4A0-116 Exam - Question 27


Which of the following is NOT an advantage of using a PCE for the computation of TE-constrained LSP paths, as compared to using CSPF locally on the PE router?

Show Answer
Correct Answer: C

The ability to create LSPs with primary and secondary paths can be achieved without the use of a Path Computation Element (PCE), and can be done directly on the PE router using Constrained Shortest Path First (CSPF). A PCE is typically used for more complex routing decisions, such as creating cross-area TE-constrained LSP paths, ensuring some LSP paths are disjoint, or making sophisticated bandwidth reservations. Therefore, creating LSPs with primary and secondary paths is not an exclusive advantage of using a PCE.

C is the least true as this is not really an advantage of PCE. This can be done with or without a PCE, the others cannot.
