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

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

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

D. A stateful PCE can allow LSPs to reserve bandwidth.

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

B. Establishing an IGP adjacency with router R2

C. Establishing IGP adjacencies with routers R1 and R2

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

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

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

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

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

A. A Segment Routing tunnel can be defined by multiple Node-SIDs.

B. For a Segment Routing tunnel, an intermediate router will always forward the packet based on the best IGP path.

C. A Segment Routing tunnel can be defined by a combination of Node-SIDs and Adjacency-SIDs.

D. A Segment Routing tunnel defined by a Node-SID uses the shortest IGP Path.

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

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

C. 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.

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