What does micro-segmentation imply in a Zero Trust model?

• A. Granular access controls between workloads
• B. Global trust for all internal traffic
• C. No segmentation
• D. Reliance on a single perimeter

Answer: (A)

In Zero Trust thinking, micro-segmentation means dividing the network into very small, secure zones around individual workloads or services and enforcing access policies for traffic between them. This provides granular control over how each workload talks to others, so even if an attacker gets inside, movement is limited because every interaction must meet specific permissions. It’s the opposite of trusting all internal traffic, having no segmentation, or relying on a single perimeter.
