QUESTION 106
IEEE 802.11r-2008 or fast BSS transition (FT), also called "fast roaming," Which 802.11 standard performs the PTK calculations in advance to enable fast client roaming?

A.        802.1 11r
B.        802.1 11i
C.        802.1 11k
D.        802 1 11w

Answer: A
Explanation:
802.11r, Which is the IEEE standard for fast roaming, introduces a new concept of roaming where the initial handshake with the new AP is done even before the client roams to the target AP, which is called Fast Transition (FT). The initial handshake allows the client and APs to do the Pairwise Transient Key (PTK) calculation in advance. These PTK keys are applied to the client and AP after the client does the reassociation request or response exchange with new target AP.

QUESTION 114
You are planning the coverage for wireless VoIP by using Ekahau. Which signal strength does Ekahau recommend using for VoIP?

A.        -84 dBm
B.        -76 dBm
C.        -67 dBm
D.        -53 dBm

Answer: C
Explanation:
Each vendor has their own recommended signal strength for a given data rate or application. For instance, one vendor may recommend designing their VoIP solution at -67 dBm (perhaps the most widely-used value for VoIP deployment if I had to choose one), while another may say -70 dBm. In most cases the values will differ only by a couple dB.
