Practice Test 2 | Google Cloud Certified Professional Cloud DevOps Engineer | Dumps | Mock Test
You are on a cross-functional team of SREs and product developers managing an application that needs to be deployed to production. Metrics for measuring reliability and performance of the application have been agreed on. There is a need to decide the frequency of releasing new changes.
Following Google’s SRE practice, what measure should be used to control this?
A. The Service Level Indicators (SLI) measurements can be used to control the frequency of new releases to production
B. The Service Level Agreements (SLA) should be used to control the frequency of new releases to production
C. The Service Level Objectives (SLO) measurements should be used to control the frequency of new releases to production
D. The Error Budget should be used to control the frequency of new releases to production
Correct Answer: D
- Options A, B and C are incorrect. The decision on how frequent to push new changes is based on the amount of error budget left.
- Option D is CORRECT. The amount of error budget is used to determine how frequent new releases should be pushed to production, so the application’s reliability does not fall below the agreed SLO/SLA.
