What statement is false?

A.
A topology change triggers PTSE flooding

B.
For PNNI routing, QoS and link resources are significant

C.
PNNI Signaling is based on UNI 3.0

D.
PNNI signaling uses information from PNNI routing

Explanation:
Once database synchronization has occurred, further topology changes must be distributed throughout the network. PNNI does this by exchanging PNNI Topology State Packets (PTSPs), which contain one or more PNNI Topology State Elements (PTSEs). PTSPs are disseminated using a flooding mechanism and ensure that the network is updated when significant changes occur.
