• Question 56:

  Given a protocol analyzer can decrypt WPA2-PSK data packets providing the PSK and SSID are

  configured in the analyzer software.

  When performing packet capture (in a non-FT environment) which frames are required in order for PSK

  frame decryption to be possible?

  A. Authentication

  B. Reassociation

  C. 4-Way Handshake

  D. Probe Response

  Correct Answer: C

• Question 57:

  An RST frame should be acknowledged by which frame?

  A. Ack

• Question 58:

  You have installed a new 802.11ac WLAN configured with 80 MHz channels. Users in one area are complaining about poor performance. This area is currently served by a single AP. You take a spectrum analysis capture in the poor performing area. While examining the waterfall plot you notice the airtime utilization is higher on the first 20 MHz of the 80 MHz channel when compared to the rest of the channel. What do you conclude?

  A. The AP is misconfigured and needs to be reconfigured to 80MHz operation

  B. RRM is enabled and has dynamically picked a 20 MHz channel

  C. The first 20 MHz is the AP's primary channel and higher airtime utilization on the primary channel is normal when an AP Is configured for 80 MHz operation

  D. Non Wi-Fi interference is preventing the APs 80 MHz operation

  Correct Answer: C

• Question 59:

  When a data frame is encrypted with WPA2, to which portion of the frame is the encryption applied?

  A. Frame body excluding the LLC

  B. Frame body including the LLC

  C. Frame body and MAC Header

  D. The whole MPDU

  Correct Answer: C

• Question 60:

  In the 2.4 GHz band, what data rate are Probe Requests usually sent at from an unassociated STA?

  A. The minimum basic rate

  B. 1 Mbps

  C. 6 Mbps

  D. MCS 0

  Correct Answer: B
