SY0-701 CompTIA Security+ Exam 2026 Free Practice Exam Questions (2026 Updated)

The best answer is D. Conduct a phishing campaign.

To measure whether social engineering awareness training is effective, the best method is to run a simulated phishing campaign. This allows the organization to test employee behavior in a realistic but controlled way. The administrator can track who clicks suspicious links, opens attachments, submits credentials, or reports the email appropriately.

This is a practical and measurable way to evaluate training outcomes because it provides real performance data rather than opinions or assumptions.

Why the other options are incorrect:

A. Set up a honeypot.A honeypot is used to attract attackers or detect malicious activity, not to test employee awareness of social engineering.

B. Send out a survey.A survey may show how confident employees feel, but it does not objectively measure whether they can identify and resist real phishing attempts.

C. Set up a focus group.A focus group can gather feedback, but it is not the best method for testing actual security behavior.

From the SY0-701 perspective, user awareness training effectiveness is best measured through simulated phishing exercises and similar practical assessments.

The correct answer is A. Generator.

A generator can provide long-term backup power during an extended power outage, as long as sufficient fuel is available. For a multiday outage, a generator is the appropriate solution to keep a data center operational.

This aligns with CompTIA Security+ SY0-701 availability and resilience concepts. Data centers often use generators, redundant power feeds, UPS systems, and environmental controls to maintain uptime.

Why the other options are incorrect:

B. Uninterruptible power supply

A UPS provides short-term backup power and protects against brief outages, power fluctuations, and brownouts. It is usually designed to keep systems running until generator power starts or until systems can be shut down safely.

C. Replication

Replication copies data or systems to another location or system. It supports disaster recovery and availability, but it does not keep the same data center powered during an outage.

D. Parallel processing

Parallel processing distributes computing tasks across multiple processors or systems. It does not provide backup power.

Therefore, a generator is the best answer for a multiday power outage.

To mitigate the risk of confidential documents being left unattended in Multi-Function Printers (MFPs), implementing an authentication factor that requires in-person action before printing (such as PIN codes or badge scanning) is the most effective measure. This ensures that documents are only printed when the authorized user is present to collect them, reducing the risk of sensitive information being exposed.

Ransomware is a type of malware that encrypts the victim’s files and demands a ransom for the decryption key. The ransomware usually displays a message on the infected system with instructions on how to pay the ransom and recover the files. The .ryk extension is associated with a ransomware variant called Ryuk, which targets large organizations and demands high ransoms1.

Tokenization is widely used in the financial industry to mask sensitive information such as credit card numbers, bank account details, or payment tokens. Tokenization replaces sensitive data with harmless surrogate values (tokens) that maintain format and usability but reveal nothing if intercepted.

Security+ SY0-701 highlights tokenization as a preferred method for PCI-DSS-regulated environments because:

It reduces exposure of actual sensitive data

It lowers compliance scope

Tokens can be mapped back to real data only through a secure token vault

It prevents attackers from accessing meaningful information

Hashing (B) is one-way and cannot be reversed, making it unsuitable for financial transactions that require retrieving original values. Salting (C) enhances password hashing security but does not mask data. Steganography (D) hides data inside images or media files, not used for structured data protection.

Thus, the correct answer is A: Tokenization.

Integrating each SaaS solution with an Identity Provider (IdP) is the most effective way to address the security issue. This approach allows for Single Sign-On (SSO) capabilities, where users can access multiple SaaS applications with a single set of credentials while maintaining strong password policies across all services. It simplifies the user experience and ensures consistent security enforcement across different SaaS platforms.

Impossible travel (A)refers to logins fromgeographically distant locations within a time period that makes travel between them physically impossible. In this case, a user logging in fromChicago and Rome within a short timeframetriggers this anomaly.

This is a strong indicator of acompromised accountorstolen credentialsbeing used elsewhere.

The employee notices that the links in the email do not correspond to the company ' s official URLs, indicating that this is likely a social engineering attack. Social engineering involves manipulating individuals into divulging confidential information or performing actions that may compromise security. Phishing emails, like the one described, often contain fraudulent links to trick the recipient into providing sensitive information or downloading malware.

Business email refers to business email compromise (BEC), which typically involves impersonating a high-level executive to defraud the company.

Unsecured network is unrelated to the email content.

Default credentials do not apply here, as the issue is with suspicious links, not login credentials​​.

