What port range is associated with a SYN scan mentioned in the material?

• A. 50-60
• B. 10-20
• C. 1-10
• D. 100-110

Answer: (A)

SYN scan works by sending a TCP SYN to each port in the chosen range and interpreting the responses to determine if a port is open, closed, or filtered. In the material, this technique is demonstrated over a small, consecutive set of ports, specifically the range from 50 to 60. Using this compact range keeps the example clear while showing how responses map to port states, which is why that range is the one associated with the demonstration. The other ranges aren’t the example used in that section; in practice you could scan any range, but the material uses 50-60 for illustration.
