210-255 Question #107: Real Exam Question with Answer & Explanation

The correct answer is B: Deterministic analysis uses data known beforehand and probabilistic analysis based off of. Deterministic analysis (B) uses data and facts that are known beforehand - inputs produce predictable, repeatable outputs with certainty (e.g., a hash match definitively identifies a file). Probabilistic analysis (E) produces results that are not definitive - it uses statistical

Question

Which two potions about deterministic and probabilistic analysis are true? (Choose two.)

Options

Aprobabilistic analysis uses data known beforehand and deterministic analysis is based off
BDeterministic analysis uses data known beforehand and probabilistic analysis based off of
CDeterministic analysis is based off of assumptions
DProbabilistic analysis result in a result that is definitive.
Eprobabilistic analysis results in a result that is not definitive.

Explanation

Deterministic analysis (B) uses data and facts that are known beforehand - inputs produce predictable, repeatable outputs with certainty (e.g., a hash match definitively identifies a file). Probabilistic analysis (E) produces results that are not definitive - it uses statistical models, likelihood scores, and inferences to assign a probability to an outcome rather than a guaranteed answer (e.g., a behavioral analytics engine flagging an anomaly as '85% likely malicious'). Option A reverses the definitions, making it incorrect. Option C is wrong because deterministic analysis is based on known facts, not assumptions. Option D is wrong because it is probabilistic analysis - not deterministic - that produces non-definitive results, making D's claim the opposite of truth.
