Hi,
Came across this
thread while preparing for the exam. The reason I am replying to such an old thread right now is because I think the jury is still out on this one.
Here's why. Oracle's OCMJEA 5 website has a sample question on similar lines. The question asks how does the NFR improve with changing to a 3-tier model. The answer is not "manageability" and the explanation for that says: "Option C is incorrect because manageability of one-tier application is generally easier than tree-tier application. With a three-tier you need to manage the health the web server, application server, and database". This is in direct contradiction with Cade's book. I would not be taking it seriously but this comes from Oracle's website! You can take a look at Question 2:

Any thoughts, welcome.
