Exam 200-301 topic 1 question 201 discussion

Desirable/Auto (PAGP) Active/Passive (LACP)

I only see A as the answer because the configuration does the same on both interfaces so if they are both mode Active it will form an LACP channel; which is what is required. If both are auto it will not form, if both are desirable it will form an PAGP channel, which is not what is required, if they are both on there will be no protocol, if they are passive no LACP will form. So the only answer is A.

I take back what I said on a reply about the display output. The (P) next to the interface actually means "in port-channel". I thought it stood for "passive." I was wrong. Here are the Flag codes: 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 So, my final answer A & C. active-passive (or can also do active-active)

A & C are correct

A & C are correct

IT CORRET

It´s A C

As long as at least (I repeat AT LEAST) one states "active", LACP forms. gg good day Go Dodgers

why question has together word? Correct Answer is: A

LACP(vendor natural)form a Ether channel = (Active & Active) / (Active & Passive) / (Passive & Actives) PAgP (CISCO) form a Ether channel = (Desirable & Desirable) / (Desirable & Auto) / (Auto & Desirable)

A and D is right Easy to know if familiar to Etherchannel

The command output given is only for one side of the Etherchannel on the Switch in question (we are not given the details of the other switch, do we have to assume that the other switch ends with the same interfaces and the same Channel-group?) , so option A :" mode Active" ensures that the switch will take the initiative and tries to form the channel. Surely it will result in success as the other end has one of 2 options (active or passive). Of course, assuming that the other end on the other switch is not incorrectly reconfigured using PAgP options (auto/desirable) or the no protocol option (mode on). Theses case results in that the channel is not formed. For Choice C, it does not guarantee Ether-Channel formation as long as we don't have information about which mode the other end is being configured (if Active, channel is formed, if passive, channel is not formed). Requiring 2 answers without having information about the other end is not correct Also, if the 2 has to be used yogether (on the same switch) the second one will replace the first.

If LACP PortChannel B is Passive, then LACP PortChannel A must be Active Or the reverse, A-to-B = Active-to-Passive. (Together, this will work).

Answer - A & C. If you saw PAGP under protocol, in the screenshot, the answer would've been B & D.

PAgP- Disirable/Auto (Link formation) LACP- Active/Active or Active/Passive (Link formation)
