CompTIA Security+ Practice Questions

Master the Security Operations Domain

Test your knowledge in the Security Operations domain with these 5 practice questions. Each question is designed to help you prepare for the CompTIA Security+ certification exam with detailed explanations to reinforce your learning.

Question 1

Which of the following is the best method to ensure that sensitive data is not stored on unauthorized devices?

A) Intrusion Detection System (IDS)

B) Data Loss Prevention (DLP)

C) Encryption

D) Firewalls

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: Data Loss Prevention (DLP) systems can monitor and control data transfer to unauthorized devices. OPTION A: An IDS detects intrusions but does not prevent data storage on unauthorized devices. OPTION B: Encryption protects data but does not prevent storage on unauthorized devices. OPTION C: Encryption protects data but does not prevent storage on unauthorized devices. OPTION D: Firewalls control network traffic but do not manage data storage.

Question 2

A cybersecurity team is responding to a malware outbreak in their network. What is the first action they should take to minimize damage?

A) Identify the malware variant

B) Isolate infected systems

C) Eradicate the malware

D) Update antivirus signatures

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: Isolating infected systems is the first action to prevent the malware from spreading to other parts of the network. OPTION A: Identifying the malware variant is important but secondary to containment. OPTION B: Correct answer. OPTION C: Eradication follows containment to remove the malware. OPTION D: Updating antivirus signatures is essential but not the immediate first step in an outbreak.

Question 3

An organization has discovered unauthorized access to their network. The security team determines that the attacker used stolen credentials. What is the best immediate action to mitigate this threat?

A) Implement multifactor authentication.

B) Change all user passwords.

C) Initiate a system-wide shutdown.

D) Conduct a forensic analysis.

Show Answer & Explanation

Correct Answer: A

Explanation: Implementing multifactor authentication adds an additional layer of security, making it harder for attackers to use stolen credentials. Changing all passwords is reactive and less effective if credentials continue to be compromised. A system shutdown can cause disruption and may not address the root cause. Forensic analysis is crucial for understanding the breach but does not immediately stop ongoing unauthorized access.

Question 4

A security analyst needs to ensure that an organization's network can quickly recover from a distributed denial-of-service (DDoS) attack. Which strategy is most effective?

A) Implementing network redundancy

B) Using strong passwords

C) Deploying an IDS

D) Conducting regular vulnerability scans

Show Answer & Explanation

Correct Answer: A

Explanation: CORRECT: Network redundancy ensures that alternative resources are available in case of a DDoS attack, aiding quick recovery. OPTION A: Strong passwords protect accounts but do not mitigate DDoS attacks. OPTION B: IDS detects attacks but does not ensure recovery. OPTION C: Vulnerability scans identify weaknesses but do not aid in DDoS recovery. OPTION D: Vulnerability scans identify weaknesses but do not aid in DDoS recovery.

Question 5

An organization wants to enhance its security posture by implementing a layered security approach. Which of the following best describes this strategy?

A) Using multiple firewalls to protect the network

B) Implementing security controls at multiple levels

C) Encrypting data both at rest and in transit

D) Conducting frequent penetration tests

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: A layered security approach involves implementing security controls at various levels to provide comprehensive protection. OPTION A: Using multiple firewalls is part of a layered approach but not the full strategy. OPTION B: Correct answer. OPTION C: Encryption is a part of layered security but not the complete strategy. OPTION D: Penetration tests are useful but not the essence of layered security.
