The correct answers are A, C, and D . In IVS3800 architecture, the distinction between management nodes and service nodes is based on whether the node carries the platform’s management container set, especially the CSPOM role. A management node is the server that contains the management component, while a service node is the server that does not contain that management component and instead focuses on service workloads. This is why C and D are correct from the node-role definition perspective.

The cluster nature of the management role is also consistent with the platform design. The training material repeatedly refers to BMU and management addressing in two-node cluster mode , for example: “If the BMU is deployed in two-node cluster mode, enter the external service floating IP address of the BMU” and similarly references external management floating IP handling for clustered upper-level nodes . This reflects that the management layer is designed around clustered high-availability deployment, supporting A . By contrast, B is not accepted because an IVS3800 system made up of only management nodes would lack the service-bearing nodes needed to deliver actual intelligent vision workloads. Therefore, A, C, and D are the correct statements.

Cloud service network → The IVS1800 connects to the HUAWEI CLOUD service platform over the Internet and allows you to manage devices on the mobile app.

Network for connecting the device to the upper-level video and image management platform → The IVS1800 connects to the IVS3800 platform as an NVR.

Multi-node network → You can manage multiple IVS1800s on the iClient.

Single-node network → The IVS1800 can connect directly to a monitor, using an HDMI cable, to display live or recorded video.

The matching is based on the deployment role of each IVS1800 network type. The cloud service network is the mode used when the IVS1800 connects outward through the Internet to Huawei cloud services for remote device management, so it matches the feature about connection to the HUAWEI CLOUD service platform and mobile-app management. The network for connecting the device to the upper-level video and image management platform is the upstream integration path used when the IVS1800 works under a larger platform such as the IVS3800 , so that feature matches the statement about connecting to the IVS3800 platform as an NVR .

The multi-node network is intended for centralized management of multiple IVS1800 devices, which is why it matches the feature stating that multiple IVS1800s can be managed on the iClient . The single-node network is the standalone deployment model, so it matches the feature where the IVS1800 connects directly to a monitor through HDMI for local live or playback display. This mapping follows the standard Huawei deployment logic of standalone, clustered, upstream-integrated, and cloud-managed operation.

The physical design of a data center for intelligent vision systems involves strategic placement of network switches to optimize cabling and performance. Two common architectures are Top of Rack (TOR) and End of Row (EOR). In a TOR deployment, Top of Rack (TOR) switches are deployed on the top of each cabinet and used for communication between servers in each cabinet and the external network . This approach minimizes the length of copper cabling within the rack and simplifies the expansion of individual cabinets.

Conversely, the EOR architecture centralizes the switching infrastructure. In this setup, End of Row (EOR) switches are deployed in the last cabinet at each row, and servers in all cabinets at each row are connected to switches through horizontal cabling . While EOR can simplify management by centralizing hardware, it requires significant horizontal cabling across the row. Huawei’s IVS planning recommendations specify that the management port and service ports of hardware devices (like the Taishan 200) connect to these switches. Specifically, the "Management TOR" handles the management plane (often using CE5800 series), while the "Service TOR" handles the high-bandwidth 10 GE service plane (often using CE6800 series), with both eventually aggregating through the EOR switch to connect to the wider customer network.
