H20-688_V1.0 HCSP-Field-SQA V1.0 Questions and Answers

Exact Extract — ISO 9000 Definition of Quality (PDF page 113, training slide 6)

ISO 9000 defines quality as the " degree to which a set of inherent characteristics fulfills requirements " .

– Inherent characteristics (such as appearance, shape, performance, maintainability and reliability), which is opposite to assigned characteristics (such as price, name and code).

– Quality is conformance to requirements.

– Requirements include demands and expectations of customers and other related parties.

Technical Deep Dive:

Quality is a multidimensional concept encompassing the characteristics that determine whether a product or service satisfies specified requirements and stakeholder expectations.

For Huawei Digital Power products, quality extends beyond basic functional performance to include operational safety, dependable service, and effective maintenance throughout the product lifecycle.

Option A — Safety: Safety is a fundamental quality characteristic because equipment must operate without exposing personnel, property, or the environment to unacceptable risks. Examples include electrical insulation, overtemperature protection, protective grounding, and battery safety controls.

Option B — Reliability: Reliability describes the ability of equipment to perform its required functions under specified conditions for a defined period. It is particularly important for UPS systems, energy-storage installations, and power conversion equipment.

Reliability may be evaluated through failure rates, availability, mean time between failures (MTBF), and other performance indicators.

Option C — Serviceability: Serviceability addresses how effectively equipment can be inspected, diagnosed, repaired, and restored to operational condition. It includes fault visibility, maintenance accessibility, service procedures, replacement efficiency, and technical support capabilities.

Effective serviceability reduces service restoration time and total lifecycle maintenance costs.

These characteristics are interconnected. Equipment that is reliable but difficult to maintain may still impose considerable operational risk. Similarly, products must provide required performance without compromising safety.

Final verification: D is correct because safety, reliability, and serviceability are all recognized product quality attributes.

Exact Extract — Entry Management: Equipment and Materials Acceptance (PDF page 267, training slide 22)

The package is not intact. Communicate with the EPC/customer and owner about whether to further check and receive goods.

Damaged equipment: Remind the supervision engineer and project team to communicate with the supply department and fill in the Cargo Replacement Application Form.

Technical Deep Dive:

Huawei ' s entry-management process distinguishes between damage to the outer packaging and confirmed damage to the equipment itself. These conditions require different responses.

Option D is correct because the question specifically states that the outer package is damaged.

When packaging damage is identified during goods receipt, the responsible personnel must coordinate with the EPC, customer, and owner to determine whether further inspection and acceptance are appropriate.

The condition of the packaging must be documented, and the equipment must be evaluated before installation or commissioning is authorized.

Option A is incorrect. The SQA and supervision engineer cannot independently authorize receipt solely on the basis of their own assessment when the prescribed process requires consultation with the relevant project stakeholders.

Option B is incorrect for the stated condition. The Cargo Replacement Application Form is associated with confirmed equipment damage. Damaged packaging alone does not automatically establish that replacement is necessary.

Option C is incorrect as the direct response. Evaluation of whether equipment can be installed or must be returned for repair or replacement applies when the equipment has been damaged during transportation or handling.

If inspection confirms equipment damage, the corresponding escalation and replacement procedure must be followed. Damaged equipment must not be installed or connected to the network without appropriate authorization and technical confirmation.

Important answer-key correction: B is not the appropriate answer for damaged outer packaging alone. The Huawei process explicitly maps package not intact to communication with the EPC/customer and owner.

Final verification: D.

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 — Environment Management: The SQA Supervises the Completion of Environment Survey (PDF page 265, training slide 20)

Before the equipment enters the site, the SQA checks the environment survey report provided by the supervision engineer and initiates handling according to different results.

1. Environment requirements are met: The SQA notifies Huawei of delivery.

2. Environment requirements are not met: The SQA notifies the supervision engineer to track the rectification. If the rectification requirements are met, the SQA notifies Huawei of delivery. If the rectification is not performed or the requirements are not met, organize the owner, Huawei, and EPC to handle the problem. After an agreement is reached through discussion, notify Huawei of delivery.

Technical Deep Dive:

Environment verification is an important quality control activity before Huawei Digital Power equipment is delivered to or installed at a project site.

Option C is correct because the supervision engineer is the designated person to follow up on rectification when an environmental nonconformity is identified.

The SQA reviews the environment survey report and determines whether the storage and installation conditions satisfy the applicable product specifications.

