Which statement about the -oA output is correct?

• A. It saves Normal, XML, and Grepable outputs in a single run.
• B. It writes outputs only to the console.
• C. It requires a basename to generate file names.
• D. It is deprecated.

Answer: (A)

The key idea is that this option produces multiple output formats in one go. When you use it, Nmap writes three separate files from a single scan run, all sharing the same base name you provide. Specifically, you’ll get the Normal output, the XML output, and the Grepable output saved as base.nmap, base.xml, and base.gnmap. It’s like turning on -oN, -oX, and -oG together, instead of running them separately. It isn’t limited to the console—the outputs go into files. It isn’t deprecated. One practical detail is that you do need to supply a basename so Nmap knows what to name the files, but the defining feature is that all three formats are produced in one command.
