Given a JSP page:
11.
<n:recurse>
12.
<n:recurse>
13.
<n:recurse>
14.
<n:recurse />
15.
</n:recurse>
16.
</n:recurse>
17.
</n:recurse>
The tag handler for n:recurse extends SimpleTagSupport.
Assuming an n:recurse tag can either contain an empty body or another n:recurse tag, which strategy allows the tag handler for n:recurse to output the nesting depth of the deepest n:recurse tag?

• A. It is impossible to determine the deepest nesting depth because it is impossible for tag handlers that extend SimpleTagSupport to communicate with their parent and child tags.
• B. If the tag has a body, invoke the fragment for that body.Otherwise, start a counter at 1. Call getParent(). If it returns null, output the value of the counter Otherwise, increment the counter and continue from where getParent() is called.
• C. Create a private non-static attribute in the tag handler class called count of type int initialized to 0. Increment count in the doTag method. If the tag has a body, invoke the fragment for that body. Otherwise, output the value of count.
• D. Start a counter at 1. Call getChildTags(). If it returns null, output the value of the counter. Otherwise, increment counter and continue from where getChildTags() is called. Skip processing of the body.

A JSP page needs to set the property of a given JavaBean to a value that is calculated with the JSP page. Which three jsp:setProperty attributes must be used to perform this initialization? (Choose three.)

• A. value
• B. property
• C. param
• D. attribute
• E. val
• F. id
• G. name

You are building JSP pages that have a set of menus that are visible based on a user's security role. These menus are hand-crafted by your web design team; for example, the SalesManager role has a menu in the file /WEB-INF/html/sales-mgr-menu.html. Which JSP code snippet should be used to make this menu visible to the user?

• A. <% if ( request.isUserInRole("SalesManager") ) { %> <%@ include file='/WEB-INF/html/sales-mgr-menu.html' %> <% } %>
• B. <jsp:if test='request.isUserInRole("SalesManager")'> <%@ include file='/WEB-INF/html/sales-mgr-menu.html' %> </jsp:if>
• C. <jsp:if test='request.isUserInRole("SalesManager")'> <jsp:include file='/WEB-INF/html/sales-mgr-menu.html' /> </jsp:if>
• D. <% if ( request.isUserInRole("SalesManager") ) { %> <jsp:include file='/WEB-INF/html/sales-mgr-menu.html' /> <% } %>

Which statement is true about web container session management?

• A. Access to session-scoped attributes is guaranteed to be thread-safe by the web container.
• B. To activate URL rewriting, the developer must use the HttpServletResponse.setURLRewriting method.
• C. If the web application uses HTTPS, then the web container may use the data on the HTTPS request stream to identify the client.
• D. The JSESSIONID cookie is stored permanently on the client so that a user may return to the web application and the web container will rejoin that session.

Which three are true about servlet filters? (Choose three.)

• A. A servlet may have multiple filters associated with it.
• B. A filter must implement the doFilter method.
• C. A servlet that is to have a filter applied to it must implement the javax.servlet.FilterChain interface.
• D. A filter that is part of a filter chain passes control to the next filter in the chain by invoking the FilterChain.forward method.
• E. A filter must implement the destroy method.
• F. For each <filter> element in the web application deployment descriptor, multiple instances of a filter may be created by the web container.
