質問 # 49
Video at 30 fps is smoother than video at 60 fps.
正解：B
解説：
The statement is false because, under comparable capture and playback conditions, video recorded at 60 frames per second (fps) generally provides smoother motion representation than video recorded at 30 fps.
Frame rate specifies the number of individual images captured or displayed during one second.
At 30 fps, a new image is presented approximately every 33.3 milliseconds. At 60 fps, a new image is presented approximately every 16.7 milliseconds.
The higher frame rate provides more frequent updates of moving objects, reducing the apparent interval between successive motion positions.
This is particularly useful in video-security applications involving rapidly moving vehicles, crowded environments, and other scenes where motion continuity is important.
Huawei's training material explicitly states that higher frame rates produce smoother images, while lower frame rates increase visible motion jitter.
However, increasing frame rate also creates additional requirements for video encoding, network bandwidth, storage capacity, and processing performance.
The practical benefit depends on the complete video pipeline, including camera capability, recording configuration, display refresh rate, and available bandwidth.
A 60 fps stream cannot deliver its intended motion advantage if frames are excessively dropped or the playback system cannot display them appropriately.
Nevertheless, when comparing equivalent video streams under suitable operating conditions, 60 fps provides smoother motion than 30 fps.

質問 # 50
Which of the following storage methods are commonly used in a video security system?
Select All that Apply
正解：A、B、C、D
解説：
Video-security systems use several storage architectures and recording devices to meet different requirements for recording capacity, reliability, scalability, and centralized management. All four listed technologies can be used to store surveillance video.
A). Disk array: Disk arrays combine multiple physical storage drives into a logical storage resource.
Depending on the implementation, RAID technology can improve storage availability, provide redundancy, and support the continuous writing of surveillance recordings.
B). Digital video recorder (DVR): A DVR primarily receives video from analog cameras, converts the incoming signals into digital recordings, and stores the resulting video data on local storage devices.
C). Cloud storage: Cloud storage provides scalable storage resources through a centrally managed infrastructure. It is especially relevant to large surveillance deployments requiring flexible capacity expansion and centralized storage management.
D). Network video recorder (NVR): An NVR receives encoded digital video streams from IP cameras across a network and manages their storage, retrieval, and playback.
These solutions differ in architecture and operating characteristics. DVRs and NVRs are recording systems, disk arrays are storage infrastructure, and cloud storage is a resource-delivery architecture.
Huawei's training material discusses these technologies within the broader evolution from analog video systems to network-based and cloud-oriented surveillance platforms.

質問 # 51
Which Huawei HoloSens Intelligent Vision System (IVS) service feature can store valid, valuable video clips for later video analysis?
正解：B
解説：
The image information library is the Huawei IVS feature responsible for unified management and retention of valuable video, image, and structured information that may be needed for subsequent analysis.
Option B is correct because Huawei explicitly associates the image information library with storing useful video information for later analysis and managing the lifecycle of retained data.
The architecture includes three information-management categories: real-time video management, semi- structured image-data management, and structured metadata management.
The system can retain relevant surveillance content and manage stored data through its lifecycle. This includes cleaning and recycling unnecessary information to prevent the inefficient consumption of storage resources.
Option A - 1 + N (AI proxy): This capability primarily enables intelligent cameras or analysis resources to extend intelligent-processing functionality to other video sources. It does not identify the specific information- library service described in the question.
Option C - Cloud-edge synergy: This supports collaboration between upper-level and lower-level systems, including task distribution, resource coordination, and algorithm management.
Option D - Video forwarding: This distributes video streams to clients or other platform components rather than providing the particular retained-information management service.
The official image-information library slide explicitly establishes the intended answer.

質問 # 52
Which of the following statements are accurate about the video security gateway?
Select All that Apply
正解：A、B、C
解説：
Huawei's video security gateway provides identity authentication and access control to protect camera connections and video-service traffic. The official training material directly establishes options B, C, and D.
Option B is correct. The gateway identifies unauthorized device connections and data-access attempts, blocks prohibited activity, and generates security alarms. Access decisions can consider information such as source and destination IP addresses, ports, and communication protocols.
Option C is correct. The gateway permits authorized video-service traffic and restricts connections that do not satisfy established security policies.
Option D is correct. The gateway authenticates camera identities using device information such as IP address, MAC address, and serial number, improving the security of camera access to the surveillance network.
Option A is not established as a gateway function. Huawei assigns prevention of DDoS attacks and network congestion to a separate traffic-cleaning device. The gateway may incorporate intrusion-prevention capabilities, but that does not establish that it provides the dedicated DDoS-cleaning function described in option A.
The distinction between access authentication and volumetric attack mitigation is important when designing video-network security architecture.

質問 # 53
Compared with optical image stabilization, electronic image stabilization provides better results and costs less.
正解：B
解説：
The statement is false because electronic image stabilization (EIS) generally costs less than optical image stabilization (OIS), but Huawei's training material identifies optical stabilization as providing better stabilization results.
Optical image stabilization compensates for camera movement through an optical stabilization mechanism.
Depending on camera design, this mechanism adjusts optical components to reduce the displacement of the image caused by vibration or shaking.
Because optical correction occurs before image capture, it can preserve more image detail and avoid certain limitations associated with post-processing.
Electronic image stabilization, by contrast, uses image-processing algorithms to estimate and compensate for movement. EIS can digitally reposition, crop, or transform video frames to reduce apparent shaking.
Electronic stabilization can be implemented with fewer dedicated mechanical components, which generally reduces hardware cost and design complexity. However, digital correction may introduce cropping, interpolation artifacts, or reduced effective image resolution.
These characteristics are particularly important for cameras installed on poles, towers, roadside infrastructure, or locations exposed to mechanical vibration.
The question combines two claims: better stabilization and lower cost. Although the lower-cost characteristic is generally accurate for EIS, the claim that it produces better results contradicts the Huawei course material.
Therefore, the complete statement is false.
"The optical image stabilization has better effect and higher cost than the electronic image stabilization." Official Huawei references:
