This sound is identified as Quiz Sting (full mix) by composer Terry Devine-King, a well-known writer of production music used in television and media. Rather than coming from a single famous scene or character, it fits the long-running quiz show style of short musical cues used for reveals, transitions and timed questions. Online, sounds like this stay popular because creators use them to instantly signal suspense, competition and an answer reveal without needing a full music bed.
