22. Frage
Which of the following devices are part of a video security center?
Select All that Apply
Antwort: A,B,C,D
Begründung:
A video-security center is the centralized operational environment used to monitor, control, display, and coordinate video-surveillance services. Huawei's training material identifies the video wall, decoder, control keyboard, and matrix as components of the security-center architecture.
A). Video wall: Provides large-scale visual presentation of surveillance feeds, alarm-related images, and operational information. It supports simultaneous monitoring of multiple camera streams and coordinated incident management.
B). Decoder: Converts encoded digital video streams into image signals suitable for display. A decoder enables video received through a network to be presented on compatible monitoring screens.
C). Control keyboard: Allows operators to control surveillance functions, including video selection, switching, and supported pan-tilt-zoom operations. It provides a dedicated interface for monitoring-center personnel.
D). Matrix: Performs video switching and distribution, directing selected video sources to designated display outputs. This enables flexible presentation of surveillance information across multiple monitors.
These components operate together to provide a coordinated surveillance environment. The matrix manages video switching, the decoder prepares digital streams for display, the video wall presents surveillance images, and the control keyboard provides operational control.
Huawei's video-security center architecture explicitly includes all four devices, alongside the video-security client.

23. Frage
The digital video server (DVS) transforms analog signals into network signals for transmission.
Antwort: B
Begründung:
A Digital Video Server (DVS), also known as a digital video encoder, converts incoming analog video signals into encoded digital video streams suitable for transmission over an IP network.
The process begins when an analog camera generates video signals and delivers them to the DVS through an appropriate physical video interface. The DVS digitizes and encodes those signals using supported video- compression technology. The resulting digital streams can then be transmitted across a network to video- management platforms, client applications, recording devices, or decoding equipment.
This capability is important when integrating existing analog surveillance infrastructure into modern network- based video-security environments.
Huawei distinguishes the role of a DVS from that of a Digital Video Recorder (DVR). A DVR primarily combines video encoding with recording and local storage capabilities. A DVS concentrates on encoding and network transmission, enabling analog cameras to participate in an IP-based video-security solution.
For example, an organization with existing analog cameras can install a DVS instead of immediately replacing every camera. The encoded video can then be delivered through the network to an NVR or centralized surveillance platform.
The statement accurately describes this fundamental DVS function and is therefore true.
"DVSs focus on encoding and network transmission."

24. Frage
In which of the following complex environments can Huawei software-defined cameras (SDCs) operate properly?
Antwort: A,B,C
Begründung:
Huawei HoloSens software-defined cameras incorporate environmental protection, electromagnetic compatibility, and image-stabilization technologies to support deployments in challenging outdoor and industrial environments.
Option A is supported. Huawei explicitly describes anti-electromagnetic-interference design for camera deployments in railway and rail-transport environments. The training material identifies electromagnetic compatibility as an important reliability feature where electrical interference may be substantial.
Option C is supported. Huawei describes outdoor adaptation through environmental sealing, ingress protection, and self-cleaning viewing windows. The course specifically illustrates camera operation during rainy conditions and explains how water-repellent coatings improve visibility.
Option D is supported with a model-specific qualification. Huawei documents physical image-stabilization technologies designed to reduce image jitter caused by wind, structural movement, and vibration. Such technologies are relevant to railway-related vibration, although stabilization capability varies between camera models.
Option B requires qualification. Huawei documents image-defogging capabilities for fog, moisture, and dust, but this does not establish that every SDC can provide reliable observation through an arbitrary smoke environment. Performance depends on smoke density, wavelength, optics, and the installed camera.
Huawei's course emphasizes robust camera hardware and all-weather adaptability; however, these capabilities must be assessed against the environmental ratings and functional specifications of the particular model.

25. Frage
The Huawei HoloSens Intelligent Vision System (IVS) can connect to cameras from different vendors by using different access protocols for unified management. This enables users in upper-level areas to view live video or recordings from cameras in lower-level areas.
Antwort: B
Begründung:
Huawei HoloSens IVS supports unified video management across heterogeneous surveillance environments, including cameras supplied by different manufacturers and connected using different supported access protocols. The statement accurately describes an application scenario explicitly documented in the V1.0 training material.
The platform's camera-access function provides an abstraction layer between field equipment and centralized video-management applications. Compatible cameras can be integrated through supported interconnection mechanisms, permitting administrators to configure and manage devices through centralized services.
In a hierarchical surveillance deployment, lower-level platforms and cameras serve local monitoring requirements, while upper-level management domains provide broader operational supervision. Authorized users at the upper level can retrieve live-video streams and recorded footage originating from cameras deployed in subordinate areas.
This capability is particularly important for citywide surveillance, distributed enterprises, and multi-site security systems. It enables centralized observation without requiring every operator to access individual camera interfaces.
Huawei also describes management improvements through batch configuration and plug-and-play camera integration. These functions reduce repeated commissioning work and improve administration across large deployments.
Successful cross-level access depends on compatible protocols, platform interconnection, network reachability, and appropriate user permissions.
"Cameras from different vendors and using different access protocols are connected to the system for unified management." Official Huawei references:

26. Frage
Which statements about cloud storage are accurate?
Select All that Apply
Antwort: A,B,C
Begründung:
Cloud storage provides centrally managed storage resources that can be expanded, allocated, and adjusted according to application requirements. Huawei's video-security architecture uses cloud-based resource management to address the scalability and operational limitations of traditional isolated storage systems.
Option A is correct. Cloud storage supports flexible capacity expansion. Additional storage resources can be incorporated as surveillance data volumes increase, without necessarily redesigning the entire application architecture.
Option B is correct. Centralized storage management simplifies resource administration, monitoring, maintenance, and allocation. Administrators can manage shared storage resources more consistently than independently deployed recording systems.
Option C is correct. Cloud storage supports on-demand service provisioning. Storage capacity and service configurations can be adjusted according to changing application workloads, retention requirements, and deployment scale.
Option D is incorrect. High cost is not an inherent defining characteristic or advantage of cloud storage.
Actual costs depend on hardware architecture, consumption, data retention, replication, network usage, and operational requirements. Cloud architectures can improve resource utilization and reduce certain expansion and management costs.
Huawei's training material illustrates the transition from traditional storage to converged cloud storage, emphasizing resource pooling and on-demand block, file, and object storage services.
The central architectural benefits are scalability, centralized management, and flexible resource provisioning.