Wiping involves securely erasing data by overwriting the hard drive, ensuring the information is unrecoverable. It is cost-effective compared to physical destruction methods like shredding.

=================

SPF (Sender Policy Framework) DNS records specify which mail servers are authorized to send email on behalf of a domain. When new email servers are added but SPF records are not updated, recipient mail systems cannot verify the legitimacy of the new servers. As a result, those messages are flagged as spam or rejected altogether.

CompTIA Security+ SY0-701 highlights SPF as an essential email authentication mechanism used to reduce spoofing, phishing, and spam classification errors. Updating the SPF record to include the new servers ensures email reputation is maintained and messages are delivered properly.

CNAME (A) maps hostnames but does not affect outbound email legitimacy. SMTP (B) is the mail protocol, not the authentication method. DLP (C) governs sensitive data handling, not spam classification.

Thus, SPF is the correct answer.

An internal audit of a risk management program typically starts by verifying the organization has the governance foundation that defines how risk is managed, documented, approved, and monitored. That foundation is established in policies and procedures, which set expectations, roles, and the required workflow for consistent risk practices (for example: how risks are identified, who owns them, how they are tracked, and how exceptions are handled). The Study Guide emphasizes that policy is central to governance: “Policy serves as one of the primary governance tools for any cybersecurity program, setting out the principles and rules that guide the execution of security efforts throughout the enterprise.”

Without policies/procedures, the auditor cannot reliably assess whether asset management, vulnerability assessments, or BIAs are being performed according to an established, repeatable process—or whether results are being used appropriately in risk decisions. Asset management and vulnerability assessments provide critical inputs to risk identification and assessment, and the BIA supports impact determination and recovery planning, but an auditor usually first confirms that the organization’s documented governance structure exists and is being followed so the rest of the program can be evaluated against those requirements.

Multicloud architectures use two or more IaaS providers (e.g., AWS + Azure + GCP) to distribute workloads, increase redundancy, and reduce single points of failure. Security+ SY0-701 emphasizes multicloud strategies for enhancing:

Resilience

Availability

Fault tolerance

Geographic redundancy

Vendor independence

The question specifies:

Critical VMs

Hosted across different IaaS providers

Still maintained by internal application owners

This perfectly matches a multicloud deployment, where organizations maintain control over VM configuration while leveraging multiple cloud vendors for resilience.

SaaS provider diversity (B) applies to application services, not internally managed VMs.

On-prem load balancing (C) does not involve cloud providers.

Corporate-owned off-site locations (D) refer to DR sites, not multi-vendor cloud hosting.

Thus, A: Multicloud architectures is the correct answer.

Risk appetiterefers to thelevel of risk an organization is willing to acceptbefore implementing security measures. When expanding access controls, the company must assess how much risk is acceptable in terms ofdata exposure, unauthorized access, and compliance obligations.

Using a Privileged Access Management (PAM) vault to secure domain administrator credentials and enforcing role-based access control (RBAC) is the most comprehensive solution. PAM systems help manage and control access to privileged accounts, ensuring that only authorized personnel can access sensitive credentials. This approach also facilitates password rotation, auditing, and ensures that credentials are not misused or left unchanged. Integrating PAM with RBAC ensures that access is granted based on the user ' s role, further enhancing security.

The correct answer is B because regular patching directly reduces security risk by remediating known vulnerabilities before attackers can exploit them. Within the Security+ SY0-701 objectives, patch management is a foundational component of vulnerability management and secure operations. Vendors routinely release patches to fix security flaws that have already been identified, documented, and, in many cases, actively targeted by threat actors.

Attackers frequently scan enterprise environments for systems that are missing patches related to publicly disclosed vulnerabilities. Once a vulnerability is known, exploit code often becomes widely available, dramatically increasing the likelihood of compromise. Regular patching shortens the “window of exposure,” which is the time between vulnerability disclosure and remediation. By applying patches promptly, organizations significantly reduce the attack surface and limit opportunities for exploitation.

Option A is incorrect because while patches may incidentally improve stability or performance, that is not their primary security purpose. Option C is incorrect because patching does not replace other security controls; firewalls and intrusion detection systems remain essential for layered defense. Option D is also incorrect because antivirus tools serve a different role, such as detecting and responding to malware, and cannot be replaced by patching alone.

The SY0-701 study guide emphasizes that effective patch management requires structured processes, including testing, maintenance windows, rollback planning, and prioritization based on risk and asset criticality. Patching is classified as a preventive technical control, stopping attacks before they occur rather than reacting after compromise.

