Question 1

What is the formula used to calculate the Duration field value in an RTS frame?

  • A. RTS Duration field = CTS duration
  • B. RTS Duration field = Data or management to be sent frame duration
  • C. RTS Duration field = Data or management frame to be sent duration + CTS duration + one ACK duration + three SIFS
  • D. RTS Duration field = Data or management frame to be sent duration + CTS duration
Answer:

C

Question 2

Why would a STA that supports 802.11k Radio Measurement send a Neighbor Request to an AP?

  • A. To learn about neighboring interference sources and tune its RF radio accordingly
  • B. To inform the current AP about the STAs intent to roam to a neighboring AP, ensuring a seamless handover
  • C. To request a list of neighboring APs which the STA can use as roaming candidates
  • D. To request a list of neighboring STAs which enables the STA to better pick the right protection mechanisms
Answer:

C

Question 3

When would you expect to see a Reassociation Request frame?

  • A. Every time a STA associates to an AP to which it has previously been associated
  • B. Only when a STA is using FT roaming
  • C. Only when a STA roams back to an AP it has previously been associated with
  • D. Every time a STA roams
Answer:

D

Question 7

Where, in a protocol analyzer, would you find an indication that a frame was transmitted as part of
an AMPDU?

  • A. The HT Operation Element
  • B. A-MPDU flag in the HT Control Field
  • C. A-MPDU flag in the Frame Control Field
  • D. The Aggregation flag in the Radio Tap Header
Answer:

B

Question 8

When performing protocol analysis, you notice a high number of RTS/CTS frames being transmitted
on an HT network. You suspect this may be due to HT protection mechanisms. Where in the Beacon
frame would you look to determine which one of the four HT protection modes the AP is operating
in?

  • A. HT Protection Element
  • B. HT Information Element
  • C. HT Operation Element
  • D. Non-HT Present Element
Answer:

A

Question 9

What does the value of the Listen Interval field in an Association request frame indicate?

  • A. How long a STA performing active scanning will listen for Probe Responses before changing channels
  • B. How often a STA will go off channel to look for other BSSs
  • C. How often a STA in power save mode wakes up to listen to Beacon frames
  • D. How long a STA waits for an Ack before retransmitting the frame
Answer:

C

Explanation:
