Which two statements are true about SNATs. (Choose two.)
The correct answer is A. SNATs are enabled on all VLANs, by default. C. SNATs can be configured within a Virtual Server definition.. On F5 BIG-IP, SNATs apply to all VLANs by default and can be configured directly within a virtual server definition to enable source address translation for that virtual server's traffic.

Why each option
On F5 BIG-IP, SNATs apply to all VLANs by default and can be configured directly within a virtual server definition to enable source address translation for that virtual server's traffic.
When a SNAT is created on BIG-IP without specifying VLAN restrictions, it is enabled on all VLANs by default, making it applicable to traffic on any interface unless the administrator explicitly limits its scope.
SNATs are independent objects on F5 BIG-IP and are not configured within Profile definitions; profiles govern connection behavior, protocol handling, and persistence, not address translation.
F5 BIG-IP allows a SNAT pool or automap SNAT to be specified directly in the virtual server configuration, giving administrators a way to apply source address translation specifically to traffic handled by that virtual server.
SNATs are enabled on all VLANs by default, not restricted to only the VLAN where origin traffic arrives; VLAN restriction requires explicit administrator configuration.
