Which of the following would indicate a fast tempo?

Answer 1

A fast two will become nothing more than a one beat. A moderately fast tempo in a three meter may prevent a conductor from conveying all three beats comfortably.

There are times when a conductor will question whether he should be conducting in two instead of four, for instance, or in one instead of three. Sometimes a tempo will seem to be too fast to conduct in three, but slightly too slow to conduct in one without losing control over beats two and three. There is never one simple answer for these questions. Each example must be dealt with on its own merits.

Answer 2

Allegro. vivace is lively and presto is very fast. faster than that would be prestissimo.
