NO.4 A company architected and developed a Java EE application and now they are having problems with
the scalability of the system. The application uses JSPs and servlets deployed to a web container, and
stateless session beans and DAOs deployed to an EJB container. The application's non-functional
requirement for scalability is to support 500 concurrent users during peak hours of operation. The
application can currently support 500 concurrent users, but the response time is 200 percent of what it is
acceptable. You have been hired as an architect and have been assigned to help resolve this problem.
The company's management is concerned with the hardware budgeting. What initial advice would you
give to the company?
A. add another web server
B. start a new project to re-architect the application

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

produce results in a given format
C. provide a JSP page, which has scriptlets that expose pre-defined queries for the business unit to
execute and display in HTML
D. create a web service that exposes fixed queries invoked by a JSP client that can pull data from the
database and export in a given format

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
