Which of the following statements about the Path Computation Element (PCE) is FALSE?

The PCE can obtain topology and traffic-engineering information from the network using either a link-state IGP or BGP-LS.

A stateful PCE proactively monitors all the existing LSPs and triggers the necessary repairs and re-optimizations.

A stateless PCE can calculate cross-area traffic-engineering-constrained LSP paths.

A stateful PCE can allow LSPs to reserve bandwidth.
