B. Admin groups can be configured using the command "configure>router>mpls>admingroup".

C. CSPF uses the information defined by admin groups when paths are computed for constraint-based LSPs.

D. By default, interfaces for which MPLS has been enabled are in the default admin group.

A. The router will switch to Path-2 because it is the first secondary path configured in the list.

B. The router will not switch to Path-2 because the router will not revert to another secondary path.

C. The router will not switch to Path-2 because the current path has the longest uptime.

D. The router will switch to Path-2 because it is a more preferred path.

A. Conservative label retention mode

B. Liberal label retention mode

C. Independent control mode

D. Ordered control mode

A. A mechanism that allows RSVP or LDP signaling to use a route other than the IGP best route to establish a LSP.

B. A mechanism that implements opaque LSAs.

C. A mechanism that computes routes based on defined user requirements.

D. A mechanism that allows the IGP shortest path to be used.

A. The router does not have a route to reach to the peer 10.10.10.2/32.

B. The router does not have a route to reach to the prefix 192.10.1.2/32.

C. The router does not have an export policy defined to export the prefix 192.10.1.2/32 into LDP.

D. The router receives an invalid label for the prefix 192.10.1.2/32 from its peer.

A. It results in forwarding based on the next packet header.

B. It indicates that the label is the top of the MPLS label stack.

C. It indicates that the label is the bottom of the MPLS label stack.

D. Any LSR that receives an S bit set to 1 must discard the packet.

C. Node protection tunnels are only used by one-to-one Fast Reroute.

D. Node protection tunnels detour around a failed next downstream router.
