질문 # 11
The CNN-based application identification technology can identify both known and unknown applications.
정답：B
설명：
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.
질문 # 12
Huawei provides an innovative technology that can maintain smooth video when traffic packet loss between enterprise branches reaches up to 20%. Which technology provides this capability?
정답：B
설명：
A-FEC, or Adaptive Forward Error Correction, is the correct technology. It protects delay-sensitive traffic by adding calculated redundant packets to the original packet stream. If some original packets are lost during WAN transmission, the receiving edge device can reconstruct them using the surviving original and redundant packets rather than waiting for end-to-end retransmission.
The key distinction between ordinary FEC and A-FEC is adaptation. With A-FEC, the receiving device reports real-time packet-loss and continuous-loss information to the transmitting device through FEC acknowledgement messages. The transmitting edge then dynamically increases or decreases the redundancy ratio according to actual network conditions. This provides stronger recovery during severe loss while avoiding unnecessary bandwidth overhead when link quality improves. Huawei describes this feedback- controlled adjustment as a mechanism that can alleviate or eliminate the impact of packet loss.
IFIT and IPCA are primarily measurement and service-quality analysis technologies; they do not reconstruct lost video packets. Fixed FEC does not adapt its redundancy level as effectively to changing loss conditions.
Therefore, the technology intended for smooth video under packet loss of up to 20% is A-FEC.
질문 # 13
On a large campus network, inter-WAC roaming should be avoided as much as possible to ensure the roaming experience.
정답：B
설명：
The statement is true as a WLAN design recommendation. Inter-WAC roaming is supported, but it introduces more control-plane interaction and forwarding complexity than intra-WAC roaming. The Home WAC and Foreign WAC must belong to the same mobility group, synchronize station and AP information, and establish an inter-WAC CAPWAP tunnel for control information and, in some scenarios, service forwarding.
Additional synchronization, tunnel processing, route handling, and failure dependencies can increase roaming delay and complicate troubleshooting. This is especially relevant for delay-sensitive applications such as voice, video, automated guided vehicles, and real-time production systems. A better design places APs between which users frequently move under the same WAC wherever controller capacity and physical topology permit.
Avoiding inter-WAC roaming does not mean disabling the function entirely. Large campuses may require multiple WACs for scale, redundancy, or geographic distribution. Mobility groups should still be configured for unavoidable cross-controller movement. However, buildings, floors, and continuous roaming areas should be assigned carefully so that normal roaming remains intra-WAC. Therefore, the recommendation in the statement is correct, and the answer is True.
질문 # 14
Which of the following statements is false?
정답：C
설명：
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.
질문 # 15
Which of the following deployment modes are supported by APs?
정답：A,B,C
설명：
APs support barcode scanning through the CloudCampus APP, DHCP Option 148-based deployment, and deployment through Huawei's registration query center. With barcode scanning, the installer scans the AP's label using the CloudCampus APP. The application obtains information such as the electronic serial number and MAC address, associates the AP with the correct tenant and site, and allows the AP to register with iMaster NCE.
With DHCP Option 148, the DHCP server supplies the AP with its IP configuration and the IP address and port number of iMaster NCE. The AP changes to cloud-management mode and automatically initiates registration. Huawei lists AR routers, switches, and APs as supported devices for this mode.
The registration query center can also provide the controller address after the AP contacts Huawei's query service. It supports APs together with ARs, firewalls, and switches. Email-based deployment is primarily an SD-WAN CPE or AR-router ZTP method, not an AP deployment mode. Therefore, A, C, and D are correct.
