GNFA practice questions - frequently asked questions

Plain answers about how GNFA Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real GNFA exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The GNFA exam spans 8 domains: Common Network Protocols; Encryption and Encoding; NetFlow Analysis and Attack Visualization; Network Architecture; Network Protocol Reverse Engineering; Open Source Network Security Proxies; Security Event and Incident Logging; Wireless Network Analysis. Every practice question on this site is tagged to one of these domains.

The GNFA exam has 66 questions and is completed in 3 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
