Episode 7: Example Performance-Based Questions (PBQs) Walkthrough
Welcome back to your CYSA Plus Prep cast. In Episode Seven, we’re diving deep into one of the most important and challenging elements of your exam—performance-based questions, or PBQs. Unlike standard multiple-choice formats, PBQs simulate real-world cybersecurity tasks and ask you to solve practical problems using your analytical and technical skills. In this episode, we’ll break down what PBQs are, walk through example scenarios, and guide you through proven strategies to help you approach these interactive questions with clarity and confidence.
Performance-based questions are built to test not just what you know, but what you can do. Instead of selecting answers from a list, you’ll be asked to apply your knowledge in simulated environments. You might be asked to review logs, configure devices, analyze scan reports, or walk through an incident response workflow. These questions closely mirror actual tasks you might perform in a security operations center or while working as an incident responder. That makes PBQs more demanding than multiple-choice questions—but also more reflective of your professional readiness.
Unlike traditional questions that reward memorization, PBQs require deliberate thinking and hands-on judgment. For example, you might be presented with simulated SIM output—Security Information and Event Management logs—and asked to identify signs of compromise. These logs may show repeated failed login attempts, unauthorized access, communication to external addresses, or abnormal port usage. Each of these indicators could represent an ongoing threat, and your job is to interpret them within the context provided. This format evaluates your ability to detect anomalies using real tools and data.
Let’s break down a specific example. Imagine you are presented with log files from a simulated SIM interface. You’re told a potential insider threat has been reported. Your job is to identify the relevant indicators and determine whether unauthorized data exfiltration occurred. You begin by scanning the logs for suspicious behavior. Look for multiple failed logins, access to sensitive directories, large file transfers, and connections to unfamiliar IP addresses. The key is to stay calm, filter out normal activity, and focus on high-risk patterns.
Once you spot suspicious entries, your next task is to correlate the data. Are the same user accounts involved in multiple anomalies? Is traffic leaving the network during unusual hours? Can any of the IP addresses be matched to known malicious hosts or blacklists? Matching this data with common indicators of compromise—like beaconing behavior, unexpected protocols, or known malware activity—helps build the full picture. The goal is not just to point to a suspicious log, but to piece together the story that it tells.
Another frequent type of PBQ is vulnerability analysis. In these questions, you may be shown a vulnerability scan report with CVSS scores, asset types, and system roles. Your task is to prioritize remediation steps. This involves more than just selecting the highest-scoring vulnerability. You must also consider business context. For example, a lower-severity vulnerability on a public-facing web server might be more urgent than a critical vulnerability on an isolated test machine. The exam is looking for your ability to apply judgment, not just read numbers.
To approach vulnerability prioritization PBQs, examine each entry carefully. Consider whether the asset is exposed to the internet, whether it supports a critical business function, and whether there are known exploits available. Prioritize vulnerabilities that pose the highest risk when context is factored in. This simulates real-world triage, where time and resources are limited, and decisions must be made strategically. Practicing with real vulnerability scanners and learning to read reports from tools like Nessus or OpenVAS can help tremendously here.
You may also encounter PBQs that ask you to configure or troubleshoot security tools. A typical scenario might involve setting up firewall rules based on specified policies. You’ll be asked to allow or deny certain types of traffic, define port ranges, or apply access control to specific IP addresses. These configuration tasks mirror what a junior analyst might do in a live environment, and accuracy matters. A misconfigured rule could either block legitimate traffic or leave an attack vector open.
When handling configuration-based PBQs, always start by fully understanding the security policy you’re being asked to enforce. Identify which services should be allowed, which networks should be blocked, and any exceptions that must be configured. Once you begin making changes, proceed methodically—configure one rule at a time, double-check syntax, and confirm that your setup matches the scenario requirements. Rushing through configurations without planning can easily lead to errors.
Some PBQs might also involve working with intrusion prevention systems or adjusting detection rules. These questions test your ability to translate security policies into technical controls. You may need to choose which signatures to activate, determine alert thresholds, or configure rule exceptions. Understanding how IDS and IPS tools behave in different environments will help you handle these scenarios with more ease. If you’ve used tools like Snort or Suricata in a lab, you’ll have a strong advantage.
