Which of the following targets is more vulnerable to hacking attacks because of its location in relation to the firewall?

A.
DNS server

B.
FTP server

C.
E-mail server

D.
Router

Explanation:
The routers must often be physically placed outside the firewall. These routers are therefore vulnerable to hacker attacks.
Incorrect Answers:
A: The DNS server for the Intranet would be inside the firewall, and would communicate 1D0-470
with outside DNS servers using forwarding. DNS servers placed outside the firewall would be open to an attack, and usually zone transfers should not be allowed to pass the firewall (as a good practice)
B: A FTP server is usually provided by a company so that outside clients can access it and download documents and other files. The FTP server should be placed inside the firewall, and would not be vulnerable for attacks due to its location to the firewall.
C: The E-Mail server services the corporation. It may communicate through the firewall to receive and deliver mail from the Internet. The e-mail server is usually kept inside firewall so that the firewall can run scanning software to check the e-mail for proper addressing, and viruses.
