Which of the following statements are true about Huawei ' s smart roaming solution?

A.

In high-density coverage scenarios, STAs generally have good signals. Smart roaming can enable STAs to associate with APs that have better signals, significantly improving channel performance.

B.

The smart roaming solution resolves the sticky STA problem and enables STAs to proactively roam to the optimal AP.

C.

Smart roaming enables each STA to associate with the nearest AP.

D.

In common coverage scenarios, STAs with poor signal strength are steered to APs with better signal strength, improving service experience for users and overall channel performance.

Which of the following statements is false about STA roaming tracks on a Huawei WAC?

A.

If the values of In Rx/Tx, In RSSI, Out Rx/Tx, and Out RSSI are low, the signal coverage in this area may be abnormal.

B.

If the values of In Rx/Tx, In RSSI, Out Rx/Tx, and Out RSSI are good, the signal coverage in this area is excessively dense.

C.

It is unreasonable that the value of Out RSSI is lower than the signal strength of the next associated AP.

D.

It is reasonable that the value of Out Rx/Tx is lower than the signal strength of the next associated AR

An AP may preferentially use the BTM mode to steer some STAs. With which of the following protocols are such STAs compliant?

A.

802.11k

B.

802.11i

C.

802.11r

D.

802.11v

Which of the following configurations may cause ST As to experience a slow Internet connection? (Select All that Apply)

A.

QoS CAR is configured in the traffic profile.

B.

Radio 1 of APs is disabled.

C.

TKIP encryption is configured, causing a low link setup rate.

D.

Rate limiting is configured in the SSID profile.

After RADIUS packet retransmission is triggered, if the device detects that the RADIUS server status is Down, the device marks the RADIUS server status as Down. If the maximum number of retransmissions has not been reached, which of the following will occur?

A.

The device retransmits the authentication request packet only once to the RADIUS server.

B.

The device retransmits the packet at most three more times, and stops retransmission once it receives a response packet or the maximum number of retransmissions is reached.

C.

The device continues to retransmit packets until it receives a response packet or the maximum number of retransmissions is reached.

D.

The device stops retransmission immediately.

Which of the following statements about the home agent are true? (Select All that Apply)

A.

The home agent communicates with the gateway on the STAs1 home network at Layer 2.

B.

The home agent communicates with the gateway on the STAs ' home network at Layer 3.

C.

A home AP can function as a home agent of STAs.

D.

A home WAC can function as a home agent of STAs.

Which of the following statements about EAP relay and EAP termination are false? (Select All that apply)

A.

In EAP termination mode, an access device encapsulates EAP packets sent by an 802. IX client Into RADIUS packets, without processing the data in the EAP packets.

B.

In EAP relay mode, an access device extracts information from EAP packets, encapsulates the information into RADIUS packets, and sends the RADIUS packets to an authentication server.

C.

In EAP termination mode, an access device extracts client authentication information from the EAP packets sent by a client and encapsulates the information using the standard RADIUS protocol. The access device supports only the EAP MD5-Challenge authentication method.

D.

The EAP termination mode simplifies the processing on an access device and supports various authentication methods. However, this mode requires an authentication server to support EAP and have high processing capability.

Which of the following items is not involved in the HLD phase?

A.

Capacity planning

B.

Network design

C.

AP position planning

D.

Deployment planning

Which of the following statements are true about data collection of IMaster NCE-Campuslnslght? (Select All that Apply)

A.

iMaster NCE-Campuslnsight uses telemetry to Implement efficient data collection.

B.

Calculated data can be displayed on iMaster NCE-Campuslnsight only after a license Is loaded on the device management page.

C.

To collect data from WLAN devices, ensure that WACs can communicate with the southbound IP address of iMaster NCE-Campuslnsight. APs do not need to communicate with the southbound IP address of iMaster NCE-Campuslnsight.

D.

The UTC time of iMaster NCE-Campuslnsight must be the same as that of its managed devices.

Huawta WACs support the setting of the RTS/CTS threshold. If the packet length exceeds the threshold, the AP sends RTS frames to clear the channel before sending data frames. If the packet length is less than the threshold, the AP does not use this mechanism. This prevents conflicts caused by hidden STAs.

A.

TRUE

B.

FALSE
