Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disabling all firewall rules for testing purposes.
Why it's wrong here
This removes security controls, the opposite of defense-in-depth.
- ✗
Storing all application data in a single encrypted volume.
Why it's wrong here
This relies on one layer of security.
- ✓
Implementing input validation, parameterized queries, and a Web Application Firewall (WAF).
Why this is correct
This provides multiple, independent layers of security against injection attacks.
- ✗
Removing all logs to prevent unauthorized access to audit trails.
Why it's wrong here
Removing logs hinders security monitoring.
- ✗
Using a single strong password for all database accounts.
Why it's wrong here
A single point of failure is bad security practice.
