Another badly formulated question from NetApp. Chipset VS ASIC chips. ASIC chips gets a lot more attention than chipsets so a question like this becomes confusing in the context of this question...

taken from TR-4182 As a best practice, NetApp recommends that when you create an IFGRP, you should create the IFGRP by using ports from different NICs. You should, however, verify that they are the same model or chipset and that they have the same port speed, functionality, and so on. This step is critical in maintaining consistency in the IFGRP in the event of a port failure. By maintaining consistency with port aggregation and by spreading the IFGRP over NICs in different PCI slots, you decrease the chances of a slot failure bringing down all the ports in an IFGRP.

A and C are the correct answers

A is correct,if we use nics from different NICS,it is better to use the same chipset, IF we use the NICS from the same NIC adapter,its better to use from the different Chipsets. so i go with A and D in the second thought.

A & D - no doubt

I went to the link for TR-4182 that HangLiu posted. Page 12, it specifically states, "In that case, to prevent an ASIC failure from taking down multiple ports within an IFGRP, NetApp recommends that IFGRPs use ports that do not share the same ASIC." So I would say A,C .

should be A C , NetApp recommends that IFGRPs use ports that do not share the same ASIC

A & D :-)
