Q1. How does encryption contribute to system hardening? (★)
Answer: C. By protecting data at rest and in transit from unauthorized access
Encryption hardens a system by protecting data at rest and in transit from unauthorized access, ensuring confidentiality even if other defenses fail. Managing permissions and patching software are separate administrative controls that do not directly secure the data itself.
Q2. What is the PRIMARY purpose of a firewall?
Answer: C. To stop or block attacks
A firewall primarily functions to stop or block network attacks. While they can detect threats or filter malware, the other options describe secondary features or specific technologies rather than the core purpose of network filtering.
Q3. What is the recommended frequency for testing an organization's Business Continuity Plan (BCP)?
Answer: C. According to business needs and requirements
Business Continuity Plan testing frequency should be determined by business needs and requirements. Fixed schedules like annual or biannual testing are traps because they ignore the changing risk environment.
Q4. Which category of cloud services does a ready-to-use email service fall into?
Answer: C. SaaS
A ready-to-use email service is Software as a Service, or SaaS. You can eliminate IaaS and PaaS because they provide infrastructure or development environments rather than finished, fully managed end-user applications.
Q5. What is the primary goal of the Health Insurance Portability and Accountability Act (HIPAA)?
Answer: D. To ensure the security and privacy of patients' health information
HIPAA establishes rules to ensure the security and privacy of patient health information. The other options target different sectors, like credit card security or financial data, which fall under PCI DSS or GLBA.
Q6. What is the primary problem typically associated with decentralized access control?
Answer: C. Inconsistent control
The primary problem with decentralized access control is inconsistent policy enforcement. Because different locations manage their own access, security rules often vary widely, leading to dangerous gaps in coverage.
Q7. Which of the following is an example of a threat actor?
Answer: B. A nation-state-sponsored hacking group
Threat actors are the individuals or groups orchestrating cyberattacks. A nation-state group is an actor, whereas a phishing email is a vector, a vulnerability is a weakness, and a denial-of-service attack is an event.
Q8. Which aspect ensures that authorized users have timely and reliable access to information and resources?
Answer: A. Availability
Availability ensures that authorized users have reliable and timely access to data and systems when needed. Confidentiality protects against unauthorized disclosure, and integrity ensures data remains unaltered.
Q9. What type of physical access control mechanism involves the use of electronic cards or key fobs that contain unique identifying information?
Answer: A. Electronic access control
Electronic access control relies on electronic cards or key fobs containing unique identifying data to manage facility entry. Mechanical locks require physical keys, and biometrics rely on biological traits.
Q10. In the context of risk management, what is the purpose of risk mitigation?
Answer: D. To implement controls and countermeasures that reduce the likelihood or impact of identified risks
Risk mitigation applies proactive controls to reduce the likelihood or impact of identified risks. Disregarding risks or relying purely on reactive measures fails to minimize potential organizational damage.
Q11. Which of the following principles states that individuals should be held to a standard of doing what a reasonable person would do under similar circumstances?
Answer: B. Due care
Due care is the legal standard of practicing the level of reasonable responsibility a prudent person would exercise in similar circumstances. Due diligence is the ongoing practice of ensuring these required safeguards are actually maintained.
Q12. Which principle of the ISC2 Code of Ethics Canons highlights the importance of providing quality service to clients or employers?
Answer: D. Provide diligent and competent service to principals
The ISC2 Code of Ethics mandates providing diligent and competent service to principals, which means delivering quality work to employers and clients. The other options represent separate canons focused on society, integrity, and advancing the profession.
Q13. Which of the following controls safeguards an organization during a power outage?
Answer: D. UPS
An uninterruptible power supply provides immediate backup power to systems during an electrical outage. While redundant servers and RAID arrays improve availability, they cannot function without electricity, making a UPS the direct safeguard.
Q14. Which network security device is PRIMARILY responsible for monitoring network traffic and detecting potential threats based on predefined rules or signatures?
Answer: A. Intrusion Detection System (IDS)
An intrusion detection system monitors network traffic to detect potential threats using predefined rules or signatures. Firewalls actively block traffic based on rules, while proxy servers and VPN gateways serve different networking and security functions.
Q15. In the risk management process, which of the following best describes the concept of 'risk acceptance'?
Answer: D. Acknowledging that certain risks are too costly or impractical to mitigate and accepting the potential consequences
Risk acceptance means acknowledging that certain risks are too costly or impractical to mitigate and accepting the potential consequences. The trap is that implementing controls to eliminate all risk is impossible, while ignoring risks or avoiding the process entirely represents negligence, not informed acceptance.
Q16. What type of authentication factor is voice pattern recognition?
Answer: B. Something you are
Voice pattern recognition is a biometric factor classified as something you are, because it relies on unique physical or behavioral characteristics. The trap is confusing this with something you know, like a password, or something you have, like a physical token.
Q17. What is the primary goal of an Advanced Persistent Threat (APT) attack?
Answer: C. To gain unauthorized access to sensitive data and maintain a long-term presence in the target network
An Advanced Persistent Threat aims to gain unauthorized access to sensitive data and maintain a long-term, undetected presence in the target network. The trap is confusing APTs with denial of service attacks, which disrupt services, or malware designed to spread quickly.
Q18. Which of the following best describes non-repudiation in the context of digital signatures?
Answer: B. Providing proof that a specific sender sent a specific message
Non-repudiation provides undeniable proof that a specific sender sent a specific message, preventing them from denying the action. The distractors map to other security principles, such as confidentiality for unreadable messages and integrity for unaltered messages.
Q19. Which is the second phase of the data handling lifecycle?
Answer: C. Storage phase
The second phase of the secure data handling lifecycle is storage, where generated or received data is securely saved to servers or databases. The creation phase comes first, while sharing and destruction occur later in the data lifecycle.
Q20. What type of network attack involves an attacker creating a malicious email that appears to come from a legitimate source to trick recipients into revealing sensitive information or downloading malware?
Answer: C. Spear Phishing Attack
Spear phishing uses highly targeted, deceptive emails that appear to come from a trusted source to trick users into revealing sensitive data or downloading malware. Denial-of-service attacks disrupt availability, while on-path attacks intercept live network traffic.
