問題 #59
Which of the following statements is false?
答案：C
解題說明：
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.
問題 #60
Which solution can be used when users need to centrally control and manage Internet access traffic but do not have the required security-processing capability?
答案：C
解題說明：
Professional security devices should be deployed at the headquarters or another centralized Internet-access site. Under centralized Internet access, branch Internet traffic is first carried through the SD-WAN overlay to the centralized gateway. The headquarters security infrastructure then performs access control and security inspection before forwarding the traffic to the Internet.
This approach is appropriate when branch CPEs lack sufficient processing capacity or advanced security functions. A centralized firewall or dedicated security platform can provide intrusion prevention, antivirus inspection, URL filtering, application control, content security, and unified logging. It also allows the enterprise to enforce one consistent security policy instead of maintaining separate advanced configurations at every branch.
Deploying advanced security capabilities on each CPE, as proposed in option C, is a distributed local- breakout design and does not satisfy the stated limitation concerning security-processing capability. Third- party cloud security services can be used in some site-to-cloud or secure Internet-access architectures, but they are not the intended headquarters-based centralized solution in this question.
Huawei explicitly states that centralized Internet traffic is diverted to the centralized access site and that the firewall function is deployed there to secure Internet services. Therefore, option D is correct.
問題 #61
An AP cannot work independently. Instead, it must be configured by a WAC or iMaster NCE-Campus.
答案：A
解題說明：
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.
問題 #62
Which of the following deployment modes are supported by APs?
答案：A,B,D
解題說明：
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.
問題 #63
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?
答案：D
解題說明：
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.
