Which two statements are true regarding NAT64? (Choose two.)
The correct answer is A. An SRX Series device should be in flow-based forwarding mode for IPv4. D. An SRX Series device should be in flow-based forwarding mode for IPv6. NAT64 is a mechanism that allows IPv6-only clients to communicate with IPv4-only servers. On Juniper SRX Series devices, NAT64 is implemented using the flow-based mode, not packet- SRX devices operate in two modes: flow-based (default for branch/enterprise use) and packet…

Explanation
NAT64 is a mechanism that allows IPv6-only clients to communicate with IPv4-only servers. On Juniper SRX Series devices, NAT64 is implemented using the flow-based mode, not packet- SRX devices operate in two modes: flow-based (default for branch/enterprise use) and packet- based (used in some special scenarios). NAT64 requires the deep inspection and session management features provided by flow mode.
