Topic 1 Question 130
2 つ選択You are analyzing Java applications in production. All applications have Cloud Profiler and Cloud Trace installed and configured by default. You want to determine which applications need performance tuning. What should you do?
Examine the wall-clock time and the CPU time of the application. If the difference is substantial increase the CPU resource allocation.
Examine the wall-clock time and the CPU time of the application. If the difference is substantial, increase the memory resource allocation.
Examine the wall-clock time and the CPU time of the application. If the difference is substantial, increase the local disk storage allocation.
Examine the latency time the wall-clock time and the CPU time of the application. If the latency time is slowly burning down the error budget, and the difference between wall-clock time and CPU time is minimal mark the application for optimization.
Examine the heap usage of the application. If the usage is low, mark the application for optimization.

- 正解だと思う選択肢: DE
A conflicts with D hence A gets excluded. B and C don't have direct relation with CPU time/wall time hence excluded either. Answers are D and E.

D for sure, since "If the CPU time is similar to the wall time, then that indicates the code is CPU intensive; almost all the time it takes to run is spent by the CPU. Long-running CPU-intensive blocks of code might be candidates for optimization."
