  • B. NEMA enclosures
  • C. Ethernet cables
  • D. PoE


Answer : B

Which document provided to your customer should include all devices and parts that will be used during the deployment of their WLAN infrastructure?

  • A. SoW
  • B. BoM
  • C. Design report
  • D. Project plan


Answer : B

What limitation exists when WMM is not enabled on an 802.11 WLAN?

  • A. 802.11 QoS will not be available
  • B. The maximum channel-width will be 20MHz
  • C. EDCA values will change
  • D. Only two ACs will be available


Answer : A

When designing for OFDMA, why might the same channel bandwidth result in greater efficiency than that available in 802.11n and 802.11 ac?

  • A. The design will use MU-MIMO, which if not available in either 802.11n or 802.11ac
  • B. The design will use transmit beamforming, which is not available in either 802.11n or 802.11 ac
  • C. The design will use RUs that allow for transmissions to multiple client devices concurrently without the use of MU-MIMO
  • D. The clients will use UL MU-MIMO coupled with DSSS, which was not available in 802.11n or 802.11ac.


Answer : C

What service must be implemented on your customer’s network to authenticate users against an LDAP database before granting access to the WLAN infrastructure?

  • A. SSH
  • B. RADIUS
  • C. SFTP
  • D. TLS


Answer : B

What is the best method of gathering attenuation measurements from wall materials?

  • A. After measuring the RSSI in free space meters (16.5 feet) apart, put an AP 4 meters (13 feet) away from the wall on one side and your measuring device 1 meter (3.2 feet) away from the wall minus the width of the wall. Take measurements and compare the difference.
  • B. Use the pre-built attenuation values in the predictive design tool as they are more accurate than free-space metrics gathered with commercial devices.
  • C. After measuring the RSSI in free space 1 meter (3 feet) apart, put an AP 0.32 meters (1 feet) away from the wall on one side and your measuring device 0.67 meters (2 feet) away from the wall on the other side. Take measurements and compare the difference.
  • D. Look on the Internet for attenuation values for each one of the materials that might attenuate the Wi-Fi signal using the material providers’ websites.


Answer : C

Which type of authentication and encryption method is mandatory for Voice Enterprise certified devices as specified by the Wi-Fi Alliance?

  • A. WPA2/AES Personal
  • B. WPA2/TKIP Enterprise
  • C. WPA2/AES Enterprise
  • D. WPA/TKIP Personal

  • C. Bill of Materials
  • D. Physical installation guide


Answer : D

In addition to a copy of your design, which tools should you provide to ensure the installation team correctly deploys access points (APs) in the specified locations within a multi-floor indoor design?

  • A. 150
  • B. 62
  • C. 43
  • D. 22


Answer : C

When deploying a new WLAN infrastructure using Power over Ethernet (PoE) to power the access points (APs), you find that a known good AP is not powering up. You connect your laptop using the same cable without any issues. What is the most likely reason the AP did not power up?

  • A. Missing AP licenses on the controller
  • B. Spanning-tree convergence
