When designing for OFDMA, why might the same channel bandwidth result in greater efficiency than that available in 802.11n and 802.11ac?
- A . The design will use MU-MIMO, which is 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 802.11ac.
- 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.
When performing an indoor predictive site survey to make the WLAN planning and design cycle more efficient, what is a best practice for configuration of the simulated APs in the predictive modeling software?
- A . All simulated APs should be set to 20 MHz channels only.
- B . Always use the default 2.2 dBi omnidirectional antenna patterns for simulated APs.
- C . If dynamic RRM will be used, AP transmit power should be set to an estimated average level of the expected client devices, such as 25 mW.
- D . Defining custom AP and antenna patterns will yield more accurate prediction data than the pre-configured vendor AP/antenna combinations.
You performed a site survey with two USB Wi-Fi adapters using a special driver written for the site survey software. After deployment, you realized that the client devices used by your customer are getting lower RSSI values than that shown during your site survey.
What is the most likely reason for this result?
- A . USB Wi-Fi adapters designed for site surveys may have better sensitivity than regular Wi-Fi cards installed in client devices.
- B . The transmit power on the APs is higher than needed.
- C . Regular Wi-Fi cards installed in client devices do not support the same protocols as survey adapters.
- D . USB Wi-Fi adapters have a greater sensitivity than internal Wi-Fi adapters.
How much more power can a 1 Mbps 802.11b signal have than a 54 Mbps 802.11g signal if it is sent
through a saturated amplifier?
- A . 5 dBm
- B . 2 dBm
- C . 2 dB
- D . 5 dB
You have determined the best mounting locations for APs in a given installation. The facilities manager has asked you to change the locations for several APs due to aesthetic concerns. You suggest mounting the APs in the ideal locations and painting them so they go unnoticed in the environment.
What is a valid recommendation or consideration when painting APs?
- A . Always use paints with metallic dye in them to prevent potential RF propagation impact.
- B . Painting APs will significantly reduce the output power.
- C . Painting APs may void the product manufacturer’s warranty.
- D . Most AP models for indoor environments come in a variety of form factors and colors. Painting is never recommended.

An amplifier has a 1 dB compression point of 32 dBm and a gain of 20 dB.
Which is the highest average input power shown here that would be safe to operate a 24 Mbps 802.11g signal so that spectral regrowth is not a problem?
- A . 5 dBm
- B . 0 dBm
- C . −5 dBm
- D . 10 dBm
Your customer requires a security solution where client credentials are used, not a Protected Access Credential (PAC), and the authentication server must have a certificate with optional client certificate use.
Which EAP (Extensible Authentication Protocol) method is the best fit for these requirements?
- A . EAP-FAST
- B . EAP-TTLS
- C . EAP-TLS
- D . LEAP
To increase capacity in a coverage-based wireless network, which of the following techniques are typically recommended? (Choose all that apply.)
- A . Maximize airtime usage by disabling lower data rates.
- B . Add additional APs and use directional antennas.
- C . Turn up power on the access points.
- D . Lower power on the access points and, after careful planning, add more AP
You are validating client association capabilities to an 802.1X/EAP secure SSID. The RADIUS server’s IP address is 10.100.50.25, and the default RADIUS authentication port is being used. None of the clients can associate with the SSID. After verifying that both the server and the RADIUS service are operational, you find that the authenticator (such as the AP or controller) is not communicating properly with the RADIUS server.
What is your next troubleshooting step?
- A . Verify that the shared secret between the authenticator and the RADIUS server is the correct
- B . Reboot the clients to empty the shared secret cache
- C . Reboot the server to empty the shared secret cache
- D . Restart the RADIUS service to empty the shared secret cache
