Demo Questions

Question 1
What statement about the beamwidth of an RF antenna is true?
  1. Vertical beamwidth is displayed (in degrees) on the antenna’s Azimuth chart.
  2. Horizontal and vertical beamwidth are calculated at the points where the main lobe decreases power by 3 dB.
  3. The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.
  4. When antenna gain is lower, the beamwidth is also lower in both the horizontal and vertical dimensions
Correct answer: B
Question 2
You are the network administrator for ABC Company. Your manager has recently attended a wireless security seminar. The seminar speaker taught that a wireless network could be hidden from potential intruders if you disabled broadcasting of the SSID in Beacons and configured the access points to ignore Probe Request frames that have a null SSID field. Your manager suggests implementing these security practices. What response should you give to this suggestion?
  1. This security practice prevents manufacturers’ client utilities from detecting the SSID. As a result, the SSID cannot be obtained by attackers, except through social engineering, guessing, or use of a WIPS.
  2. Any 802.11 protocol analyzer can see the SSID in clear text in frames other than Beacons frames. This negates any security benefit of trying to hide the SSID in Beacons and Probe Response frames.
  3. To improve security by hiding the SSID, the AP and client stations must both be configured to remove the SSID from association request and response frames. Most WLAN products support this.
  4. Any tenants in the same building using advanced penetration testing tools will be able to obtain the SSID by exploiting WPA EAPOL-Key exchanges. This poses an additional risk of exposing the WPA key.
Correct answer: B
Question 3
What cipher suite is specified by the 802.11 standard and is not deprecated?
  1. Wired Equivalent Privacy
  2. Counter Mode with CBC-MAC Protocol
  3. Shared Key Authentication
  4. Temporal Key Integrity Protocol
Correct answer: B
Question 4
When implementing PoE, what role, if any, is played by a switch?
  1. PSE
  2. PD
  3. Power splitter
  4. Midspan injector
Correct answer: A
Question 5
You are managing a wireless access point in autonomous mode using the Web based interface. You capture traffic during this management task and notice that you can see the HTML code of the Web pages used for access point management. What error in administration could be the cause of this security concern?
  1. HTTP is in use instead of HTTPS
  2. The AP is not an 802.11ax AP
  3. The WPA3-SAE secret key is incorrect
  4. WPA2 is disabled on the WLAN
Correct answer: A
Question 6
Given that the center frequency of channel 1 in the 2.4 GHz band is 2.412 GHz (2412 MHz). What is the center frequency of channel 4?
  1. 2.422 GHz
  2. 2.417 GHz
  3. 2.413 GHz
  4. 2.427 GHz
Correct answer: D
Question 7
During a post-implementation survey, you have detected a non-802.11 wireless device transmitting in the area used by handheld 802.11g scanners. What is the most important factor in determining the impact of this non-802.11 device?
  1. Antenna gain used
  2. Airtime utilization
  3. Receive sensitivity
  4. Protocols utilize
Correct answer: B
Question 8
You are deploying a WLAN with the access points configured for 10 mW of output power on the 2.4 GHz radios and 20 mW of output power on the 5 GHz radios. Some semi-directional antennas are also in use. What kind of deployment is more likely described if this is a proper design decision?
  1. High Density
  2. Small Retail Store
  3. SOHO
  4. Residential
Correct answer: A
Question 9
You are troubleshooting a client issue on a Windows laptop. The laptop can see and connect to 2.4 GHz APs, but it does not see 5 GHz APs though it has a 5 GHz radio. While evaluating the issue, you determine that this problem is happening for all the laptops of this model in the organization. Several other tablets connect on channel 48 and channel 52 in the same work areas. Among the following choices, what is the likely problem?
  1. The access points are configured to disallow 5 GHz
  2. The client drivers are faulty and should be upgraded
  3. The clients are configured to use WPA and 5 GHz channels only support WPA2
  4. The antennas in the laptops have insufficient gain to detect the 5 GHz signals
Correct answer: B
Question 10
A WLAN is implemented using wireless controllers. The APs must locate the controllers when powered on and connected to the network. Which one of the following is a method commonly used to locate the controllers by the APs?
  1. SNMP
  2. NTP
  3. DHCP
  4. GRE
Correct answer: C
Question 11
You are troubleshooting a problem with interference from a non-802.11 device. Given that the device is not a WLAN device, you cannot use a protocol analyzer and have chosen to use a spectrum analyzer. You want to view the signal from the interfering device over time to see the activity that it is generating. What common spectrum analyzer view should you use for this analysis?
  1. Clients
  2. Waterfall/Spectrogram
  3. Real-Time FFT
  4. Aps
Correct answer: B
