Which option is a benefit of using Link Aggregation?

A.
The controller participates in trunk negotiation using LACP or the PaGP trunk negotiation
protocol with the Ethernet switch on its links.

B.
Wired Ethernet frames can be fragmented and those fragments are sent simultaneously over
multiple Ethernet links between the controller and the Ethernet switch, which provides the same
improvement in data rate as 802.11n spatial streams provide for wireless traffic.

C.
If a link in a LAG fails, the controller switches traffic for that link over to the remaining link(s) in
less than a second.

D.
A LAG allows the controller to be directly connected to other controllers, which eliminates the
need for Ethernet switches.
