Exam 200-301 topic 1 question 208 discussion

"A" ---- Answer given is correct. Actually a good question since this verifies the knowledge of how LACP works - remember a channel in Passive "wants" to be part of a channel but will sit and wait and only bind if the other end is "Active". I think of "Passive" as follow the leader and "active" as the "do what I say" bully config.

The wording is a bit obfuscating. I keep rereading it and feeling like depending on how you perceive the wording, both A and E could be correct.

it´s A

"active —Enables LACP only if a LACP device is detected."

The only way passive will work is if the other switch is labeled active. It's that simple. gg good day Go Dodgers

I think the wording of the question is weird but the reason it’s passive is because the question ask which mode will only activate lacp if it dectects lacp which is passive. Passive in a way listens to what it’s being told

The question is not clear

A is correct

passive Enable LACP only if a LACP device is detected. This is how the passive is described

From Packet Tracer Switch(config-if-range)#channel-group 1 mode ? active Enable LACP unconditionally auto Enable PAgP only if a PAgP device is detected desirable Enable PAgP unconditionally on Enable Etherchannel only passive Enable LACP only if a LACP device is detected

The question is not really clear. The next question will be how a LACP device is detected? Is it because the remote device sent a LACPdu? Or the local device sent it and the remote respond it?

LACP packets are exchanged between ports in these modes: •Active—Places a port into an active negotiating state, in which the port initiates negotiations with remote ports by sending LACP packets. •Passive—Places a port into a passive negotiating state, in which the port responds to LACP packets it receives but does not initiate LACP negotiation. In this mode, the port channel group attaches the interface to the bundle. https://www.cisco.com/c/en/us/td/docs/ios/12_2sb/feature/guide/gigeth.html

lets say the other side is either active or passive. doesnt matter, but putting the opposite side as Active will always make the etherchannel. (as long as the other side is active or passive) active is the best answer.

LACP ACTIVE PASSIVE, IN THE QUESTION ONE IS DETECTED SO IT IS ACTIVE SO OTHER SHOULD BE PASSIVE

A is correct

Switch(config-if-range)#channel-group 1 mode ? active Enable LACP unconditionally auto Enable PAgP only if a PAgP device is detected desirable Enable PAgP unconditionally on Enable Etherchannel only passive Enable LACP only if a LACP device is detected the question is taken from the switch explanation above i think the answer should me active but i will go with passive

The correct answer should be E..."Active"
