- A: SNMP querying
- B: TCP/IP fingerprinting
- C: UDP segment analysis
- D: ICMP error messaging
Correct Answer: B
Explanation: TCP/IP fingerprinting involves analyzing the way a host responds to various network requests. This technique is used to predict the operating system of a remote host, as different operating systems respond uniquely to similar network requests, providing clues about the host's environment.
---

Question 13: Which type of scan is most effective for bypassing firewall rules and avoiding detection during a network scan?
- A: Stealth SYN scan
- B: Xmas scan
- C: FIN scan
- D: Connect scan
Correct Answer: A
Explanation: The stealth SYN scan is a type of network scanning that sends a SYN packet to initiate a TCP session but does not complete the handshake, making it less likely to be logged by the target's firewall. This approach is preferred for minimizing detection during reconnaissance.
---
________________________
Question 14: In network security testing, what is the main purpose of performing a ping sweep?
- A: To filter out unauthorized access points.
- B: To overload the network with excessive traffic.
- C: To measure the round-trip time for packet delivery to each host.
- D: To identify all active hosts on a network by sending ICMP echo requests.
Correct Answer: D
Explanation: A ping sweep involves sending ICMP echo requests (ping) to multiple hosts within a network to identify which ones are active. This is a fundamental technique in network mapping, providing a baseline for further more detailed scanning and vulnerability assessment.
---
________________________
Question 15: When an ethical hacker uses a SYN scan, what are they trying to achieve?
- A: To corrupt the target system’s TCP stack.
- B: To disconnect existing TCP connections by sending reset packets.
- C: To initiate a connection to a port without completing the TCP handshake.
- D: To establish a full TCP connection with the target.
Correct Answer: C
Explanation: A SYN scan, also known as a half-open scan, is used to check for listening ports on the target system. The scanner sends a SYN packet as if it is going to open a full TCP connection but closes the connection before the handshake is completed. This method is used to quickly identify open ports without establishing a full connection, reducing the likelihood of detection.
