質問 4：
You have built a web application with tight security. Several directories of your webapp are used for internal purposes and you have overridden the default servlet to send an HTTP
403 status code for any request that maps to one of these directories. During testing, the
Quality Assurance director decided that they did NOT like seeing the bare response page generated by Firefox and Internet Explorer. The director recommended that the webapp should return a more user-friendly web page that has the same look-and-feel as the webapp plus links to the webapp's search engine. You have created this JSP page in the
/WEB-INF/jsps/error403.jsp file. You do NOT want to alter the complex logic of the default servlet. How can you declare that the web container must send this JSP page whenever a
4 03 status is generated?
A. <error-page>
< status-code>403</status-code>
< url>/WEB-INF/jsps/error403.jsp</url>
< /error-page>
B. <error-page>
< error-code>403</error-code>
< location>/WEB-INF/jsps/error403.jsp</location>
< /error-page>
C. <error-page>
< status-code>403</status-code>
< location>/WEB-INF/jsps/error403.jsp</location>
< /error-page>
D. <error-page>
< error-code>403</error-code>
< url>/WEB-INF/jsps/error403.jsp</url>
< /error-page>
正解：B

'myTags' and 'moreTags'.
B. The URI 'myTags' must be properly mapped to a TLD file by the web container.
C. The prefix 'java' is reserved.

質問 6：
Which is true about the web container request processing model?
A. A filter defined for a servlet must always forward control to the next resource in the filter chain.
B. The init method on a filter is called the first time a servlet mapped to that filter is invoked.
C. If the init method on a filter throws an UnavailableException, then the container will make no further attempt to execute it.
D. Filters associated with a named servlet are applied in the order they appear in the web application deployment descriptor file.
正解：D

質問 7：
Your company has a corporate policy that prohibits storing a customer's credit card number in any corporate database. However, users have complained that they do NOT want to re- enter their credit card number for each transaction. Your management has decided to use client-side cookies to record the user's credit card number for 120 days. Furthermore, they also want to protect this information during transit from the web browser to the web container; so the cookie must only be transmitted over HTTPS.
Which code snippet creates the "creditCard" cookie and adds it to the out going response to be stored on the user's web browser?
A. 10. Cookie c = new Cookie("creditCard", usersCard);
11. c.setHttps(true);
12. c.setAge(10368000);
13. response.addCookie(c);
B. 10. Cookie c = new Cookie("creditCard", usersCard);
1 1. c.setHttps(true);
1 2. c.setMaxAge(10368000);
1 3. response.setCookie(c);
C. 10. Cookie c = new Cookie("creditCard", usersCard);
1 1. c.setSecure(true);
1 2. c.setMaxAge(10368000);
1 3. response.addCookie(c);
D. 10. Cookie c = new Cookie("creditCard", usersCard);
1 1. c.setSecure(true);
1 2. c.setAge(10368000);
1 3. response.setCookie(c);
