By default, what port does a web server use when using SSL?

A. 80

B. 8080

C. 443

D. 21

Explanation:
Because personal information such as credit-card numbers can be sent over the Internet, a supplemental
protocol was developed called Secure Sockets Layer (SSL). This protocol uses TCPport443, which uses a
digital certificate to encrypt the packet so that it cannot be read by anyone else except the source and
target. When you use SSL, the browser URL starts with https (for example, https://www.acme.com).
