Looking at a client radio specification sheet that states Receive Sensitivity of 82 dBm @ 18 Mbps would mean:
- A . It would need to hear a signal <82 dBm in order to use the 24 Mbps PHY rate.
- B . It is only capable of transmitting at 18 Mbps PHY rates at 82 dBm.
- C . It must hear a signal >82 dBm in order to demodulate the 18 Mbps PHY rate.
- D . It must hear a signal <82 dBm in order to demodulate the 18 Mbps PHY rate.
Who should be in the final meeting from the customer-side after successfully implementing a WLAN infrastructure?
- A . CEO or CFO
- B . End-users
- C . The customer’s customers
- D . Remote workers
You’re preparing to perform a site survey for a company that processes meat. Some areas are restricted due to high-security.
What do you have to do in order to proceed with the site survey?
- A . Gain appropriate access and clearance to perform the site survey.
- B . Gain meat processing access certification from the FDA.
- C . Ensure that you and your team are using food industry approved USB adapters for the survey.
- D . Just begin the survey, they will understand
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
A cable with 2.5 dB of loss is used to measure the return loss of an antenna. The measured value in-band is shown to be larger than 20 dB.
What is the actual return loss of the antenna, and is it considered to be a reasonable value?
- A . Larger than 15 dB and yes
- B . Larger than 15 dB and maybe
- C . Larger than 17.5 dB and yes
- D . Larger than 17.5 dB and no
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
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 are being asked to design a WLAN for a number of WLAN clients that will use Telnet as the primary application. The customer has asked that you use only the number of APs necessary because of the complex installation and construction costs each AP installation will incur in this particular environment.
What design factors do you consider?
- A . Omnidirectional antennas should be used to maximize cell overlap.
- B . Use 11 Mbps as the lowest basic rate.
- C . Clients could benefit from RTS/CTS mode for all transmissions.
- D . AP transmit power should be turned down to minimize co-channel interference.
During your first pre-deployment meeting with the deployment team, you hand out the full design documentation to all of them.
What’s your primary goal during this meeting?
- A . To explain design decisions and ensure understanding of design documents.
- B . To discuss AP functionality.
- C . To explain how Wi-Fi works.
- D . To justify the budget.
A business traveler from North America is in Europe. The hotel only provides coverage in 2.4 GHz. The traveler connects to the hotel’s SSID and notices an AP in the hotel room. However, the laptop reports a very low RSSI when connected. The traveler does not have the same problem when connecting in the lobby.
What would be the most likely cause of the low RSSI in the hotel room?
- A . The AP in the room is using ZigBee instead of Wi-Fi.
- B . The AP in the room is transmitting on channel 13 and the traveler associated to a non-channel 13 AP located elsewhere.
- C . The switchport that the AP is connected to is only capable of transmitting at 10 Mbps.
- D . The AP in the room is using Bluetooth instead of Wi-Fi.
