JNCIA-SEC: Juniper Networks Certified Associate – Security — Question 32

By default, revenue interfaces are placed into which system-defined security zone on an SRX Series device?

Answer options

• A. junos-trust
• B. untrust
• C. trust
• D. null

Correct answer: D

Explanation

The correct answer is D, as revenue interfaces are designed to operate in the null security zone by default, which means they do not have any security policies applied to them. The other options, such as junos-trust, untrust, and trust, are predefined security zones that have specific roles and policies, making them unsuitable for revenue interfaces by default.
