SAP Basis Interview Questions

61 - The CPU metrics, %user, %system, and %idle, are global CPU metrics. The %user expresses the percentage of user processes in user mode, the %system expresses the percentage of processes in kernel mode (system calls), and %idle expresses the percentage of non-CPU activity.

A high %system CPU utilization value as shown in this transaction ST06 screen always expresses system resource problems.

Which of the following is a symptom of high %system CPU utilization?
Click on the button next to the right answer.
A. Memory management
B. I/O management
C. Heavy IPC system call rate, process creation, heavy network traffic

62 - Based upon the information in the indicated area of this Operating System Performance Monitor screen (ST06), what does the Load Average value express?
Click on the button next to the right answer.
A. It is a metric that depends on the percentage of the CPU, I/O and LAN resources being utilized.
B. The 1, 5, and 15 minute averages of the count of processes in the run queue of the operating system.
C. The load average value shows the 1, 5, 15 minute averages of the system swapping activity.
D. The load average value shows the 1, 5, 15 minute averages of the operating system uptime.

63 - Which of the following statements describes the average response time as indicated in this Workload Analysis screen?
Click on the button next to the right answer.
A. Average response time is equal to or less than the sum of CPU time, plus wait time, plus load time, plus database request time.
B. Average response time is equal to or less than the CPU time.
C. Average response time is equal to the sum of CPU time, plus wait time, plus load time, plus database request time, plus time in the frontend process.


64 - Based upon the information in the indicated area of the Workload Analysis screen, which of the following statements is true about Average Wait Time?
Click on the button next to the right answer.
A. Average Wait Time is normally 80% of the average response time.
B. Average Wait Time is normally 50% of the average response time.
C. Average Wait Time is normally less than 5% of the average response time.
65 - This Workload Analysis screen shows an example of poor response time caused from a high average wait time. Which of the following statements explains why the average wait time could be so high?
Click on the button next to the right answer.
A. R/3 programs are waiting a long time to get free workprocesses because system resources are limited.
B. R/3 programs are staying a long time inside of workprocesses because they are waiting for internal R/3 System events.
C. R/3 programs are waiting a long time to get free workprocesses because the R/3 programs are running with low priorities.

66 - Based upon the information indicated in area 1 and 2 of this Operating System Monitor screen, which of the following is true?
Click on the button next to the right answer.
A. System CPU resources are not sufficient. A wait situation is possible when many processes are requesting CPU resources.
B. CPU resources are adequate. No performance problems will be encountered.
C. CPU resources are adequate, but performance problems will be encountered because of wait situations sharing the resources.

67 - Based upon the information in areas 1 - 3 of this R/3 System Monitoring screen, which of the following statements is true?
Click on the button next to the right answer.
A. The "load" program consumes much of the available CPU resources.
B. The "load" program consumes much of the available I/O resources.
C. The "load" program cannot be considered a performance degradation factor.

68 - This performance Analysis screen shows a case of excessive object swapping even though there is apparently enough free space in the Program Buffer.

Based upon the information indicated, which of the following statements explains why there is so much swapping?
Click on the button next to the right answer.
A. The indication of object swapping is false and does not express the current situation.
B. There is enough free space but not enough directory entries.
C. The available free space is fragmented and the fragments are not big enough to hold the new programs.
