Which mechanism allows an organization to manage a secure network environment by selecting the appropriate security levels for different zones?

• A. Intranet Zone
• B. Network Security Zoning
• C. Internet DMZ
• D. Internet Zone

Answer: (B)

Dividing the network into zones with different trust levels and applying tailored controls to each zone is the fundamental approach here. Network security zoning lets you create separate areas—like internal networks, a perimeter/DMZ, and other segments—and assign appropriate security requirements to each. By enforcing policies between zones (firewalls, access controls, monitoring) you can limit what can move from one zone to another, contain breaches, and harden the most sensitive areas. That’s why this mechanism is the best fit: it explicitly describes managing a secure environment by selecting security levels for different zones and enforcing the corresponding controls. The other options refer to specific zones or a single segment rather than the overarching strategy of organizing the network into multiple zones with distinct security levels.
