Transparent firewall mode forwards traffic at Layer 2, so the participating physical interfaces must be assigned to at least one bridge group. This allows the device to inspect traffic while remaining logically transparent to the connected switch stacks. Bridge Protocol Data Units should also be exempted from advanced inspection. BPDUs are essential for spanning-tree operation, and delaying or blocking them during inspection restarts can produce topology instability or an interruption. A BVI provides Layer 3 addressing for device-originated traffic or management but is not inherently required merely to inspect transit traffic. Jumbo-frame configuration is unnecessary unless the network explicitly uses jumbo frames, and separate data and management routes do not establish transparent forwarding. Cisco specifically recommends using an EtherType ACL to trust BPDUs on each bridge-group member interface. Cisco transparent firewall configuration

To allow access to a specific banking site over HTTPS, the network administrator must use SSL decryption (also known as SSL/TLS inspection) and specify the URL. This is because HTTPS traffic is encrypted, and the firewall needs to decrypt the traffic to inspect the URL and enforce the access rule.

Steps:

Enable SSL Decryption: Configure SSL policies to decrypt the HTTPS traffic.

Specify the URL: Define the URL of the banking site in the access control policy, ensuring that the decrypted traffic is inspected and allowed based on the specified URL.

This method ensures that only the desired banking site is accessed over HTTPS, while other HTTPS traffic can be filtered or blocked according to the organization ' s security policies.

Traditionally, a firewall is a routed hop and acts as a default gateway for hosts that connect to one of its screened subnets. A transparent firewall, on the other hand, is a Layer 2 firewall that acts like a “bump in the wire,” or a “stealth firewall,” and is not seen as a router hop to connected devices. However, like any other firewall, access control between interfaces is controlled, and all of the usual firewall checks are in place. Layer 2 connectivity is achieved by using a " bridge group " where you group together the inside and outside interfaces for a network, and the ASA uses bridging techniques to pass traffic between the interfaces. Each bridge group includes a Bridge Virtual Interface (BVI) to which you assign an IP address on the network. You can have multiple bridge groups for multiple networks. In transparent mode, these bridge groups cannot communicate with each other.https://www.cisco.com/c/en/us/td/docs/security/asa/asa97/configuration/general/asa-97-general-config/intro-fw.html

To configure URL filtering for a Cisco FTD device in Cisco FMC, and to meet the requirements of the question, the engineer must do the following:

On the HTTP Responses tab of the access control policy editor, set the Interactive Block Response Page to system-provided. This will enable the system to display a warning page to the users when they try to access a blocked URL, and give them the option to continue or cancel. The system-provided page is a default page that contains a generic message and a logo1.

Configure an access control rule that matches an URL object for http://www.badadultsite.com; and set the action to Interactive Block. This will apply the interactive block action to the specific URL that is defined in the URL object. The interactive block action will trigger the interactive block response page that was configured in the previous step1.

The other options are incorrect because:

On the HTTP Responses tab of the access control policy editor, setting the Block Response Page to Custom will not affect the interactive block action. The block response page is used when the action is set to Block, not Interactive Block1.

Configuring the default action for the access control policy to Interactive Block will apply the interactive block action to all URLs that are not matched by any access control rule. This will not meet the requirement of blocking no other websites1.

Configuring an access control rule that matches the Adult URL category and sets the action to Interactive Block will apply the interactive block action to all URLs that belong to the Adult category. This will not meet the requirement of blocking only http://www.badadultsite.com1.

Reason: the command " capture-traffic " is used for SNORT Engine Captures. To capture a LINA Engine Capture, you use the " capture " command. Since the Lina Engine represents the actual physical interface of the device, " capture " is the only reasonable choice Reference:https://www.cisco.com/c/en/us/support/docs/security/firepower-ngfw/212474-working-with-firepower-threat-defense-f.html#anc10

The command is

firepower# capture DMZ interface dmz trace detail match ip host 192.168.76.14 host 192.168.76.100

firepower# capture INSIDE interface inside trace detail match ip host 192.168.76.14 host 192.168.75.14
