20+ practice questions focused on Security — one of the most tested topics on the CompTIA ITF+ FC0-U61 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Security PracticeA small business owner wants to protect sensitive customer data stored on a laptop that is frequently used on public Wi-Fi networks. The owner is considering implementing a security control that ensures data remains confidential even if the laptop is stolen. Which of the following is the BEST control for this scenario?
Explanation: Full-disk encryption (FDE) protects data at rest by encrypting the entire storage volume, typically using AES-128 or AES-256. Even if the laptop is stolen, the encrypted data remains unreadable without the decryption key, ensuring confidentiality. This directly addresses the requirement for data protection after physical theft.
A security analyst is reviewing user permissions and discovers that several users have been granted more privileges than necessary to perform their job functions. The analyst wants to apply the principle of least privilege. Which TWO actions should the analyst take? (Choose TWO.)
Explanation: Auditing current permissions (Option B) is the first step in applying least privilege because it identifies exactly which users have excessive rights. Creating RBAC groups (Option C) then allows the analyst to assign permissions based on job functions, ensuring users only have the access necessary to perform their roles. Together, these actions systematically reduce privilege levels without disrupting operations.
A help desk technician receives an alert from the security monitoring system showing multiple events like the one in the exhibit. The technician is investigating a possible brute-force attack. Based on the exhibit, which of the following is the primary attack vector being used?
Explanation: The exhibit shows repeated failed authentication attempts targeting TCP port 3389, which is the default port for Remote Desktop Protocol (RDP). A brute-force attack on RDP involves systematically trying many username/password combinations to gain unauthorized remote access to a Windows system. This matches the definition of an RDP brute-force attack.
You are the IT security administrator for a mid-sized law firm that handles sensitive client data. The firm has a mix of Windows 10 workstations, a Windows Server 2019 domain controller, and a network printer. All users have standard user accounts. The senior partner recently received a phishing email that appeared to be from a known client, requesting that he click a link to review a document. He clicked the link and entered his domain credentials on a fake login page. Shortly after, the firm's file server began encrypting files and displaying a ransom note. The incident response team isolated the infected server and restored files from backup. However, the senior partner now reports that he cannot access the file server from his workstation. He receives an 'Access Denied' message. You check his account in Active Directory and find that his account is not locked out and the password is correct. The file server is back online and accessible by other users. You verify that the senior partner's workstation has network connectivity and can ping the file server. Which of the following is the MOST likely cause of the access issue?
Explanation: The senior partner's password was likely changed during the incident response process to prevent further unauthorized access using his compromised credentials. When a password is changed in Active Directory, the user's workstation still caches the old credentials (NTLM hash) until the user logs off and back on. Since the partner has not logged off, his workstation continues to present the old, invalid credentials to the file server, resulting in an 'Access Denied' error despite the account being active and the password being correct.
Which TWO of the following are examples of social engineering attacks?
Explanation: Tailgating (option C) is a social engineering attack where an unauthorized person physically follows an authorized individual into a restricted area, bypassing access controls such as card readers or biometric scanners. This exploits human courtesy or inattention rather than technical vulnerabilities, making it a classic social engineering technique.

Practice all Security questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Security. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Security questions on the FC0-U61 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Security is tested as part of the CompTIA ITF+ FC0-U61 blueprint. Practicing with targeted Security questions ensures you can handle any format or difficulty that appears.
Yes. Courseiva provides free FC0-U61 practice questions across all exam topics and domains. The platform includes topic-based practice, mock exams, missed-question review, bookmarked questions, and readiness tracking — no account required.
