Which of the following statements is false about GRE over IPsec?
正解：D
解説：
Option B is false because it reverses the encapsulation behavior. In IPsec transport mode, the IPsec security header is inserted after the existing IP header; a new outer IP header is not normally added. In tunnel mode, the complete original IP packet is encapsulated and a new outer IP header is added. Tunnel mode therefore generally introduces greater overhead and produces a longer packet than transport mode, not the reverse.
The remaining statements are correct. IPsec supports both transport and tunnel modes. GRE over IPsec performs GRE encapsulation first, allowing GRE to transport the original payload, and then applies IPsec protection to the resulting GRE packet. The IPsec security association is established between the GRE tunnel endpoints, protecting the GRE-encapsulated traffic as it traverses an untrusted transport network.
Huawei SD-WAN data channels can use either GRE or GRE over IPsec. GRE provides flexible overlay encapsulation, while IPsec adds confidentiality, integrity, origin authentication, and anti-replay protection for site-to-site traffic. Huawei specifically identifies IPsec encryption as the mechanism securing site-to-site SD- WAN services.

How many ports can a 400GE card offer on the CloudEngine S16700 series next-generation flagship core switches?
正解：D
解説：
A high-density 400GE service card for the CloudEngine S16700 series can provide 18 ports. The S16700 is positioned as a next-generation flagship campus core switch designed for ultra-high-capacity aggregation, large-scale Wi-Fi backhaul, data-center interconnection, and long-term bandwidth evolution.
An 18-port 400GE card provides a theoretical aggregate port rate of 7.2 Tbit/s in each direction before considering the switching fabric's internal architecture and forwarding design. This density allows a single chassis slot to aggregate numerous high-speed distribution switches, connect multiple campus fabrics, or provide high-bandwidth links toward data centers and service platforms. It also reduces the number of cards and chassis required compared with lower-density 8-port, 12-port, or 16-port alternatives.
The question asks specifically for the number of physical 400GE interfaces offered by the card, not the entire chassis capacity or the number of ports after breakout. Under the H19-404 product-portfolio specification represented by this question, the correct density is 18 native 400GE ports. Therefore, option B is correct.
質問 # 14
What is the function of the PROFINET DCP?
正解：B
解説：
PROFINET DCP, meaning Discovery and Basic Configuration Protocol, is used during device discovery and initial network configuration. It operates at the data-link layer and enables an engineering station or PROFINET IO controller to locate devices on the local Ethernet segment, identify them by MAC address or station name, assign a PROFINET device name, and configure IP parameters such as the IP address, subnet mask, and default gateway.
DCP is therefore not responsible for normal cyclic process-data exchange. Real-time PROFINET communication performs that function after the controller and I/O device have been configured and an application relationship has been established. Alarm exchange and acyclic parameterization are also handled through other PROFINET communication relationships and services.
The distinction matters during commissioning. A new I/O device may initially have no usable IP configuration. DCP allows the controller or engineering tool to discover it at Layer 2 and provision the identity and addressing information required before higher-layer communication can begin. PROFINET documentation identifies DCP as mandatory for assigning IP addresses and configuring station names on the local network.
質問 # 15
In the High-Quality 10 Gbps Campus Network Solution, which of the following experiences is improved by iMaster NCE-Campus?
正解：B
解説：
iMaster NCE-Campus primarily improves the operations and maintenance experience in this solution. It provides centralized planning, deployment, configuration, policy orchestration, monitoring, topology management, device management, alarm handling, and maintenance through a unified graphical interface.
Instead of configuring each switch, AP, WAC, firewall, or router separately, administrators can define services and policies centrally and deliver them across the network. Huawei states that iMaster NCE-Campus provides integrated LAN and WAN management, integrated deployment, integrated policies, and integrated O
& M, thereby improving deployment and O & M efficiency. It also provides network monitoring, service alarms, file management, log management, device maintenance, user management, and virtual-network management from one platform.
Wireless, wired, and application experience analysis is more directly associated with iMaster NCE- CampusInsight, which uses telemetry, AI, protocol tracing, and predictive analysis to quantify user and application experience. iMaster NCE-Campus serves as the management and control platform that simplifies administrators' daily work. Therefore, the experience specifically improved by iMaster NCE-Campus is the O
& M experience, making option C correct.
質問 # 16
Which of the following statements is false about the energy-saving function of the digital map?
正解：B
解説：
Option C is false. The digital-map energy-saving function provides network-wide energy visibility, identifies periods of low wireless demand, and recommends appropriate energy-saving time windows. During an approved energy-saving period, selected wireless APs or radio resources can be placed into an energy-saving state after the system evaluates coverage, traffic, and capacity requirements.
Automatically powering off switches is not the intended function. Campus switches may carry essential wired services, provide uplinks for other network devices, and supply PoE power to APs, cameras, phones, sensors, and access-control systems. Automatically shutting down a complete switch could therefore interrupt many unrelated services and potentially disconnect downstream network segments.
Huawei identifies low-carbon and energy-saving operation as a characteristic of cloud campus networks and combines this objective with AI-based intelligent O & M and proactive optimization. Its intelligent O & M architecture analyzes AP load trends and performs predictive wireless-network optimization, providing the analytical foundation for selecting safe energy-saving periods and resources.
Therefore, A, B, and D describe supported digital-map energy-saving capabilities. Automatic switch power- off is the false statement, making C correct.
