質問 # 30
Which of the following statements is true about an AP's transmit power?
正解：C
解説：
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.
質問 # 31
An AP cannot work independently. Instead, it must be configured by a WAC or iMaster NCE-Campus.
正解：A
解説：
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.
質問 # 32
The CNN-based application identification technology can identify both known and unknown applications.
正解：B
解説：
The statement is true in the context of Huawei's AI-assisted application-identification architecture.
Conventional identification depends mainly on predefined signatures, fixed destination addresses, port numbers, protocol fields, DNS correlation, or deep packet inspection. Huawei's standard SD-WAN process uses Service Awareness and First-Packet Identification signature databases to identify and group application traffic. These mechanisms are effective for known applications but become less reliable when traffic is encrypted, applications change versions, or previously unseen applications appear.
A CNN-based classifier learns multidimensional traffic characteristics such as packet-length sequences, timing, direction, and flow behavior. It can classify traffic matching learned application patterns and, when implemented with open-set detection, recognize flows outside known classes as unknown or zero-day applications. Commercial-grade deep-learning traffic classification research demonstrates identification of known encrypted applications together with the handling of unknown zero-day applications.
This does not mean the system automatically assigns an exact commercial name to every unseen application.
It detects that the traffic does not match established classes so that it can be investigated, labelled, and incorporated into later model updates. Therefore, the statement is True.
質問 # 33
Which of the following statements are true about traffic encryption on SD-WAN links?
正解：B、D
解説：
Huawei SD-WAN allows encryption to be controlled by virtual network and by specific device relationships.
When encryption is enabled for a VN, the overlay data channels carrying that VN's traffic use IPsec protection across the relevant WAN links. This provides consistent isolation and confidentiality for the department or service represented by that VN.
Encryption can also be enabled between selected devices or sites. In that case, secure data channels are established for traffic exchanged between those specified endpoints, while other device relationships can continue using GRE without IPsec according to their policies.
Application-specific encryption, as described in option C, is not the supported control granularity. Application identification can influence intelligent traffic steering, QoS, and security-policy selection, but it does not mean that only the payload of a selected application is independently encrypted inside an otherwise unencrypted SD-WAN tunnel.
A transport network is an underlay WAN such as MPLS or the Internet. Enabling encryption is an overlay tunnel policy rather than a mechanism that encrypts all traffic belonging to an entire TN. Huawei distinguishes TNs as underlay networks and GRE or IPsec VPNs as overlay data channels. Therefore, only A and B are correct.
質問 # 34
Which of the following statements are true about wireless traffic forwarding modes on a fabric wireless network?
正解：A、B、C、D
解説：
All four statements correctly describe the trade-offs between direct and tunnel forwarding. With direct forwarding, an AP sends service traffic directly to the upstream network rather than encapsulating it in a CAPWAP data tunnel to the WAC. This eliminates unnecessary detours, avoids creating a WAC bandwidth bottleneck, reduces WAC load, and generally provides higher forwarding efficiency.
However, on a fabric network, Layer 3 roaming across different edge nodes may require the original edge or another designated device to remain the home agent. The resulting forwarding path and state synchronization can slightly affect roaming performance, making direct forwarding less suitable for extremely roaming- sensitive deployments. Huawei's material explains that after Layer 3 roaming in direct-forwarding mode, traffic may continue to be forwarded through the home agent.
Tunnel forwarding sends AP service traffic through CAPWAP tunnels to the WAC. This simplifies centralized policy enforcement, security control, and traffic management. Its disadvantage is that all wireless traffic may detour through the WAC, increasing forwarding pressure and potentially creating a performance bottleneck.
