JNCIP-SEC: Juniper Networks Certified Professional – Security (2024) — Question 56

Which two statements about transparent mode and Ethernet switching mode on an SRX Series device are correct? (Choose two.)

Answer options

• A. In transparent mode, IRB Interfaces must be placed in a security zone
• B. In Ethernet switching mode Layer 2 Interfaces must be placed in a security zone.
• C. In transparent mode, Layer 2 interfaces must be placed in a security zone.
• D. In Ethernet switching mode. IRB Interfaces must be placed in a security zone.

Correct answer: C, D

Explanation

In transparent mode, Layer 2 interfaces must indeed be placed in a security zone, which makes option C correct. Additionally, Ethernet switching mode requires IRB interfaces to be assigned to a security zone, validating option D. Options A and B are incorrect because they misrepresent the requirements for IRB and Layer 2 interfaces in their respective modes.
