Explanation

A Vanilla scan attempts to connect to all 65,535 TCP ports on a target - it's the most thorough (and most detectable) type of scan, hence the name "vanilla" (plain, unfiltered, nothing fancy).

• A (UDP) is wrong because UDP scans target UDP ports specifically, not all ports, and the question describes a comprehensive TCP connection attempt.
• B (Strobe) is wrong because a strobe scan is selective - it targets only specific ports or port ranges of interest (e.g., known service ports), not all 65,535.
• C (FTP bounce) is wrong because FTP bounce is an attack technique that exploits the FTP PORT command to proxy scans through an FTP server - it's a method of obscuring the scanner's origin, not a scan type defined by port range.

Memory tip: Think "vanilla = all" - just like vanilla ice cream is the default, all-inclusive flavor, a vanilla scan hits every single port with no filtering or selection.
