The capture should be taken on the DMZ interface of the perimeter firewall because this is the firewall interface closest to the affected server. Capturing there shows the packets delivered to the server and the TCP RST packets returned by it. This placement helps determine whether the reset originates from the server, whether address translation changed the connection, or whether the firewall generated or altered the traffic. Capturing only on the internet-facing interface would show the external behavior but provide less certainty about what reached or left the DMZ server. The perimeter router and ISP router are even farther from the suspected source. Cisco troubleshooting guidance recommends capturing as close as possible to the relevant endpoint and on the associated firewall data interface. List B’s supplied answer C is therefore incorrect and has been corrected to D. Cisco firewall capture analysis

To configure Active Directory authentication for VPN authentication on a Cisco Secure Firewall Threat Defense (FTD) instance registered with Cisco Secure Firewall Management Center (FMC), the administrator needs to configure Realms in the System settings of the FMC. Realms in FMC are used to define the directory servers (e.g., Active Directory) and how they are used for user authentication.

Steps to configure this in FMC:

Navigate toSystem > Integration > Realms and Directory.

Add a new realm and configure the necessary details such as the directory server type (e.g., Active Directory), server address, and bind credentials.

Test the connection to ensure it works correctly.

This setup allows the FMC to authenticate VPN users against the Active Directory, thereby enabling secure access control for VPN connections.

In Cisco Secure Firewall Management Center (FMC), when two users attempt to modify a VPN policy simultaneously, the system implements a locking mechanism to prevent conflicts. The first user who selects edit on the policy locks the configuration, preventing other users from making changes until the lock is released.

Steps:

When the first user selects edit on the VPN policy, FMC locks the policy for editing.

The lock ensures that only the first user can make changes.

Once the first user saves or cancels their changes, the lock is released.

Other users can then edit the policy.

This locking mechanism ensures that configuration conflicts are avoided and only one set of changes is applied at a time.
