Answer: A - John should enable InPrivate Browsing if he does not want to keep track of websites browsed during the browsing session.
Key Takeaway: InPrivate Browsing in Windows Internet Explorer 8 helps protect data and privacy by preventing browsing history, temporary Internet files, form data, cookies, and usernames/passwords from being stored or retained locally by the browser. This leaves no evidence of the user’s browsing or search history. You can start InPrivate Browsing in Internet Explorer 8 from the new Safety menu by selecting Start InPrivate Browsing from a New Tab page or at a command prompt.
