Do you need a child's birth certificate when flying to Nha Trang with a minor, and what do border officers ask?

TL;DR

When departing Russia with a child, border control almost always asks for the birth certificate, especially if surnames differ; on arrival in Vietnam there are usually no questions.

What the community said

Even with the same surname as the child, if you fly frequently, expect the birth certificate to be checked on both departure and arrival every time until the child turns 18. Keep the document in good condition since frequent travelers wear it out quickly.

Even with matching surnames, officers don't always ask for the birth certificate — but sometimes they do, and may also question your exact relationship to the child.

If the adult and child have different surnames, Russian departure control will definitely ask for the birth certificate; on arrival in Vietnam there were no questions at all.
