Which term best describes a defense strategy that stacks multiple protective layers on endpoints?

• A. Contextual Detections
• B. Layered Protection
• C. Zero-Day Attacks
• D. APTs

Answer: (B)

The idea being tested is how a defense strategy stacks multiple protective layers on endpoints. Layered Protection describes using several independent security measures to protect endpoints, so if one layer is bypassed, others still block or detect the threat. This approach is effective because each layer addresses different attack vectors and failure modes, providing multiple barriers that collectively strengthen security. Examples include combining capability like antivirus, firewall, application control, endpoint detection and response, and patch management. That combination is what the term Layered Protection conveys: multiple layers working together to harden endpoints. The other terms refer to concepts that aren’t about a multi-layer defense strategy: contextual detections describe detection methods based on context rather than stacking defenses; zero-day attacks are a type of exploit; APTs are sophisticated threat actors.
