sysstat -s 5 describes the behavior of which of the following?

• A. Display the default output every five seconds and terminate after five counts.
• B. Display extended output every five seconds and print a summary after five counts.
• C. Display extended output every five seconds and print a summary upon termination.
• D. Display the default output every five seconds and print a summary upon termination.

Answer: (C)

When you collect stats with sysstat, the interval controls how often a snapshot is taken. Setting the interval to five seconds means you’ll see extended statistics refreshed every five seconds, giving you more detail per moment than the minimal summary lines. The run also yields a final summary when you stop the collection or when it ends, aggregating the data from all the samples you collected. So the description that matches is: you get extended output every five seconds and a summary printed when the session terminates. This aligns with the idea of rich per-interval data being shown regularly, followed by an end-of-run summary. The other options would imply either only default output, or a summary being printed after a fixed number of samples without the normal end-of-run summary behavior.
