Which of the following statements about the Path Computation Element (PCE) is FALSE?
Which of the following statements about the Path Computation Element (PCE) is FALSE?
A stateful PCE indeed monitors and can trigger repairs and optimizations, but it requires configuration to do so, making the statement that it does this proactively incorrect. Stateful PCEs can allow LSPs to reserve bandwidth, a stateless PCE can calculate cross-area LSP paths, and the PCE can obtain topology information from link-state IGP or BGP-LS, making these statements true.
A stateful PCE can proactively monitor and re-signal LSPs but that is something that has to be configured on the PCC. PCE can be active or passive which makes B is the most false or least true answer.
Stateless PCEs can calculate inter-area LSPs
