Free CompTIA Security+ Security Operations Practice Questions (2026)

A junior analyst sees a spike in WAF alerts on the e-commerce server. The logs show dozens of failed SQL queries from a single IP targeting the checkout page via port 443. Following the playbook to the letter, they declare a critical incident and isolate the server. The result: thirty minutes of prime-time revenue lost, only to learn it was the new third-party pen testing team starting their assessment without prior notification.

This isn't a failure of tools. It's a failure of judgment, and it's exactly the kind of trap the CompTIA Security+ exam sets for you in the Security Operations domain. You can try VoraPrep's free CompTIA practice questions to see how you handle similar scenarios under pressure.

Test Your Knowledge: 10 CompTIA Security Operations (SY0-701) Practice Questions

Take your time, read each question carefully, and select the best possible answer. The explanations follow each question.

Question 1

A security analyst is reviewing SIEM alerts and notices a single failed login attempt for the root account on a public-facing web server from an external IP address. The attempt occurred at 3:00 AM. No other suspicious activity from this IP address has been detected. How should the analyst classify this activity?

Answer and Explanation Correct Answer: B. As a security event Explanation: This activity is best classified as a security event. An event is any observable occurrence in a system or network. A single failed login, while notable, does not by itself constitute a security incident, which is an event that actually or potentially jeopardizes the confidentiality, integrity, or availability of an information system. This is routine internet "background noise." ⚠️ Exam trap: Answer A, "As a security incident," is the most common wrong answer. Candidates often overreact. CompTIA wants you to show judgment. Escalating every single failed login to a full-blown incident would be inefficient and create alert fatigue. The key is the context: it's a single attempt with no other correlated malicious activity.

• Why C is wrong: It's not a false positive. A failed login attempt did occur, so the alert is accurate. A false positive would be if the system alerted on something that didn't happen.
• Why D is wrong: While the event is "true," classifying it as a "true positive" is less precise than "security event." "True positive" is a term for an alert that correctly identifies malicious activity. We don't have enough information to confirm malicious intent versus a simple typo, but we know for sure it's an observable event.

Question 2

During an active incident response, a forensic investigator needs to collect evidence from a compromised server. According to the order of volatility, which of the following data sources should be collected FIRST?

Answer and Explanation Correct Answer: D. CPU registers and cache Explanation: The order of volatility dictates that evidence should be collected from the most volatile (temporary) to the least volatile (permanent). CPU registers and cache are the most volatile data, as their contents can be overwritten in nanoseconds and are lost the moment the system is powered down. The Order of Volatility (Most to Least):

1. CPU registers, cache
2. Routing tables, ARP cache, process tables, RAM (system memory)
3. Temporary file systems / swap space
4. Data on hard drives or other persistent storage
5. Remote logging and monitoring data
6. Archived media and backups

⚠️ Exam trap: Answer A, "Hard drive image," is a tempting choice because it's a critical part of forensics. However, it is one of the least volatile forms of data. If you take the time to image the hard drive first, all the live data in RAM and the CPU cache will be lost. The exam will test your knowledge of this specific sequence.

• Why B is wrong: The ARP cache is highly volatile because it resides in RAM, but it is less volatile than CPU registers.
• Why C is wrong: Archived log files are stored on non-volatile media (like a hard drive or remote server) and are among the last things you would collect.

Question 3

A company's incident response policy requires the use of a SOAR platform. What is the primary benefit of implementing SOAR?

Answer and Explanation Correct Answer: A. To automate and orchestrate incident response workflows Explanation: SOAR stands for Security Orchestration, Automation, and Response. Its core purpose is to take predefined workflows (playbooks) and automate them, integrating various security tools to respond to threats faster and more consistently than human analysts could alone. For example, a SOAR playbook could automatically quarantine a machine, block an IP address on the firewall, and open a trouble ticket when a specific high-fidelity alert is triggered. ⚠️ Exam trap: Answer C, "To replace the need for human security analysts," is a common misconception. SOAR is a force multiplier for analysts, not a replacement. It automates the tedious, repetitive tasks, freeing up human experts to focus on complex threat hunting, investigation, and strategic decision-making. CompTIA emphasizes the human element in security.

• Why B is wrong: This describes a SIEM (Security Information and Event Management) or a log management solution, not SOAR. While SOAR integrates with a SIEM, its primary function is action, not storage.
• Why D is wrong: This describes the function of an Intrusion Detection/Prevention System (IDS/IPS) or a Next-Generation Firewall (NGFW). SOAR would act on the alerts from these systems, but it doesn't perform the inspection itself.

Question 4

A security team is investigating a data breach. They have collected a compromised hard drive and created a forensic image. To ensure the integrity of the evidence, what should the investigator do immediately after creating the image?

