A. The distance settings between neighboring Mesh nodes must be the same. B. The 2.4 GHz frequency is recommended for Mesh. C. Short GI is recommended regardless of the distance to improve bandwidth on air interfaces. D. The power settings on neighboring Mesh nodes must be the same to ensure equivalent bidirectional bandwidth.

Correct Answer: A,D

Question 2

According to probe results reported by an AP, an AC can obtain neighbor relationships between the AP and surrounding devices (including authorized APs, rogue APs, and non-Wi-Fi devices), as shown in the following figure. To avoid reported data getting oversized, only data from authorized APs whose signal strength is greater than -85 dBm and rogue APs whose signal strength is greater than () dBm is reported.

A. -80 B. -85 C. -75 D. -90

Correct Answer: A

Question 3

Smart roaming indicates that STAs actively roam from one AP to another. The roaming is initiated by STAs.

A. FALSE B. TRUE

Correct Answer: A

Question 4

After CAC based on channel usage is configured to control user access on an AP, if the current channel usage exceeds the configured threshold, the AP will reject access requests of new STAs and force STAs to log out until the channel usage is lower than the threshold.

A. FALSE B. TRUE

Correct Answer: A

Question 5

A large enterprise uses direct forwarding for some SSIDs when deploying the WLAN.
Which of the following are the characteristics of direct forwarding? (Multiple Choice)

A. Service data do not need to be forwarded to the AC. There is no forwarding bottleneck. B. Wireless traffic can be centrally controlled. This forwarding mode has obvious advantages in user policy control and wireless roaming. C. Data packets are forwarded in a more secure way. D. It is easy for AC capacity expansion. You only need to increase the number of independent ACs.

Correct Answer: A,D

Question 6

Which of the following servers is the directory server?

Correct Answer: A

Question 7

Improper processing of which of the following packets will lead to packet congestion? (Multiple Choice)

A. Anycast B. Multicast packets C. Broadcast packets D. Unknown unicast packets

Correct Answer: B,C

Question 8

When dual-link HSB is configured, an AP sets up CAPWAP links with both the active and standby ACs.

A. FALSE B. TRUE

Correct Answer: B

Question 9

Which statement about the MAP on a Mesh network is FALSE?

A. MAP is a special form of MP. B. Any MP supporting the AP function can provide access to STAs. C. An MAP is usually connected to STAs. D. MAP is a special form of MPP.

Correct Answer: D

Question 10

The Agile Controller supports multiple authentication methods in wireless access authentication.
Which of the following statements is FALSE?

A. The Agile Controller does not support MAC address bypass authentication. B. Multiple authentication methods can be used to authenticate users. C. The Agile Controller supports Portal authentication. D. The Agile Controller supports 802.1x authentication.

Correct Answer: A

Question 11

In a scenario that uses the Agile Controller to implement admission control, which of the following statements is TRUE about the roles of the RADIUS server/client?

A. The authentication device (for example, 802.1x-enabled switch) functions as the RADIUS server, while the user terminal functions as the RADIUS client. B. The Agile Controller integrates all functions of the RADIUS server and client. C. The Agile Controller functions as the RADIUS server, while the authentication device functions as the RADIUS client. D. The Agile Controller functions as the RADIUS server, while the user terminal functions as the RADIUS client.

Correct Answer: C

Question 12

Which of the following statements are TRUE about communication between the active/standby ACs with servers in WLAN HSB mode? (Multiple Choice)

A. In load balancing mode, only one AC communicates with servers. B. In VRRP HSB scenarios, both the active and standby ACs advertise the virtual IP address or MAC address to servers. The two ACs communicate with servers using the virtual IP address. C. In VRRP HSB scenarios, the active and standby ACs can advertise the virtual IP address or MAC address to servers. Only one AC communicates with servers using the virtual IP address. D. In load balancing mode, both the active and standby ACs communicate with servers.

Correct Answer: C,D

Question 13

On a WLAN that uses the Agile Controller as the admission control server, which of the following is NOT the cause of 802.1x authentication failures?

A. The accounting interval is not configured. B. The key used by the Agile Controller to connect to the device is different from the key configured on the device. C. Port 1813 is used on the server. D. The matched authorization rule defines the action "deny".

Correct Answer: A

Question 14

Which of the following statements are TRUE about radio resource management? (Multiple Choice)

A. Radio resource management can improve user access security. B. Radio resource management enables a WLAN to adapt to changes in the radio environment by dynamically adjusting radio resources. C. Radio resource management can improve Internet experience of users. D. Radio waves will attenuate when they are transmitted over air, degrading service quality for wireless users. Therefore, radio resource management is needed.

Correct Answer: B,C,D

Question 15

In which authentication mode can user information synchronized by the Agile Controller be used? (Multiple Choice)

A. 802.1x authentication B. Portal authentication C. Agile Controller login authentication D. MAC address bypass authentication
