Q1. What is Nmap?

• A web browser
• An operating system
• A network scanning tool
• An antivirus software

Q2. What is the primary purpose of Nmap?

• To optimize network performance
• To analyze network traffic
• To discover hosts and services on a computer network, thus creating a "map" of the network
• To encrypt data transmission

Q3. What operating systems is Nmap available for?

• Windows only
• Windows, Linux, macOS, and Unix-like systems
• macOS only
• Linux only

Q4. What types of scans can Nmap perform?

• Audio scans
• Video scans
• TCP and UDP port scans, host discovery scans, version detection scans, and OS detection scans
• Physical scans

Q5. What is a port in networking?

• A physical device used for network communication
• A type of network cable
• A virtual endpoint where data is sent and received on a computer network
• A software application for managing network configurations

Q6. How does Nmap determine which ports are open on a target system?

• By guessing randomly
• By sending email requests
• By sending specially crafted packets to target ports and analyzing the responses
• By checking the system's user manual

Q7. What is the purpose of Nmap's version detection feature?

• To optimize network performance
• To analyze network traffic
• To determine the version of software and services running on open ports, providing valuable information for further exploitation or vulnerability assessment
• To encrypt data transmission

Q8. How do you specify target hosts in Nmap?

• By typing random IP addresses
• By selecting hosts from a list
• By specifying IP addresses, IP ranges, hostnames, or CIDR notation in the command line
• By clicking on icons in the user interface

Q9. What is a SYN scan in Nmap?

• A scan for audio files
• A scan for video files
• A TCP scan technique where Nmap sends SYN packets to target ports and analyzes the responses to determine if the port is open, closed, or filtered
• A physical scan of network devices

Q10. How do you perform a SYN scan in Nmap?

• By typing random commands
• By sending email requests
• By using the -sS option in the Nmap command followed by the target IP address or hostname
• By clicking on buttons in the user interface

Q11. What is an OS detection scan in Nmap?

• A scan for audio files
• A scan for video files
• A scan technique where Nmap attempts to identify the operating system running on target hosts by analyzing various network responses and characteristics
• A physical scan of network devices

Q12. How do you perform an OS detection scan in Nmap?

• By typing random commands
• By sending email requests
• By using the -O option in the Nmap command followed by the target IP address or hostname
• By clicking on buttons in the user interface

Q13. What is a UDP scan in Nmap?

• A scan for audio files
• A scan for video files
• A scan technique where Nmap sends UDP packets to target ports and analyzes the responses to determine if the port is open, closed, or filtered
• A physical scan of network devices

Q14. How do you perform a UDP scan in Nmap?

• By typing random commands
• By sending email requests
• By using the -sU option in the Nmap command followed by the target IP address or hostname
• By clicking on buttons in the user interface

Q15. What is the purpose of Nmap's script scanning feature?

• To generate random network traffic
• To analyze network performance
• To run custom scripts or modules against target hosts to gather additional information, detect vulnerabilities, or perform specific tasks
• To encrypt data transmission

Q16. How do you perform script scanning in Nmap?

• By sending text messages
• By typing random commands
• By using the --script option in the Nmap command followed by the name of the script or script category, and the target IP address or hostname
• By clicking on buttons in the user interface

Q17. What is the purpose of Nmap's output options?

• To print network diagrams
• To generate random network traffic
• To customize the format and content of Nmap scan results, allowing for easier analysis and integration with other tools or scripts
• To optimize network performance

Q18. How do you specify output options in Nmap?

• By typing random commands
• By sending email requests
• By using the -oN, -oX, -oG, -oA, or -o options in the Nmap command followed by the desired output filename or format
• By clicking on buttons in the user interface

Q19. What is the purpose of Nmap's timing options?

• To adjust the system clock
• To generate random network traffic
• To control the speed and aggressiveness of Nmap scans, balancing thoroughness with network impact and speed
• To encrypt data transmission

Q20. How do you specify timing options in Nmap?

• By typing random commands
• By sending text

messages

• By using the -T option followed by a timing template (e.g., -T4 for aggressive scanning) in the Nmap command
• By clicking on buttons in the user interface
