Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Why this is correct
WAF specifically inspects HTTP/HTTPS traffic and blocks OWASP Top 10 attacks.
- ✗

Why it's wrong here
Whitelisting controls execution, not network-level injection.
