CCNA: Cisco Certified Network Associate — Question 544

Which state is bypassed in Rapid PVST+ when PortFast is enabled on a port?

Answer options

• A. blocking
• B. forwarding
• C. learning
• D. discarding

Correct answer: C

Explanation

When PortFast is enabled on a port, it allows the port to transition directly to the forwarding state, bypassing the learning state. The other states, blocking, forwarding, and discarding, are still part of the standard spanning tree process that PortFast aims to accelerate for access ports.
