Which pattern indicates a Test failure event?

• A. Continuous, slow, beeping alarm sound
• B. No alarm sound
• C. Three short, high beeping alarm sound
• D. Continuous, slow, two-tone beeping alarm sound

Answer: (D)

Alarm patterns use duration, tempo, and tone to convey event type. For a Test failure event, the system uses a persistent, slow, two-tone signal. The continuous nature shows the issue remains unresolved, while the slow pace emphasizes seriousness without an abrupt, high-speed alert. The two-tone combination makes this pattern stand out from other alerts, signaling a failure specifically rather than a general warning. The other patterns lack this distinctive two-tone cue or indicate different statuses (no alarm means no event; a brief or single-tone pattern points to a different notification).
