Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implementing network segmentation to restrict lateral movement between departments
Defense in depth relies on layering independent security controls, such as network segmentation and multi-factor authentication, so that if one control fails, another provides protection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Relying entirely on a single powerful perimeter firewall with no internal security controls
Why it's wrong here
A single perimeter approach violates defense in depth; once breached, the internal network is completely open.
- ✓
Implementing network segmentation to restrict lateral movement between departments
Why this is correct
Segmentation stops an attacker from moving freely across the entire internal network.
- ✓
Requiring multi-factor authentication for all remote and privileged user access
Why this is correct
MFA adds an essential second layer of defense against compromised credentials.
- ✗
Eliminating all system logs and monitoring to maximize user privacy
Why it's wrong here
Removing logs prevents incident detection and forensic investigation.
- ✗
Disabling all endpoint antivirus solutions to improve computer processing speed
Why it's wrong here
Disabling endpoint protection removes a critical layer of defense against malware.
