H20-688_V1.0 Exam Dumps - Huawei HCSP Presales Questions and Answers

Exact Extract — Prevent Proliferation, and Reduce Losses, Develop Emergency Plans, and Conduct Regular Drills (PDF page 273, training slide 28)

Make the customer/EPC/construction party/fire department be familiar with the product emergency items, check the adequacy, suitability, and effectiveness of the emergency plan, and check whether the departments and individuals involved in the plan are clear about their responsibilities, familiar with the emergency plan procedures, and emergency response capabilities.

Technical Deep Dive:

Emergency drills are conducted to determine whether emergency response arrangements can effectively control incidents and protect personnel, facilities, and the surrounding environment.

The training identifies three principal characteristics for evaluation: adequacy, suitability, and effectiveness.

Option A is correct. Sufficiency corresponds to adequacy. The emergency plan must provide sufficient resources, procedures, personnel, equipment, and organizational arrangements to respond to foreseeable emergencies.

Option B is correct. Suitability evaluates whether the emergency procedures and resources are appropriate for the actual operational environment and potential incident scenarios.

Option D is correct in the intended terminology. Validity is being used to represent the effectiveness of the emergency plan—whether its procedures can produce the required response outcomes under relevant conditions.

Option C is incorrect. Necessity is not one of the three emergency-plan characteristics specifically identified for evaluation in the training.

For energy-storage installations, emergency drills may evaluate personnel evacuation, emergency notification, equipment shutdown, firefighting coordination, incident isolation, and management of potential thermal-runaway conditions.

SQA personnel should supervise the implementation of the drill, verify that participating stakeholders understand their responsibilities, and ensure that weaknesses are documented and corrected.

Terminology qualification: Huawei uses effectiveness, whereas the answer option uses validity. These terms are not universally interchangeable in formal management-system terminology, so D reflects the intended examination mapping rather than an exact wording match.

Final verification: A, B, D.

Exact Extract — Safety Operation Requirements 5/7: Prevention of Hoisting Accidents (PDF page 188, training slide 47)

Ensure that the angle between two cables is not larger than 90 degrees.

During hoisting, do not stand or walk under the crane or the hoisted objects.

Do not drag steel ropes and hoisting tools or bump the hoisted objects against hard objects during hoisting.

Install temporary warning signs or fences to isolate the hoisting area.

Technical Deep Dive:

Hoisting operations are classified as high-risk activities because lifting equipment failure, load instability, falling objects, and personnel exposure can lead to severe injuries or fatalities.

All four options are correct.

Option A protects both lifting equipment and transported loads. Dragging wire ropes across abrasive surfaces may damage individual strands, while collisions between suspended loads and solid structures can compromise load stability.

Option B addresses the angle between lifting cables. The training specifies a maximum included angle of 90 degrees. As the angle between sling legs increases, the tension in each sling also increases for a given load.

The approved lifting arrangement must account for sling angles, working load limits, load geometry, and the manufacturer ' s lifting specifications.

Option C requires temporary barriers or warning signs to prevent unauthorized personnel from entering the lifting area.

Option D prohibits personnel from standing or walking beneath the crane or suspended objects, reducing exposure to falling loads and lifting equipment failures.

Additional controls include verifying lifting personnel qualifications, inspecting ropes and hooks, checking load-bearing capacity, securing crane supports, and conducting a trial lift where required.

The lifting operation must follow an approved hoisting plan and applicable safety procedures.

Final verification: A, B, C, and D are explicitly supported.

Exact Extract — Service SQA Roles and Key Business Activities (PDF page 121, training slide 14)

1. Regularly collect customers ' requirements on safety and quality.

2. Organize efforts to analyze customer requirements, improve countering measures, and conduct closed-loop management.

3. Regularly summarize the closed-loop improvements on the voice of customers, and organize related domains to make dedicated improvements for common issues.

Technical Deep Dive:

The customer voice listener is one of the five key responsibilities in Huawei ' s Service SQA role model. This responsibility establishes a structured mechanism for capturing customer expectations and translating customer feedback into measurable improvements in service safety and quality.

