The correct sequence of actions for configuring a multi-instance environment for high availability on a Cisco Firepower 4100 appliance is as follows:

Add a resource profile for container instances. A resource profile defines the CPU, RAM, and disk space allocation for each container instance.You can create multiple resource profiles with different resource settings and assign them to different container instances1.

Add a MAC pool prefix and view the MAC address for the container instance interfaces. A MAC pool prefix is a 24-bit prefix that is used to generate MAC addresses for the container instance interfaces. You can specify a custom MAC pool prefix or use the default one.You can also view the MAC addresses that are assigned to each container instance interface1.

Configure interfaces. You need to configure the physical interfaces, EtherChannels, and VLAN subinterfaces that will be used by the container instances.You can also configure shared interfaces that can be used by multiple container instances on the same security module/engine1.

Add a Standalone Firepower Threat Defense for Cisco Secure Firewall Management Center. You need to add a logical device that runs a standalone Firepower ThreatDefense (FTD) application instance and register it with the Cisco Secure Firewall Management Center (FMC).This logical device will act as the management interface for the container instances1.

Add a high-availability pair. You need to add another logical device that runs a standalone FTD application instance and register it with the FMC as well. Then, you need to configure high availability (HA) between the two standalone FTD logical devices.This will enable HA for the container instances that are associated with them1.

The content keyword is used to specify a string or pattern to search for in the payload or stream of a packet. The string must be enclosed in quotation marks and can use modifiers such as nocase, depth, offset, and so on. The string can also use hexadecimal notation by using a pipe symbol (|) before and after the hexadecimal characters. For example, content:"|45 5* 26 27 4 0A|" will match any payload or stream that contains the hexadecimal bytes 45 5 26 27 4 0A followed by any number of bytes2

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.
