• Question 68:

  Which of the following about Link TLVs found inside Type 10 Opaque LSAs is FALSE?

  A. Link TLVs are used to advertise administrative group information.
  B. Link TLVs are exchanged once RSVP is enabled on the interfaces.

• Question 69:

  Click on the exhibit.

  

  Initially, all links along the path R1-R2-R4-R6 have 400Mbps unreserved bandwidth and all links along the path R1-R3-R5-R6 have 800Mbps unreserved bandwidth. Shared Explicit reservation style is used and Make-Before-Break is enabled. Both fully loose LSPs have been signaled as shown. Later, the configured bandwidth for LSP-1 is changed to 400Mbps. Which of the following is TRUE?

  A. After a new path for LSP-1 is established on R1-R3-R5-R6, the old path is torn down.
  B. After the old path for LSP-1 is torn down, the new path is established on R1-R3-R5-R6.
  C. LSP-1 will stay on R1-R2-R4-R6 because there is enough bandwidth on the existing path.
  D. LSP-1 will be torn down because CSPF fails to find a new path.
  C. LSP-1 will stay on R1-R2-R4-R6 because there is enough bandwidth on the existing path.