One additional challenge of PBQs is the time investment they require. While multiple-choice questions can often be answered in under two minutes, PBQs may take significantly longer. Some questions involve multi-step analysis, complex configuration, or careful prioritization. Time management becomes essential. Allocate about ten to fifteen minutes for each PBQ. If a scenario is too complex or you find yourself getting stuck, it’s perfectly acceptable to mark it for review and return later with a fresh perspective and more time.

Another performance-based question format you may encounter involves incident response walk-throughs. These scenarios are designed to test your understanding of how to respond logically and efficiently to cybersecurity incidents. For example, you may be shown signs of a ransomware infection on multiple workstations—perhaps through suspicious registry changes, encrypted file extensions, or ransom notes—and then asked to determine the appropriate response sequence. This typically involves selecting the correct steps in order, from containment to eradication to recovery.
In such a case, you would first isolate the infected systems from the network to prevent the ransomware from spreading. Then, you would preserve forensic evidence, such as volatile memory and log files, for analysis. Next, remediation would include removing the malware, restoring systems from backups, and applying security patches. Finally, you would resume normal operations while reviewing and updating security measures to prevent recurrence. These questions don’t just assess whether you know what to do—they measure whether you know how and when to do it.
Log analysis PBQs are another frequent and important type. You may be presented with log excerpts from various systems, such as firewalls, SIMs, or endpoint protection tools. Your task could be to identify the source of a breach, the time of compromise, or the methods used by the attacker. For instance, you might see a series of login attempts, a privilege escalation, and data being sent to an external IP address. From this data, you must piece together the attack narrative and select the correct findings or actions.
When handling log-based PBQs, pay close attention to timestamps, source and destination addresses, user account names, and specific commands executed. Patterns like repeated failed login attempts, sudden privilege changes, or anomalous outbound traffic can indicate malicious behavior. Your goal is to identify these indicators while filtering out normal activity. Accuracy in this area requires a methodical eye and the ability to interpret sequences logically—both skills that are central to security analyst roles and heavily emphasized in the CYSA Plus exam.
One universal strategy for PBQs is to read every instruction carefully. Even if the task seems familiar, the question may contain specific instructions or constraints that must be followed precisely. Missing a small but important detail—such as the scope of a rule or the required order of actions—can lead to mistakes. Take your time at the start of the PBQ to fully understand what is being asked. Clarity at the beginning will save you time and confusion later in the task.
When beginning any PBQ, resist the urge to jump straight into actions. Instead, pause and clearly identify what the question is asking you to do. Determine whether the goal is analysis, configuration, prioritization, or sequencing. From there, develop a mental outline or checklist of how you’ll proceed. This approach not only keeps you organized but also reduces cognitive overload during more complex tasks. A structured mindset will allow you to work efficiently even under time pressure.
Time management during PBQs is vital. These questions can take longer than expected, especially if you’re unfamiliar with the tools or the format. If a particular scenario becomes too time-consuming or confusing, use the option to flag it and move on. It's better to return with a fresh perspective than to get stuck and lose valuable time needed for other questions. Practicing with PBQ simulations before the exam can help you recognize patterns and build the speed necessary to complete them more efficiently.
In preparation, make PBQ practice a regular part of your study routine. Look for online labs, simulation platforms, or PBQ-style exercises from reputable training providers. These resources replicate the look and feel of the real exam, giving you a more accurate sense of how questions will appear and how they’re scored. Practice also improves your ability to navigate through interactive interfaces, understand question prompts quickly, and avoid common errors caused by haste or oversight.
While PBQs can feel intimidating, remember that they are designed to reflect the real-world tasks of a cybersecurity analyst. If you’ve been practicing with logs, working in virtual labs, configuring tools, and reviewing scan results as part of your study routine, you’re more prepared than you realize. These scenarios aren’t traps—they’re opportunities to demonstrate your skills in action. Treat each one as if you’re on the job, using your training and instincts to solve a live problem.
To build confidence, visualize yourself succeeding. Approach PBQs with a mindset of calm and control. You’ve studied for this. You’ve practiced. You’ve built a foundation of analytical skills and practical knowledge. The PBQs are simply a stage where you demonstrate what you already know. Keep your pacing steady, trust your preparation, and remember that each correct step brings you closer to passing the exam.
In summary, performance-based questions on the CYSA Plus exam test your real-world capabilities in cybersecurity analysis and response. They challenge you to think critically, apply tools and strategies, and make decisions in simulated operational settings. By understanding PBQ formats, practicing consistently, and maintaining a calm, structured approach, you’ll greatly improve your ability to navigate these scenarios successfully.