These checks may include environmental temperature, humidity, ventilation, installation clearance, foundation conditions, electrical safety, and protection against water or dust ingress.

When the requirements are not met, the SQA notifies the supervision engineer to coordinate and monitor corrective actions.

The supervision engineer must follow the rectification process and confirm whether the deficiencies have been corrected.

If the environment subsequently meets the requirements, the SQA can notify Huawei to proceed with delivery.

If rectification is incomplete or unsuccessful, the issue must be escalated for coordination among the owner, Huawei, and EPC.

This process establishes a clear relationship between quality oversight, corrective-action implementation, and project escalation.

Final verification: C.

Exact Extract — Four Safety Management Phases (PDF page 155, training slide 14)

Proactively correct others ' violations, and show care for others ' safety, team honor, and safety beyond work.

Technical Deep Dive:

Team management represents the most mature phase in Huawei ' s four-stage safety-management model.

At this stage, employees demonstrate collective ownership of safety performance rather than depending exclusively on management supervision or focusing only on personal compliance.

Option C is correct because the statement describes the distinctive characteristics of team-oriented safety management.

Employees proactively identify unsafe behavior, intervene when colleagues violate safety requirements, and support one another in maintaining safe working conditions.

For example, when a technician begins electrical maintenance without the required protective equipment, another team member should intervene and ensure that the appropriate safety precautions are implemented before work continues.

Similarly, construction personnel should report unsafe lifting practices, incorrect electrical isolation, inadequate site barriers, and other hazards even when those activities fall outside their immediate responsibilities.

Team management extends beyond compliance monitoring. It establishes a workplace culture in which employees collectively prevent accidents and continuously improve safety practices.

The distinction from self-management is particularly important. Self-management focuses on individual safety awareness and disciplined personal behavior, whereas team management involves active concern for coworkers and collective safety outcomes.

Supervision and management, by contrast, relies more heavily on formal inspection, monitoring, and enforcement.

Final verification: C corresponds directly to the team management phase.

Exact Extract — A Fire Accident in an Energy Storage Plant: Water Is Considered a Preferred Agent for Suppressing Lithium-Ion Batteries (PDF page 274, training slide 29)

Water is considered to be a preferred agent for suppressing lithium-ion batteries; Water has strong cooling capacity, easy to obtain, easy to transport to the fire site. Water fire fighting is widely used in putting out fire in scenarios of energy storage and electric vehicles.

Technical Deep Dive:

Water is identified as a preferred extinguishing agent for lithium-ion battery fires primarily because it can remove substantial amounts of thermal energy and can often be supplied in sufficient quantities.

Option B is correct. Water is generally accessible through firefighting water supplies, hydrants, emergency response vehicles, and other approved firefighting infrastructure.

Option C is correct. Water has excellent heat-absorption characteristics. Its relatively high specific heat capacity and latent heat of vaporization enable effective cooling of hot battery modules and surrounding structures.

Cooling is critical because lithium-ion battery thermal runaway can continue generating heat even after visible external flames have been suppressed.

Option D is correct. Firefighting water can be transported to affected installations using emergency response vehicles, hoses, pumps, and other suitable equipment.

Option A is not independently established as a separate characteristic. The term usability is broad and could refer to ease of application or operational convenience. However, the training passage specifically identifies cooling capacity, accessibility, and transportation.

It does not list general usability as an independent selection criterion.

In practice, battery firefighting must be conducted by appropriately trained emergency responders following the installation ' s approved emergency procedures. Personnel must consider electrical hazards, potential toxic gases, water runoff, and the risk of thermal runaway propagation.

Answer-key qualification: B, C, and D are directly supported. Option A is semantically ambiguous, so an answer key including A would require an additional definition of usability rather than an assumption.

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 — Definition and Classification of Dangerous Goods (PDF page 46, training slide 6)

Class 9 Miscellaneous dangerous substances and articles.

The classification diagram identifies lithium battery products and energy-storage systems under the Class 9 category and illustrates the corresponding dangerous-goods labels.

Technical Deep Dive:

Lithium batteries are classified as Class 9 miscellaneous dangerous goods under the United Nations dangerous-goods classification framework.

Option C is correct. Class 9 encompasses hazardous substances and articles that present risks during transportation but are not more appropriately classified under Classes 1–8.

Lithium batteries can present fire, electrical, and thermal hazards, particularly when damaged, improperly packaged, short-circuited, or exposed to excessive temperatures.

Relevant transport classifications include UN 3480 for lithium-ion batteries shipped separately and UN 3481 for lithium-ion batteries packed with or contained in equipment.

