質問 # 21
Which of the following best describes the video synopsis function?
- A. It only performs manual frame-by-frame search of recorded video.
- B. It converts all video into still images for faster storage.
- C. It enlarges a target in live video for clearer playback.
- D. It fuses target trajectories and background images to generate a compact video.
正解：D
解説：
The correct answer is B because video synopsis is designed to compress long-duration video into a shorter, information-dense presentation by extracting moving objects and reorganizing their activity over time. The material explains the workflow clearly: "Moving object detection involves algorithms such as background modeling, scene segmentation, and moving object extraction" , then "Object trajectory extraction involves object tracking algorithms such as TLD and KCF" , and finally "Generate a compact video.
That is, fuse the target trajectory set and background image into frames, and combine frames into video" This directly matches option B .
The same section also demonstrates the practical benefit by stating that "The video synopsis feature compresses the original 24-hour-long video into a 3.5-hour video" From an intelligent vision operations perspective, this greatly improves investigation efficiency because users can review suspicious activity faster without watching the full original recording. Option A describes local zoom behavior, not synopsis. Option C is incorrect because synopsis does not turn video into still images.
Option D is the opposite of synopsis, since synopsis reduces manual review effort rather than depending on it.
質問 # 22
Which of the following issues need to be focused on during solar PV module check?
- A. Check whether the solar PV module support is corroded or rusty.
- B. Check whether the solar PV module support is stable.
- C. Check whether there are covers such as oil stains, dust, or snow on the surface of the solar PV module.
- D. Check whether the solar PV module is damaged.
正解：A、B、C、D
解説：
The correct answers are A, B, C, and D because a proper solar PV module check must cover both the module condition and the mechanical support condition . A damaged panel can reduce charging efficiency or create safety risks. Dirt, oil stains, dust, or snow on the panel surface can block sunlight and reduce power- generation performance. At the same time, the support structure must be checked for corrosion, rust, and stability , because outdoor PV assemblies are continuously exposed to weather, vibration, and environmental aging.
This conclusion is also consistent with the overall site-power design described in the training material, where Huawei's integrated site solution includes "PV modules: two PV modules" and uses "SolarMax, and GridMax technologies to maximize energy efficiency of solar energy and mains and provide secure and reliable power supply" . Since PV modules are part of the site power system, both energy-conversion efficiency and structural reliability must be maintained. In actual maintenance practice, a clean, intact, and firmly supported PV module is necessary for stable long-term operation. Therefore, all four listed checks are valid and should be included.
質問 # 23
The function of the lens is similar to that of the human eye. In order to adapt to changes in environmental illuminance, the human eye uses an automatically adjustable iris to control the intensity of light reaching the retina to improve the image quality: while the camera lens uses adjustment () to adjust the arrival of the sensor Light intensity.
- A. Aperture
- B. Light transmittance
- C. Field of view
- D. Focal length
正解：A
質問 # 24
The implementation process of video summarization technology is mainly divided into the following stages: video segmentation, target detection, background extraction, background deletion, and summary completion.
- A. True
- B. False
正解：A
質問 # 25
Huawei integrated video site solution provides power supply, energy storage, and PV modules for video sites, and applies to multiple power supply scenarios such as mains-only, solar-only, and solar-grid hybrid power supply scenarios.
- A. TRUE
- B. FALSE
正解：A
解説：
The correct answer is A. TRUE . Huawei's integrated video site solution is designed as a complete outdoor site power platform rather than just a simple distribution unit. The material shows this clearly through the PowerCube architecture, where the system supports "high-performance lithium batteries" and includes
"PV modules: two PV modules" , while also using "SolarMax, and GridMax technologies to maximize energy efficiency of solar energy and mains and provide secure and reliable power supply" . These statements directly confirm the three core elements referenced in the question: power supply , energy storage
, and PV modules .
From a solution-design perspective, this means the platform is intended for flexible deployment in different field conditions. If stable commercial power is present, it can operate in a mains-dominant scenario. If the site is remote, solar generation with battery storage becomes feasible. Where reliability and sustainability must be balanced, hybrid grid-and-solar deployment is appropriate, and the material even notes that "The grid hybrid scenario is used as an example" during installation guidance . Therefore, the statement is fully consistent with the integrated site solution concept.
質問 # 26
Which of the following documents need to be prepared by engineers before IVS LLD?
- A. LLD report
- B. JSON file
- C. Project configuration file
- D. Network plan file, including the network segment and IP address range on the live network.
正解：B、C、D
解説：
The correct answers are A, C, and D because the documents prepared before IVS low-level design are the input materials used for design, deployment generation, and parameter definition, while the LLD report is an output of the LLD activity itself. The material emphasizes that network planning must be completed in advance, and the deployment process requires predefined addressing and parameter information. This is consistent with statements such as determining the network segment and IP address range for each network plane before deployment, and with the repeated use of fixed external service and management IP planning in domain and cluster configuration workflows .
From an engineering workflow perspective, the network plan file is required because network segments, IP ranges, and live-network planning must be decided in advance. A project configuration file is also needed because it carries deployment-specific parameters for the project. A JSON file is typically used as a structured import or export artifact generated by design tools and then consumed during planning or deployment preparation. However, the LLD report is not a prerequisite input document; it is the design deliverable produced after engineers complete the LLD work. Therefore, the required pre-LLD preparation documents are A, C, and D .

質問 # 37
Which of the following is not an ONVIF standard?
- A. Profile A
- B. Profile T
- C. Profile B
- D. Profile S
正解：C
解説：
The Open Network Video Interface Forum (ONVIF) provides a standardized framework for the interoperability of IP-based physical security products. These standards are organized into specific "Profiles" that define the features supported by devices and clients. Standard interfaces such as ONVIF are used to connect cameras to the IVS platform, facilitating a future-proof ecosystem where hardware from different vendors can communicate seamlessly.
Among the recognized standards, Profile S is the most common, used for basic video streaming and configuration. Profile T is a more modern standard designed for advanced video streaming, specifically supporting H.265 encoding and metadata reporting. Profile A is utilized for broader access control configurations, allowing for the integration of security management systems. Other profiles include Profile G for edge storage and Profile Q for quick installation. However, Profile B is not a recognized ONVIF standard profile. Adhering to these standardized formats ensures that recording streams can be accessed through external interfaces and that the system provides a channel for reporting metadata (structured data) for exchange with the platform, regardless of the underlying hardware differences.
