- Network security basics: authentication, encryption, segmentation and common attack surfaces.
Common exam traps
- Confusing DNS with HTTP.
- Treating a switch as a router.
- Mixing transport-layer reliability with application-layer responsibilities.
- Memorizing ports without understanding the protocol.

Quick check
Quick check: Which protocol is used to translate a domain name such as example.com into an IP address?
- A. HTTP
- B. DNS
- C. SSH
- D. SMTP
Answer: DNS
Why: The Domain Name System resolves domain names to IP addresses so applications can connect to the correct host.
