350-701 Practice Question: Which security concept involves creating multiple…
Which security concept involves creating multiple layers of defense so that if one layer is breached, subsequent layers still provide protection?
⚠ Common exam trap
Cisco often tests the distinction between Defense in depth and Zero Trust by presenting a scenario where multiple security controls are used, and candidates mistakenly choose Zero Trust because they associate 'multiple layers' with 'never trust, always verify,' but Zero Trust is about identity verification and micro-segmentation, not the layered stacking of independent defenses.

Correct answer & explanation
✓
Defense in depth
Defense in depth is a security architecture strategy that layers independent defensive mechanisms (e.g., firewalls, IDS/IPS, endpoint protection, encryption) so that if one layer is compromised, subsequent layers continue to protect the asset. This concept is fundamental to the 350-701 exam as it underpins Cisco's SecureX and integrated security fabric approach, where multiple controls (like ASA, Firepower, and Umbrella) work together to provide resilience against breaches.
