Question 5

In Agile Controller functions description, 5W1H is often mentioned. Here, 5W refers to who (connects to the network), where (is the users), when (does the user connect to the network), why (does the user connect to the network), and what (device does the user use to connect to the network).

A. TRUE

B. FALSE

Correct Answer: B

Question 6

CAC is implemented in three modes. Which of the following statements about CAC implementation based on channel usage is FALSE?

A. An AP periodically detects the channel usage of a radio. Once the channel usage falls below the threshold, the AP sends a clear alarm, allowing new users to go online.

B. If the channel usage reaches the threshold after a new user goes online, an AP will reject access requests of new users, send alarms, but cannot hide its SSID.

C. When a roaming user attempts to access an AP, the AP checks whether the channel usage reaches the CAC roaming threshold. If so, the AP will reject the access request of the roaming user and send alarms.

D. When receiving a new access request, an AP calculates the current channel usage and checks whether the channel usage reaches the threshold. If not, the AP allows the user to go online.

Correct Answer: B

Question 7

shared-key ciper huawei
url-template huawei

A. Number of the port that the AC6005 uses to receive Portal protocol packets

B. Number of the port that the AC6005 uses to process Portal protocol packets

C. Destination port number in the packets that the AC6005 sends to the Portal server

D. Source port number in the packets that the AC6005 sends to the Portal server

Correct Answer: C

Question 8

A. 3.6m

B. 9.7m

C. 5.6m

D. 8m

Correct Answer: D

Question 9

Which of the following statements about active neighbor probe is FALSE?

A. Active probe is used to obtain the maximum interference signal strength between authorized neighboring APs, in which signal strength of the neighboring AP is the key.

B. Active probe is used to establish neighbor relationships between authorized APs.

C. Active probe and passive probe are used to collect interference information from rogue APs.

D. An AP periodically sends Probe Request frames destined for a specified multicast address on different channels. After receiving the frames, surrounding APs learn that the AP is a neighbor.
