A. True

B. False

Correct Answer: B

Question 2

An enterprise uses WAC+FITAP networking, and users find that the AP fails to go online. The cause of this failure may be that the AP and WAC software versions do not match.

A. True

B. False

Correct Answer: A

Question 3

When an engineer was debugging a wireless network at a customer site, the radio frequency tuning function configured on the device did not take effect. The engineer checked the current radio frequency tuning status on the wireless controller, and the following was displayed. After analyzing the displayed information, which of the following may be the cause of the failure of radio frequency calibration?

A. AP did not detect neighbor information

B. Device tuning is not completed

C. The channel and power automatic selection functions are disabled on the device.

D. No VAP template is configured on the device

Correct Answer: C

Question 4

When an enterprise deployed a WLAN network, in order to meet the enterprise's security requirements, Portal authentication was used to authenticate wireless users. Now users report that when they enter any IP address in the browser, they can be redirected to the Portal page and access it normally, but when they enter any domain name, they cannot be redirected to the Portal page. So, what are the possible reasons for the above situation? (Multiple choice)

A. The terminal is disconnected from the DNS server network

B. The terminal did not obtain an IP address

C. There is no DNS server in the network

D. WAC and AP do not allow the DNS server IP address to be released through free-rule

Correct Answer: A,C,D

Question 5

In WLAN networking, which of the following descriptions about GI are correct? (Multiple choice)

A. The smaller the GI, the higher the transmission efficiency

B. GI refers to the protection interval between symbols, which is used to reduce the impact of interference.

C. GI can be divided into normal GI and Short GI. When there are few interference factors in the indoor environment, it is recommended to use Short GI.

D. The larger the GI, the stronger the anti-interference ability

Correct Answer: A,B,C,D

Question 6

When HSB is synchronizing data, in order to further ensure that the table entries on the primary and backup devices are completely consistent, the backup device will check whether its existing session table entries are consistent with the primary device every 20 minutes. If they are inconsistent, the session table entries on the primary device will be synchronized to the backup device.

A. True

B. False

Correct Answer: B

Question 7

What is the function of AC in wireless network? (Multiple choice)

A. Wireless Intrusion Detection

B. Centralized management of APs

C. Send a beacon frame

D. Implement roaming function

Correct Answer: A,B,D

Question 8

Which of the following factors should be considered when deploying the AP9330DN indoor distribution solution? (Multiple choice)

A. Try to hide the antenna in the ceiling

B. The antenna is facing the coverage area

C. It is recommended to use a dual-stream dual-frequency directional antenna

D. Try to choose a shorter feeder

Correct Answer: B,C,D

Question 9

During the MAC authentication process, to prevent illegal users from brute-forcing the user name and password of the terminal, the silent function of MAC authentication can be enabled. By default, if a user fails to authenticate five times within 600 seconds, the access device will discard the user's authentication request within the next 60 seconds.

A. True

B. False

Correct Answer: B

Question 10

Drag and Drop Question
In WLAN network planning, collecting information about the signal strength and signal interference on site is a very important step. The premise is that we need to understand the basic concepts of related parameters. Please correspond the following meanings and basic concepts to.

(Multiple choice)

A. Support viewing the simulation effect of AP in local area

B. Support multiple simulation heat map types

C. Supports viewing the proportion of each signal strength interval under the current simulation

D. Supports deployment of mobile phones, laptops or tablets to simulate terminal access

Correct Answer: A,B,C,D

Question 12

When planning a WLAN network, it is recommended that the signal strength within the wireless network coverage area is greater than the edge field strength in the network planning indicators.

A. True

B. False

Correct Answer: A

Question 13

Drag and Drop Question
In indoor non-high-density deployment scenarios (AP spacing of 10 to 15 meters), 5G networks can automatically identify service priorities, service throughput, and interference through a dynamic bandwidth selection algorithm, and prioritize allocating more network resources to high- load areas to improve user experience.
Please sort the following steps of the dynamic bandwidth selection algorithm according to the workflow.

Correct Answer:

Question 14

In WLAN networks, the spatial direction of the electric field vector in the direction of maximum radiation of the antenna is usually taken as the polarization direction of the electromagnetic wave.
Which of the following descriptions of antenna polarization are correct? (Multiple choice)

A. Antennas can be divided into single-polarized antennas and dual-polarized antennas according to polarization.

B. Single polarization and dual polarization are both linear polarizations in nature, usually in two types:
horizontal polarization and vertical polarization.

C. Dual-polarized antennas use the same antenna for both reception and transmission, and one antenna contains both vertical and horizontal polarization modes

D. Single-polarized antennas receive and transmit signals in two separate antennas, and one antenna contains only one polarization mode, vertical or horizontal.

Correct Answer: A,B,C,D
