NEW QUESTION # 31
A GPON access solution is suitable for areas with many centrally located sites, such as buildings and downtown areas.
Answer: A
Explanation:
Gigabit-capable Passive Optical Network (GPON) is an optical access technology that uses a point-to- multipoint architecture to connect multiple endpoints to a centralized optical network infrastructure.
Huawei's video-network curriculum identifies GPON as particularly suitable for areas with a large number of video sites deployed within relatively concentrated geographic locations, including buildings and urban areas.
In a GPON architecture, an Optical Line Terminal (OLT) connects to multiple Optical Network Units or Terminals (ONUs/ONTs) through an Optical Distribution Network (ODN). Passive optical splitters distribute optical connectivity without requiring electrically powered switching equipment at each splitter location.
This design reduces the amount of dedicated fiber required compared with point-to-point connections to every endpoint.
For video-surveillance deployments, GPON offers centralized access management, relatively low optical-fiber deployment costs, and substantial bandwidth capacity.
Huawei's course describes typical GPON transmission rates of approximately 2.488 Gbit/s downstream and
1.244 Gbit/s upstream for the GPON technology discussed in the V1.0 material.
The actual number of camera streams supported depends on the optical split ratio, video bit rates, network overhead, and available upstream capacity.
Because centralized, relatively dense surveillance deployments match the application scenario expressly described by Huawei, the statement is true.

NEW QUESTION # 32
Which statements correctly describe the relationship between a lens and depth of field (DoF)?
Choose two
Answer: A,B
Explanation:
Depth of field (DoF) refers to the distance between the nearest and farthest objects that appear acceptably sharp within a captured image. It is influenced by focal length, aperture, focusing distance, and the camera's imaging geometry.
Option A is correct. A long-focus lens provides a relatively narrow field of view and generally produces a shallower depth of field when other relevant conditions remain constant. This makes it suitable for applications requiring detailed observation of distant objects, although accurate focusing becomes particularly important.
Option B is incorrect. Long-focus lenses do not inherently provide a larger depth of field. Increasing focal length generally reduces the range that appears acceptably sharp when aperture and subject distance remain unchanged.
Option C is correct. A wide-angle lens has a shorter focal length and ordinarily provides a larger depth of field. It can maintain acceptable sharpness across a wider range of distances, which is useful for monitoring entrances, corridors, and large observation areas.
Option D is incorrect. Wide-angle lenses generally provide greater rather than smaller depth of field under comparable conditions.
Huawei's training material also demonstrates that reducing aperture size increases depth of field, while increasing aperture size decreases it. Therefore, lens selection and aperture configuration must be considered together.

NEW QUESTION # 33
Which of the following services does Huawei HoloSens IVS3800 provide?
Select All that Apply
Answer: A,B,C
Explanation:
Huawei HoloSens IVS3800 uses a layered, container-based software architecture that separates customer- facing business services from the basic infrastructure services required to operate the platform.
The three principal business-service categories identified in the official training material are image management, image analysis, and image search.
Option A is correct. Image analysis provides intelligent processing capabilities such as feature extraction, behavioral analysis, and video-content interpretation.
Option C is correct. Image search provides retrieval capabilities for structured data and feature information generated through intelligent analysis. It enables users to locate relevant objects and records efficiently.
Option D is correct. Image management handles video and image access, storage, forwarding, and related management operations.
Option B requires a distinction. Container management is indeed provided by IVS3800, but Huawei classifies it as a basic service rather than one of the three principal business-service modules. It manages service installation, deployment, lifecycle operations, and associated network and storage functions.
The examination's three-answer requirement therefore indicates that it is testing the business-service layer.
Huawei's logical architecture diagram explicitly separates image management, image analysis, and image search from the underlying container management service.

NEW QUESTION # 34
If an organization needs to carry out secondary development for a camera-for example, to develop client software that connects to the camera-which of the following protocols can be used for development?
Answer: C
Explanation:
Huawei's proprietary SDK protocol, identified as HWSDK in this question, is the intended solution for secondary development when an organization needs to develop customized software that directly accesses and controls camera functions.
Option B is correct because Huawei's SDK provides vendor-defined interfaces that developers can use to build applications interacting with supported devices. This includes scenarios such as customized client software, device integration, and access to supported camera capabilities.
Option A is incorrect in this context. TCP/IP provides network communication rather than the vendor-specific application interfaces needed for the development scenario described.
Option C, ONVIF, is an open interoperability standard used to integrate compatible network-video devices and platforms. Although ONVIF interfaces can also be implemented by developers, Huawei's training material distinguishes standardized interoperability from vendor-specific SDK-based secondary development.
Option D, GB/T 28181, is a video-surveillance networking and interoperability standard. Its primary role in the course is platform and device interconnection rather than the particular proprietary client-development approach described.
Huawei's slide on proprietary protocols specifically explains that SDK interfaces allow partners to develop software, including client applications, to access vendor devices.
Therefore, HWSDK is the precise answer intended by the training material.
"Vendors can provide SDK for their partners to call their devices for development." Official Huawei references:

NEW QUESTION # 35
Which of the following components are included in the anti-DDoS solution?
Select All that Apply
Answer: B,C,D
Explanation:
Huawei's Anti-DDoS architecture separates attack monitoring, malicious-traffic mitigation, and centralized policy administration into distinct functional components.
Option A - Detection center: Monitors traffic and identifies suspicious patterns indicating a possible DDoS attack. Detection mechanisms can evaluate abnormal traffic volumes, protocol behavior, and other indicators associated with malicious requests.
Option B - Cleaning center: Performs traffic mitigation by removing or suppressing malicious packets while allowing legitimate service traffic to continue. The purpose is to maintain the availability of protected video- security applications during an attack.
Option C - Management center: Coordinates security policies and mitigation actions. It receives information from the detection function and manages the response according to configured rules.
Option D - Router: Although routers participate in forwarding, redirecting, and transporting traffic, a router is not one of the three dedicated functional centers identified by the question. It serves as supporting network infrastructure rather than the specified Anti-DDoS management, detection, or cleaning component.
Huawei's course illustrates how detection results are communicated to the management system so that attack traffic can be cleaned according to appropriate mitigation policies.
The separation of these functions enables centralized operational control while distributing traffic-monitoring and mitigation responsibilities throughout the network architecture.
