質問 6

ABC Company is planning to install a new 802.11ac WLAN, but wants to upgrade its wired infrastructure first to provide the best user experience possible. ABC Company has hired you to perform the RF site survey. During the interview with the network manager, you are told that the new Ethernet edge switches will support VoIP phones and 802.11 access points, both using
802.3 PoE.
After hearing this information, what immediate concerns do you note?

（A）The power budget in the edge switches must be carefully planned and monitored based on the number of supported PoE devices.

（B）The edge Ethernet switches should support Ether-channel to get the best results out of the network.

（C）If the switches are in optimal locations for VoIP phones, they are likely to be suboptimal locations for 802.11 APs

（D）VoIP phones and 802.11 access points should not be powered by the same edge switch due to distortion.

質問 7

Three access points are used within a facility. One access point is on channel 11 and the other two are on channel 1. The two access points using channel 1 are on either side of the access point using channel 11 and sufficiently apart so that they do not interfere each other when they transmit frames. Assuming no other Aps are in the vicinity, is CCI still a possibility in this network and why?

（A）Yes, because channel 11 loops around and causes CCI with channel 1

（B）No, because the Aps are far enough apart that no CCI will occur

（C）Yes, because the client devices connected to one of the channel 1 APs will transmit frames that reach the other channel 1 AP as well as

（D）No, because CCI only occurs in the 5 GHz frequency band

質問 8

What factors does not influence the distance at which an RF signal can be effectively received?

（A）Transmitting station's output power

（B）Receiving station's output power

（C）Free Space Path Loss

（D）Receiving station's radio sensitivity

（B）WIPS

（C）RBAC

（D）IPSec

（E）SNMP

（F）WPA2

正解：C 解答を投票する
