GB0-341-ENU Exam Training Practice Tests (H3CSE-WLAN)]

Question 1

In the g802.11b/g protocol, a total of 3 13 channels (1-13) are opened. Please select 3 channels that do not interfere with each other from these 13 channels. Which of the following groups is correct? (Multiple choice)

A. 1, 2, 3 B. 1, 5, 9 C. 1, 6, 11 D. 2, 7, 12

Correct Answer: C,D

Question 2

The following statement about signals, which is correct? (Multiple choice)

A. There are two common methods for signal analysis: time domain analysis and frequency domain analysis. Time domain analysis usually uses an oscilloscope to view the signal, while frequency domain analysis usually uses a spectrum analyzer. B. In theory, noise will uniformly affect all frequencies of radio signals, while narrow-band interference is noise that is only in a small range of frequencies. C. The interference produced by FM radio is narrow-band interference. D. The signal of each frequency point in the spectrum analyzer should be a standard sine wave if viewed through an oscilloscope.

Correct Answer: A,B,C,D

Question 3

When F FP IT AP cannot be registered online, what are the possible reasons? (Multiple choice)

A. AP and AC routes are unreachable | The license on the AC is not enough B. AP is not powered on C. The DHCP address pool is full and the AP cannot get an IP address D. The AP template serial number on the AC is incorrectly configured E. The radio port configuration on the AC is incorrect

Correct Answer: A,B,C,D

A. No B. Yes

Correct Answer: A

Question 8

The wireless client can search for WLAN signals but cannot associate with the AP. What are the possible reasons? (Multiple choice)

A. The encryption method of the client's wireless network card is inconsistent with the AP B. Too many users associated with the AP C. The AP is too far away or there are too many obstacles, and the signal strength is lower than the receiving sensitivity of the wireless network card D. There are strong interference sources in the surrounding environment

Correct Answer: A,B,C,D

Question 9
