OpenGL - glVertexAttribPointer with multiple VBOs and VAOs using the same shader

I have multiple VBOs and matching VAOs set up in my rendering engine. I am a bit confused about using glVertexAttribPointer. I have set it and it renders fine but I am curious if I am using one shader (a basic diffuse) with all of these different objects, do I set glVertexAttribPointer each time I create a VAO. I guess what's throwing me is I am trying to figure out if my setting an attribute pointer, is that set in the shader or the vertex array object. I assume it's the vertex array object but am hoping for some clarification.

Vertex attribute pointers are per vertex array object (VAO). The OpenGL 4.3 specification on page 318 in the description of glGetVertexAttribPointerv specifies: The value returned is queried from the currently bound vertex array object.
