NEW QUESTION # 17
Which of the following capabilities were introduced with Wi-Fi 7?
Answer: A,D
Explanation:
The capabilities introduced with Wi-Fi 7 are 4096-QAM and channel bandwidth of up to 320 MHz. Wi-Fi 7, based on IEEE 802.11be Extremely High Throughput, doubles the maximum channel width available under Wi-Fi 6 and Wi-Fi 6E from 160 MHz to 320 MHz where sufficient regulatory spectrum is available. It also introduces 4096-QAM, encoding 12 bits per modulation symbol compared with 10 bits for Wi-Fi 6's 1024- QAM. This can increase peak spectral efficiency when the signal-to-noise ratio is sufficiently high.
The other options were available before Wi-Fi 7. Support for up to eight spatial streams existed in earlier IEEE 802.11 generations, and MU-MIMO was already supported before Wi-Fi 7, with major uplink and downlink enhancements delivered by Wi-Fi 6. The 6 GHz band was commercially introduced through Wi-Fi
6E. Huawei's material specifically describes Wi-Fi 6E as extending Wi-Fi 6 into the 6 GHz spectrum. Wi-Fi 7 continues using 6 GHz but did not introduce it. Therefore, only A and C are correct.
NEW QUESTION # 18
The AirEngine 8771-X1T has dynamic-zoom smart antennas that can switch between omnidirectional and high-density modes.
Answer: A
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 # 19
Which of the following statements is false about GRE over IPsec?
Answer: D
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 # 20
iMaster NCE-Campus can be installed in an environment where a third-party server, VMware, and SUSE are deployed.
Answer: A
Explanation:
The statement is true. iMaster NCE-Campus supports multiple on-premises deployment combinations rather than being restricted exclusively to Huawei-branded physical servers and Huawei virtualization platforms.
The training material explicitly lists physical-server deployment using SUSE Linux and a third-party server, as well as virtual-machine deployment using VMware.
The platform can also be deployed using Huawei server and virtualization combinations, including Huawei
2288X servers, EulerOS, FusionCompute, and TaiShan-based environments. The availability of several combinations enables customers to select an architecture consistent with their existing data-center standards, procurement strategy, virtualization environment, and operational requirements.
Huawei nevertheless identifies a recommended platform combination in the training material. A recommendation does not mean that the other listed combinations are unsupported; it identifies the preferred configuration for standardized deployment and support. The material displays third-party server plus SUSE Linux and VMware-based virtual-machine deployment as valid alternatives while recommending Huawei
2288X V5 plus EulerOS.
The deployment must still satisfy the specified CPU, memory, storage, network-interface, software-version, and compatibility requirements. Therefore, the statement is True.
NEW QUESTION # 21
Which of the following statements is false?
Answer: C
Explanation:
Option C is false. Traditional QoS can classify traffic and provide differentiated treatment for service categories such as voice, video, and ordinary data. It normally performs classification, marking, policing, shaping, congestion avoidance, and queue scheduling on an interface. This provides service-level differentiation but does not deliver sufficiently refined simultaneous management across multiple users and multiple applications.
Huawei's material explicitly states that traditional QoS schedules traffic based on port bandwidth and can differentiate traffic according to service levels, but it is difficult to distinguish traffic by user. It also states that traditional QoS cannot manage and schedule traffic from multiple services and multiple users simultaneously.
HQoS addresses this limitation through hierarchical, multi-level queues. For example, a parent level can allocate bandwidth to departments, VPNs, sites, or users, while child queues prioritize applications such as voice, video, email, and best-effort traffic. Huawei describes HQoS as hierarchical scheduling that differentiates both services and users. Therefore, statements A, B, and D are correct, while statement C incorrectly attributes an HQoS capability to traditional QoS.
