Answer options

A: It is a sample of dbzone’s physical memory usage taken every hour over a 24-hour period.Only the top 10 samplings of peak memory usage are displayed. All other utilization data is eliminated.

B: It is a sample of dbzone’s CPU, virtual memory, and networking utilization.Physical memory is executed from the report.The sampling is taken every 10 minutes over a 24-hour period and peak utilization id displayed each hour.

C: It is a sample of dbzone’s CPU, virtual memory, and networking utilization.Physical memory is executed from the report.The sampling is taken every 10 minutes over a 24-hour period and displayed each hour.

D: It is a sample of dbzone’s physical memory usage taken every 10 seconds and 24-hour period.Only peak virtual memory usage and CPU utilization are displayed each hour.All other Utilization data is eliminated. Correct answer

Explanation

* (Not A, B, C): interval (here 10 seconds): Specifies the length in seconds to pause between each interval report.
* duration (here 24 h)
* -R report[, report] (here high) Print a summary report. High Print a summary report detailing the highest usage of each resource and zone during any interval of the zonestat utility invocation.
Note: The zonestat utility reports on the cpu, memory, and resource control utilization of the currently running zones. Each zone's utilization is reported both as a percentage of system resources and the zone's configured limits. The zonestat utility prints a series of interval reports at the specified interval. It optionally also prints one or more summary reports at a specified interval. The default output is a summary of cpu, physical, and virtual memory utilization. The -r option can be used to choose detailed output for specific resources.
