質問 # 52
A label stack is an ordered set of labels. MPLS supports a maximum of three layers of nested labels.
正解：A
解説：
The statement is false. An MPLS label stack is an ordered sequence of label-stack entries, with the top label processed first and the bottom identified by the Bottom-of-Stack bit. However, the MPLS architecture does not define a universal maximum of three nested labels. An MPLS forwarding operation may replace the top label, remove it, or push one or more additional labels onto the stack.
Practical label depth is constrained by device implementation, forwarding ASIC capabilities, packet size, and the number of network functions being encoded. A conventional MPLS VPN may use two labels: a transport label and a VPN label. More advanced deployments can add labels for traffic engineering, segment routing, entropy, service chaining, or hierarchical transport. This can produce stacks deeper than three entries.
Therefore, "three layers" may describe a limitation of a particular platform, software version, or deployment design, but it is not an MPLS protocol maximum. RFC 3032 defines the stack as a sequence of four-byte entries and explicitly allows one or more entries to be pushed without specifying a three-label ceiling.
質問 # 53
In the energy-saving solution based on AI traffic prediction, IoT APs are recommended to operate in non- energy-saving mode by default.
正解：A
解説：
The statement is true. AI-based energy-saving systems analyze historical traffic and usage patterns to predict periods of low network demand. Ordinary AP radios or access devices can then enter an energy-saving state when their capacity is not required, while surrounding devices maintain sufficient coverage and service availability.
IoT APs, however, may host continuously operating IoT cards, sensors, electronic shelf-label services, Bluetooth location functions, RFID services, healthcare devices, or asset-tracking terminals. Placing such an AP into an energy-saving or hibernation state could interrupt more than ordinary Wi-Fi connectivity. It could also disable an IoT module's power supply, management channel, data backhaul, or persistent sensing function. Huawei's Wi-Fi and IoT convergence architecture uses APs as shared locations, power sources, and communication channels for IoT services.
Huawei also applies intelligent technologies to analyze AP load trends and perform predictive network optimization. The safer default is therefore to exclude IoT APs from automatic energy-saving actions unless the administrator confirms that their attached IoT services tolerate interruption. Accordingly, the answer is True.
質問 # 54
Which of the following are WAN interconnection models for multi-branch campus networks?
正解：A、C、D
解説：
Huawei SD-WAN supports full-mesh, hub-spoke, and partial-mesh interconnection models. In a full-mesh topology, every site can communicate directly with the other sites. This model minimizes intermediate forwarding and is appropriate when branches frequently exchange latency-sensitive traffic such as voice, video, or collaborative application data.
In a hub-spoke topology, branch sites communicate with a central headquarters or data-center hub. Branch-to- branch traffic normally traverses that hub. The model is simple, scalable, and suitable for enterprises whose applications and shared resources are concentrated at headquarters.
Partial-mesh is used when most sites can communicate directly but some sites lack direct underlay connectivity or do not require direct tunnels. Those sites can communicate through a redirect or intermediate site. Huawei describes full-mesh, hub-spoke, and partial-mesh as supported topology designs and explains the role of a redirect site in partial-mesh networking.
"Partial-spoke" is not a defined SD-WAN topology model. A spoke is a role within hub-spoke networking rather than an independent partial-spoke topology. Therefore, A, B, and D are correct.
質問 # 55
Which of the following statements are true about selecting network access authentication points?
正解：A、C、D
解説：
Authentication points should generally be placed on access devices close to the terminals. For wireless users, the AP or WLAN access device is the natural admission point because it directly controls the station's wireless association and service access. For wired users, the access switch directly connects the endpoint and can enforce 802.1X, MAC-address authentication, VLAN authorization, ACLs, and security-group policies.
Huawei recommends access devices as authentication points for employees and specifically recommends access switches as authentication points for wired dumb terminals using MAC-address authentication.
Deploying enforcement close to endpoints prevents unauthenticated or unauthorized traffic from traversing deeper into the campus network. It also improves fault isolation, policy granularity, and scalability because admission processing is distributed across access devices.
Option A is incorrect. A centralized authentication point can simplify configuration and policy management, but it does not inherently provide higher performance. It can create concentrated processing pressure, enlarge the Layer 2 scope, and allow unauthenticated traffic to travel farther before being evaluated. Therefore, the recommended principles are represented by B, C, and D.
質問 # 56
