Question

An engineer must implement Cisco Secure Firewall transparent mode due to a new server recently being added that must communicate with an existing server that is currently separated by the firewall. Which implementation action must be taken next by the engineer to accomplish the goal?

Options

  • AConfigure the same default gateway for both servers.
  • BEnsure that both servers are in the same bridge domain.
  • CEnable both servers to share the same VXLAN segment.
  • DAssign the same subnet to both servers.

Explanation

In transparent mode, Cisco Secure Firewall Threat Defense (FTD) operates as a Layer 2 firewall, acting as a "bump in the wire" without performing routing functions. This mode allows devices on either side of the firewall to communicate as if they were on the same network. To achieve this, the firewall typically uses bridge domains or similar configurations to group devices. A bridge domain groups interfaces in transparent mode so that devices on each side of the firewall can communicate directly. Ensuring that both servers are in the same bridge domain allows traffic to pass through the firewall transparently, enabling communication between the two servers as if the firewall were not there.
