Topic 7 Question 5
Your development teams release new versions of games running on Google Kubernetes Engine (GKE) daily. You want to create service level indicators (SLIs) to evaluate the quality of the new versions from the user's perspective. What should you do?
Create CPU Utilization and Request Latency as service level indicators.
Create GKE CPU Utilization and Memory Utilization as service level indicators.
Create Request Latency and Error Rate as service level indicators.
Create Server Uptime and Error Rate as service level indicators.

IMHO c) is the correct answer, not a). Reason is, that we have to take the users perspective (according to the given question and also to understand what the user expects from us). The question might be whether to choose c) or d). Considering that our requirement is to minimize the latency, we have to choose c) - that means we are striving for no downtime of the service.

👍 8MamthaSJ2021/07/07Answer is C. End users don't care or need to know about server uptime, CPU or memory. End- users care about their user experience.
Service Level Indicators (SLI) is the metrics for the level of service provided to end users. Real numbers of the performance.
Example: request latency to be less than 500ms in the last 15 minutes with a 95% percentile.Service Level objective: Target level for the reliability of your service. Example: SLI to be met 99% of the time.
SLA - the agreement that you make with the end users.
