Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Geo-blocking
Why it's wrong here
Geo-blocking restricts access by location.
- ✗
Rate limiting
Why it's wrong here
Rate limiting controls traffic volume, not injection attacks.
- ✓
OWASP rule set
Why this is correct
OWASP rules include SQL injection detection/prevention.
- ✗
DDoS protection
Why it's wrong here
DDoS protection mitigates volumetric attacks that flood bandwidth or exhaust server resources, but it does not inspect HTTP request payloads for malicious SQL syntax, which is the specific vector in SQL injection. It is tempting because a WAF commonly bundles DDoS mitigation alongside application-layer filtering, and in a scenario where availability is threatened by a flood attack, enabling DDoS protection would be the correct choice.
