Your photo does not look overexposed to me. Sure, the sky is blown. But the water at the bottom is already black. And the church looks just right, which is probably what you focused on. The D7000 takes the point of focus into account when metering. Try using AF-S with a single focus point on a scene with brighter and darker elements. The photo will be exposed differently depending on what you focused on.
If the camera had reduced the exposure to make the sky come out just right, the buildings would have been way too dark. If that's what you wanted (perhaps to add some fill light in Lightroom later), either point the camera to the sky, hold down AEL, recompose, and shoot. Or, dial in negative exposure compensation.
The D7000 can adjust aperture and shutter speed in 1/3 EV steps. In auto ISO mode, it can adjust ISO in 1/6 EV steps. If auto-exposure gets it within 1/3 EV of what I wanted, I'd consider that an excellent result.
That said, I do find that in bright sunny conditions, my D7000 often exposes my photos more than I'd like. My solution is to set the drive dial to H and to set bracketing to take one photo as metered and one with -2/3 EV (hold down the BKT button and use the two dials to dial in -2 and 0.7). The D7000 then rapidly takes two shots for each (sufficiently long) press of the shutter button. When importing my photos, I'll choose one from each pair.
There is actually a benefit to brightly exposing photos. The brighter parts of the photo have less noise. In bright conditions where you can increase exposure without increasing ISO or using too slow a shutter speed (subject movement), you're better off with a picture that's too bright (as long as you're not blowing too many highlights) than one that is too dark. Making a picture brighter in post increases noise, but making it darker does not.
