Question:
Refer to the exhibit. A network administrator is configuring an EtherChannel between SW1 and SW2. The SW1 configuration is shown. What is the correct configuration for SW2?

• A. interface FastEthernet 0/1
  channel-group 1 mode active
  switchport trunk encapsulation dot1q
  switchport mode trunk
  interface FastEthernet 0/2
  channel-group 1 mode active
  switchport trunk encapsulation dot1q
  switchport mode trunk
• B. interface FastEthernet 0/1
  channel-group 2 mode auto
  switchport trunk encapsulation dot1q
  switchport mode trunk
  interface FastEthernet 0/2
  channel-group 2 mode auto
  switchport trunk encapsulation dot1q
  switchport mode trunk
• C. interface FastEthernet 0/1
  channel-group 1 mode desirable
  switchport trunk encapsulation dot1q
  switchport mode trunk
  interface FastEthernet 0/2
  channel-group 1 mode desirable
  switchport trunk encapsulation dot1q
  switchport mode trunk
• D. interface FastEthernet 0/1
  channel-group 1 mode passive
  switchport trunk encapsulation
  dot1q switchport mode trunk
  interface FastEthernet 0/2
  channel-group 1 mode passive
  switchport trunk encapsulation dot1q
  switchport mode trunk

Explanation:

If the etherchannel was configured with mode "auto", it was using PagP, so, we need to configure the other switch with "desirable" mode.

PagP modes: auto | Desirable
LACP modes: active | pasive
