sysstat -s 5 outputs 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: (D)

Setting the sampling interval with this option tells sysstat to display statistics every N seconds. When used with 5, it prints the default, concise output at 5-second intervals. It does not switch to extended output just from this flag; extended or more verbose output would require different options. Importantly, statistics are not terminated after a fixed count by default—the tool continues until you stop it, and upon termination it prints a final summary of what was collected. That combination—default output every five seconds and a summary when you stop the run—fits the described behavior.
