- C . Maximal Ratio Combining
- D . Mandatory data rates
What type of standards-based encryption is used by office extension APs for the traffic tunnel? (Choose all that apply.)
- A . CAPWAP

- E . DTLS
Given: You are evaluating the theoretical and real-world RF gain benefits of transmit and receive features introduced by 802.11 with MIMO. This exercise allows you to quantify the features value in a real-world environment.
What is the maximum theoretical signal gain of chip-based TxBF and MRC (as features) when compared to the same AP using only a single antenna for transmit and receive (effectively simulating a 1×1 chip)?
- A . 2 Rx or Tx chains = 3 dBi gain 3 Rx or Tx chains = approx 5 dBi gain 4 Rx or Tx chains = 6 dBi gain
- B . 2 Rx or Tx chains = 1 dBi gain 3 Rx or Tx chains = 2 dBi gain 4 Rx or Tx chains = 3 dBi gain
- C . 2 Rx or Tx chains = 3 dBi gain 3 Rx or Tx chains = 6 dBi gain 4 Rx or Tx chains = 9 dBi gain
- D . 2 Rx or Tx chains = approx 4-6.5 dBi gain 3 Rx or Tx chains = approx 7-10 dBi gain
What basic RF math formula should be used as a baseline to convert an RF value in units of dBm into a value of mW? Note: “dBm” in the formulas represents the known dBm value
- A . 0 dBm = 3 mW
- B . 0 dBm = 1 mW
- C . 0 dBm = 2 mW
- D . 0 dBm = 4 mW
When you see the SKINNY protocol in a post-install validation protocol capture, what does this indicate?
- A . VoIP is used on the network
- B . Multicasting is used on the network
- C . HTTPS is in use
- D . Secure FTP is in use
The thermal noise is at 174 dBm/Hz. A spectrum analyzer has a resolution bandwidth of 1 kHz and a 5 dB noise figure.
What is the level of the noise floor?
- A . 174 dBm
- B . 139 dBm
- C . 144 dBm
- D . 204 dBm
During a post-deployment verification, you are requested to troubleshoot an area where users are experiencing poor throughput. They are using data communication only, mainly from laptops. You captured the frame showing an incorrect FCS. This frame is typical of those that were captured by the analyzer.
What does this frame reveal about the RF network in this area?
- A . One station seems to be streaming video, thus may have reserved significant bandwidth via admission control
- B . Contention Free is in place in this network, which may starve some non-QoS stations from access
- C . Multipath or excessive collisions seem to be an issue in this area
- D . The AP seems to be too far to provide enough coverage to this area
An MSA commonly addresses at least which two legal categories?
- A . Nondisclosure agreement
- B . Hold harmless
- C . Intellectual property protection
- D . Indemnity clause
What is the best method of gathering attenuation measurements from any building materials or objects?
- A . After measuring the RSSI in free space 5 meters (16.5 feet) apart, put an AP 4 meters (13 feet) away from the wall or object on one side
and your measuring device 0.67 meters (2 feet) away from the wall or object on the other side. Take measurement and compare the difference. - B . Use the pre-built attenuation values in the predictive design tool.
- 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 or object 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 provider’s websites.
You deployed an AP and installed its antenna, and you now need to set the AP transmit power. Given a desired EIRP of 21 dBm, and an antennagain of 5.85 dBd connected through 25 feet of cable with a loss specification of 4 dB/100 feet.
Assuming that there is no significant loss from the connectors, what should be the transmit power level for this AP?
- A . 10 mW
- B . 14 mW
- C . 20 mW
- D . 25 mW
