1. 1An auditor evaluates whether a heat-treatment operation follows its approved temperature, time, and control instructions. Which audit type best describes the object being evaluated?

   1. A. Product audit
   2. B. Process audit
   3. C. System audit
   4. D. Management audit

   Answer: B

   Explanation: ASQ describes process audits as verifying that "processes are working within established limits." The operation and its controls are the audit object.

   Reference: What Is Auditing? — ASQ — The Three Different Types of Audits / Process audit

2. 2Before an unannounced audit is conducted, which preparation establishes the team's legitimate basis for entering and evaluating the activity?

   1. A. Documenting the planned scope and audit objectives
   2. B. Documenting the authority to conduct the audit
   3. C. Documenting the time budget and staffing allocation
   4. D. Documenting the proposed sequence of audit activities

   Answer: B

   Explanation: EPA states, "The authority to conduct the audit must be documented in this meeting." Surprise does not remove the need for documented authorization.

   Reference: Guidance on Technical Audits and Related Assessments for Environmental Data Operations — EPA QA/G-7 — Section 3.1.4, p.27 / unannounced audit

3. 3An auditor starts a new assignment expecting failure because of the department's reputation. Which characteristic should the auditor demonstrate instead?

   1. A. Loyalty to the previous audit team's interpretation
   2. B. Persistence in proving the initial expectation
   3. C. Open-minded evaluation without preconceived conclusions
   4. D. Preference for evidence that agrees with the reputation

   Answer: C

   Explanation: EPA states, "The auditor should not begin the audit with preconceived notions." An open-minded attitude permits evaluation of the current evidence.

   Reference: Guidance on Technical Audits and Related Assessments for Environmental Data Operations — EPA QA/G-7 — Section 2.4.2, p.19

4. 4Management approves an audit programme but allocates no time, personnel, or funding to execute it. Which management support is missing?

   1. A. Formally defining the audit function's authority and reporting line
   2. B. Approving the policy that establishes the organization's audit programme
   3. C. Providing the personnel, time, and funding needed to execute the programme
   4. D. Approving a standard format for communicating the programme's audit results

   Answer: C

   Explanation: EPA states, "Management should ensure that adequate resources are available for the audit program." Approval without means of execution is insufficient support.

   Reference: Guidance on Technical Audits and Related Assessments for Environmental Data Operations — EPA QA/G-7 — Section 2.5, p.21

5. 5A team has counts for ten types of audit-related errors and wants to focus on the categories contributing the most errors. Which tool ranks those categories by frequency?

   1. A. Scatter diagram
   2. B. Control chart
   3. C. Flowchart
   4. D. Pareto chart

   Answer: D

   Explanation: ASQ describes bars arranged "with longest bars on the left and the shortest to the right." This ranked display highlights the largest contributors.

6. 6An audit examines a finished software release against its specified functional and customer requirements. How is this audit classified by its object?

   1. A. System audit
   2. B. Department audit
   3. C. Management audit
   4. D. Product audit

   Answer: D

   Explanation: ASQ's product-audit definition states, "This type of audit is an examination of a particular product or service, such as hardware, processed material, or software, to evaluate whether it conforms to requirements." The finished software release is the output being evaluated, so D is the product audit rather than an evaluation of process execution or the wider system.

7. 7A planned audit requires expertise in both analytical chemistry and data systems. How should the audit team be selected?

   1. A. Require each member to have identical expertise in both disciplines.
   2. B. Select only general auditors and rely on the auditee for technical judgments.
   3. C. Ensure the team collectively has the needed audit and subject expertise.
   4. D. Select the most available employees regardless of the audit's scope.

   Answer: C

   Explanation: EPA says the team as a whole should possess "the needed audit expertise and subject matter knowledge for the scope of the audit." Complementary competence is sufficient; identical expertise is unnecessary.

8. 8An auditee is slow to supply information the auditor is authorized to request. Which personal attribute supports obtaining the information without exceeding the auditor's role?

   1. A. Persistence within the auditor's defined authority
   2. B. Willingness to claim authority beyond the audit assignment
   3. C. Readiness to accept missing evidence without further inquiry
   4. D. Preference for replacing records with personal assumptions

   Answer: A

   Explanation: EPA calls for being "persistent in obtaining the necessary information to the extent of the auditor’s defined authority." Persistence is bounded by legitimate authority.

   Reference: Guidance on Technical Audits and Related Assessments for Environmental Data Operations — EPA QA/G-7 — Section 2.4.4, p.21

9. 9A programme budget allows time for site visits but none for preparation, reporting, or specified follow-up. What should be changed?

   1. A. Include the time needed across the full audit work cycle.
   2. B. Count site hours twice to represent the omitted work.
   3. C. Treat report preparation as an auditee responsibility.
   4. D. Eliminate follow-up from the budget regardless of the plan.

   Answer: A

   Explanation: EPA says auditors need time to "prepare for the audit, conduct the audit, generate the findings report, and perform any specified verification of corrective actions." The budget should reflect these activities.

   Reference: Guidance on Technical Audits and Related Assessments for Environmental Data Operations — EPA QA/G-7 — Section 2.6.2, p.22

10. 10Which tool helps a team organize potential causes of a quality problem into categories before investigating them?

    1. A. Histogram
    2. B. Cause-and-effect diagram
    3. C. Run chart
    4. D. Acceptance sampling plan

    Answer: B

    Explanation: ASQ describes a fishbone diagram as "sorting ideas into useful categories." It organizes possible causes rather than proving which cause is responsible.
