled on router R1; fast re-route is not enabled on router R2.

D.

Standard LFA and remote-LFA are enabled on router R1; standard LFA and TT-LFA are enabled on router R2.

Question 5

The exhibit presents packets being transmitted inside an LSP's multi-segment primary path going from router R1 to router R8. The LSP also has a standby secondary path, and Seamless-BFD has been enabled on the primary path. The link between routers R1 and R2 fails, and fast re-route (FRR) is triggered. As a result, router R1 forwards the packets to router R3 and adds the proper FRR encapsulation to reach which router?

Options:

A.

To reach router R2, which is the LSP's intended next-hop.

B.

To reach router R5, which is the shortest way to go back to the original path.

C.

To reach router R4, which is the tail-end of the active segment.

D.

To reach router R8, which is the tail-end of the LSP.

Question 6

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

Options:

A.

A local Node-SID can be configured directly as an MPLS label.

B.

A router advertises its local Node-SID as a local SRGB and an index only if it is configured as an index.

C.

All routers do NOT need to have the same SRGB range configured.

D.

A local Node-SID can be configured as an index.
