NO.3 A company is in the business of distributing hard candies. The distribution of these candies is
automated and the system that helps track information about candy distribution is written in Java

layer, but little is used. What is the best solution for the IT group to implement to provide the most flexibility
for the business unit?
A. refactor the DAOs to include additional static queries to pull information and export a
spreadsheet for the business unit to review

execute and display in HTML

database result in business logic changes to many JSPs. The single JSP developer, who was also the

interface to the application. You have been hired as the architect to refactor the web application. Which
two changes should you make to accomplish this? (Choose two.)
A. introduce a separate presentation layer with different views for HTML and XML
B. add an abstraction layer between the database and JSPs to encapsulate business logic

A. Generally, a given layer in one tier of this application should be concerned with the technology used in
the same layer of adjacent tiers.
B. To maximize separation of concerns, a given layer in a tier of this application should only have
knowledge of the adjacent layer in that tier.

know little or nothing of the layers below it.
D. If the layers in one tier of the application have been designed to achieve separation of
concerns, then the remaining tiers also achieve separation of concerns by default.
