IBM WebSphere Application Server Network Deployment V8.5 and V9.0, Core Administration — Question 4

What is the behavior of the default application class loader?

Answer options

• A. Classes from the parent are excluded.
• B. Classes are loaded from the parent first.
• C. Classes are loaded from the application first.
• D. Classes are compared between parent and application.

Correct answer: B

Explanation

The correct answer is B because the default application class loader follows the parent-first delegation model, meaning it attempts to load classes from the parent class loader before looking in its own class loader. Option A is incorrect as it suggests that parent classes are ignored, which is not true. Options C and D are also incorrect as they misrepresent the loading order and the comparison process of classes.
