1. B is a valid answer . port channel summary command does show if Protocol : LACP is in use on a device.

   This example shows how to display summary information about EtherChannels:

   switch# show port-channel summary

   Flags: D – Down P – Up in port-channel (members) I – Individual H – Hot-standby (LACP only)
   s – Suspended r – Module-removed S – Switched R – Routed U – Up (port-channel)
   Group Port- Type Protocol Member Ports

   Channel

   Eth1/4(P) Eth1/21(P) Eth1/22(P)

2. This answer is wrong. The right answer is A

   Switch#show etherchannel 1 summary
   Flags: D – down P – in port-channel
   I – stand-alone s – suspended
   H – Hot-standby (LACP only)
   R – Layer3 S – Layer2
   U – in use f – failed to allocate aggregator
   u – unsuitable for bundling
   w – waiting to be aggregated
   d – default port

   Number of channel-groups in use: 1
   Number of aggregators: 1

   Group Port-channel Protocol Ports

   1. it’s is not totally wrong, show port-channel summary works in Nexus switches which runs nxos but for this test the correct answer is option A, show etherchannel which works on IOS.
