E.
8080
Suggested answer: C

Explanation:

HTTPS (Secure Web Traffic):Port 443 is the standard port for HTTPS, which is essential for encrypting communication between web browsers and a secure website. (CompTIA Server+ Objectives SK0-004: 4.1)

Why other options are not essential:

25 (SMTP):Used for email transmission

53 (DNS):Used for domain name resolution

**3389 (RDP): ** Used for remote desktop connections

**8080 (Alternate HTTP): ** Sometimes used for web servers, but not the standard secure port