In summary, regular patching mitigates enterprise risk by proactively addressing known software vulnerabilities before they can be exploited. This makes it one of the most effective and widely emphasized security practices in the Security+ SY0-701 exam and in real-world security operations.

Comprehensive and Detailed Explanation From Exact Extract:

End-of-life (EOL) systems no longer receive security patches, vendor support, or vulnerability updates. Because of this, they are highly susceptible to exploitation, especially if attackers can reach them over a network. When the system is business-critical and cannot be decommissioned, the most effective strategy is isolation, also known as network segmentation, air-gapping, or restrictive network zoning. Isolation removes direct exposure to external and internal threats by limiting communication paths to only essential systems and users.

According to the Security+ SY0-701 guidance, isolating legacy systems helps reduce the attack surface when patching is no longer possible. Monitoring (A) is useful for detection but does not prevent exploitation. Decommissioning (C) would be ideal but is not possible for business-critical systems, as stated in the question. Encryption (D) protects data confidentiality but does not stop an attacker from exploiting vulnerabilities in an unpatched OS or application.

Isolation is a recommended compensating control for legacy and unsupported systems in SY0-701’s Security Architecture & Resilience domain, which emphasizes micro-segmentation, firewalls, and restricted access to minimize risk when systems cannot be replaced or patched.

This scenario describes a bug bounty program, which invites external security researchers to responsibly identify and report vulnerabilities in an organization’s systems. CompTIA Security+ SY0-701 defines bug bounty programs as structured initiatives that reward researchers for discovering and disclosing security flaws before they can be exploited by malicious actors.

Bug bounty programs extend security testing beyond internal teams and provide continuous, real-world testing of public-facing assets. They are particularly effective for identifying zero-day vulnerabilities, logic flaws, and edge-case issues that automated tools may miss.

Red teaming (B) is a controlled, internal or contracted adversarial exercise, not an open invitation. Open-source intelligence (C) involves gathering publicly available information, not vulnerability reporting. Third-party information sharing (D) refers to sharing threat intelligence, not soliciting vulnerability reports.

Because the CISO is inviting the broader security community to report vulnerabilities, the correct answer is A: Bug bounty.

When a legacy device is no longer receiving updates or patches, it is considered to be at the end of life (EOL). This means the manufacturer has ceased support for the device, and it will no longer receive updates, security patches, or technical assistance. EOL devices pose security risks and are often decommissioned or replaced.

End of support may seem similar but typically refers to the cessation of technical support, whereas EOL means the device is fully retired.

End of business and End of testing do not apply in this context​​.

When conducting a forensic analysis after an incident, it ' s essential to prioritize the data collection process based on the " order of volatility. " This principle dictates that more volatile data (e.g., data in memory, network connections) should be captured before less volatile data (e.g., disk drives, logs). The idea is to preserve the most transient and potentially valuable evidence first, as it is more likely to be lost or altered quickly.

Compromised vendor email accounts often lead to business email compromise (BEC) attacks where attackers send malicious or unexpected requests appearing from trusted sources. Training users to be alert to unexpected requests even if they appear to come from familiar addresses is critical in preventing such attacks.

Refraining from clicking images (A) is less effective than being vigilant about suspicious content and requests. Deleting emails from unknown providers (B) is not practical, as some legitimate emails come from unknown senders. Requiring invoices as attachments (C) can increase risk by encouraging users to open potentially malicious attachments.

This user awareness tactic is emphasized in the Security Program Management and Security Awareness training in SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】.

802.1X is the correct answer because it provides port-based network access control. It authenticates devices or users before allowing access through a switch port or wireless access point. In a typical deployment, the supplicant is the endpoint, the authenticator is the switch or access point, and the authentication server is often RADIUS. This allows an organization to prevent unauthorized devices from connecting to the internal network. EDR protects endpoints by detecting and responding to threats, but it does not provide port-based authentication. SASE is a cloud-delivered security architecture for secure access and networking. WPA3 strengthens wireless encryption and authentication, but the phrase “port-based authentication” specifically identifies 802.1X. Therefore, 802.1X best satisfies the requirement.

================

To identify the impacted host in a command-and-control (C2) server incident, the following logs should be analyzed:

DHCP logs: These logs record IP address assignments. By reviewing DHCP logs, an organization can determine which host was assigned a specific IP address during the time of the attack.

