SRE and DevOps fundamentals sample question with answer 99

Question:
Let’s say your colleagues are debating whether to employ synthetic or real user monitoring. How is real user monitoring different than synthetic checks?

1. Real user monitoring monitors the speed of the application. Synthetic checks make sure the hardware is functional
2. Synthetic checks analyze security flaws in the application in real time whereas real user monitoring observers the system from the viewpoint of a hacker
3. Synthetic performance monitoring analyzes software performance in real world scenarios. Real user monitoring observes just the performance of the user, not the system
4. Real user monitoring records all the actual end user’s engagement with the web application. Synthetic checks simulate how a user might interact with the application

Answer:
D - is the correct answer
