that is A(add9). It is an A major chord with a B note thrown in for colour. Rather nice! It can also be played like this

5 7 7 6 0 0

or this:

x 0 2 4 2 0

or even this:

x 0 11 9 0 0

Just to clarify:

"add 9" chords NEVER include the 7th. This is what the "add" bit means. Amaj9, Am9 or A9 all must include the 7th. The "add" tells you it as the chord (usually a triad) shown PLUS the interval shown, with no un-specified extensions.

e.g. Em(add9) = 0 2 4 0 0 0 or 0 2 2 0 0 2

Em9 = 0 2 4 0 3 0 or 0 2 0 0 0 2

It is not A major sus2. There is no such cord. Sus chords are neitehr major or minor. By definition the 3rd has been replaced with a 2nd.
