Which deployment mode in SonicWall allows for seamless integration with an existing network without changing IP addressing?

The correct choice is Transparent mode because it enables the SonicWall firewall to integrate seamlessly into an existing network without requiring any changes to the current IP addressing scheme. This mode effectively allows the firewall to sit between two network segments and inspect traffic while acting like a bridge, instead of functioning as a traditional router.

In Transparent mode, the firewall uses a single IP address for management while allowing traffic to flow through without altering the IP packets. This means that devices on both sides can communicate without needing to be aware of the firewall’s presence. Only the management interface requires an IP address, which simplifies deployment in environments where changes to IP addressing might create disruptions.

Layer 2 Bridge mode, while similar in allowing the firewall to act like a bridge, usually involves more complex configurations that can sometimes necessitate adjustments in IP addressing when connecting different segments. Router mode, on the other hand, typically requires that IP addresses be reconfigured since it changes the routing topology of the network. Access Point mode specializes in wireless configurations and does not pertain to the broader networking implications that Transparent mode addresses.