Answer and Explanation Correct Answer: B. Generate a hash of the image file Explanation: Hashing is the process of creating a unique, fixed-size string of characters (a hash value or checksum) from a piece of data. Immediately after creating a forensic image, a hash (e.g., SHA-256) must be generated. This hash acts as a digital fingerprint. At any point in the future, the image can be re-hashed, and if the new hash matches the original, it proves that the evidence has not been altered. This is a fundamental step in maintaining the chain of custody. ⚠️ Exam trap: Answer A, "Encrypt the image file," sounds like a good security practice, and it is. However, it is not the first thing you do to ensure integrity. Hashing proves the data is unchanged, while encryption protects its confidentiality. The question specifically asks about integrity. You would typically hash the image first, then you might encrypt the hashed image for secure storage or transport.

• Why C is wrong: You should never boot the original drive. Doing so would alter countless files, timestamps, and system states, destroying the integrity of the evidence. Analysis is always performed on a copy (the image).
• Why D is wrong: Compression can be useful for storage, but it is not a primary step for ensuring integrity. The hash must be generated before any other operation that could potentially alter the file.

Question 5

An organization is conducting a disaster recovery test. The team activates the alternate processing site and restores data from backups. They then attempt to run business processes on the alternate site, but it fails. This scenario describes a failure in which phase of the incident response lifecycle?

Answer and Explanation Correct Answer: D. Recovery Explanation: The Recovery phase of the incident response lifecycle involves restoring systems to normal operation after a security incident or disaster. This includes restoring from backups, rebuilding systems, and validating that they are clean and fully functional. A failed disaster recovery test is a direct failure of the organization's ability to execute this phase. The test's purpose is to find these problems before a real disaster strikes. ⚠️ Exam trap: Answer A, "Preparation," is a tempting distractor. You could argue that the failure happened because the preparation was inadequate. While true, the question describes the actual test failing. The test itself is an exercise of the Recovery phase. The lessons learned from this failed test would then feed back into improving the Preparation phase for the future. CompTIA wants you to identify the phase being actively tested.

• Why B is wrong: Containment is about limiting the scope and magnitude of an incident as it happens (e.g., isolating a compromised host).
• Why C is wrong: Eradication is about removing the root cause of the incident (e.g., deleting malware, patching a vulnerability).

Question 6

A security analyst needs to review logs to investigate a suspected web application attack. The logs show the following entry:

192.168.1.10 - - [10/Oct/2026:13:55:36 -0700] "GET /products.php?id=1' OR '1'='1 HTTP/1.1" 200 1452

What type of attack does this log entry most likely indicate?

Answer and Explanation Correct Answer: B. SQL Injection (SQLi) Explanation: The key indicator is the payload 1' OR '1'='1. This is a classic tautology used in SQL injection attacks. The attacker is attempting to append this condition to a SQL query on the backend. Because '1'='1' is always true, this can bypass authentication or cause the database to dump all records in a table instead of just the one matching a specific ID. ⚠️ Exam trap: Answer A, "Cross-Site Scripting (XSS)," is a common web attack, but it involves injecting client-side scripts (like JavaScript) into a web page, which are then executed by other users' browsers. The payload would typically contain tags like <script> or event handlers like onload=, which are not present here.

• Why C is wrong: A DoS attack involves overwhelming a service with traffic. A single log entry like this is not indicative of a DoS attack.
• Why D is wrong: A directory traversal attack uses payloads like ../ to navigate the file system and access restricted files. That pattern is not seen in this log entry.

Question 7

Which of the following describes the primary purpose of a "chain of custody" form in a forensic investigation?

Answer and Explanation Correct Answer: B. To provide a chronological record of who handled the evidence Explanation: The chain of custody is a legal document that provides a detailed, chronological paper trail of every person who has had possession of a piece of evidence. It records who collected it, when they collected it, how it was stored and transported, and who it was transferred to. This is essential for ensuring the evidence is admissible in a court of law by proving it was not tampered with. ⚠️ Exam trap: The other answers all sound like plausible documentation steps, but they do not define the chain of custody. CompTIA expects you to know the precise legal and procedural meaning of this term. Answer C, "To authorize the seizure," is particularly tempting as it relates to legal process, but that function is served by a warrant or other legal authorization, not the chain of custody form itself.

• Why A is wrong: Technical specifications (e.g., hard drive model, size) would be recorded, but this is not the primary purpose. The main goal is tracking possession.
• Why D is wrong: Data classification is a separate process related to information governance, not evidence handling procedure.

Question 8

An organization's business continuity plan includes a hot site. What is the key characteristic of a hot site?

