質問 # 42
Which of the following are common terminal identification methods?
正解：A、B、C、D
解説：
All four options are recognized terminal identification methods. MAC OUI examines the first three bytes of a device's MAC address to determine its manufacturer, although it generally cannot identify the exact model or operating system. DHCP option identification analyzes fields such as DHCP options 12, 55, and 60, which can reveal the hostname, parameter-request list, vendor class, and other terminal characteristics. SNMP query is an active identification method that retrieves device details from relevant MIB objects and is particularly useful for printers, network devices, and other SNMP-capable equipment.
Nmap is also an active scanning method. It analyzes open ports, service responses, protocol behavior, and operating-system fingerprints to estimate a terminal's device type and OS. Huawei distinguishes information- reporting methods from proactive scanning methods: MAC OUI and DHCP options generally use information observed in traffic, whereas SNMP and Nmap actively query or scan the endpoint. iMaster NCE-Campus can correlate multiple fingerprints to improve identification accuracy and automatically apply terminal-specific access policies.

Which of the following Wi-Fi 7 APs offers PCIe card-based IoT functions?
正解：D
解説：
The AirEngine 6776I-X6TH is the model designed to provide PCIe card-based IoT expansion. The PCIe interface enables an appropriate IoT expansion card to be installed so that the AP can support additional wireless or sensing technologies according to the deployment requirement. This allows the same physical access infrastructure to deliver enterprise Wi-Fi and IoT connectivity.
The capability is useful in retail, healthcare, education, manufacturing, and asset-management environments, where technologies such as Bluetooth, RFID, Zigbee, electronic shelf labels, location services, or specialized sensing systems may need to coexist with the WLAN. A modular card design is preferable when an organization requires selectable or upgradeable IoT functions rather than only fixed integrated capabilities.
Huawei's Wi-Fi and IoT convergence architecture reduces repeated cabling, separate power systems, and independently managed wireless networks. It enables an IoT-capable AP to provide the installation position, power, management connectivity, and uplink data channel required by IoT modules. Among the models listed, the AirEngine 6776I-X6TH is the PCIe card-based IoT model. Therefore, option A is correct.
質問 # 44
Which of the following is not part of an IFIT measurement model?
正解：C
解説：
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.
質問 # 45
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?
正解：A
解説：
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.
質問 # 46
Which of the following models supports IPS, antivirus, and URL filtering at the same time?
正解：C
解説：
The AR5710-SE is the security-enhanced model that supports intrusion prevention, antivirus, and URL filtering concurrently. The "SE" variant is designed for branch scenarios requiring integrated routing and advanced security processing instead of only basic WAN connectivity and packet forwarding.
IPS examines network traffic for attack signatures and abnormal behavior and can block detected intrusions.
Antivirus inspection identifies malicious files or content using security-signature databases. URL filtering controls access to websites based on categories, reputation, or explicitly configured allowlists and blocklists.
Supporting all three functions simultaneously allows the AR5710-SE to operate as both an SD-WAN CPE and a secure branch egress gateway, reducing the requirement for an additional branch firewall.
Huawei's SD-WAN security architecture identifies firewall protection, antivirus, IPS, and URL filtering as its principal service-traffic security functions. Huawei also recommends advanced security functions such as URL filtering, IPS, and antivirus for branch scenarios requiring stronger Internet-egress protection. Among the listed models, the AR5710-SE provides the combined feature set. Therefore, option A is correct.
