Using the second Law of Newton, F = m * a, you know that acceleration is maximum when the force is maximum.
Using Hooke's Law, F = K Δx, you know that the force is maximum when the displacement from the equilibrium (Δx) is maximum.
So the answer is that the acceleration is maximum at the maximum amplitude x = a.
