Loopfree-alternate has been enabled on a router for its link-state routing protocol. For which types of segments will the router attempt to find a backup path, so that they become protected by fast re-route?

• A.  Only segments defined by an Adjacency-SID.
• B.  Segments defined by a Node-SID and segments defined by an Adjacency-SID.
• C.  No segments, unless segment-routing fast-reroute is also explicitly enabled.
• D.  Only segments defined by a Node-SID.

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

• A.  Only standard LFA is enabled on router R1; fast re-route is not enabled on router R2.
• B.  Standard LFA and remote-LFA are enabled on router R1; standard LFA and TT-LFA are enabled on router R2.
• C.  Only standard LFA is enabled on both routers R1 and R2.
• D.  Standard LFA and remote-LFA are enabled on router R1; fast re-route is not enabled on router R2.

Examine the exhibit. Based upon the configuration, which routers will the LSP go through?

• A.  R1, R3, R2, R5, R4 and R6
• B.  R1, R2, R5 and R6
• C.  R1, R3, R4 and R6
• D.  R1, R2, R4 and R6

Which of the following statements about Segment Routing tunnels is FALSE?

• 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.

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

• A.  One valid flex-algo definition, using te-metric as the link metric and including blue links.
• B.  No valid flex-algo definitions, because of the conflicting parameters.
• C.  One valid flex-algo definition, using delay as the link metric and including green 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.
