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?

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.

shoud be D
sorry meant C
The ability to create LSP paths with bandwidth reservation
