Topic 9 Question 50
2 つ選択Which statements about application load testing are true?
You should test at the maximum load that you expect to encounter.
You should test at 50% more than the maximum load that you expect to encounter.
It is not necessary to test sudden increases in traffic since GCP scales seamlessly.
Your load tests should include testing sudden increases in traffic.
解説
Your tests should be designed to simulate real world traffic as closely as possible. You should test at the maximum load that you expect to encounter. In addition, some applications will get a sudden increase in load, and you will need to predict the rate of increase. If you are expecting spikey load, you should also test how your application performs when traffic suddenly increases. Although GCP services scale quickly, they do not scale instantaneously, which is why you should test sudden increases in traffic.

why not B AND D, you cant test exact load
👍 11Macdon2020/06/10Answer A,D is appropriate. Google Documentation says that

👍 8a660302020/10/26The text referred is just a community's document, not the official Google's documentation. Anyone who has worked in real projects knows you have to go beyond what you expect in case you understimate the demand. Maybe A,D are the righ answer for the exam, but in the real world B,D would be what you boss/customer expect from you (IMHO).
