Which of the following Wi-Fi 6 AP models supports three radios?

  1. AirEngine 5762-12
  2. AirEngine 6761-21T
  3. AirEngine 5761-21
  4. AirEngine 5761-11

Answer(s): B

Explanation:

Understanding Wi-Fi 6 AP Radios:

Wi-Fi 6 APs typically have two or three radios. Three-radio APs provide additional capacity and performance, making them ideal for high-density environments.

Analysis of Each Model:

AirEngine 5762-12:This model supportstwo radios(2.4 GHz and 5 GHz).

AirEngine 6761-21T:This model supportsthree radios, including an additional IoT radio for Internet of Things (IoT) applications.

AirEngine 5761-21:This model supportstwo radios.

AirEngine 5761-11:This model supportstwo radios.

Conclusion:The correct answer is Option B, as the AirEngine 6761-21T supports three radios.

A higher antenna gain indicates stronger signals and more coverage. Therefore, an AP with a higher antenna gain which is within the specified range of country is preferred.

  1. TRUE
  2. FALSE

Answer(s): A

Explanation:

Understanding Antenna Gain:

Antenna gain refers to the ability of an antenna to focus or direct radio frequency (RF) energy in a specific direction. Higher gain antennas provide stronger signals and extended coverage in the direction they are focused.

Impact on AP Selection:

In scenarios where long-range coverage or better signal strength is required, an AP with a higher antenna gain (within regulatory limits) is preferred.

However, it is important to ensure that the antenna gain complies with the regulatory requirements of the country where it is deployed.

Conclusion:The statement is TRUE because higher antenna gain improves signal strength and coverage, making such APs desirable for specific use cases.

Which of the following statements are TRUE about Huawei's audio and video service experience assurance? (Select All that Apply)

  1. By default, scheduling is performed based on the priorities in descending order: VI -> VO -> BK -> BE.
  2. Beacon frames can be broadcast to instruct APs to suppress heavy-traffic users.
  3. According to Huawei lab test data, the delay of voice and video services in congestion scenarios is 56% lower than the industry average.
  4. By default, scheduling is performed based on the priorities in descending order: VI -> VO -> BE -> BK.
  5. Heavy-traffic services are automatically suppressed.

Answer(s): B,C,D

Explanation:

Overview of Audio and Video Service Assurance:

Huawei provides advanced mechanisms to ensure high-quality audio and video services in wireless networks, even under congestion.

Analysis of Each Statement:

Option A:This is incorrect. The correct default priority order isVI -> VO -> BE -> BK(Voice > Video > Best Effort > Background).

Option B:This is correct. Beacon frames can be used to instruct APs to suppress heavy-traffic users, ensuring fair resource allocation.

Option C:This is correct. Huawei's lab tests show that delays for voice and video services in congestion scenarios are56% lowerthan the industry average.

Option D:This is correct. The default scheduling priority order isVI -> VO -> BE -> BK.

Option E:This is incorrect. Heavy-traffic services are not automatically suppressed; suppression requires explicit configuration.

Conclusion:The correct statements are Options B, C, and D.
