What is true of it
Dsus2 is D, E and A — 1, 2 and 5 counted from D.
These are also the notes of Asus4/D. Which name is right depends on what is underneath and what came before — the notes alone do not decide.
The easiest of the 5 fingerings below is xx0230: 2 fingers, held at the 2nd fret.
1 of them use open strings, which is what makes a shape quiet to change to.
2 strings stay silent.
Where its notes are on the neck
The brass dots are D, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
