If a task to generate troubleshooting files in Cisco Secure Firewall Management Center (FMC) is completed successfully but removed before the files are downloaded, the following steps can be taken to determine the filename and obtain the generated troubleshooting files without regenerating them:

Go to expert mode on Secure FMC:

Access expert mode on the FMC via SSH or the console.

List the contents of the directory/var/commonto locate the generated troubleshooting files. Use the commandls /var/common.

Use the System Monitoring Audit logs:

In FMC, navigate toSystem > Monitoring > Audit.

Find the line containing the "Generate Troubleshooting Files" string to determine the correct filename.

These actions help identify and retrieve the generated troubleshooting files without the need to regenerate them, saving time and resources.

To exempt a custom application from being flagged by Cisco Secure Endpoint, the organization must precalculate the hash value of the custom application and add it to the allowed applications list. This process involves creating a hash of the executable file, which uniquely identifies it, and then configuring Cisco Secure Endpoint to recognize this hash as trusted.

Steps:

Calculate the hash value (e.g., SHA-256) of the custom application executable.

In the Cisco Secure Endpoint management console, navigate to the policy configuration.

Add the calculated hash value to the list of allowed applications or exclusions.

Save and deploy the updated policy.

By adding the hash value to the allowed applications, Cisco Secure Endpoint will recognize the custom application as trusted and will no longer flag it.

When replacing a Cisco Secure Firewall high-availability (HA) device due to a failure, the first step the engineer must take is to unregister the secondary (failed) device from the Cisco Secure Firewall Management Center (FMC). This action separates the HA pair and ensures that the new replacement device can be registered and configured correctly.

Steps:

Access the FMC and navigate to the device management section.

Unregister the failed secondary device to remove it from the HA pair.

Register the replacement device to the FMC.

Reconfigure the HA settings to restore the high-availability configuration.

By unregistering the failed device first, the engineer ensures a clean setup for the replacement device, avoiding potential conflicts or issues in the HA configuration.

To add a Cisco Secure Firewall Threat Defense (FTD) device to Cisco Secure Firewall Management Center (FMC), the correct command to use isconfigure manager add 192.168.75.201 . This command registers the FTD device with the FMC using the FMC's IP address and the registration key provided during the FMC setup.

Command structure:

configure manager add

For the given scenario:

FMC IP address: 192.168.75.201

Registration key: provided during FMC setup

Thus, the correct command is:

configure manager add 192.168.75.201

A custom application detector is a user-defined script that can detect web applications, clients, and application protocols based on patterns in network traffic. Custom application detectors are written in LUA, which is a lightweight and embeddable scripting language. LUA scripts can use predefined functions and variables provided by the Firepower System to access packet data and metadata, and to specify the detection criteria and the application information1.

To import a custom application detector file that was provided by a third party, you need to follow these steps1:

In the FMC web interface, navigate to Objects > Object Management > Application Detectors.

Click Import.

Browse to the location of the LUA script file and select it.

Click Upload.

Review the detector details and click Save.

The other options are incorrect because:

Perl script is not a supported format for custom application detectors. Perl is a general-purpose programming language that is not embedded in the Firepower System.

NBAR protocol is not a file type, but a feature of Cisco IOS routers that can classify and monitor network traffic based on application types. NBAR protocols are predefined and cannot be imported as custom application detectors.

Python program is not a supported format for custom application detectors. Python is a general-purpose programming language that is not embedded in the Firepower System.
