CKA study material · question 940 of 1000

A component is started with -v=0. What is logged?

  1. Nothing at all
  2. Everything, since 0 disables filtering
  3. Only debug-level messages
  4. Only critical events
Show the answer

Answer: D. Only critical events

The -v flag raises verbosity as it rises: 0 logs only critical events, and higher values progressively add less severe ones.
