CompTIA Server+ (SK0-005)Server AdministrationEasy
A server administrator is configuring a new web server to host several secure websites. To ensure that client browsers can establish encrypted connections, the administrator must install and configure server certificates. What is the standard TCP port used by web servers for secure HTTP (HTTPS) communication?
- A80
- B443
- C3389
- D21
Show answer & explanationAnswer & explanation
Correct answer: B. 443
HTTPS (Hypertext Transfer Protocol Secure) uses TCP port 443 for encrypted communication, ensuring secure data exchange between the web server and clients.
Why the other options are wrong
- A. Port 80 is used for standard HTTP (unencrypted web traffic), not HTTPS.
- C. Port 3389 is used for RDP (Remote Desktop Protocol), not web traffic.
- D. Port 21 is used for FTP (File Transfer Protocol), not secure web traffic.
HTTPS Port
HTTPS (Hypertext Transfer Protocol Secure) is the secure version of HTTP, which uses SSL/TLS for encrypted communication over TCP port 443.
- Encrypts web traffic
- Requires SSL/TLS certificates
- Standard port is 443
Memory trick: Ports are like doors, each leading to a specific server service!
