A team is developing a safety-critical system where a failure could have severe consequences. They have limited time and budget. Which testing strategy best balances thoroughness and resource constraints?

Prioritize risk-based testing, focusing on high-risk components and critical paths

Skip non-functional testing to focus on functional correctness

Rely solely on automated testing to save time

Perform exhaustive testing of all possible inputs and scenarios

A QA team is managing defects for a large project. They have a backlog of 200 defects. The team has limited development resources and must decide which defects to fix first. The project manager wants to minimize the risk of customer impact. Which approach should the team use to prioritize defects?

Prioritize defects by the number of lines of code affected

Prioritize defects by the order they were reported

Prioritize defects by severity and frequency of occurrence

Prioritize defects by the tester who found them

A QA manager wants to report on the quality of a release candidate. The team has executed 800 test cases, of which 120 failed. The application has 50,000 lines of code, and 25 defects were found during this test cycle. Which metric should the manager use to communicate the density of defects in the code?

Defect density = 25 / 50,000 = 0.0005 defects per line of code

Test coverage = 800 / 50,000 = 1.6%

Defect removal efficiency = 25 / (25 + 0) = 100%

Test pass rate = (800 - 120) / 800 = 85%

Part of the Application Development and Security Fundamentals domain, which makes up ~20% of our current practice bank. EC-Council does not publish an official question count, but from its 120-minute exam (~50–80 total, ~10–16 in this domain), expect 2–3 from this objective — we provide 40 practice questions to prepare you well beyond it.
