Which of the following statements about the Path Computation Element (PCE) is FALSE?
A . The PCE can obtain topology and traffic-engineering information from the network using either a link-state IGP or BGP-LS.
B. A stateful PCE proactively monitors all the existing LSPs and triggers the necessary repairs and re-optimizations.
C. A stateless PCE can calculate cross-area traffic-engineering-constrained LSP paths.
D. A stateful PCE can allow LSPs to reserve bandwidth.

Answer: D

Explanation:

Stateful PCE can monitor the existing LSPs and trigger necessary repairs and re-optimizations, but it does not have the capability to reserve bandwidth.
