What does the -oA option do in an Nmap command?

• A. Saves outputs in all formats simultaneously with a common filename prefix.
• B. Saves outputs only in normal format.
• C. Disables output.
• D. Saves as JSON.

Answer: (A)

The option -oA saves the scan results in all supported output formats at once using a common base filename. This is useful because you get multiple formats from a single run: a human-friendly normal file, an XML file for structured data, and a grepable file for quick text parsing, all sharing the same prefix. For example, using a base name like myscan will produce myscan.nmap, myscan.xml, and myscan.gnmap. It’s effectively a shorthand for running the separate output options (-oN, -oX, and -oG) together. This isn’t about disabling output, nor about saving only normal format, and it isn’t specifically about JSON.
