CCNA: Cisco Certified Network Associate — Question 169

When configuring an EtherChannel bundle, which mode enables LACP only if a LACP device is detected?

Answer options

• A. Passive
• B. Desirable
• C. On
• D. Auto
• E. Active

Correct answer: A

Explanation

The correct answer is A (Passive) because this mode waits for a LACP device to be detected before activating LACP. The other modes, like Active, initiate LACP negotiation regardless of whether another LACP device is present, while On does not use LACP at all.
