6 Free CompTIA Security+ SY0-701 Security Operations Practice Questions with Answers

Sample Question 1 — Security Operations

Your organization experiences a sudden surge in failed login attempts from various geographic locations. Security logs indicate unusual activity targeting administrative accounts. What is the MOST effective initial response?

  1. A. Immediately reset all administrative passwords.
  2. B. Implement a global password change policy requiring immediate updates.
  3. C. Temporarily lock out accounts exhibiting suspicious activity and investigate. (Correct answer)
  4. D. Conduct a full system vulnerability scan to identify potential weaknesses.

Correct answer: C

Explanation: Locking out suspicious accounts prevents further unauthorized access while allowing time for investigation. Resetting all passwords (A) is disruptive and may not address the root cause. A global password change (B) is also disruptive and slow; it doesn't address the immediate threat. A vulnerability scan (D) is important but should be done after containing the immediate threat. The priority is to stop the ongoing attack.

Sample Question 2 — Security Operations

An employee reports their laptop was stolen containing sensitive customer data. What is the FIRST action your incident response team should take?

  1. A. Initiate a full forensic analysis of the laptop.
  2. B. Notify affected customers immediately.
  3. C. Isolate the affected systems from the network. (Correct answer)
  4. D. Conduct a vulnerability assessment of the network.

Correct answer: C

Explanation: The immediate priority is to contain the breach and prevent further data compromise. Isolating affected systems prevents potential lateral movement. Notifying customers (B) is crucial, but should happen after containment. Forensic analysis (A) is important but comes after containment. A vulnerability assessment (D) is a longer-term activity.

Sample Question 3 — Security Operations

Your SIEM system is alerting on a large number of events related to unusual outbound network traffic from a specific server. After investigating, you determine the server has been compromised and is sending data to a command-and-control server. What is the MOST appropriate next step?

  1. A. Immediately shut down the compromised server.
  2. B. Initiate a full malware scan of all systems on the network.
  3. C. Isolate the compromised server from the network. (Correct answer)
  4. D. Contact law enforcement to report the incident.

Correct answer: C

Explanation: Isolating the server prevents further exfiltration of data. Shutting down the server (A) is an option, but isolation allows for potential data recovery and forensic analysis first. A network-wide scan (B) is too broad and time-consuming as the source is already identified. While reporting to law enforcement (D) is important, containing the threat is the immediate priority.

Sample Question 4 — Security Operations

You're implementing a security information and event management (SIEM) system. What's the MOST critical factor to consider during the implementation phase?

  1. A. The number of alerts the SIEM can generate.
  2. B. The cost of the SIEM software and hardware.
  3. C. The ability to effectively correlate events and identify threats. (Correct answer)
  4. D. The user-friendliness of the SIEM's dashboard.

Correct answer: C

Explanation: The primary purpose of a SIEM is threat detection and response through event correlation. While cost (B) and user-friendliness (D) are important, effective threat detection (C) is paramount. Alert volume (A) is a factor, but manageable alert volume is more important than sheer quantity.

Sample Question 5 — Security Operations

Your organization recently experienced a ransomware attack. During the incident response, which activity should receive the HIGHEST priority?

  1. A. Restoring data from backups.
  2. B. Analyzing malware samples.
  3. C. Identifying the attack vector.
  4. D. Containing the spread of the ransomware. (Correct answer)

Correct answer: D

Explanation: Containing the ransomware's spread is crucial to prevent further damage. While data restoration (A), malware analysis (B), and identifying the attack vector (C) are important, limiting further damage takes precedence.

Sample Question 6 — Security Operations

Your organization uses a vulnerability scanner to identify security weaknesses in its systems. Which of the following BEST describes the primary limitation of vulnerability scanners?

  1. A. They cannot detect zero-day vulnerabilities. (Correct answer)
  2. B. They are expensive to implement and maintain.
  3. C. They require significant expertise to interpret results.
  4. D. They can only scan systems that are directly connected to the network.

Correct answer: A

Explanation: Vulnerability scanners rely on known vulnerabilities in their databases; therefore, they cannot identify zero-day vulnerabilities (newly discovered flaws). While options B, C, and D are challenges, they are not the primary limitation.
