CCNA: Cisco Certified Network Associate — Question 126

Which two commands can you use to configure an actively negotiate EtherChannel? (Choose two.)

Answer options

• A. channel-group 10 mode on
• B. channel-group 10 mode auto
• C. channel-group 10 mode passive
• D. channel-group 10 mode desirable
• E. channel-group 10 mode active

Correct answer: D, E

Explanation

The correct answers are D and E because 'channel-group 10 mode desirable' and 'channel-group 10 mode active' both enable active negotiation of the EtherChannel using the Port Aggregation Protocol (PAgP) and Link Aggregation Control Protocol (LACP) respectively. The other options either do not negotiate (A, B) or are in a passive mode (C), which does not initiate negotiation.
