質問 # 26
Which of the following WLAN networking solutions is recommended when there are 15,000 wireless terminals on the customer network?
正解：B
解説：
A network serving 15,000 wireless terminals is a large-scale WLAN and should use a standalone WAC solution. A dedicated WAC provides independent controller resources, scalable AP and user management, centralized WLAN policy control, and the ability to deploy controller redundancy without tying wireless- control capacity directly to a specific core-switch service card.
Huawei recommends a standalone WAC when the wireless network scale is large or when the wireless network is deployed independently over an existing wired campus. The WAC is typically connected to the aggregation or core layer in off-path mode, and VRRP hot standby can be used to improve reliability.
Native WAC solutions are valuable for unified wired and wireless management, authentication, forwarding, and policy enforcement. However, for a very large number of wireless terminals, the controller platform must be selected according to user, AP, traffic, and forwarding-capacity specifications. A standalone WAC allows the wireless control plane to be sized and expanded independently.
Option C provides the dedicated WAC together with the required core and aggregation or access infrastructure. Therefore, it is the recommended architecture for 15,000 wireless terminals.
質問 # 27
Which of the following functions is supported by the AR6177?
正解：D
解説：
The distinguishing function supported by the AR6177 is VDSL. VDSL, or Very-high-bit-rate Digital Subscriber Line, enables a branch router to obtain WAN connectivity over existing copper telephone infrastructure. It is appropriate for small branches and distributed sites where Ethernet private lines, fiber, or mobile connections are unavailable or commercially impractical.
The AR6177 can terminate the VDSL access circuit and provide routing, NAT, DHCP, VPN, and other branch-gateway functions for the connected LAN. In this single-answer question, Wi-Fi and PoE are not the defining integrated capabilities of the AR6177 model. Similarly, the complete combination of IPS, antivirus, and URL filtering belongs to a security-enhanced product profile rather than the function used to distinguish the AR6177.
Huawei's campus design material recognizes DSL links as a specific WAN-access category and notes that deployments involving complex or low-speed links, including DSL, may require an appropriate branch-device deployment method. The model is therefore selected when direct VDSL-based WAN access is required.
Consequently, VDSL is the supported capability intended by this question, and option C is correct.
質問 # 28
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.
質問 # 29
Which of the following statements are true about predefined security zones on a firewall?
正解：B、C、D
解説：
Huawei firewalls provide four commonly predefined security zones: Local, Trust, DMZ, and Untrust. The Local zone represents the firewall itself, including traffic generated by or destined for the device, and has the highest default security priority of 100. The Trust zone normally represents an organization's protected internal network and has a default priority of 85, not 95. Therefore, option C is false.
The DMZ typically hosts public-facing or semi-trusted resources, such as web, email, and application servers.
Its default priority is 50, placing it between the trusted internal network and the external untrusted network.
The Untrust zone normally represents the Internet or another uncontrolled network and has the lowest predefined priority of 5.
Zone priority expresses the relative security level used to classify inbound and outbound traffic direction; it does not independently permit traffic. Security policies still determine whether matched traffic is allowed or denied. Huawei's SD-WAN design uses Trust and Untrust zones on CPEs, and iMaster NCE can orchestrate the corresponding zones and firewall policies for Internet-access protection.
質問 # 30
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?
正解：A
解説：
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.
