CCNA: Cisco Certified Network Associate — Question 1300

Which command entered on a switch configured with Rapid PVST+ listens and learns for a specific time period?

Answer options

• A. switch(config)#spanning-tree vlan 1 priority 4096
• B. switch(config)#spanning-tree vlan 1 hello-time 10
• C. switch(config)#spanning-tree vlan 1 max-age 6
• D. switch(config)#spanning-tree vlan 1 forward-time 20

Correct answer: D

Explanation

The correct answer is D, as the 'forward-time' command specifies the time the switch should listen and learn before transitioning to the forwarding state. Option A adjusts the priority, option B sets the hello time, and option C defines the maximum age of received BPDUs, but none of these control the listening and learning duration.
