A) The network is managed by more than one network management system.
B) The control plane is active in some network nodes and not in others.
C) The network manager controls all the routing for the network.
D) Each router has software to run the GMPLS protocols and can modify the node's switching fabric.

2. What is the definition of Constrained Shortest Path First (CSPF)?

A) It is the 5FP algorithm applied after pruning links that do not meet the specified constraints.
B) It is the SPF algorithm applied for low latency LSPs.
C) It is the SPF algorithm applied to low bandwidth LSPs.
D) It is a combination between OSPF-TE and RSVP-TE.

3. What is the purpose of preemption when establishing an LSP?

A) To tear down an existing LSP in order to accommodate higher priority traffic
B) To measure the end-to-end latency
C) To pick the next hop during LSP signalling
D) To assign the correct wavelengths depending on the type of traffic

4. What is the meaning of Generalized in GMPLS?

A) GMPLS can be used for traffic types other than data packets
B) Switching can be based on values other than the label
C) Unlike MPLS, GMPLS supports multi-vendor networks
