What security benefit is gained from enabling BPDU guard on PortFast enabled interfaces?
- preventing rogue switches from being added to the network
- protecting against Layer 2 loops
- enforcing the placement of root bridges
- preventing buffer overflow attacks
Answers Explanation & Hints:
BPDU guard immediately error-disables a port that receives a BPDU. This prevents rogue switches from being added to the network. BPDU guard should only be applied to all end-user ports.
