Java Server Pages (JSP 1.1), Question 40 of 40
his question (one per test)
Scenario
A banking application has been written that stores current context in a
Sessionlevel bean. The typical data stored in the context is the current
user name and current account being viewed.
Referring to the above scenario, what defect does this application suffer
from because of how it is using the Sessionlevel bean?
Choice 1
If the user does not log out, then the information stored in the context
will remain in the Web Server until the user next logs on.
Choice 2
Storing information in this way may open a security hole that allows
hackers to retrieve user information very easily.
Choice 3
The information concerning the account the customer is viewing because the
account number is not stored in the Requestlevel bean.
Choice 4
Storing this information on the Web Server is likely to increase the burden
on the Web Server, damaging performance.
Choice 5
Use of a Web browser's Back button could cause operations to be carried out
against the wrong account.

Java Server Pages (JSP 1.1), Question 26 of 40
his question (one per test)
Scenario
A Web Application written using JSP pages makes use of Wizardstyle
walkthroughs to aid users whenever they make complicated changes. A change
to the ordering of each JSP page in the Wizard takes over 3 hours to
complete. This is unacceptable for such a trivial and common operation.
Given the above scenario, what is a possible approach for reducing the
time taken to change the ordering of pages?
Choice 1
Implement the JSP pages using a templating scheme.
Choice 2
Do not share JSP pages between Wizards.
Choice 3
Use a Servlet to abstract the difference between page control and page
visualization.
Choice 4
Implement the JSP pages with more embedded scriptlets designed to make page
ordering easier to change.
Choice 5
Implement the JSP pages using a Model 1 architecture.
Java Server Pages (JSP 1.1), Question 25 of 40
his question (one per test)
Statement
A JSP page is compiled into a Servlet; therefore, it can do everything that
a Servlet can do.
If the above statement is TRUE, then why is an IllegalStateException
thrown when opening a Binary Stream output to the client from a JSP page but
NOT to a Servlet?
Choice 1
JSP pages can write a Binary Stream using its implicit out stream.
Choice 2
JSP pages use a different Streaming mechanism to Servlets.
Choice 3
JSP pages must flush their buffers before changing the stream type;
Servlets do not have this limitation.
Choice 4
JSP pages have more security settings than Servlets.
Choice 5
JSP has already opened the stream as a JspWriter.
Java Server Pages (JSP 1.1), Question 24 of 40
his question (one per test)

When a custom tag implements the BodyTag Interface, how does the JSP
Engine handle nested tags?
Choice 1
The contents of the nested tags are sent to the browser in a breadth first
traversal of the nested hierarchy.
Choice 2
The output of a nested tag is sent to a buffer that the parent tag can see.
Choice 3
It is the responsibility of the nested tag to pass information to its
parent tag.
Choice 4
The contents of the nested tags are sent to the browser in a depth first
traversal of the nested hierarchy.
Choice 5
JSP does not support nested tags.

Java Server Pages (JSP 1.1), Question 21 of 40
his question (one per test)
Scenario
In a banking Web Application, a customer can view his or her current bank
details and transfer money between accounts. When a user logs on, a
