CCNA: Cisco Certified Network Associate — Question 1161

Which Rapid PVST+ port state does a port operate in without receiving BPDUs from neighbors or updating the address database?

Answer options

• A. listening
• B. forwarding
• C. disabled
• D. blocking

Correct answer: C

Explanation

The correct answer is C, 'disabled', because in this state the port is not actively participating in the network and does not receive BPDUs or update the address database. The other states, such as listening, forwarding, and blocking, involve some level of BPDU processing or address learning, which does not occur in a disabled state.
