You are configuring an EtherChannel between two switches. You check your configuration on the first switch and are ready to configure the second switch. What mode do you need to configure on the other switch?
Refer to the following exhibit.

A. Switch(config-if)#channel-group 1 mode auto
B. Switch(config-if)#channel-group 1 mode desirable
C. Switch(config-if)#channel-group 1 mode active
D. Switch(config-if)#channel-group 1 mode passive

B. Since the auto mode was used on the first switch (Switch A), desirable should be used on the second switch to assure forming of an EtherChannel.
