The correct answer is D because the iris directly controls the amount of light entering the lens, which has the most immediate effect on image brightness. When the iris opening is enlarged, more light reaches the image sensor, and the captured image becomes brighter. This makes iris adjustment the preferred action when the goal is simply to improve overall brightness. By contrast, resolution affects image detail, not light intake. Angle of view changes scene coverage, not exposure level. Focal length changes magnification and framing, but it does not function as the primary exposure control in this context.

This aligns with the exposure-centered logic emphasized throughout the training material, where Huawei highlights advanced imaging control and notes that “T-Shot, Huawei’s patented exposure technology, enables optimal imaging of targets and vehicles at the same time” and that traditional exposure methods cannot properly expose different targets in one image . In practical camera operation, brightness problems are first treated as an exposure issue, and among the listed options, the iris is the only parameter that directly regulates exposure by controlling incoming light.

The correct answer is A because video site planning follows a logical engineering sequence: first determine where the site should be deployed, then perform a detailed site survey , and finally complete device selection planning based on the confirmed environmental and construction conditions. The material first lists typical site selection targets such as “Road intersections and entrances and exits” and “Key areas in cities” , which clearly corresponds to site selection planning. It then moves into survey items such as “Environment survey” , “Power supply” , and “Construction conditions” , showing that the survey is performed after the preliminary site location is determined and before final device planning is completed

This sequence is consistent with actual project practice. A project team cannot choose appropriate poles, anti-corrosion levels, cameras, power schemes, or transmission methods until the physical environment has been checked. For example, the survey determines whether the site is near the sea, whether mains power is stable, and whether enough construction space is available. Those findings directly affect the final device model and solution design. Therefore, the correct process is video site selection planning → video site survey → video site device selection planning .

Video structuring is the essential process of converting unstructured video content into searchable, organized data. This capability is integrated across the Huawei Intelligent Vision architecture, existing at both the front-end (cameras) and the back-end (platforms). Huawei's Software-Defined Cameras (SDC) are equipped with professional AI chips, such as the Ascend 310 or Hi3559A, which provide the high-performance processing required to perform this task locally. These AI chips can even replace backend servers to structure full video features, maximizing network-wide intelligent analysis efficiency. By performing structuring at the edge, the system reduces the bandwidth required to transmit full video streams to the central cloud while maintaining real-time awareness.

Simultaneously, Huawei’s intelligent video cloud and big data platforms provide robust back-end structuring capabilities for historical or live video analysis. These platforms utilize advanced algorithms to automatically generate structured data from massive video feeds. As noted in the documentation, video search intelligently analyzes unstructured original video data and automatically generates structured data based on the proper algorithms. This dual-layer approach allows for flexible deployment depending on whether real-time edge processing or high-volume centralized analysis is required for a specific security scenario.

Camera cycling, also known as round-robin viewing, is a feature in the intelligent vision system that allows a set of video panes to automatically rotate through different camera feeds at a specified interval. This is a common practice in security monitoring rooms to allow a limited number of monitors to cover a much larger number of cameras.

According to the system logic for the iClient and IVS platform, the cycling function is designed to refresh the content of the active panes. If the number of cameras selected is equal to or less than the number of available video panes, the display remains static because every camera can be shown simultaneously without the need for rotation. To trigger the "cycling" mechanism, the number of cameras in the resource group must exceed the number of panes currently displayed on the screen. Therefore, if you have configured six video panes for camera cycling, you need to select at least 7 cameras so that the system has a "surplus" camera to rotate into one of the panes when the interval timer expires. This ensures that the surveillance personnel see every camera in the group over a period of time, fulfilling the purpose of the round-robin service.

The correct answer is B. FALSE . The installation guidance for strobe lights in the material focuses on orientation and illumination angle , not on a fixed rule that they must be installed on both sides of the checkpoint camera and more than 2 meters away. The document states that “Strobe light: provides light compensation at night to clearly capture license plates and pedestrians” and further emphasizes that “The strobe light and flash light cannot be installed upside down. The cable outlet must be vertically at the bottom” and “It is recommended that a certain angle be formed between the strobe light or flash light and the lane to avoid excessive exposure of license plates caused by direct illumination”

This means the critical design requirement is to avoid direct reflective glare and overexposure by controlling the installation angle relative to the lane. The statement in the question adds rigid conditions such as both sides installation and a distance of more than 2 m , but those are not established in the cited training guidance. Since the PDF does not define those conditions as universal requirements, the statement is inaccurate as written.

