Free Practice Questions for Huawei H12-521_V1.0 Exam

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.

CPU → Central processing unit

GPU → Graphics processing unit

FPGA → Field-programmable gate array

NPU → Neural processing unit

The correct matching is based on the standard definitions of the four processor types used in intelligent vision architecture. A CPU is the central processing unit , which handles general-purpose control, logic execution, and system coordination. A GPU is the graphics processing unit , originally designed for graphics rendering but now widely used for parallel computing tasks. An FPGA is a field-programmable gate array , which can be reconfigured for specific hardware logic functions and is valuable in acceleration and low-latency processing scenarios. An NPU is a neural processing unit , specialized for AI inference and deep-learning operations.

In intelligent vision systems, these processors serve different but complementary roles. The CPU manages operating control and service orchestration. The GPU accelerates highly parallel workloads. The FPGA supports custom hardware logic and fast pipeline processing. The NPU is especially important for AI-based vision services because it is optimized for neural-network computation, target recognition, and inference efficiency. This processor division is fundamental in intelligent camera, edge, and cloud architecture, where workload specialization improves overall system performance and intelligence capability.

The correct answer is A. trustlist . In checkpoint and vehicle control logic, the system compares recognized license plates against configured vehicle lists and then determines whether an alarm or release action is required. The material explains that in a micro checkpoint scenario the system can “generate alarms after matching passing vehicles with vehicles in the list” . This means the behavior depends on how the vehicle list is defined.

From a professional intelligent-transportation and security-management perspective, a trustlist is the list used for vehicles that are allowed to pass normally without being treated as suspicious targets. By contrast, a blocklist or redlist is associated with vehicles that should trigger attention, control, interception, or alarm. A temporary list may be used for short-term management, but it does not inherently mean “pass without alarm.” Therefore, if the intention is to let known authorized vehicles pass through the checkpoint without alarm generation, they should be added to the trustlist . That is the standard whitelist-style logic used in vehicle management systems.

The Cloud Service Platform (CSP) is the underlying infrastructure that manages containers, resources, and services for the intelligent vision platform. Routine maintenance and health checks are essential to ensure the continuous availability of video surveillance services. A comprehensive routine check of the CSP encompasses multiple layers of the system architecture.

First, the License status must be verified to ensure that all intelligent functions and channel capacities remain authorized and active. Second, monitoring CPU and memory usage is critical to identify potential resource bottlenecks that could lead to service instability or video stuttering. Third, for systems deployed in high-availability environments, the Cluster running status (including two-node cluster heartbeat and synchronization) must be checked to ensure failover capabilities are intact. Finally, since the platform utilizes a microservice architecture, checking the CSP and container running status is mandatory to verify that all functional modules (like the VCNAPI or BMU) are active and isolated as intended. By performing these checks regularly, administrators can proactively address issues before they trigger critical system alarms or data loss.

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.

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 B. FALSE . The statement is internally inconsistent because it says there are nine parts , but then lists more than nine items . More importantly, the construction sequence in the training material is described differently. The document states that civil engineering implementation includes “onsite measurement and routing, site arrangement, foundation pit excavation, lightning protection and grounding, foundation pit bedding, reinforced cage making, foundation template making, concrete casting, concrete maintenance, foundation pit backfilling, handhole making (optional), and trenching and cabling (optional)”

That official sequence does not match the wording in the question exactly. Terms such as construction material entry , ground part connecting , template removal , and muck backfilling are either not stated in the same form or are not presented as part of a fixed nine-step list. From a professional project-delivery viewpoint, foundation construction is indeed a staged civil process, but the exam statement is inaccurate because both the count and the listed procedure names do not align with the material. Therefore, the statement should be judged false.

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.
