Study tips
- Review the official exam content outline before your first practice run.
- Take the full practice exam once to establish a baseline score by category.

- Re-take missed questions in drill mode until you can explain each correct answer.
- Schedule the real exam only after consistent passing scores on practice tests.
Sample Security+ practice questions
Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.
- Question 1Threats and Vulnerabilities
An attacker sends emails that appear to be from payroll and ask employees to verify credentials on a fake login page. This is an example of:
- A.SQL injection
- B.Phishing(Correct)
- C.Pass-the-hash
- D.Bluejacking
Explanation
Phishing uses social engineering — often spoofed email and fraudulent sites — to steal credentials or deploy malware. The payroll pretext is a classic business-email pattern.
- Question 2Architecture
Which control type is a biometric fingerprint scanner used for facility entry?
- A.Administrative
- B.Physical(Correct)
- C.Corrective
- D.Detective software
Explanation
Biometric door readers are physical access controls. They complement logical controls like MFA but directly restrict who can enter a space.
- Question 3Cryptography
Which goal of cryptography ensures that a message has not been altered in transit?
- A.Non-repudiation only
- B.Integrity(Correct)
- C.Availability
- D.Obfuscation
Explanation
Integrity verifies data has not been tampered with, often via hashing or authenticated encryption. Non-repudiation proves who sent it; availability keeps systems reachable.
