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

the same layer of adjacent tiers.

knowledge of the adjacent layer in that tier.
C. For any given tier, separation of concerns is fulfilled when a given layer in that tier knows or needs to
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.
