Examination Questions & Rationales (75 Items)
Question 1.
Which fundamental principle serves as the primary operational foundation in "June 2025 AQA A-Level Design and
Technology 7552/1 Paper 1 Technical Principles – QP & Mark Scheme"?
A) Strict adherence to empirical evidence, structured protocols, and validation testing
B) Relying entirely on unverified assumptions without measurement baselines
C) Eliminating iterative review cycles in favor of expedited single-pass execution
D) Prioritizing arbitrary subjective preference over standardized safety benchmarks
Correct Answer: A
Rationale: Evidence-based protocols and validated testing ensure repeatable quality, minimize risk, and safeguard systemic
integrity. Distractor options (B, C, D) represent clinically or methodologically incorrect choices that fail to address the
core safety and diagnostic priorities.
Question 2.
When troubleshooting systemic anomalies in "June 2025 AQA A-Level Design and Technology 7552/1 Paper 1 Technical
Principles – QP & Mark Scheme", which step should the analyst execute FIRST?
A) Completely dismantle the entire architecture without recording the fault condition
B) Gather objective diagnostic data and isolate variables from the baseline state
C) Dismiss user reports and assume normal operational status
D) Apply random configuration updates until a transient change is observed
Correct Answer: B
Rationale: Systematic troubleshooting starts with objective data collection to isolate the root cause before attempting
interventions. Distractor options (A, C, D) represent clinically or methodologically incorrect choices that fail to address
the core safety and diagnostic priorities.
Question 3.
In evaluating performance metrics for "June 2025 AQA A-Level Design and Technology 7552/1 Paper 1 Technical Principles
– QP & Mark Scheme", which indicator provides the MOST reliable gauge of systemic stability?
A) Extreme fluctuations in output frequency with high error rates
B) Total absence of operational logs or telemetry data
C) Consistent throughput within calibrated tolerance bands under variable workloads
D) Single-point measurement taken during an unrepresentative idle period
