How can you save Nmap output in multiple formats in a single command, and which formats does -oA produce?

• A. -oA <basename> to save Normal (-oN), XML (-oX), and Grepable (-oG) outputs simultaneously.
• B. -oA to save only XML output.
• C. -oA to save outputs to a database.
• D. -oA to save to a single concatenated file.

Answer: (A)

Using the -oA option with a basename saves all three output formats in one go. It expands to running -oN, -oX, and -oG together, giving you a normal (human-readable) output, an XML file, and a grepable text file. The resulting files will be named using the provided basename with extensions: basename.nmap, basename.xml, and basename.gnmap. This is the convenient way to keep all common formats available from a single command. If you only need one format, you’d use the specific option alone, rather than -oA.
