                                          23.
                                          <!-- and more options -->
                                          After the user submits this form, a confirmation screen is displayed with these hobbies listed. Assume that an application-scoped variable, hobbies, holds a map between the Hobby enumerated type and the display name.
                                          Which EL code snippet will display Nth element of the user's selected hobbies?

                                          A) ${hobbies[paramValues@'hobbyEnum'@N]}
                                          B) ${hobbies[paramValues.hobbyEnum[N]]}

                                          3. Which statement is true about web container session management?

                                          A) 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.
                                          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) Access to session-scoped attributes is guaranteed to be thread-safe by the web container.


                                          4. Which EL expression evaluates to the request URI?

                                          A) ${request.requestURI}
                                          B) ${request.URI}
                                          C) ${requestURI}
                                          D) ${requestScope.request.requestURI}
                                          E) ${requestScope.requestURI}
                                          F) ${request.getURI}
                                          G) ${pageContext.request.requestURI}


                                          5. In a JSP-centric web application, you need to create a catalog browsing JSP page. The catalog is stored as a List object in the catalog attribute of the webapp's ServletContext object. Which scriptlet code snippet gives you access to the catalog object?

                                          A) <% List catalog = servletContext.getAttribute("catalog"); %>
                                          B) <% List catalog = context.getAttribute("catalog"); %>
                                          C) <% List catalog = application.getAttribute("catalog"); %>
                                          D) <% List catalog = config.getAttribute("catalog"); %>

                                          Without your 1Z0-858 practice guide, i wouldn't get ready enough for the exam and pass it. You are doing great!

                                          I learned from 1Z0-858 book and I am happy to practice this 1Z0-858 study test as a base for a real test. I passed on June 6, 2018. I failed one last 3 months ago and the test is completely different in a second round. Thank you!
