NO.1 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
C. monitor the application to determine the potential problem areas
D. add more memory and processors to the hardware hosting the EJB container
