CISSP Practice Test: 125 Cybersecurity Questions Across 5 Domains
The CISSP certification is the gold standard in information security. (ISC)2 reports that CISSP holders earn an average salary of $151,000 to $175,000 in the United States, according to the (ISC)2 Cybersecurity Workforce Study. The exam has a first-time pass rate estimated at 50-60%, meaning up to half of all candidates fail on their initial attempt at $749 per sitting.
Official (ISC)2 training runs $2,500 to $3,500 for classroom courses. Boson practice exams cost $99 for 750 questions. SANS courses exceed $7,000. Our CISSP practice test delivers 125 questions across all 8 CISSP domains with every answer explained for $99 one-time.
To be clear: this is an authentic practice test built using the ALA Mirror Method to replicate the real CISSP exam's structure, domain distribution, and difficulty curve. Every question is 100% original, written by Guinness World Records Puzzle Master Timothy E. Parker.
What Is the CISSP Exam?
The CISSP (Certified Information Systems Security Professional) exam tests advanced knowledge across 8 security domains. The current CAT (Computer Adaptive Testing) format presents 125 to 175 questions over a 4-hour window.
- Security & Risk Management — governance, compliance, ethics, business continuity
- Asset Security — data classification, ownership, retention, privacy protection
- Security Architecture & Engineering — cryptography, secure design, physical security
- Communication & Network Security — network architecture, protocols, secure channels
- Identity & Access Management — authentication, authorization, access control models
- Security Assessment & Testing — vulnerability scanning, penetration testing, auditing
- Security Operations — incident response, disaster recovery, forensics
- Software Development Security — SDLC, secure coding, application vulnerabilities
The passing threshold is 700 out of 1000. Candidates must have at least 5 years of cumulative paid work experience in two or more of the 8 domains, or 4 years plus a qualifying degree. The exam fee is $749.
How the ALA Mirror Method Works
The ALA Mirror Method is the framework behind every practice test on US Testing Center. For the CISSP practice test, it operates on three principles:
- Exact structural replication. The test contains exactly 125 questions distributed across all 8 CISSP domains in the same proportions as the real exam. Each domain carries the same weight here as it does on test day.
- Calibrated difficulty curve. Approximately 30% of questions are classified as easy, 50% as medium, and 20% as hard. This mirrors the real exam's distribution philosophy, blending straightforward recall with multi-layered analytical problems.
- 100% original content. Every question is written by Guinness World Records Puzzle Master Timothy E. Parker—the same author behind over 30 years of nationally syndicated test content. No recycled questions, no unlicensed material.
The result: a practice experience that measures the same skills the real CISSP exam measures, without requiring you to spend thousands on a commercial prep course to access quality questions.
Sample Questions with Full Explanations
The following three questions come directly from the practice test. They span three difficulty levels—easy, medium, and hard—and demonstrate the kind of teaching explanation included with every question in your report.
An organization wants to determine whether the cost of implementing a security control is justified by the risk it mitigates. Which of the following analysis methods should be used?
Quantitative risk analysis assigns monetary values to assets, threats, and controls, allowing a direct cost-benefit comparison. The Annual Loss Expectancy (ALE) formula quantifies expected losses, and comparing pre-control ALE minus post-control ALE against control cost determines whether implementation is financially justified. Qualitative risk analysis (A) uses subjective ratings rather than monetary values. A vulnerability assessment (C) identifies weaknesses but does not calculate cost justification. A business impact analysis (D) evaluates the effects of disruption but does not directly compare control costs to risk reduction.
An organization needs to ensure both the confidentiality and authenticity of email communications. Which combination of cryptographic operations should be applied?
To ensure confidentiality, the message is encrypted with the recipient's public key (only the recipient's private key can decrypt it). To ensure authenticity, the sender signs the message with their own private key (the recipient verifies using the sender's public key). Option A encrypts with the sender's public key, which only the sender could decrypt, defeating the purpose. Options C and D misapply the key pairs, violating fundamental asymmetric cryptography principles.
During a forensic investigation of a compromised server, the incident response team must collect evidence. According to the order of volatility, which evidence source should be collected FIRST?
The order of volatility dictates that the most volatile evidence be collected first. RAM contents are the most volatile because they are lost when the system is powered off or rebooted. The order from most to least volatile is: CPU registers and cache, RAM, temporary file systems, hard drive data, remote logs, archival media. Hard drive images (A) are less volatile than RAM. Remote syslog data (B) is persistently stored and among the least volatile. Network configurations (D) are stored in non-volatile memory on the device.
Every question in the full 125-question test includes this level of explanation—not just the correct answer, but the reasoning behind each wrong answer and the conceptual framework you need to internalize.

5 Dimensions Scored
Governance & Risk Management
Security Architecture & Engineering
Network & Communication Security
Identity & Access Management
Security Operations & Response
This dimension structure tells you more than a single score ever could. A test-taker scoring 80% overall but only 55% in one dimension has a clear, actionable target for improvement. The radar chart in your report makes these gaps immediately visible.
