NEW QUESTION # 143
Using a SCA means that all APs will be using the same channel in a given layer. How is the AP with which the client associates determined?
Response:
- A. All APs share a virtual BSSID. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
- B. All APs share a virtual IP address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
- C. All APs share a virtual Multicast Address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
- D. The client selects the AP based on a known set of MAC to BSSID mappings stored in the clients authorized SSID listing.

NEW QUESTION # 147
What statement is true of a WLAN design that supports Real-Time Location Services (RTLS) with 802.11 RFID asset tags?
- A. When passive tags are implemented, the AP density should be increased by 25% to make up for the shorter transmit range of passive tags as compared to active tags.
- B. Active RFID tags periodically transmit 802.11 beacon management frames that must be synchronized with the AP for proper location of the tagged asset.
- C. Passive tags do not communicate directly with the WLAN infrastructure, but instead they rely on the tag reader to communicate tag information to the
- D. With passive tags, AP transmit gain should be increased to supply extra power for near-field coupling or backscatter modulation from the tag to the AP since the passive tag lacks an internal power source.
