JNCIP-SEC: Juniper Networks Certified Professional – Security (2024) — Question 69

Which role does an SRX Series device play in a DS-Lite deployment?

Answer options

• A. softwire concentrator
• B. softwire initiator
• C. STUN client
• D. STUN server

Correct answer: A

Explanation

The correct answer is A, as the SRX Series device acts as a softwire concentrator, managing the encapsulation of IPv4 packets within IPv6. Options B, C, and D are incorrect because a softwire initiator establishes the connection, and STUN client and server roles are related to NAT traversal, not the primary function of the SRX in DS-Lite.
