H19-402_V1.0 exam torrent Huawei study guide

Huawei H19-402_V1.0 certification exam covers various topics, including data center network design, network topology, network security, network management, and network performance optimization. H19-402_V1.0 exam is divided into multiple sections, each covering a different aspect of data center network planning and design. To pass the exam, candidates must demonstrate a deep understanding of these topics and show their ability to apply this knowledge to real-world scenarios.

NO.31 Huawei 25KW half cabinet variable frequency air-cooled air conditioner, which of the following description is correct? (Multiple choice)

The capacity calculation of a single air conditioner with UPS is 1.21.732 full load current 3800.8/0.9

The capacity calculation of a single air conditioner with UPS is 1.251.732 full load current 380*0.8/0.9

The UPS capacity requirement for a single air conditioner is 15.8kVA. If UPS5000E is used, at least one 25kVA power module is required.

The UPS capacity requirement for a single air conditioner is 79.0kVA. If UPS5000E is used, at least two 40kVA power modules are required.

If a group of air conditioners is connected to a UPS system, then the capacity requirement of a single UPS system should be multiplied by the number of air conditioners running simultaneously. For example, if there is a 5+1 cold backup configuration, the capacity requirement of a single air conditioner UPS system should be

NO.32 Which of the following is not a characteristic of high-performance networks?

High throughput

Higher GPU computing power

Low latency

Zero packet loss

Comprehensive and Detailed 150 to 200 words of Explanation From Huawei data center:
Huawei data center materials describe a high-performance network using core technical indicators such as high throughput, low latency, and zero packet loss . These are the actual network characteristics used to evaluate whether a data center fabric can efficiently support AI computing, storage traffic, and east-west service communication. In Huawei’s intelligent lossless network design, the purpose is to build a fabric that forwards traffic at high speed, minimizes delay, and prevents packet loss under heavy load.
By contrast, Higher GPU computing power is not a direct network characteristic. It is an effect or business benefit that can result when the network performs well. Huawei explains that intelligent lossless networking improves AI cluster efficiency and helps computing resources operate more effectively, but GPU power itself belongs to the computing layer, not the network feature set. The network supports better GPU utilization; it does not define GPU computing power as one of its own characteristics.
Therefore, the correct answer is B .

NO.33 Which of the following air conditioning systems requires a cooling tower or dry cooler?

DX air-cooled type

CW air-cooled type

True

False

NO.36 Which of the following statements about FM800 operating conditions is correct?

Normal temperature 0 ℃ ~45C

Wide operating temperature range -40 ℃ ~55 ℃

True

False

NO.38 FusionModule800 operating temperature 20 ℃ ~45, FusionModule5000C~45 ℃

True

False

NO.39 Which of the following models has the widest input voltage range and is more adaptable to harsh power grids?

APC Galaxy7000

UPS5000-A

Emerson NXF

Eaton 9395

NO.40 What is the channel type of the typical configuration of FusionModule800?

Hot and cold aisles

Hot Aisle

NO.41 Tenants apply for data center network, storage, and compute resources. One department can be regarded as one tenant, so an enterprise has multiple tenants, and the enterprise ‘ s data center can be managed by one tenant administrator.

TRUE

FALSE

In Huawei CloudFabric and cloud platform architectures (such as those integrated with ManageOne and OpenStack ), the concept of a tenant is used to logically isolate resources such as network, compute, and storage . It is correct that one department can be treated as a tenant , and an enterprise can have multiple tenants representing different departments or business units.
However, the statement is false because it incorrectly claims that the entire enterprise data center can be managed by one tenant administrator . In Huawei’s design:
Each tenant has its own administrator , responsible only for that tenant’s resources.
A higher-level role, such as a cloud administrator or system administrator , manages the entire data center infrastructure across all tenants.
This separation ensures:
Multi-tenancy isolation
Security and access control
Clear responsibility boundaries
Huawei emphasizes role-based access control (RBAC) , where tenant admins cannot manage resources belonging to other tenants or the entire infrastructure.
Therefore, the correct answer is FALSE .

NO.42 Relevant standards stipulate that the AC cable voltage drop needs to be controlled within 3%. When designing a UPS system, it is recommended that the AC insulation voltage drop be controlled within ().

0.01

0.02

0.03

0.05

NO.43 UPS products such as PM and NXR need to be derated at 30 degrees, while UPS5000-E does not need to be derated below 40 degrees.

True

False

NO.44 NetCo18000-A013U13kW small cooling capacity temperature control product uses DC variable frequency compressor

True

False

NO.45 The asset management module of the NetEco management system can manage the equipment in the computer room: Which of the following equipment is not within the management scope of the NetEco asset management module?

Server

Storage Devices

Router

Office computer

NO.46 The outdoor unit model and temperature range that NetCol5000-A042H full cabinet row-level air- cooled variable frequency precision air conditioner can match are ()

NetCol500-A026 (-20~45°C)

NetCol500-A036 (-40~45°C requires low-temperature components)

NetCol500-A072 (-5~55°C)

NetCol500-A088 (-5~55°C)

NO.47 FusionModule500 provides free licenses for customers with 50 outlets. Is there a charge for more than 50 outlets?

True

False

NO.48 (Which of the following is not a capability of network overlay?)

NVEs can be deployed on physical switches.

Network overlay applies to private cloud users who have high requirements for the forwarding performance, O & M, and security.

Virtual and physical servers can access the network.

The controller delivers flow tables to NVEs synchronously.

In Huawei CloudFabric and VXLAN-based overlay networking, the overlay provides abstraction, flexibility, and scalability by decoupling logical services from the physical infrastructure. NVEs (Network Virtualization Edge nodes) can indeed be deployed on physical switches (such as leaf switches), which is a fundamental capability of hardware-based VXLAN fabrics. Additionally, overlay networks are designed to meet the needs of private cloud environments, offering high performance, simplified O & M, and enhanced security through network segmentation (e.g., VXLAN VNIs).
Overlay networks also support access for both virtual machines and physical servers, ensuring consistent connectivity regardless of workload type.
However, statement D is incorrect. In Huawei’s architecture, especially with BGP EVPN-based VXLAN, the control plane is distributed rather than relying on a controller to synchronously deliver flow tables. Devices dynamically learn and exchange forwarding information using EVPN. Even in SDN-based scenarios with iMaster NCE-Fabric, policy delivery is not strictly synchronous flow table pushing in the traditional sense (like OpenFlow).
Therefore, “controller delivers flow tables synchronously” is not a standard capability of Huawei overlay networks, making option D incorrect.

NO.49 The self-developed air conditioning control system has a visual group control network and supports up to 32 units

True

False