Other classifications may apply depending on the battery chemistry, product configuration, and transport arrangement.

Option A is incorrect. Class 2 primarily concerns gases.

Option B is incorrect. Class 1 covers explosives; lithium batteries are not classified as Class 1 merely because they can experience violent thermal failures.

Option D is incorrect. Class 3 covers flammable liquids rather than lithium batteries as complete transport articles.

Class 9 classification has practical implications for packaging, labeling, documentation, carrier qualifications, storage, and transportation requirements.

Certain smaller lithium batteries may qualify for specific regulatory exemptions or reduced requirements, but this does not change the underlying Class 9 hazard classification.

Final verification: C.

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 — Huawei Digital Power Corporate Quality Guideline (PDF page 116, training slide 9)

Doing the right thing means that we are adopting a right strategy. The quality will be certainly unsatisfactory on the basis a wrong strategy. We first need to make sure we are doing things in the right way.

In our work, we must strive to do things right at the first time, and efficiently deliver products of high quality.

We should understand and comply with processes, strictly follow processes, and ensure the certainty on results through the certainty on processes.

We need to continuously improve capabilities, be open to learning, and consolidate the iron triangle featuring the mutual reinforcement of organizations, capabilities, and processes, building a process- and capability-based organization.

Technical Deep Dive:

Huawei ' s principle of doing the right thing at the first time emphasizes making correct strategic decisions, following established processes, and preventing errors during initial execution.

Option A is the expected incorrect statement because it addresses the improvement of repair-return processes and defective-product handling rather than the specific elements listed under this quality guideline.

Repair quality and defective-product management are legitimate quality-management activities. However, the statement does not correspond to the defined components of doing the right thing at the first time.

Option B is correct. Continuous capability development and the mutually reinforcing relationship between organizations, capabilities, and processes form part of the guideline.

Option C is correct. Huawei emphasizes strict process compliance as a mechanism for achieving consistent and predictable quality outcomes.

Option D reproduces the guideline ' s stated strategy requirement. Selecting the correct strategy is essential because efficient execution cannot compensate for fundamentally incorrect strategic decisions.

The underlying quality-management principle is prevention rather than dependence on subsequent correction.

For SQA professionals, this means establishing effective controls before installation, ensuring personnel understand requirements, and preventing nonconformities from entering subsequent delivery stages.

Question interpretation: Option A is not inherently bad quality practice. It is incorrect specifically because it is not part of the quoted guideline ' s defined explanation.

Final verification: A.

Exact Extract — Process/Role Terms (PDF page 221, training slide 17)

Certified Service Partner (CSP). A CSP is a service partner who has passed Huawei ' s service certification. CSPs are responsible for the satisfaction of end customers to whom services are delivered.

Technical Deep Dive:

A Certified Service Partner is an organization that has fulfilled Huawei ' s applicable service certification requirements and is authorized to undertake defined service activities within its certification scope.

Option A is correct because both statements accurately reflect the CSP definition and associated customer satisfaction responsibility.

Service certification establishes that a partner meets specified service capability requirements. Depending on the certification, these may include professional qualifications, technical competencies, delivery procedures, management capabilities, and customer service requirements.

CSPs are responsible for delivering services in accordance with Huawei ' s standards and satisfying the expectations of the end customers receiving those services.

This responsibility includes maintaining service quality, complying with contractual commitments, controlling delivery risks, and responding appropriately to customer feedback.

The training also distinguishes CSPs from Authorized Service Partners (ASPs).

ASPs accept Huawei-outsourced service orders and deliver Huawei-branded services to end users. CSPs are characterized by their service certification and responsibility for the satisfaction of customers to whom their services are delivered.

For SQA personnel, evaluating partner performance includes monitoring qualifications, service process compliance, quality outcomes, customer feedback, and corrective actions.

Final verification: A.

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

Check the installation environment, including the installation position, foundation conditions, installation space, and warehousing conditions. If the requirements are not met, propose rectification and report the issue to the project owner.

Participate in the entry acceptance of equipment and materials, focus on the key points of unloading and handling, and ensure that the received equipment meets the installation requirements.

Technical Deep Dive:

Huawei ' s standard project delivery framework separates activities into preparation, construction, and completion phases. Each phase contains defined quality control and verification requirements.

Option A is correct. Device positioning is included in the construction phase. Equipment must be moved into its intended location according to approved engineering drawings, foundation conditions, clearance requirements, and handling procedures.

