I found this question in one of the Mock
test.
----------------------------------------------
You are developing an online shopping store for an art gallery. The company aims to bring fine art to the masses and expects a huge volume of traffic through the site. The site allows customers to pay for goods and arrange delivery methods using credit
cards. You have read through the requirements and have a rough design in your head. Which of the following is the most appropriate rough design for this site?
AHave an Entity Bean to represent the customer. Use a
Servlet to manage the users session and use BMT to manage the transactions.
BHave an Entity Bean to represent the customer. Use a Stateful Session Bean to manage the users session and use BMT to manage the transactions.
CHave an Entity Bean to represent the customer. Use a Servlet to manage the users session and use CMT to manage the transactions.
DHave an Entity Bean to represent the customer. Use a Stateful Session Bean to manage the users session and use CMT to manage the transactions.
-----------------------------------------
As per my understanding correct answer should be D. But as mock test, C is correct answer. Please suggest.
