Question 4:
Which protocol is used to securely transmit web pages over the Internet?
A. HTTP
B. FTP
C. HTTPS
D. SMTP
Answer: C. HTTPS
Explanation: HTTPS (HyperText Transfer Protocol Secure) is used to securely transmit web pages by encrypting the data exchanged between the user's browser and the web server, ensuring data integrity and confidentiality.
Question 5:
What is the primary purpose of a VPN (Virtual Private Network)?
A. To speed up internet connections
B. To provide secure access to a private network over a public network
C. To filter web content
D. To detect and prevent malware infections
Answer: B. To provide secure access to a private network over a public network
Explanation: A VPN creates a secure tunnel between the user's device and the private network, allowing secure access to network resources and protecting data from interception over public networks.
Question 6:
Which type of malware is designed to replicate itself and spread to other computers?
A. Spyware
B. Trojan
C. Worm
D. Adware
Answer: C. Worm
Explanation: Worms are a type of malware that can replicate themselves and spread to other computers without user intervention, often exploiting vulnerabilities in software or network configurations.
Question 7:
In the context of cybersecurity, what does the principle of "least privilege" refer to?
A. Providing users with minimal access rights needed to perform their job functions
B. Encrypting all sensitive data
C. Regularly updating antivirus software
D. Implementing the most restrictive firewall rules
Answer: A. Providing users with minimal access rights needed to perform their job functions
Explanation: The principle of least privilege involves giving users only the access rights they need to perform their tasks, minimizing the risk of unauthorized access or accidental misuse of sensitive information.
Question 8:
Which of the following is a common method used to verify the integrity of data?
A. Symmetric encryption
B. Hashing
C. Asymmetric encryption
D. Steganography
Answer: B. Hashing
Explanation: Hashing is used to generate a fixed-size string (hash value) from data. Any change in the data will result in a different hash value, thus helping to verify data integrity by comparing hash values.
Question 9:
What is the main function of a DMZ (Demilitarized Zone) in network security?
A. To serve as a buffer zone between an internal network and external networks
B. To store backup data
C. To filter email traffic
D. To monitor internal network activity
Answer: A. To serve as a buffer zone between an internal network and external networks
Explanation: A DMZ is a physical or logical subnetwork that contains and exposes an organization’s external-facing services to an untrusted network, typically the Internet, while keeping the internal network secure.
Question 10:
What is the purpose of two-factor authentication (2FA)?
A. To reduce the need for strong passwords
B. To provide an additional layer of security by requiring two forms of verification
C. To encrypt data during transmission
D. To filter spam emails
Answer: B. To provide an additional layer of security by requiring two forms of verification
Explanation: Two-factor authentication (2FA) enhances security by requiring two different forms of identification (something you know and something you have) before granting access to an account or system, reducing the likelihood of unauthorized access.

Question 11:
What is a honeypot in the context of cybersecurity?
A. A tool for encrypting data
B. A decoy system designed to lure attackers
C. A software used for scanning network vulnerabilities
D. A type of firewall configuration
Answer: B. A decoy system designed to lure attackers
Explanation: A honeypot is a decoy system intentionally set up to attract and trap attackers, allowing security professionals to study attack methods and gather intelligence without risking critical systems.
Question 12:
Which of the following best describes a zero-day vulnerability?
A. A vulnerability that has been patched
B. A vulnerability that is known but not yet exploited
C. A vulnerability that is publicly disclosed before a patch is available
D. A vulnerability in software that has been exploited for years
Answer: C. A vulnerability that is publicly disclosed before a patch is available
Explanation: A zero-day vulnerability is a software flaw that is unknown to the software vendor and for which no patch is available, making it a high-risk target for attackers.
Question 13:
Which of the following is the best practice for creating strong passwords?
A. Using common words or phrases
B. Combining letters, numbers, and special characters
C. Using short, memorable passwords
D. Writing passwords down on paper
Answer: B. Combining letters, numbers, and special characters
Explanation: Strong passwords should be a combination of letters (both uppercase and lowercase), numbers, and special characters to increase complexity and reduce the likelihood of being guessed or cracked.
Question 14:
What is the main purpose of a Security Information and Event Management (SIEM) system?
A. To encrypt sensitive data
B. To monitor and analyze security events in real-time
C. To manage user access controls
D. To perform vulnerability assessments
Answer: B. To monitor and analyze security events in real-time
Explanation: A SIEM system aggregates and analyzes data from various sources to provide real-time monitoring, detection, and response to security events, helping organizations identify and mitigate potential threats.

Question 18:
What is the primary goal of encryption in cybersecurity?
A. To compress data for faster transmission
B. To hide data from unauthorized users
C. To verify the identity of users
D. To backup data regularly
Answer: B. To hide data from unauthorized users
Explanation: The primary goal of encryption is to protect the confidentiality of data by converting it into a format that can only be read by someone who has the decryption key, thus preventing unauthorized access.
