• Question 171:

  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.setSecure(true);12.
  B. setAge(10368000);13. response.addCookie(c);
  C. 10. Cookie c = new Cookie("creditCard", usersCard);11. c.setHttps(true);12.
  D. setMaxAge(10368000);13. response.setCookie(c);
  E. 10. Cookie c = new Cookie("creditCard", usersCard);11. c.setSecure(true);12.
  F. setMaxAge(10368000);13. response.addCookie(c);
  G. 10. Cookie c = new Cookie("creditCard", usersCard);11. c.setHttps(true);12.
  H. setAge(10368000);13. response.addCookie(c);
  I. 10. Cookie c = new Cookie("creditCard", usersCard);11. c.setSecure(true);12.
  J. setAge(10368000);13. response.setCookie(c);
  C. 10. Cookie c = new Cookie("creditCard", usersCard);11. c.setHttps(true);12.

• Question 175:

  You are creating a JSP page to display a collection of data. This data can be displayed in several different ways so the architect on your project decided to create a generic servlet that generates a comma-delimited string so that various

  objectID. Assume that this servlet is mapped to the URL pattern: /WEB- INF/data.

  In the JSP you are creating, you need to split this string into its elements separated by commas and generate an HTML

  list from the data.

  Which JSTL code snippet will accomplish this goal?

  A. $ {item}
  B. $ {item}
  C. $ {item}
  D. $ {item}
  D. $ {item}
