Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A strict perimeter firewall without internal controls.
Why it's wrong here
This relies on a single layer and fails to protect against threats inside the network.
- ✗
Encryption at rest only.
Why it's wrong here
This addresses only one aspect of data protection, not multiple layers.
- ✓
A firewall, intrusion detection system, and regular security awareness training.
Why this is correct
This combines technical, physical, and administrative controls at multiple layers, which is defense in depth.
- ✗
A single strong password policy.
Why it's wrong here
This is a single control, not a layered defense.
