Which port is used by HTTP to listen for secure connections?

A.
UDP 80

B.
TCP 443

C.
TCP 8080

D.
UDP 8080
1D0-470

Explanation:
No discussion, 443 is the default designated port for secured HTTP, which is usually invoked by using HTTPS.
Incorrect Answers:
A: Port 80 is used for non-secure HTTP, but it is TCP port 80, not UDP port 80, which is not use right now.
C, D: Services listen using ports below 1024, which are well known ports. These ports are above that range. TCP 8080 is sometimes used for a proxy port to connect into the proxy server, but is not defined as any standard.