Answer and Explanation Correct Answer: B. It is a fully equipped and configured facility with live data synchronization. Explanation: A hot site is a disaster recovery site that is a near-exact replica of the primary production environment. It is fully equipped with hardware, software, and network connectivity, and data is actively replicated or synchronized to it. This allows for a near-immediate failover with minimal downtime (minutes to hours). It is the most expensive option but provides the highest level of availability.

Site Type	Equipment	Data	Recovery Time	Cost
Hot Site	Fully equipped	Synchronized (live)	Minutes to hours	Highest
Warm Site	Partially equipped	Needs restore	Hours to days	Medium
Cold Site	Basic infrastructure	Needs restore	Weeks to months	Lowest

⚠️ Exam trap: Answer C describes a warm site. This is a common point of confusion. The key differentiator between a hot site and a warm site is the state of the data. A hot site has live, synchronized data ready to go. A warm site has the hardware, but you still need to perform a potentially lengthy data restore from backups.

• Why A is wrong: This describes a cold site.
• Why D is wrong: While some DR sites can be shared, this doesn't define the "hot" characteristic. The defining feature is the readiness of the equipment and data.

Question 9

During the containment phase of an incident, a response team decides to place the compromised system into a sandbox environment. What is the primary goal of this action?

Answer and Explanation Correct Answer: B. To allow the malware to run in a safe, monitored environment to observe its behavior Explanation: This technique is a form of containment often called "isolation" or "segmentation." By moving the system to a sandbox (an isolated virtual environment), the incident response team can prevent the malware from spreading to other parts of the network. Crucially, it also allows them to safely observe the malware's behavior: what network connections does it try to make? What files does it create or modify? This intelligence is vital for the eradication and recovery phases. ⚠️ Exam trap: Answer A, "To eradicate the malware from the system," is what you do in the eradication phase, which comes after containment and investigation. The immediate goal of sandboxing is to contain and analyze, not to clean. Jumping straight to eradication without understanding the threat can lead to reinfection if the root cause isn't addressed.

• Why C is wrong: Restoring from backup is part of the recovery phase.
• Why D is wrong: Taking the system permanently offline might be a last resort, but it prevents any further analysis and may not be an acceptable business outcome.

Question 10

A company is concerned that employees are emailing sensitive customer data to their personal accounts, in violation of policy. Management wants a control that will actively stop this from happening. Which of the following would be the BEST control to implement?

Answer and Explanation Correct Answer: B. A preventative technical control Explanation: The goal is to actively stop the action. A preventative technical control, such as a Data Loss Prevention (DLP) solution configured to scan outbound emails and block any containing patterns that match customer data (like credit card numbers or Social Security numbers), is the best choice. It is technical (a system, not a policy) and preventative (it stops the event from occurring). ⚠️ Exam trap: Answer D, "A deterrent administrative control," is the most tempting wrong answer. This would be an Acceptable Use Policy (AUP) that all employees must sign. While an AUP is a necessary part of a security program, it does not actively stop a determined or careless employee. It only provides a basis for disciplinary action after the fact. The question asks for the BEST control to stop the action.

• Why A is wrong: A detective administrative control, such as a manager reviewing email logs weekly, would only identify the data exfiltration after it has already happened. This doesn't meet the requirement to stop the action.
• Why C is wrong: A physical control, like a locked server room door, is completely irrelevant to the risk of data being sent via email.

Your 7-Day Security Operations Turnaround Sprint

Regardless of your score, here is an actionable plan to solidify your Domain 4 knowledge this week.

Day 1-2: Solidify the Process

Focus exclusively on the incident response lifecycle as defined by NIST SP 800-61. Use flashcards to drill the phases: Preparation; Detection & Analysis; Containment, Eradication, & Recovery; and Post-Incident Activity. For each phase, write down two specific actions an analyst would take.

Day 3-4: Interpret the Evidence

This is log and tool output day. Instead of just reading about tools, actively seek out examples. Do Google image searches for "firewall log example," "nmap output," "dig output." Your goal is to become comfortable identifying key pieces of information (IP addresses, port numbers, DNS records) from raw text. The VoraPrep adaptive engine excels here by feeding you questions based on real-world outputs.

Day 5: Master Forensics

Drill the order of volatility until you can recite it from memory. Review the concepts of hashing, chain of custody, and data acquisition. Understand why you image a drive and why you never work on the original evidence.

Day 6: Timed Practice

Take a 20-question timed quiz focused only on Security Operations. You can create a custom quiz in VoraPrep to target just this domain. The time pressure simulates the real exam and forces you to make decisions quickly and accurately.

Day 7: Analyze and Refine

Review every question you got wrong on your timed quiz. Read the explanations carefully. Use the Vory tutor to ask clarifying questions like, "Why is this considered containment and not eradication?" or "Explain the difference between a hot site and a warm site again." This targeted review is the key to turning weaknesses into strengths.
