Question #41
Which network security feature helps protect against unauthorized data access and ensures confidentiality of sensitive information?
- A . Firewall
- B . VPN
- C . Intrusion Detection System
- D . Antivirus
Correct Answer: B
B
Explanation:
Option 1: Incorrect. A firewall is responsible for controlling incoming and outgoing network traffic based on predetermined security rules. While it can help protect against unauthorized access, it does not specifically ensure confidentiality of sensitive information.
Option 2: Correct. A VPN (Virtual Private Network) creates a secure, encrypted connection between a user’s device and a private network, such as a corporate network, over the internet. This helps protect against unauthorized data access and ensures the confidentiality of sensitive information.
Option 3: Incorrect. An Intrusion Detection System (IDS) monitors network traffic for suspicious activity or known attack patterns.
While it can help detect and alert to potential unauthorized access attempts, it does not specifically ensure confidentiality of sensitive information.
Option 4: Incorrect. An antivirus software is used to detect, prevent, and remove malware infections. While it can help protect against unauthorized access, it does not specifically ensure confidentiality of sensitive information.

Question #42
Which of the following is an important aspect of ensuring that endpoint systems meet security policies and standards?
- A . Implementing software firewalls
- B . Enforcing strong password policies
- C . Conducting periodic software audits
- D . Regularly updating firmware
Correct Answer: B
B
Explanation:
Enforcing strong password policies is an important aspect of ensuring that endpoint systems meet security policies and standards. Strong passwords help prevent unauthorized access to the system and protect sensitive information. While firmware updates, software firewalls, and software audits are also important for overall cybersecurity, enforcing strong password policies directly relates to the security of endpoints and their compliance with policies and standards.

Question #43
What is the primary characteristic of an Advanced Persistent Threat (APT) compared to traditional attacks?
- A . APTs are easily detectable by conventional security measures
- B . APTs involve persistent and prolonged attacks on specific targets
- C . APTs are random and indiscriminate in their targets
- D . APTs are primarily aimed at causing immediate damage to systems
Correct Answer: B
B
Explanation:
The primary characteristic of an APT is its persistent and prolonged nature. Unlike traditional attacks, which may be brief and target multiple entities, APTs specifically focus on a particular target for an extended period of time. This allows the attackers to gather more information and potentially cause significant damage.

Question #44
What does the term "system logs" refer to in cybersecurity?
- A . Files containing network traffic data
- B . Records of user activity on a computer system
- C . Logs generated by operating systems that record events and activities
- D . Information relating to the hardware components of a computer system
Correct Answer: C
C
Explanation:
System logs, also known as event logs, are generated by operating systems and capture various events and activities that occur within a computer system. These logs provide valuable information for troubleshooting, detecting security incidents, and monitoring system health. They can include details about user logins, system errors, successful and failed login attempts, file access, network connections, and much more. Analyzing system logs is an essential part of cybersecurity, as it helps identify security breaches, anomalies, and potential threats.

Question #45
What is smishing?
- A . A form of social engineering attack that uses SMS or text messages to trick victims into revealing sensitive information.
- B . A physical attack where an unauthorized person gains entry to a restricted area by following closely behind an authorized person.
- C . A type of phishing attack that targets specific individuals or organizations.
- D . A cyber attack where an attacker manipulates and deceives an individual to reveal sensitive
information.
Correct Answer: A
A
Explanation:
Smishing, short for SMS phishing, is a social engineering attack that utilizes SMS or text messages to deceive individuals into disclosing sensitive information or performing certain actions. These messages often mimic legitimate sources, such as banks or service providers, and typically contain links or phone numbers that, when accessed or called, lead to malicious activities. Smishing takes advantage of the ubiquity of mobile devices and users’ tendency to trust text messages.

Question #46
What does the term "data classification" refer to in the context of cybersecurity?
- A . Protecting data from unauthorized access
- B . Sorting data based on its importance and sensitivity
- C . Backing up data to prevent data loss
- D . Encrypting data to ensure confidentiality
Correct Answer: B
B
Explanation:
Data classification is the process of categorizing data based on its importance, sensitivity, and the level of protection required. This helps ensure that appropriate security measures are applied to protect different types of data.
