For rendering: The maximum voxel buffer size is 32768 in each dimension (X, Y and Z), and the limit on the number of voxels is 1 trillion. This only affects lighting; voxels are not directly visible to the camera.
For VDB export: The exact dimensions and voxel positions could be slightly different from the buffer used for rendering, but should be quite close. The buffer is built with voxels that have approximately the same size as those used for rendering, and for most clouds you can expect the VDB buffer to be based on approximately the same resolution as the render buffer.
However, most cloud layers have more empty space than filled space, so you should expect the number of non-empty voxels in the VDB to be much lower than the number you enter into the GUI. I don't think there are any other limits on resolution, except for limits of the VDB file format.
