質問 2

You support a WLAN using dual-band 802.11ac three stream access points. All access points have both the
2.4 GHz and 5 GHz radios enabled and use 40 MHz channels in 5 GHz and 20 MHz channels in 2.4 GHz. A manager is concerned about the fact that each access point is connected using a 1 Gbps Ethernet link. He is concerned that the Ethernet link will not be able to handle the load from the wireless radios. What do you tell him?

（A）His concern is invalid because the AP will compress all data before transmitting it onto the Ethernet link.

（B）His concern is valid and the company should immediately plan to run a second 1 Gbps Ethernet link to each AP.

（C）His concern is valid and the company should upgrade all Ethernet links to 10 Gbps immediately.

（D）Due to 802.11 network operations and the dynamic rates used by devices on the network, the two radios will likely not exceed the 1 Gpbs Ethernet link.
