The correct answer is D. 71W . PoE++ is associated with the IEEE 802.3bt standard, which extends earlier PoE and PoE+ power delivery capabilities to support higher-power devices. In engineering practice, IEEE 802.3bt Type 4 PSE output power is generally recognized as being around 71 W at the source side, which is why 71 W is the best answer here. This aligns with the training material’s device-side description that the PowerCube service board includes ports where “two of the ports can be used to transmit P & E++ signals” while other ports transmit lower-level P & E signals

From a deployment perspective, this higher power class is important because intelligent vision sites may need to power cameras, illuminators, communication modules, and related edge equipment over Ethernet-linked interfaces. The lower values in the options correspond to earlier or lower-power classes: 15.4 W is associated with standard PoE, 30 W with PoE+, and 50 W is below the typical maximum associated with full 802.3bt Type 4 sourcing. Therefore, 71 W is the correct ceiling among the provided choices.

The correct answers are A, C, and D because cloud-edge synergy is defined as collaboration between a central platform and lightweight edges or other upper- and lower-level cloud domains. The material states that “Cloud-edge synergy: collaboration between the central platform and lightweight edges or other upper- and lower-level domains deployed on clouds” while separately identifying “Multi-camera Collaboration: Multiple cameras collaborate to identify same image” . This distinction is decisive: option B belongs to multi-camera collaboration, not cloud-edge synergy.

In practical JVS deployment, cloud-edge synergy includes centralized task orchestration, algorithm lifecycle management, and cross-domain resource coordination. That is why delivering vehicle alert tasks downward to lower-level platforms fits the model, and why centrally loading, upgrading, or replacing algorithms on upper- and lower-level platforms also fits. Likewise, when the upper-level platform applies for edge-side resources to perform intelligent analysis on video or images, it is using distributed resource collaboration, which is a classic cloud-edge function. Option B is excluded because it describes camera-to-camera cooperative recognition rather than platform-to-edge coordination. Therefore, the valid cloud-edge synergy scenarios are A, C, and D .

The Cloud Service Platform (CSP) is the underlying infrastructure that manages containers, resources, and services for the intelligent vision platform. Routine maintenance and health checks are essential to ensure the continuous availability of video surveillance services. A comprehensive routine check of the CSP encompasses multiple layers of the system architecture.

First, the License status must be verified to ensure that all intelligent functions and channel capacities remain authorized and active. Second, monitoring CPU and memory usage is critical to identify potential resource bottlenecks that could lead to service instability or video stuttering. Third, for systems deployed in high-availability environments, the Cluster running status (including two-node cluster heartbeat and synchronization) must be checked to ensure failover capabilities are intact. Finally, since the platform utilizes a microservice architecture, checking the CSP and container running status is mandatory to verify that all functional modules (like the VCNAPI or BMU) are active and isolated as intended. By performing these checks regularly, administrators can proactively address issues before they trigger critical system alarms or data loss.
