Which statement is true concerning SNATs using automap?

• Only specified self-IP addresses are used as automap addresses.
• SNATs using automap will translate all client addresses to an automap address.
• A SNAT using automap will preferentially use a floating self-IP over a non-floating self-IP.
• A SNAT using automap can be used to translate the source address of all outgoing traffic to the same address regardless of which VLAN the traffic is sent through.

Explanation

The following statement is true concerning SNATs using automap:

A SNAT using automap can be used to translate the source address of all outgoing traffic to the same address regardless of which VLAN the traffic is sent through.

When a SNAT is configured with an automap address, the BIG-IP system automatically selects an unused self-IP address from the VLAN associated with the traffic’s source address. The automap address is then used as the source IP address in the translated packet. This ensures that all traffic leaving the BIG-IP system appears to be coming from the same source IP address, regardless of which VLAN it is sent through.

Therefore, the correct option is:

• A SNAT using automap can be used to translate the source address of all outgoing traffic to the same address regardless of which VLAN the traffic is sent through.
