Questions from the IBM 287 sample test

[Bricex Lin]

Two enterprise applications use a third party software (like Apache Xerces). While the actual
versions of the third party software used are different between the two applications, the name
of the JAR files across different versions is the same. To ensure proper running of these
enterprise applications, which of the following should be used in WebSphere Application
Server, V5.0 for application classloading policy ?

A. SERVLET ENGINE

B. SERVER

C. APPLICATION

D. MULTIPLE

E. SINGLE
Select the best answer.
My answer is D, but somebody said the answer is E. Could anybody explain this question? Thanks in advance.

The question is pretty straightforward. Just nothing to explain.

BL,
Our Naming Convention states that you must have a realistic first and last name. Please change your display name in your profile to conform to this simple rule.
Thanks!

Serge,
Could you explain a little bit, since you feel the question is pretty straightforward. Your previous input means nothing, it was just time wasting for you to input.

I think Lin was right.
"MULTIPLE" class-loading policy should be selected.
Since multiple means each app will have its own classl loader, single means all applications in the entire system will share the same class loader
