You have implemented a tunnel in your network using DS-Lite. The tunnel is formed
between one of the SRX devices in your network and a DS-Lite-compatible CPE device in
your customer’s network. Which two statements are true about this scenario? (Choose two.)
A.
The SRX device will serve as the softwire concentrator and the customer CPE device will
serve as the softwire initiator.
B.
The infrastructure network supporting the tunnel will be based on IPv4.
C.
The SRX device will serve as the softwire initiator and the customer CPE device will
serve as the softwire concentrator.
D.
The infrastructure network supporting the tunnel will be based on IPv6.
Correct: A and D

In that page we can see the info :
” Solution:
SRX firewalls support only the Software Concentrator.”
That’s why question A …. customer CPE device will serve as the softwire initiator.
SRX is always the “softwire concentrator”; the other end CPE is “softwire initiator”.
A & D are correct answer.
