Correct Answer: C
The output shown in the exhibit is from the command "show security flow session family inet6". This command displays the IPv6 flow sessions on the SRX Series device. The output shows that there are two total sessions, both of which are valid. This means that the SRX Series device is configured with flow-based IPv6 forwarding options. Flow-based IPv6 forwarding options enable the device to process IPv6 packets using the security policies, NAT, and other security features. To configure flow-based IPv6 forwarding options, use the command set security forwarding-options family inet6 mode flow-based and reboot the device. Reference:
