NSE4 · Question #301
A FortiGate interface is configured with the following commands: What statements about the configuration are correct? (Choose two.)
The correct answer is A. IPv6 clients connected to port1 can use SLAAC to generate their IPv6 addresses. C. FortiGate can send IPv6 router advertisements (RAs.). The FortiGate interface configuration enables IPv6 Router Advertisements (RAs) and stateless DHCPv6 on port1.

Why each option
The FortiGate interface configuration enables IPv6 Router Advertisements (RAs) and stateless DHCPv6 on port1.
The `ipv6sendra enable` command allows IPv6 clients connected to port1 to use Stateless Address Autoconfiguration (SLAAC) to generate their IPv6 addresses based on the advertised prefix.
While `ipv6dhcp6-mode stateless` allows the FortiGate to provide DNS settings via DHCPv6, the provided configuration snippet does not explicitly show DNS servers being configured to be advertised.
The `ipv6sendra enable` command explicitly configures the FortiGate to send IPv6 Router Advertisements on the port1 interface.
The `ipv6dhcp6-mode stateless` setting indicates that the FortiGate provides configuration information but does not assign IPv6 addresses; address assignment is typically handled by SLAAC in this mode.
Concept tested: FortiGate IPv6 interface configuration (SLAAC, RAs, DHCPv6)
