  A. Both LSP-3 and LSP-4 take R1-R2-R4-R6.
  B. Both LSP-3 and LSP-4 take R1-R3-R5-R6.
  C. LSP-3 takes R1-R3-R5-R6 and LSP-4 takes R1-R2-R4-R6.
  D. LSP-3 takes R1-R2-R4-R6 and LSP-4 takes R1-R3-R5-R6.
  E. CSPF randomly chooses one of the equal cost paths for the two LSPs.
  B. Both LSP-3 and LSP-4 take R1-R3-R5-R6.

• Question 48:

  Which of the following statements regarding per-platform label space are true? Choose two answers.

  A. A separate label is used for each interface that the FEC is advertised on.
  B. It uses fewer label resources than a per-interface label space.
  C. It is typically used when the device has ATM or Frame Relay interfaces.
  D. It uses more label resources than a per-interface label space.
  E. A single label may be assigned to an FEC and used across all interfaces of the same router.
  F. It is only valid when the LDP peers are directly connected over an interface, and the label is only going to be used for traffic sent over that interface.
  B. It uses fewer label resources than a per-interface label space.
  E. A single label may be assigned to an FEC and used across all interfaces of the same router.
