What is the effect of the -vv option in NetCat?

• A. Be very verbose, printing when connections are made and dropped
• B. Be moderately verbose, printing only when connected
• C. Verbose output is disabled
• D. Logs only errors to the console

Answer: (A)

The double verbose flag is about how much status information NetCat prints. Using the extra verbose level makes NetCat very talkative, showing connection lifecycle events such as when a connection is attempted, when it is established, and when it is closed or dropped. This visibility into the session helps you trace what’s happening during the connection, not just the data transfer. So it’s described as very verbose, printing when connections are made and dropped. It’s not about moderate verbosity, it doesn’t disable output, and it isn’t limited to only errors.
