H3CSE-WLAN Sample Questions:
Question 1
Which of the following statements about signals is true
A. In theory, white noise affects all frequencies of a radio signal uniformly, while narrowband interference is noise only within a small range of frequencies.
B. The signal of each frequency point in the spectrum analyzer should be a standard sine wave if viewed through an oscilloscope.
C. There are two common methods for signal analysis: time domain analysis and frequency domain analysis. Time domain analysis is usually viewed with an oscilloscope, while frequency domain analysis is usually viewed with a spectrum analyzer.
D. The interference from FM radio is narrowband.
Question 2
It is true that the sequence of PSK certification, 802.1X certification and antenna 802.11 step-by-step competition is correct.
A. PSK authentication occurs during the authentication process, and the association process starts after the authentication is completed
B. PSK authentication occurs after the association is completed, and the authentication and encryption information exchange with the AP is completed through eapol
C. 802.1X authentication occurs during the authentication process, and the association process starts after the authentication is completed. The question bank is required for the association process.
D. 802.1X authentication occurs after the association is completed, and the authentication and encryption trust interaction with the AP is completed through eapol
Question 3
Which of the radio link handover control parameters is correct?
A. Link Switch Margin: The signal threshold for switching the backup link to the primary link. When the signal difference between the RSS I of the backup link and the RSS I of the primary link is greater than the Link Switch Margin value, the backup link switches to main link
B. Link Hold RSSI : The minimum signal strength required to establish and maintain a link
C. Link Saturation RSSI: When the signal strength of the opposite end exceeds this threshold, it may cause signal reception saturation, resulting in failure of demodulation and link failure. At this time, link switching will be performed immediately
D. Link Hold Time: In order to prevent frequent switching of the primary link, when the backup link switches to the primary link, the shortest duration of the primary link is maintained.
E. Link-maximum-number : The number of MESH links established between the on-board MR and the trackside, including the main link and the backup link
Question 4
The wireless controller models with a maximum number of managed APs of 6144 are
A. WX5560H
B. LSQM1WCMX40
C. LSQM1WCMX20
D. WX5540H
Question 5
The convenience of FIT AP network deployment and implementation is that the AP can be plug-and-play. Before installing the AP, which of the following operations are recommended
A. Record the correspondence between APs and connected switches and ports
B. Record the AP installation point, serial number, MAC address correspondence
C. Register the APs on site to ensure that all APs can be successfully registered on the AC
D. Perform license-related operations to ensure that the AC's license specifications can meet the requirements
