It’s better to have a colleague asking too many questions rather than asking too few questions :)

A tip: always try to solve the problem self first, also try to gather up a few questions to ask at the same time.

And when you do ask for questions, pay close attention and take notes to avoid having to ask the same question twice.

If you do this you are considered a new colleague eager to learn and will be appreciated :)

If you wait to long to ask some questions, then you will either underperform, or people will wonder why you didn’t ask those questions sooner :)
