You have a new IT manager that has mandated that all JSPs must be refactored to include no scriptlet code.
The IT manager has asked you to enforce this.
Which deployment descriptor element will satisfy this constraint?

• A.<jsp-config><url-pattern>*.jsp</url-pattern><permit-scripting>false</permit-scripting></jsp-config>
• B.<jsp-property-group><url-pattern>*.jsp</url-pattern><permit-scripting>false</permit-scripting></jsp-pro
• C.<jsp-property-group><url-patterm>*.jsp</url-pattern><scripting-invalid>true</scripting-invalid></jsp-pro
• D.<jsp-config><url-pattern>*.jsp</url-pattern><scripting-invalid>true</scripting-invalid></jsp-config>

You are building your own layout mechanism by including dynamic content for the page's header and footer sections. The footer is always static, but the header generates the <title> tag that requests the page name to be specified dynamically when the header is imported.
Which JSP code snippet performs the import of the header content?

• A.<jsp:import page='/WEB-INF/jsp/header.jsp'><jsp:attribute name='pageName' value='Welcome Page'
  /></jsp:import>
• B.<jsp:include page='/WEB-INF/jsp/header.jsp'><jsp:param name='pageName' value='Welcome Page'
  /></jsp:include>
• C.<jsp:import page='/WEB-INF/jsp/header.jsp'><jsp:param name='pageName' value='Welcome Page'
  /></jsp:import>
• D.<jsp:include page='/WEB-INF/jsp/header.jsp'><jsp:attribute name='pageName' value='Welcome Page' /></jsp:include>

When using Servlet asynchronous API if you want to dispatch the request back to a particular url - "url" within the same ServletContext which of the following API would you use?

• B.AsyncContext.dispatch(servletContext, "/url");

• D.RequestDispatcher.include("/url");
• E.RequestDispatcher.forward("/url");
• F.AsyncContext.dispatch("/url");
• G.AsyncContext.start(runnable);

Given this fragment in a servlet:
23. if(reg.isUserInRole("Admin")) {
24. // do stuff
25. }
And the following fragment from the related Java EE deployment descriptor:
812. <security-role-ref>
813. <role-name>Admin</role-name>
814. <role-link>Administrator</role-link>
815. </security-role-ref>
900. <security-role>
901. <role-name>Admin</role-name>
902. <role-name>Administrator</role-name>
903. </security-role>
What is the result?

• A.Line 24 can never be reached.
• B.If line 24 executes, the user's role will NOT be predictable.
• C.If line 24 executes, the user's role will be Administrator.
• D.If line 24 executes, the user's role will be Admin.
• E.The deployment descriptor is NOT valid.
