Why each option
An interface on a firewall can belong to only one security zone at a time to ensure clear network segmentation and consistent application of security policies.
Assigning an interface to a single security zone simplifies security policy design, prevents ambiguity in traffic classification, and ensures predictable rule application, maintaining clear network boundaries.
Allowing an interface to belong to multiple zones would complicate policy evaluation and could lead to security vulnerabilities due to unclear zone boundaries and conflicting policy applications.
