An administrator is viewing the per-virtual-server CPU statistics in the BIG-IP GUI and sees that VS-A is at 10%, VS-B is at 20%, and VS-C is at 70%. The administrator knows that VS-C handles the most traffic. What is the most appropriate conclusion?

The CPU statistics are incorrect because VS-C should not use more CPU than VS-A

VS-C is definitely causing a performance problem and should be investigated

VS-C's high CPU usage is likely proportional to its traffic load and may not be a problem

VS-A and VS-B are underutilized and should be consolidated

A BIG-IP administrator is analyzing CPU statistics and sees that VS-A is using 40% CPU, VS-B is using 35%, and VS-C is using 25%. The administrator also notices that the system has 4 CPU cores. The administrator needs to determine if any virtual server is monopolizing a specific core. What should the administrator do?

Reboot the system to reset the CPU statistics

Check the per-core CPU statistics to see if any single core is saturated

Conclude that VS-A is the most problematic because it has the highest CPU usage

Assume the statistics are incorrect because the total exceeds 100%

An administrator is using the BIG-IP configuration utility to view CPU statistics for virtual servers. The administrator navigates to Statistics > Module Statistics > Local Traffic > Virtual Servers but does not see a 'CPU Usage' column. What is the most likely reason for this?

The 'CPU Usage' column is hidden by default and must be enabled in the view settings

The administrator is viewing the 'Overview' tab instead of the 'Statistics' tab

The administrator does not have permission to view CPU statistics

The virtual servers are not currently processing any traffic

An administrator is reviewing CPU statistics for virtual servers and notices that VS-A is using 90% of the CPU, while VS-B and VS-C are each using 5%. The administrator needs to determine if VS-A's high CPU usage is a problem. What should the administrator do next?

Check the traffic volume and connection count for VS-A to see if the high CPU usage is proportional to its load

Immediately disable VS-A to stop the high CPU usage

Reboot the BIG-IP system to clear the CPU statistics

Ignore the statistics because CPU usage is not a reliable indicator of performance

Which BIG-IP statistic is used to compare the CPU load generated by different virtual servers on the same device?

Total number of requests per second

CPU usage percentage per virtual server