Firewall logs: Firewall logs will show traffic patterns, including connections to external C2 servers. Analyzing these logs helps to identify the IP address and port numbers of the communicating host.

Application, Authentication, and Database logs are less relevant in this context because they focus on internal processes and authentication events rather than network traffic involved in a C2 attack​​​.

Exercising the right to be forgotten involves formally requesting the social media provider to delete all personal data associated with the account, ensuring removal from their servers and backups in accordance with privacy regulations.

E-discovery (electronic discovery) is the process of identifying, collecting, and producing electronically stored information (ESI) in response to a legal request or investigation. It is a critical component of digital forensics when dealing with litigation, compliance, or regulatory matters.

 The data plane, also known as the forwarding plane, is the part of the network that carries user traffic and data. It is responsible for moving packets from one device to another based on the routing and switching decisions made by the control plane. The data plane is a critical component of the Zero Trust architecture, as it is where most of the attacks and breaches occur. Therefore, implementing Zero Trust principles within the data plane can help to improve the security and resilience of the network.

One of the key principles of Zero Trust is to assume breach and minimize the blast radius and segment access. This means that the network should be divided into smaller and isolated segments or zones, each with its own security policies and controls. This way, if one segment is compromised, the attacker cannot easily move laterally to other segments and access more resources or data. This principle is also known as threat scope reduction, as it reduces the scope and impact of a potential threat.

The other options are not as relevant for the data plane as threat scope reduction. Secured zones are a concept related to the control plane, which is the part of the network that makes routing and switching decisions. Subject role is a concept related to the identity plane, which is the part of the network that authenticates and authorizes users and devices. Adaptive identity is a concept related to the policy plane, which is the part of the network that defines and enforces the security policies and rules.

Side loading is the process of installing software outside of a manufacturer’s approved software repository. This can expose the device to potential vulnerabilities, such as malware, spyware, or unauthorized access. Side loading can also bypass security controls and policies that are enforced by the manufacturer or the organization. Side loading is often done by users who want to access applications or features that are not available or allowed on their devices. References = Sideloading - CompTIA Security + Video Training | Interface Technical Training, Security+ (Plus) Certification | CompTIA IT Certifications, Load Balancers – CompTIA Security+ SY0-501 – 2.1, CompTIA Security+ SY0-601 Certification Study Guide.

 Labeling all laptops with asset inventory stickers and associating them with employee IDs can provide several security benefits for a company. Two of these benefits are:

A. If a security incident occurs on the device, the correct employee can be notified. An asset inventory sticker is a label that contains a unique identifier for a laptop, such as a serial number, a barcode, or a QR code. By associating this identifier with an employee ID, the security team can easily track and locate the owner of the laptop in case of a security incident, such as a malware infection, a data breach, or a theft. This way, the security team can notify the correct employee about the incident, and provide them with the necessary instructions or actions to take,such as changing passwords, scanning for viruses, or reporting the loss. This can help to contain the incident, minimize the damage, and prevent further escalation.

F. Company data can be accounted for when the employee leaves the organization. When an employee leaves the organization, the company needs to ensure that all the company data and assets are returned or deleted from the employee’s laptop. By labeling the laptop with an asset inventory sticker and associating it with an employee ID, the company can easily identify and verify the laptop that belongs to the departing employee, and perform the appropriate data backup, wipe, or transfer procedures. This can help to protect the company data from unauthorized access, disclosure, or misuse by the former employee or any other party.

The other options are not correct because they are not related to the security benefits of labeling laptops with asset inventory stickers and associating them with employee IDs. B. The security team will be able to send user awareness training to the appropriate device. User awareness training is a type of security education that aims to improve the knowledge and behavior of users regarding security threats and best practices. The security team can send user awareness training to the appropriate device by using the email address, username, or IP address of the device, not the asset inventory sticker or the employee ID. C. Users can be mapped to their devices when configuring software MFA tokens. Software MFA tokens are a type of multi-factor authentication that uses a software application to generate a one-time password or a push notification for verifying the identity of a user. Users can be mapped to their devices when configuring software MFA tokens by using the device ID, phone number, or email address of the device, not the asset inventory sticker or the employee ID. D. User-based firewall policies can be correctly targeted to the appropriate laptops. User-based firewall policies are a type of firewall rules that apply to specific users or groups of users, regardless of the device or location they use to access the network. User-based firewall policies can be correctly targeted to the appropriate laptops by using the username, domain, or certificate of the user, not the asset inventory sticker or the employee ID. E. When conducting penetration testing, the security team will be able to target the desired laptops. Penetration testing is a type of security assessment that simulates a real-world attack on a network or system to identify and exploit vulnerabilities. When conducting penetration testing, the security team will be able to target the desired laptops by using the IP address, hostname, or MAC address of the laptop, not the asset inventory sticker or the employee ID. References = CompTIA Security+ Study Guide (SY0-701), Chapter 1: General Security Concepts, page 17. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 1.4: Asset Management, video: Asset Inventory (6:12).