The activities emphasize three operational functions.

Customer requirement collection: SQA personnel systematically collect customer expectations concerning delivery quality, equipment reliability, construction safety, maintenance processes, and service performance.

Analysis and closed-loop management: Collected requirements and complaints must be assessed, assigned to responsible stakeholders, and addressed through appropriate corrective or preventive measures. The process should maintain traceability between the original requirement, corrective action, verification, and closure.

Continuous improvement: Repeated or common customer concerns should be consolidated into improvement initiatives involving relevant business domains. These may include changes to delivery specifications, inspection procedures, training requirements, or quality control activities.

Options A, C, and D accurately describe these responsibilities.

Option B is incorrect because regularly arranging visits to high-level customers is not identified as a specific business activity of the customer voice listener role.

Executive customer visits may be appropriate within broader customer relationship management or project governance, but they are not equivalent to the defined SQA responsibility for collecting, analyzing, and closing safety and quality requirements.

The central objective is systematic customer feedback management, rather than customer engagement based on organizational seniority.

Final verification: B is the only incorrect statement.

Exact Extract — Safety Operation Requirement 2: PPE & Professional Tools (PDF page 12, training slide 11)

Electrical work

PPE: 1. Insulated gloves 2. Insulated shoes (anti-smashing)

Professional Tool: Wooden ladder and insulated tools.

Technical Deep Dive:

Electrical work presents risks including electric shock, electrical burns, short circuits, and arc-flash incidents.

Appropriate personal protective equipment and insulated tools are therefore essential components of Huawei ' s electrical safety requirements.

Option A is correct. Insulated footwear provides protection against specified electrical hazards when appropriately rated, maintained, and used according to applicable requirements.

Option C is correct. Insulated tools reduce the likelihood that conductive tool surfaces will create an accidental electrical connection or expose personnel to hazardous voltage.

Insulated screwdrivers, wrenches, and other approved equipment must be selected according to the applicable electrical safety requirements.

Option D is correct. Insulated gloves protect the hands against electrical contact hazards within their specified ratings and limitations.

Gloves must be inspected before use and replaced if damaged or otherwise unsuitable.

Option B is incorrect. An ordinary face mask does not provide electrical insulation and is not a substitute for electrical protective equipment.

Specialized arc-rated face shields and other protective equipment may be required for particular electrical hazards, but these are not equivalent to ordinary face masks.

The use of PPE does not eliminate the requirement to isolate hazardous energy sources before maintenance whenever required.

Final verification: A, C, D.

Exact Extract — Safety Operation Requirements 1/7: Electric Shock Protection (PDF page 184, training slide 43)

Do not work with power on during installation. Do not install or remove a cable with power on. Transient contact between the core of the cable and a conductor will generate electric arcs or sparks, which may cause a fire or personal injury.

Technical Deep Dive:

Inverters with multiple electrical inputs may receive energy from several independent sources. Isolating only the specific circuit being serviced does not necessarily eliminate all hazardous voltages within the equipment.

Huawei inverters may have multiple photovoltaic DC inputs, DC switches, grid-connected AC circuits, energy-storage interfaces, or other product-specific electrical connections.

The fundamental safety principle is complete isolation of all relevant energy sources before maintenance, following the shutdown sequence specified for the particular model.

A safe isolation procedure generally requires identifying the connected sources, executing the approved shutdown procedure, isolating the applicable AC and DC circuits, preventing unintended reconnection, observing the manufacturer ' s capacitor-discharge waiting period, and verifying the absence of hazardous voltage using suitable test equipment.

The exact order of isolation is product-dependent. It must not be improvised.

Residual electrical energy may remain in internal capacitors after external switches are opened. Consequently, an inverter can present an electric shock hazard even after it appears to have been shut down.

Huawei ' s SUN2000 maintenance instructions provide a practical example: the maintenance procedure includes disconnecting the AC supply, isolating all relevant DC inputs, checking electrical conditions, and observing the specified waiting period.