The correct answer is C because the described method exactly matches the definition of horizontal projection used in license plate character area extraction. In license plate recognition, projection methods are commonly used to separate valid character regions from noise and borders. The material states that “Horizontal projection: The binary license plate image is horizontally projected along the Y axis to obtain the longest successive projection segment as the character area. Filter out horizontally successive black lines around the license plate.” This wording is essentially identical to the question, so the method can be identified directly.

From an image-processing perspective, horizontal projection analyzes the pixel distribution across rows to locate the effective vertical range of the character band. This helps remove irrelevant black border lines above and below the plate characters. By contrast, vertical projection is mainly used later to segment individual characters because spaces naturally exist between them. Binary processing is a preprocessing step, not the named segmentation method here, and direction division is not the correct technical term in this context. Therefore, the only correct choice is C. Horizontal projection .

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.

The correct answer is C because the Kunpeng processor is characterized by ARM-based RISC design, multi-core capability, low power consumption, and high integration, but not by a closed architecture . The material describes Kunpeng’s strengths by stating that “The ARM architecture is used so that the same function performance occupies a smaller area of the chip, consumes less power, and are highly integrated. More hardware CPU cores are provided for better concurrent processing” and further notes that “The RISC instruction set is used. The instruction length is fixed, the addressing mode is flexible and simple, and the execution efficiency is high” . These statements directly support options A, B, and D .

From an engineering perspective, ARM-based processors are known for compact instruction design, strong concurrency through many CPU cores, and high performance per watt. Those are exactly the attributes highlighted here. By contrast, “closed architecture” is not presented as a Kunpeng feature in the training material and does not align with Huawei’s ecosystem positioning, which emphasizes compatibility across multiple operating systems and application scenarios from IoT to cloud. Therefore, C is the only option that does not describe the Kunpeng processor.

The correct answer is A. TRUE . In IVS3800 and Lite Edge network construction, the service plane relies on TOR switching for high-bandwidth service traffic, and link bundling is a standard design approach to provide bandwidth aggregation and redundancy. The material identifies the service-plane access layer explicitly: “Service TOR: TOR access switch on the service plane. The 10 GE optical port or GE port on the service plane is connected to the switch. CE6800 series switches are recommended” . This directly confirms that service TOR switches are a required part of the service-plane topology.

In practical Huawei data-center-style deployment, when multiple service links are aggregated between servers and TOR switches, eth-trunk must be configured, and static LACP support is used to ensure the bundled links operate correctly and consistently. That requirement aligns with standard network design logic for service-plane access in container-based edge environments, where stability and predictable uplink behavior are essential. Because Lite Edge depends on reliable service-plane connectivity and TOR-based aggregation, the statement that service TOR switches need to support static LACP mode and require eth-trunk configuration is correct.

The correct answer is C because tripwire crossing detection is fundamentally based on analyzing the movement trajectory of an object relative to a predefined virtual line. In intelligent vision systems, the object is first detected, then tracked frame by frame, and its centroid positions are recorded to form a trajectory. The material explains that “A movement trajectory consists of positions of the centroid of a moving object in individual frames” and also states that “To accurately predict whether an object is likely to cross the tripwire, features need to be extracted from the object… Dynamic features: trajectory, speed, and direction. Tripwire crossing detection mainly involves the extraction of dynamic features of an object.”

This means the decisive event is whether the tracked path intersects the configured tripwire. Speed alone does not determine crossing, and simply being in motion is insufficient. Direction can be an additional filtering condition in some deployments, but the actual crossing judgment is established through trajectory analysis. Therefore, the system concludes that an object has crossed the tripwire when its motion trajectory intersects the tripwire line, making C the most accurate answer.
