• Reconnaissance: Gather open-source intelligence and passive information about target networks. You must identify data sources, extract useful details, and document findings without triggering alerts.
• Scanning and Host Discovery: Execute network scans to locate active hosts and map services. Candidates should understand ping sweeps, port scanning techniques, and how to interpret scan results to build an accurate network inventory.
• Vulnerability Scanning: Deploy automated tools to detect known weaknesses. You need to configure scanners, interpret reports, prioritize findings by severity, and distinguish false positives from genuine risks.
• Penetration Test Planning: Design a testing scope, timeline, and methodology aligned with client objectives. This includes defining rules of engagement, identifying out-of-scope systems, and planning for safe execution.
• Exploitation Fundamentals: Understand core exploitation principles and how vulnerabilities translate into system compromise. You should recognize attack chains and know when and how to move from discovery to active testing.
• Escalation and Exploitation: Execute techniques to gain higher privileges and deeper access. Candidates must identify privilege escalation vectors and apply them methodically within the test scope.
• Password Attacks: Conduct dictionary, brute-force, and hybrid password attacks. You need to select appropriate wordlists, tune attack parameters, and know when each method is practical.
• Password Formats and Hashes: Identify hash types, understand storage mechanisms, and recognize weaknesses in password implementations. This includes distinguishing salted hashes, bcrypt, NTLM, and other formats.
• Attacking Password Hashes: Apply cracking tools and techniques to recover plaintext passwords from hashes. You should optimize cracking strategies and interpret results to assess password strength.
• Advanced Password Attacks: Execute sophisticated attacks such as pass-the-hash, credential stuffing, and targeted attacks against high-value accounts. Candidates must understand when these techniques apply and how to deploy them safely.
• Kerberos Attacks: Exploit Kerberos authentication weaknesses in Windows domains. You need to recognize Kerberoasting, Golden Ticket attacks, and other domain-level compromise techniques.
• Domain Escalation and Persistence Attacks: Establish long-term access and move laterally within Active Directory environments. This includes creating backdoors, maintaining access, and covering tracks appropriately.
• Azure Overview, Attacks, and AD Integration: Understand cloud identity architecture and Azure-specific attack surfaces. Candidates should recognize how on-premises AD integrates with Azure and identify cloud-native vulnerabilities.
• Azure Applications and Attack Strategies: Target applications and services running in Azure. You need to assess cloud application security posture and apply techniques specific to cloud environments.
• Metasploit: Use the Metasploit framework to automate exploitation and payload delivery. Candidates must navigate the framework, select appropriate modules, and customize payloads for target systems.
• Moving Files with Exploits: Transfer tools, payloads, and data across compromised systems. You should understand file transfer methods, evade detection, and maintain operational security during transfers.
• Penetration Testing with PowerShell and the Windows Command Line: Leverage native Windows tools for reconnaissance, lateral movement, and persistence. Candidates must write and execute PowerShell scripts, use command-line utilities, and understand Windows internals.

Question Formats & What They Test

The GPEN exam uses multiple-choice and scenario-based questions to measure both foundational knowledge and applied decision-making. Questions progress in difficulty and require you to think through real penetration testing situations.

• Multiple Choice: Test core definitions, tool functionality, attack mechanics, and key terminology. These questions confirm you understand the "what" and "how" of penetration testing techniques.
• Scenario-Based Items: Present realistic testing situations and ask you to choose the best next step, tool, or approach. You may be asked to interpret scan results, decide whether to escalate privileges, or select a password attack method based on given constraints.
• Practical Reasoning: Require you to connect topics across reconnaissance, exploitation, and post-compromise phases. Questions may ask how reconnaissance findings inform exploitation planning or how to maintain persistence without disrupting business operations.

Questions are designed to reflect real penetration testing workflows, so studying with practical scenarios and hands-on labs strengthens your ability to answer confidently.

Preparation Guidance

Effective preparation maps the 17 core topics to a structured study schedule, balances theory with hands-on practice, and includes regular self-assessment. A typical approach spans 8-12 weeks, with deeper focus on high-weight topics like exploitation, password attacks, and post-compromise techniques.

• Organize study into weekly blocks: dedicate Week 1-2 to reconnaissance and scanning, Week 3-4 to vulnerability assessment and planning, Week 5-7 to exploitation and privilege escalation, and Week 8-10 to password attacks, Kerberos, and domain persistence. Week 11-12 should focus on Azure, PowerShell, and weak areas.
• Work through practice question sets after each topic block. Review explanations for both correct and incorrect answers to understand the reasoning behind each choice.
• Connect concepts across the penetration testing lifecycle: understand how reconnaissance informs scanning, how scanning feeds vulnerability assessment, and how vulnerabilities guide exploitation planning.
• Set up a lab environment (virtual machines or cloud instances) to practice reconnaissance tools, run vulnerability scans, execute exploits, and test post-compromise techniques in a safe space.
• Conduct a timed practice test under exam conditions (usually 3 hours) at least one week before your exam date. Use results to identify remaining weak spots and adjust your final review.
• In the final week, review high-risk topics, redo challenging practice questions, and ensure you understand the "why" behind each answer.

Frequently Asked Questions

What topics carry the most weight on the GPEN exam?

Exploitation, privilege escalation, and post-compromise techniques (including password attacks, Kerberos attacks, and domain persistence) typically account for the largest portion of the exam. Reconnaissance and scanning are foundational but usually represent fewer questions. Focus study time proportionally: spend more on exploitation workflows and less on basic tool usage, though both matter.

How do reconnaissance and scanning connect to exploitation planning?

Reconnaissance and scanning provide the intelligence that guides exploitation decisions. Findings from these phases inform which systems to target, what services are running, and which vulnerabilities are exploitable. During the exam, you may be asked to interpret scan results and decide which vulnerability to pursue first based on risk, access level, or business impact. Understanding this workflow helps you answer scenario questions correctly.

How much hands-on lab experience is needed to pass GPEN?

Hands-on experience is valuable but not strictly required if you study effectively. However, candidates who have set up labs, run Metasploit, executed password attacks, and practiced privilege escalation typically score higher and feel more confident. Prioritize labs for exploitation, password attacks, and Kerberos techniques since these topics have high exam weight and benefit most from practical exposure.

What common mistakes lead to lost points on GPEN?

Common errors include misidentifying hash types or attack prerequisites, choosing a tool before understanding the target environment, and failing to consider operational security or scope boundaries. Many candidates also underestimate the importance of planning and jump straight to exploitation. Scenario questions often reward methodical thinking over speed, so read carefully and consider the full context before selecting an answer.

How should I approach the final week before the GPEN exam?

Use your final week to review weak topics, redo difficult practice questions, and take a full-length timed practice test. Avoid learning new material; instead, reinforce concepts you already understand. The night before the exam, review key terminology and attack prerequisites (e.g., hash types, Kerberos attack conditions) rather than attempting new labs. Ensure you are well-rested and familiar with the exam format and time limit.
