Question 1: How would you structure a report summarizing multiple test cycles on the same system to assess overall reliability?

Which action should you take?

Choose only one option

By detailing each failure point with specific test instances

By reporting only the best result per cycle

By listing each test result separately and categorizing by time

By comparing the performance trends across all cycles

Question 2: To detect intermittent failures in a high-speed circuit, what is the most effective data analysis approach?

Which action should you take?

Choose only one option

Apply a fault tree analysis and check components for failure

Use continuous monitoring without statistical analysis

Use high-speed oscilloscopes and statistical analysis of failure occurrences

Perform a simple visual inspection to identify faults

Question 3: When planning for functional testing of an embedded system, what is the most effective method for boundary condition testing?

Which action should you take?

Choose only one option

Ensuring full integration testing of all subsystems

Using random inputs to observe the system's response

Identifying all input/output ranges and verifying correct system behavior at extremes

Testing with a wide variety of data sets at all system levels

Question 4: In a safety-critical system test, which aspect would you primarily focus on?

Which action should you take?

Choose only one option

Ensuring the system meets performance specifications

Validating the user interface for ease of use

Verifying compliance with safety standards and certifications

Testing the power efficiency of the system

Question 5: In a test plan for a microprocessor-based product, which of the following factors should be tested first during the validation phase?

Which action should you take?

Choose only one option

External peripheral communication

Power-up performance under different input voltages

Signal processing accuracy

Boot-up reliability and initialization sequences

Question 6: During a functional test of a microcontroller, what is the most important factor to monitor?

Which action should you take?

Choose only one option

The thermal performance of the microcontroller

The correctness of the I/O response to various inputs

The speed of the communication bus used
