NEW QUESTION # 11
Which of the following statements is true about an AP's transmit power?
Answer: A
Explanation:
An AP's transmit power must be maintained within an appropriate range. Excessive power does not automatically improve service quality. A high-power AP can enlarge its interference domain, create co- channel or adjacent-channel interference, produce asymmetric uplink and downlink coverage, and cause sticky-client behavior because a station continues hearing an AP even when its weaker transmission cannot reliably reach that AP. Huawei states that high-power APs can interfere with adjacent APs and that radio calibration dynamically adjusts AP channels, power, and frequency bands to ensure coverage while minimizing interference.
Conversely, power that is too low creates coverage holes, weak received signal strength, low modulation rates, retransmissions, and roaming instability. When a new AP is added, neighboring APs may reduce their transmit power to limit interference. When an AP goes offline, neighboring APs may increase power to compensate for the missing coverage. The engineering objective is therefore neither maximum nor minimum power, but sufficient coverage with controlled overlap and minimum interference. Accordingly, option B is correct.
NEW QUESTION # 12
An AP cannot work independently. Instead, it must be configured by a WAC or iMaster NCE-Campus.
Answer: A
Explanation:
The statement is false because "AP" is a generic term covering several operating architectures. A Fit AP requires a WAC, and a cloud-managed AP is centrally managed through iMaster NCE-Campus. However, a Fat AP is autonomous: it can operate and be configured independently without a centralized controller.
Huawei also describes the leader AP architecture, in which a capable AP integrates part of the WAC functionality, operates independently, and manages a limited number of Fit APs.
Therefore, the absolute claim that an AP cannot work independently is technically incorrect. The correct interpretation depends on the AP mode. Fit APs depend on a WAC or leader AP for centralized configuration and CAPWAP-based management, whereas Fat APs provide local control and forwarding. Huawei explicitly states that the Fat AP architecture is autonomous and requires no additional centralized control device.
Because at least one recognized AP architecture operates independently, the correct answer is False.
NEW QUESTION # 13
Which of the following statements is false about GRE over IPsec?
Answer: C
Explanation:
Option B is false because it reverses the encapsulation behavior. In IPsec transport mode, the IPsec security header is inserted after the existing IP header; a new outer IP header is not normally added. In tunnel mode, the complete original IP packet is encapsulated and a new outer IP header is added. Tunnel mode therefore generally introduces greater overhead and produces a longer packet than transport mode, not the reverse.
The remaining statements are correct. IPsec supports both transport and tunnel modes. GRE over IPsec performs GRE encapsulation first, allowing GRE to transport the original payload, and then applies IPsec protection to the resulting GRE packet. The IPsec security association is established between the GRE tunnel endpoints, protecting the GRE-encapsulated traffic as it traverses an untrusted transport network.
Huawei SD-WAN data channels can use either GRE or GRE over IPsec. GRE provides flexible overlay encapsulation, while IPsec adds confidentiality, integrity, origin authentication, and anti-replay protection for site-to-site traffic. Huawei specifically identifies IPsec encryption as the mechanism securing site-to-site SD- WAN services.
NEW QUESTION # 14
The AirEngine 8771-X1T has dynamic-zoom smart antennas that can switch between omnidirectional and high-density modes.
Answer: B
Explanation:
The statement is true. The AirEngine 8771-X1T uses dynamic-zoom smart-antenna technology that can adapt its radiation characteristics according to the deployment environment. In omnidirectional mode, the antenna pattern is optimized to provide broad and balanced coverage, making it appropriate for ordinary offices, corridors, classrooms, and other environments where users are distributed over a relatively large area.
In high-density mode, the antenna pattern is adjusted to concentrate radio energy more effectively within the intended service area. This reduces unnecessary signal leakage, limits interference between neighboring APs, and improves concurrent-user performance in lecture halls, conference rooms, auditoriums, and similar high- density environments.
The switching capability is more effective than using a permanently fixed antenna pattern because WLAN conditions can change as users move and traffic density increases or decreases. Huawei's training material states that dynamic-zoom smart antennas dynamically switch between omnidirectional and high-density modes, improving coverage in omnidirectional mode while strengthening the user experience in high-density scenarios. Therefore, option A is correct.
NEW QUESTION # 15
Which of the following is not part of an IFIT measurement model?
Answer: D
Explanation:
The Network Management System is not an element of the IFIT measurement model. An IFIT measurement definition identifies the traffic to be measured, the locations where measurement actions occur, and the direction in which the flow is evaluated. The measurement flow specifies the target packets, usually through flow-identification fields. Measurement points define where packets are marked, counted, timestamped, or reported, such as ingress, transit, and egress nodes. Measurement direction distinguishes forward and reverse monitoring so that packet loss, delay, and path behavior can be analyzed correctly for each direction.
An NMS or controller remains operationally important because it creates measurement tasks, distributes configurations, receives telemetry data, correlates the results, and presents fault-location information.
However, it is the management and analysis system surrounding the measurement model, not one of the model's constituent measurement parameters.
Huawei positions IFIT as a high-precision telemetry mechanism used to delimit and locate application-quality faults. The training material highlights IFIT's capability to locate faults rapidly and detect packet loss with extremely high reliability. Therefore, the component that is not part of the measurement model is the NMS.
