QUESTION:
To ensure the reliability of the new ingestion pipeline, the operations team wants to implement SRE practices. How should they measure the performance of the ingestion API?
Answer options:
Measure the CPU utilization of the underlying VMs and alert if it exceeds 80%.
Define Service Level Indicators (SLIs) for API latency and error rate, and set a Service Level Objective (SLO) of 99.9%.
Create a Service Level Agreement (SLA) with the development team to guarantee zero downtime.
Use Cloud Profiler to continuously monitor the code execution time.