Encryption is a reversible process that transforms cleartext data into ciphertext to protect confidentiality. It uses cryptographic keys to both encrypt and decrypt data, ensuring that only authorized parties can access the original data.

Hashing, on the other hand, is a one-way function that converts data into a fixed-length hash value or checksum. Hashing is primarily used to verify data integrity by detecting changes, since any modification in the input will produce a different hash output. Unlike encryption, hashing cannot be reversed to obtain the original data.

While encryption can protect data both at rest and in transit, hashing does not protect data confidentiality but supports integrity verification. Public-key exchange is a cryptographic mechanism within asymmetric encryption but is unrelated to hashing key usage.

This distinction is thoroughly explained in the Cryptography chapter of the SY0-701 syllabus【6:Chapter 7†CompTIA Security+ Study Guide】.

Operating system (OS) vulnerabilitiescan allow attackers to exploit system functions that affect multiple applications, leading towidespread compromise.

B (patch cycle concerns)is valid but not the primary concern—many OS vendors provide regular patches.

C (user trust in OS features)is a risk, but the more significant issue is thatOS vulnerabilities often affect multiple system components.

D (ease of exploitation)is not always true, as application and human-related vulnerabilities can be equally exploitable.

Thus,the main concern is that an OS exploit can impact multiple system functions, leading to broader security risks.

The lessons learned phase of an incident response process involves reviewing the incident and generating reports. This phase helps identify what went well, what needs improvement, and what changes should be made to prevent future incidents. Documentation and reporting are essential parts of this phase to ensure that the findings are recorded and used for future planning.

Recovery focuses on restoring services and normal operations.

Preparation involves creating plans and policies for potential incidents, not reporting.

Containment deals with isolating and mitigating the effects of the incident, not generating reports​​.

A legal hold is the correct answer because the organization is preserving potentially relevant evidence after a suspected breach involving sensitive client information. In incident response and governance, legal hold prevents deletion, alteration, or routine retention-policy destruction of data that may be required for litigation, regulatory investigation, discovery, or internal investigation. Logs, server images, and email communications are exactly the kinds of records that may become evidence. Chain of custody is related but narrower: it documents who handled evidence, when, and how integrity was maintained. Root cause analysis happens later to determine why the breach occurred. Containment focuses on stopping spread or limiting damage. Here, the key action is preservation of records.

===============

The first step in securing a newly deployed server is toclose unnecessary service ports. Open ports can expose the server to unauthorized access and potential cyber threats. By closing unused ports, the attack surface is reduced, limiting the number of entry points available to attackers.

Updating the software version (B)andupgrading the OS version (D)are important security measures but should follow the step of securing open ports to prevent immediate exposure to threats.

Adding the device to the Access Control List (ACL) (C)is a step in network security but does not directly secure the server itself against potential attacks.

Closing unnecessary ports helps in minimizing the risk of network-based attacks, such asport scanning and exploitation of default services.

Input validation is a technique that checks the user input for any malicious or unexpected data before processing it by the web application. Input validation can prevent cross-site scripting (XSS) attacks, which exploit the vulnerability of a web application to execute malicious scripts in the browser of a victim. XSS attacks can compromise the confidentiality, integrity, and availability of the web application and its users. Input validation can be implemented on both the client-side and the server-side, but server-side validation is more reliable and secure. Input validation can use various methods, such as whitelisting, blacklisting, filtering, escaping, encoding, and sanitizing the input data. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 2, page 70.

Software as a Service (SaaS) represents an application that is hosted in the cloud and accessible via the internet from anywhere, with no requirement for on-premises infrastructure. SaaS applications are managed by a third-party provider, allowing users to access them through a web browser, making them highly scalable and flexible for remote access.