The statement is false because switching off a single input or output does not guarantee that the inverter is safely de-energized.

Final verification: B is supported by the electrical isolation principles and Huawei ' s product maintenance requirements.

Exact Extract — Adaptation to SQA Operation Standard Process (PDF page 252, training slide 7)

Obtain project information. Obtain project information and identify quality risks.

Develop quality plans. Analyze the key items of the project and develop the quality management plan.

Check qualifications. Check whether the certification of the delivery partner company and the special operation qualification certificates of the installation personnel are within the validity period.

Conduct technical and safety disclosure. Participate in technical and safety disclosure, and supervise the supervision engineer to complete technical and safety disclosure to construction personnel, project team leader, customer/EPC and other related personnel before construction entry.

Technical Deep Dive:

The construction preparation phase establishes the operational, technical, and quality assurance conditions necessary for controlled project execution.

Option A is correct because all four activities belong to the preparation stage in Huawei ' s SQA operation standard process.

Preparing for entry involves obtaining project information, understanding the delivery scope, identifying site conditions, and examining potential quality and safety risks.

Quality planning establishes project-specific objectives, critical control points, inspection requirements, and responsibilities. The SQA coordinates relevant business departments to identify risks and implement preventive measures.

Qualification verification ensures that service partners, installation engineers, and personnel conducting specialized operations possess the required valid certifications.

Technical and safety disclosure ensures that construction personnel and project stakeholders understand equipment installation requirements, operating procedures, safety precautions, and preventive measures before construction begins.

The supervision engineer is responsible for conducting the required disclosure, while the SQA supervises its completion and checks the corresponding documentation.

These activities reduce the probability of construction defects, unauthorized work, safety incidents, and subsequent project delays.

The preparation phase is therefore not limited to administrative arrangements. It establishes the controls required for quality assurance throughout subsequent construction activities.

Final verification: A.

Exact Extract — Acceptance Upon Completion (PDF page 229, training slide 25)

The customer confirms the completion of the project and signs the completion acceptance report in written form.

In principle, the signing of the service completion report is the node for internal and external ETM completion.

Technical Deep Dive:

Formal project acceptance is an essential control activity in Huawei Digital Power service delivery.

Option B is correct because an oral notification cannot replace the required written completion-acceptance confirmation.

The completion-acceptance report provides objective evidence that the customer has reviewed and acknowledged the relevant project deliverables.

Depending on the project, these deliverables may include equipment installation records, commissioning results, quality inspection reports, defect rectification records, and relevant equipment handover documentation.

A properly executed acceptance process establishes the status of the delivered services and helps identify any outstanding contractual or technical obligations.

Written confirmation also improves traceability and reduces the risk of disputes concerning the completion date, acceptance criteria, outstanding defects, or the agreed scope.

The training material specifically requires the customer to confirm project completion and sign the acceptance report in writing.

Where an approved digital acceptance system is available, the applicable electronic authorization and record-retention procedures may also be used.

However, verbal communication alone does not satisfy the prescribed formal acceptance requirement.

Final verification: B.

Exact Extract — Onsite Storage Requirements (PDF page 176, training slide 35)

On-site management: Take moisture-proof measures on the ground; keep the goods away from direct sunlight and heat sources; keep dry and ventilated; do not perform hot work operations such as welding or cutting

Technical Deep Dive:

Energy-storage products, particularly lithium-ion batteries, require controlled warehousing conditions because mechanical damage, elevated temperatures, electrical faults, and ignition sources can create significant fire and thermal-runaway hazards.

Option C is correct. Welding is classified as hot work because it generates intense heat, sparks, molten metal, and other potential ignition sources.

Performing welding activities in storage areas containing energy-storage batteries can expose stored products, packaging materials, and surrounding infrastructure to unacceptable thermal and fire risks.

Huawei ' s warehousing requirements prohibit hot work operations such as welding and cutting in these storage areas.

