Demo Questions

Question 1
What statement is true concerning the use of Orthogonal Frequency Division Multiplexing (OFDM) modulation method in IEEE 802.11 WLANs?
  1. OFDM was used by Frequency Hopping Spread Spectrum (FHSS) PHY devices.
  2. OFDM was first introduced in 802.11 and is used by the ERP, HT and VHT PHYs as well.
  3. OFDM implement BPSK modulation to allow for data rates up to 7 Gbps.
  4. OFDM modulation is used only in 5 GHz 802.11 transmissions.
Correct answer: D
Question 2
Which IEEE 802.11 physical layer (PHY) specification includes support for and compatibility with both ERP and HR/DSSS?
  1. VHT (802.11ac)
  2. OFDM (802.11a)
  3. DSSS (802.11-Prime)
  4. HT (802.11n)
Correct answer: D
Question 3
An 802.11-based network uses an AP and has several connecting clients. The clients include iPhones, iPads, laptops and one desktop. What WLAN use case is represented?
  1. WPAN
  2. Ad-hoc
  3. BSS
  4. IBSS
Correct answer: C
Question 4
What factor is likely to cause the least impact on the application layer throughput of an 802.11n client station in a 2.4 GHz HT BSS?
  1. Increasing or decreasing the number of spatial streams in use by the client station and AP
  2. Implementation of several other clients in the same BSS using 802.11 g radios
  3. Implementing Fast BSS Transition (FT) for roaming
  4. RF interference from more than 10 nearby Bluetooth transmitters
Correct answer: A
Question 5
What ID is typically mapped to an AP’s MAC address if a single BSS is implemented?
  1. VLAN ID
  2. BSSID
  3. Device ID
  4. SSID
Correct answer: B
Question 6
What is appended to the end of each 802.11 data frame after the payload?
  1. FCS
  2. Preamble
  3. MAC header
  4. PHY header
Correct answer: A
Question 7
When an ACK frame is not received by the transmitting STA, what is assumed?
  1. The frame was correctly delivered
  2. The frame was not delivered and must be retransmitted
  3. The receiver is offline
  4. The receiver processed the frame, but did not respond with an ACK frame because 802.11w is enabled
Correct answer: B
Question 8
When a client station sends a broadcast probe request frame with a wildcard SSID, how do APs respond?
  1. For each probe request frame, only one AP may reply with a probe response.
  2. Each AP responds in turn after preparing a probe response and winning contention.
  3. Each AP checks with the DHCP server to see if it can respond and then acts accordingly.
  4. After waiting a SIFS, all APs reply at the same time with a probe response.
Correct answer: B
Question 9
What security solution is deprecated in the 802.11 standard and should never be used in any modern WLAN deployment?
  1. AES
  2. Shared Key Authentication
  3. CCMP
  4. Open System Authentication
Correct answer: B
Question 10
You are reconfiguring an AP to use the short guard interval. How long will the new guard interval duration be after the change?
  1. 400 ns
  2. 10 ms
  3. 800 ns
  4. 104 ms
Correct answer: A
