An engineer is configuring a custom application detector for HTTP traffic and wants to import a file that was provided by a third party. Which type of flies are advanced application detectors creates and uploaded as?

Show Suggested Answer Hide Answer
Suggested Answer: C

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.

I agree, it's all about NBAR for HTTP traffic.

Perl scripts sound familiar, but I thought they were more for older systems. Could it be LUA instead?

I feel like Python programs are common for these types of applications, but I can't recall if that's specifically for detectors.

I remember practicing a question about NBAR protocols, but I don't think that's what we're looking for here.

LUA scripts, that's the answer. I remember learning about that in the course material.

This is a tricky one. I'm not super familiar with the specific details of subscription contracts in SAP S/4HANA Service, so I'm not 100% sure which line item would be part of the contract after a change process. I'll have to review my notes and try to reason through the options.

Okay, I think I have a plan. I'll focus on options that limit the initial scope, like designing for a single dimension or a single target and source.

That's a good point. LUA scripts are often used for network-related tasks. But Python is also a popular language for security and networking tools. Maybe D) Python program is the correct answer?

Okay, let's think this through. An engineer is configuring a custom application detector for HTTP traffic, so it's probably a scripting language of some kind. I'm going to guess C) LUA script, since that's a common language used for network and security applications.

Yeah, I agree. This is definitely not a straightforward question. I'm guessing it has something to do with the file format used for these custom application detectors.
