An employee is receiving an error message when she tries to open a Web page. The error states “Web page requested is not available.” You note that https:// appears in the address bar. You confirm that the site is up and running by accessing it from a computer outside your corporate network. Which of the following should you do to fix this problem?
  1. Allow traffic on TCP port 443.
  2. Allow traffic on TCP port 53.
  3. Configure the default IPSec Client (Respond Only) policy on the client computers.
  4. The Web server hosting the Web page is down.
Explanation
Answer - A - To fix this problem, you should allow traffic on TCP port 443.

Key Takeaway: The message “Web page requested is not available” indicates an encryption problem when https:// appears on the address bar. Web page encryption is implemented using the Secure Sockets Layer (SSL) protocol. This protocol uses TCP port 443. Hence you should allow traffic on TCP port 443.
