Q466. When you migrate a network from PVST+ to rapid-PVST+, which two features become inactive? (Choose two.) 

A. Root guard 

B. Loop guard 

C. UplinkFast 

D. UDLD 

E. BackboneFast 

F. Bridge Assurance 

Answer: C,E 

Explanation: 

It is good to know the UplinkFast and BackboneFast behavior before you start the migration process. 

Here, the Access1 switch runs Cisco IOS. This output is taken before migration to the rapid-PVST+ mode: 

Access1#show spanning-tree vlan 10

You can see in the show spanning-tree summary command output that UplinkFast and BackboneFast are enabled, but are inactive in rapid-PVST mode.
