A. RIPv2-TE
B. CSPF
C. OSPF-TE
D. ISIS-TE
E. RSVP-TE
Which of the following commands is used to display the database containing the OSPF-TE LSAs?
A. show router ospf opaque-database
B. show router ospf database
C. show router ospf opaque-Isa
D. show router ospf te opaque
Which of the following describes what happens when facility backup fast reroute is enabled for a LSP? Choose three answers.
A. Each PLR will signal a bypass tunnel that avoids the next-hop node or link.
B. When a failure occurs, the PLR will push an additional label onto the label stack and start forwarding traffic onto its bypass tunnel.
C. The ingress router will include a RRO object in the path message to indicate the routers that should be PLRs and MPs along the protected path.
D. The ingress router will set the local protection desired flag in the session attribute object of the path message to inform all routers along the protected LSP path to establish bypass tunnels.
E. When the bypass tunnel is in use, the MP will include the RRO object in its PathErr message, with the local protection in use flag set to notify the ingress router that it is using the bypass tunnel.

Which of the following about LDP-over-RSVP is TRUE?

C. R1-R2 will have 600Mbps left and R2-R4 will have 600Mbps left.
D. R1-R2 will have 300Mbps left and R2-R4 will have 600Mbps left.
Which of the following is NOT a characteristic of MPLS?

B. It provides a mechanism to engineer network traffic patterns independently of IP routing tables.
C. It will work over most physical layer protocols.
D. It can use GRE tunnels to transport data from many different protocols over an IP network.
