   A server administrator is troubleshooting intermittent performance issues. The administrator has been using vmstat to collect data every 5 seconds, but the issues occur sporadically and may not be captured. What is the most effective way to ensure the data needed for analysis is collected?

   • AIncrease the vmstat sampling interval to every 1 second.
   • BRun top in batch mode and save the output to a file.
   • CUse free to monitor memory usage continuously.
   • DUse sar with a scheduled collection interval to capture historical data continuously.

   A company runs a critical application on a server that experiences periodic slowdowns. The administrator has been collecting sar data for several months. The slowdowns occur at random times, and the administrator needs to determine if they are caused by CPU saturation, memory pressure, or disk I/O bottlenecks. Which approach would best identify the root cause?

   • ACheck the system logs for error messages.
   • BRun top continuously and watch for slowdowns in real time.
   • CUse vmstat to take a single snapshot of system performance.
   • DReview sar reports for the time periods when slowdowns occurred and compare resource utilization metrics.
