Take our free CompTIA Security+ practice test with Smart Practice questions. Unlimited practice for the current exam covering all five domains with instant feedback, detailed explanations, and progress tracking—no credit card required.
The CompTIA Security+ certification is the industry's most widely held cybersecurity credential, accepted by the U.S. Department of Defense for DoD 8570/8140 compliance and required by thousands of employers worldwide. A practice test is the most effective preparation method because it engages active recall—the process of retrieving knowledge under pressure—which research consistently shows produces stronger retention than passive study techniques like re-reading notes.
Our free practice test removes the biggest barrier to quality exam prep: cost. While premium question banks charge $50–$150 for static sets that never change, our Smart Practice engine generates fresh, unique questions every session, preventing answer memorization and building genuine understanding of security concepts, threat landscapes, and defensive architectures.
| Domain | Exam Weight | Key Topics |
|---|---|---|
| General Security Concepts | 12% | CIA triad, zero trust, AAA, gap analysis |
| Threats, Vulnerabilities & Mitigations | 22% | Malware, social engineering, indicators of compromise |
| Security Architecture | 18% | Network segmentation, cloud security, resilience |
| Security Operations | 28% | Monitoring, incident response, vulnerability management |
| Security Program Management | 20% | Governance, risk management, compliance, auditing |
Q1: An attacker sends a carefully crafted email to a specific executive, impersonating a trusted vendor and requesting wire transfer authorization. Which type of social engineering attack is this?
A) Phishing B) Spear phishing C) Whaling D) Vishing
Answer: C) Whaling
Whaling is a highly targeted form of spear phishing that specifically targets senior executives or high-value individuals. The attack is customized with details that make it appear legitimate, such as impersonating a known vendor and referencing specific business processes like wire transfers.
Q2: A security analyst notices that a server is making outbound connections to an unknown IP address on port 443 every 30 minutes. Which type of indicator of compromise does this represent?
A) Beaconing B) Data exfiltration C) Privilege escalation D) Brute force
Answer: A) Beaconing
Beaconing describes regular, periodic outbound connections from a compromised host to a command-and-control server. The consistent 30-minute interval is a classic signature. While the traffic uses HTTPS (port 443) to blend in, the regularity distinguishes it from normal browsing patterns.
Q3: Which security model assumes that no user or device should be trusted by default, regardless of whether they are inside or outside the network perimeter?
A) Defense in depth B) Zero trust C) Least privilege D) Need to know
Answer: B) Zero trust
Zero trust architecture operates on the principle "never trust, always verify." Every access request is authenticated, authorized, and continuously validated regardless of network location. This contrasts with traditional perimeter-based models that trust internal traffic by default.
Traditional Security+ practice tests rely on fixed question pools of 300–500 questions. Once you cycle through them, you start recognizing answer patterns rather than learning the underlying security concepts. Our Smart Practice engine solves this by generating unique questions on demand using models trained specifically on current Security+ exam objectives.
Each question undergoes multiple validation steps: objective alignment verification, distractor quality assessment, and difficulty calibration. The engine also creates context-aware explanations that connect concepts across domains—for example, explaining how a social engineering attack (Domain 2) might bypass security controls (Domain 3) and trigger incident response procedures (Domain 4).
