Question 2

In this question, you will compare the mobility processes of a network that supports WPA2-Personal and WPA2-Enterprise. Assume the use of a 15-character ASCII passphrase for WPA2-Personal and EAP-TTLS/MSCHAPv2 with WPA2-Enterprise. Also, assume that proprietary roaming protocols are not supported.

When a device transitions from one BSS to another within the same ESS, what steps must be performed in the WPA2-Enterprise transition that are not performed in the WPA2-Personal transition? (Choose two.)

Question 3

What statement is true of a WLAN design that supports Real-Time Location Services (RTLS) with 802.11 RFID asset tags? (Choose two.)

Select all that apply, then click Submit answer.

  • ○

    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.
  • ○

    Active RFID tags periodically transmit 802.11 beacon management frames that must be synchronized with the AP for proper location of the tagged asset.
  • ○

    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.

  • ○

    Passive tags do not communicate directly with the WLAN infrastructure, but instead they rely on the tag interrogator to communicate tag information to the infrastructure’s location tracking server/ database.
  • ○

    Active tags transmit directly to the APs and may not require 802.11 authentication and association to pass data traffic to the RTLS engine.
  • ○

    When tracking assets with passive RFID tags, some APs should be moved, or additional APs be added, to provide more accurate triangulation and location services.
