ExploreAbout this exam
CyberSec First Responder® – Advanced (CFR-A) is an advanced, hands-on cybersecurity credential from CertNexus. It builds on the defensive skills covered in CyberSec First Responder® (CFR) and is aimed at practitioners in red-team, blue-team, or hybrid roles who want to validate advanced knowledge of attack simulation, threat analysis, security testing, digital forensics, and cyber defense techniques. The credential is organized around three applied modes: Attack, Analyze, and Address. Attack means simulating attacks to test security measures and understand threat vectors; Analyze means detecting and assessing threats to understand how attacks operate and affect security; Address means implementing countermeasures and protections to reduce the impact of cyber threats. The CFA-110 assessment contains 25 multiple-choice and multiple-response items, and the passing score is 80%, or 20 out of 25 items. It is delivered online through the CHOICE platform, and candidates may retake it as many times as desired. Preparation should start with the official CFA-110 exam blueprint. Candidates can also use CFR-A credential-aligned training from CertNexus Authorized Training Partners and focus on threat detection, security monitoring, incident response, network defense, vulnerability assessment, digital forensics concepts, recovery, reporting, and post-incident improvement. Recommended prerequisites include having taken and passed the CFR-410 exam, intermediate Linux skills, command-line experience, familiarity with tools such as Nmap and Metasploit, incident response knowledge, and some programming or scripting familiarity.
What you'll study
About CFR-410 preparation
What is the CFR-A exam format?
The CFA-110 assessment has 25 items in multiple-choice and multiple-response formats. It is delivered online through the CHOICE platform. The passing score is 80%, or 20 out of 25 items. The exam duration is estimated at 20-45 minutes.
How difficult is the CFR-A exam?
CFR-A is an advanced, hands-on credential. It assumes defensive knowledge from CFR and expects familiarity with intermediate Linux, the command line, Nmap, Metasploit, incident response, and some scripting. The 80% passing score (20/25) leaves little room for error, so hands-on practice matters.
Can I retake the CFR-A assessment?
Yes. Candidates may retake the assessment as many times as desired. There is no stated limit or waiting period. Use each attempt to identify weak domains, especially if you are near the 20/25 threshold.
How long is the CFR-A exam?
The exam duration is estimated at 20-45 minutes for 25 items. That is roughly one to two minutes per question. Multiple-response items may take longer, so pace yourself and flag time-consuming questions.
What should I study first for CFR-A?
Start with the official CFA-110 exam blueprint to identify the domains and objectives. Then reinforce attack simulation, threat analysis, and protections. Hands-on work with tools such as Nmap and Metasploit, log analysis, active monitoring, and digital forensics concepts is more useful than memorizing definitions.
What are the recommended prerequisites for CFR-A?
CertNexus recommends having taken CyberSec First Responder® (CFR-410) and passed the associated exam. The CFR-A outline also recommends intermediate Linux skills, command-line experience, familiarity with tools such as Nmap and Metasploit, incident response knowledge, and some programming or scripting familiarity.
What topics does the CFR-A exam cover?
CFR-A focuses on three applied modes: Attack, Analyze, and Address. Topics include reconnaissance, vulnerability exploitation, Metasploit, web application vulnerabilities, log analysis, active monitoring, digital forensics, and implementing protections for data, access, software, networks, and systems.
Why do candidates fail CFR-A?
Common failure modes include underestimating hands-on tool knowledge, weak Linux and command-line skills, and neglecting the Address domain because they focus only on offensive techniques. With 20/25 needed to pass, missing a few multiple-response items can be decisive. Review the blueprint and practice each mode.
Is CFR-A the same as CFR?
No. CFR-A builds on the defensive skills and knowledge covered in CyberSec First Responder® (CFR). It is intended for learners who have completed CFR and want to go deeper into hands-on methods and tactics used to defend against a range of cyber threats.