Option B is correct. Environmental checks are performed as part of construction-stage controls. The SQA must verify that installation and warehousing conditions satisfy the relevant product requirements before equipment is installed or placed into service.

Option C is incorrect when the phases are interpreted strictly. Technical and safety disclosure is classified under the preparation phase. It must be completed before construction entry, even though the disclosed requirements govern subsequent construction work.

Option D is correct. Onsite equipment installation is a principal construction-phase activity. It includes installing devices according to approved specifications and controlling installation quality, safety, and protection of finished products.

The distinction between preparation and construction is important for SQA process compliance. Technical disclosures, qualification checks, and quality planning establish the prerequisites for safe construction. Equipment positioning, installation, construction process monitoring, and quality inspections follow during execution.

Answer-key correction: The question-bank explanation groups all four activities into construction. The Huawei standard process on PDF pages 251–252 explicitly places technical and safety disclosure under Preparation, while environmental checks, device positioning, and onsite installation fall under Construction.

Final verification: A, B, and D are the correct selections when applying the training material ' s formal phase classification.

Exact Extract — Safety Operation Requirements 7/7: Electrolyte Contact Prevention (PDF page 190, training slide 49)

Electrolyte is corrosive and can cause irritation and chemical burns. In the case of electrolyte leakage or structural deformation, contact the installer or professional O & M personnel immediately to remove or replace the battery. Do not store the damaged battery near other devices or flammable materials and keep it away from non-professionals.

Technical Deep Dive:

Electrolyte leakage and structural deformation are serious indicators of potential battery damage and must be addressed immediately.

Option B is correct because it requires escalation to qualified installation or professional operation and maintenance personnel for appropriate removal or replacement.

Lithium-ion batteries contain electrochemical materials and internal structures that can become unsafe when exposed to impact, excessive heat, electrical faults, or other damaging conditions.

Electrolyte leakage can create chemical exposure hazards, while structural deformation may indicate damage to internal cells, separators, or electrical connections.

Such conditions may increase the risk of internal short circuits, overheating, gas release, or thermal runaway.

Option A is incorrect. Evaluating whether deformation affects installation is insufficient. A battery must not be considered safe merely because it can physically fit into the equipment.

Option C is incorrect. Attempting to install a damaged battery introduces unnecessary personnel and equipment risks.

Option D is incorrect. Inspecting electrolyte leakage alone does not constitute an adequate corrective action once leakage or structural deformation has already been identified.

Affected equipment should be isolated from normal handling activities, and the damaged battery must be kept away from unauthorized personnel and combustible materials.

Qualified personnel must follow the applicable battery manufacturer ' s handling and replacement procedures.

Final verification: B is directly supported by Huawei ' s battery safety requirements.

Exact Extract — Partner Successful Practice: Service Consistency Applied to a Financial Project (PDF page 218)

The customer ' s configuration and construction standards were met. The construction period was fixed and were not changed. The use of the office network on the next day was not affected.

The same case study states that the cutover window started at 00:00 on Saturday night and lasted five hours.

Technical Deep Dive:

Major service-affecting operations must be performed within an approved maintenance window to minimize operational disruption, control implementation risks, and provide sufficient time for verification and service restoration.

Option D is the expected answer. It establishes customer approval as the primary requirement and specifies 00:00–06:00 as a recommended low-traffic maintenance window.

Operations such as service cutover, configuration modification, board replacement, software loading, and power-off reset can temporarily interrupt services or introduce configuration inconsistencies.

Therefore, a controlled implementation procedure should include an approved change request, impact assessment, maintenance plan, rollback procedure, communication plan, and post-operation verification.

Performing such activities during a period of lower business activity can reduce the consequences of an unexpected interruption. However, the actual maintenance window must account for customer requirements, network utilization, geographic service coverage, and product-specific restrictions.

Option A proposes a fixed time interval without establishing customer approval as the overriding requirement.

Option B uses ordinary business hours, during which service interruptions may have greater operational consequences.

Option C is incorrect because high-risk service operations must not be performed arbitrarily.

For critical infrastructure, the governing product documentation and customer-approved maintenance procedure take precedence over a general recommended window.

Verification qualification: D is also the published answer for this question in the H20-688 practice bank. The uploaded Huawei training PDF demonstrates a midnight cutover, but does not explicitly establish 00:00–06:00 as a universal prescribed interval. Consequently, the exact six-hour recommendation is not independently verified from this PDF.