Other activities listed in the question may be permitted under appropriate operating conditions.

Stacking must comply with the specified height limitations, packaging requirements, load-bearing capacity, and storage arrangement.

Moving requires suitable mechanical handling equipment, trained personnel, and precautions against impact, puncture, dropping, or deformation.

Transporting must comply with applicable dangerous-goods classification, packaging, handling, and transport requirements.

Battery storage areas should also maintain suitable ventilation, environmental monitoring, firefighting facilities, and separation from incompatible materials.

An SQA engineer must verify that the warehouse operator follows the applicable storage requirements and that prohibited activities are prevented through clear site controls.

Final verification: C is explicitly prohibited by the onsite storage requirements.

Exact Extract — Service Preparation (PDF page 224, training slide 20)

Proactively contact the customers by email or phone, obtain the onsite construction time, and learn about the requirements of the construction plan, key materials, and tools (such as installation tools and test tools).

Technical Deep Dive:

The project kick-off coordination meeting establishes the operational baseline for project delivery. Its primary purpose is to ensure that Huawei, its service partners, and the customer have a consistent understanding of project scope, execution arrangements, responsibilities, and delivery milestones.

Option A is supported. The project construction scope and solution establish what equipment, activities, and services are included in the project. Confirming this information prevents scope disagreements, omissions, and inconsistencies between engineering design and onsite implementation.

Option C is supported. Construction duration and planned milestones directly influence resource allocation, equipment delivery, installation scheduling, inspection activities, and commissioning arrangements.

Option D is operationally appropriate. A project contact directory supports communication, issue escalation, coordination, and accountability. It should identify the relevant personnel and organizational responsibilities on both sides.

Option B is ambiguous. Customer preferences can influence delivery requirements, but the term is insufficiently specific. A customer preference affecting the installation schedule, operating conditions, or agreed scope may legitimately require confirmation. However, general preferences are not identified as a separate mandatory kick-off item in the available training passage.

Effective project coordination also requires clear communication channels, responsibilities for corrective actions, and agreement on important project dependencies.

Exact Extract — Technical and Safety Disclosure (PDF page 260, training slide 15)

Technical and safety disclosure is a key measure to prevent accidents. Effective technical and safety disclosure ensures that construction personnel are familiar with device installation requirements, operation processes, and safety regulations. This reduces accidents, improves work efficiency, and ensures device installation quality and delivery reliability.

Additional Extract — Adaptation to SQA Operation Standard Process (PDF page 252, training slide 7): Participate in technical and safety disclosure, and supervise the supervision engineer to complete technical and safety disclosure to construction personnel, project team leader, customer/EPC and other related personnel before construction entry.

Technical Deep Dive:

Technical and safety disclosure is a mandatory preparation activity within Huawei ' s project delivery quality assurance framework.

Its purpose is to establish a common understanding of technical procedures, construction standards, operational risks, and safety responsibilities before construction begins.

Option A is correct. Customer and EPC representatives require relevant information about construction arrangements, safety conditions, interfaces, and project responsibilities.

Option B is correct. Construction personnel must understand site-specific hazards, approved construction methods, protective measures, and installation limitations.

Option C is correct. Installation engineers require detailed technical information about equipment installation procedures, electrical connections, operational precautions, and acceptance requirements.

Option D is correct. The PD, or Project Director, must understand the relevant technical and safety requirements because the role coordinates project activities and has overall project quality responsibilities.

The disclosure should cover personnel qualifications, technical requirements, safety precautions, identified risks, and corresponding preventive measures.

Huawei ' s process also requires a Technical and Safety Disclosure Report. Appropriate participants must sign the report after the disclosure to establish traceable confirmation.

The SQA supervises the process and checks that the required stakeholders have received and acknowledged the information.

Question wording note: The training uses both construction personnel and installation personnel, which may overlap in practice. All four options are supported by the broader disclosure process. The timing requirement is before construction entry, not necessarily before every participant physically arrives at the project location.

Final verification: A, B, C, and D.
