Free CISSP Sample Questions
These sample questions are written in the style of real CISSP exam questions. They test conceptual understanding and "think like a manager" reasoning, not just factual recall. Answer each one before revealing the explanation.

Score:0 / 0
Domain 1: Security & Risk Management
1. A CISO is asked to justify the organization's security budget to the board of directors. Which approach is MOST effective for communicating security value in business terms?
Present a list of recent CVEs and their CVSS scores
Show the number of security incidents blocked last quarter
Quantify risk in financial terms using ALE and demonstrate ROI on controls
Demonstrate compliance with all applicable regulations
The CISSP approach: security decisions are business decisions. Boards understand financial impact. ALE (Annual Loss Expectancy) quantifies risk in dollars, and ROI demonstrates that control costs are justified by risk reduction. Compliance is a floor, not a ceiling, and technical metrics like CVE counts mean little to non-technical executives.
Domain 2: Asset Security
2. During a corporate acquisition, the security team discovers the acquired company stores customer PII in unencrypted flat files on employee laptops. What should be done FIRST?
Classify the data and assess the risk to determine the appropriate response
Immediately encrypt all files on all laptops
Delete the files and notify affected customers
Report the breach to the regulator immediately
CISSP "first step" questions almost always require classification and risk assessment before action. You need to understand the scope, sensitivity, and regulatory context before encrypting (which could disrupt operations), deleting (which may destroy evidence), or notifying regulators (which has specific legal triggers). Assess first.
Domain 5: Identity & Access Management
3. An organization uses role-based access control (RBAC). An employee is promoted and takes on new responsibilities that require access to additional systems. Their old access is not removed. What security issue does this create?
Separation of duties violation
Privilege creep (accumulation of excessive access rights over time)
Least privilege violation
Need-to-know violation
Privilege creep occurs when users accumulate access rights over time as their roles change, but old permissions are never revoked. It's a direct consequence of poor access lifecycle management and violates least privilege. The mitigation is regular access reviews (access recertification). Note: the result is a least privilege violation, but the cause and name of the pattern is privilege creep.
Domain 7: Security Operations
4. During incident response, the team discovers that an attacker has maintained persistent access to the network for six months. The team wants to eradicate the threat. What should they do BEFORE eradication?
Patch all vulnerable systems immediately
Notify law enforcement
Restore systems from backup
Fully scope the intrusion, identify all compromised systems and backdoors, to ensure complete eradication
Premature eradication is a common incident response mistake. If you patch and clean systems before fully scoping the intrusion, the attacker's remaining backdoors and persistence mechanisms survive. Complete scoping first ensures that eradication is comprehensive. Patching, notifying law enforcement, and restoring backups all come after scope is fully understood.
Domain 8: Software Development Security
5. A developer team implements input validation only on the client side of a web application. A security reviewer flags this as insufficient. Why?
Client-side validation is slower than server-side validation
Client-side validation can be bypassed by an attacker using a proxy or modified browser request
Client-side validation only works on HTTPS connections
Client-side validation (JavaScript, HTML5 attributes) is entirely under the attacker's control. It can be disabled, bypassed with a proxy like Burp Suite, or circumvented by sending crafted HTTP requests directly to the server. Server-side validation is the authoritative defense. Client-side validation improves UX but provides no security guarantee.

Start Your CISSP Prep With CertLabz, No Boot Camp Required
Self-paced, hands-on, and blockchain-verified. Skip the expensive in-person training and prove your CISSP-ready skills your way.
For most candidates, no. In-person boot camps are expensive, compressed into five days, and rarely cover CISSP's depth in that time. A self-paced, hands-on path with realistic practice questions and a measurable skill assessment is more flexible and far cheaper. CertLabz delivers exactly that with the CISSP Domain Refresher course certificate and the Cybersecurity Analyst Skill Track.
How many practice questions should I do before the CISSP?
Aim for 2,000 to 3,000 practice questions before sitting the exam. Quality matters more than quantity. Review every explanation, especially for questions you got right by guessing, and focus on internalizing the "think like a manager" reasoning pattern rather than memorizing specific answers.
How does CertLabz help me prepare for the CISSP?
CertLabz combines a CISSP Domain Refresher course certificate with the Cybersecurity Analyst Skill Track. You get hands-on virtual labs, domain-aligned practice questions, and a SkillTracker exam that produces a blockchain-verified certificate you can share with employers. Everything is self-paced and online, with no travel and no five-day calendar lockout. Many candidates also use CertLabz certificates toward CPE renewal for CompTIA, ISACA, EC-Council, and ISC2 credentials.
