A microservices application is experiencing high latency. The architecture consists of an API Gateway, an Authentication service, a Business Logic service, and a Database. You need to identify exactly which service is causing the bottleneck. Which TWO GCP observability tools should you use? (Select TWO)

To debug latency in a distributed microservices architecture, you use Cloud Trace. It provides a waterfall graph showing the lifecycle of a request across all services, instantly highlighting which service is the bottleneck. Once the slow service is identified, you use Cloud Profiler to continuously analyze the performance of the code (CPU/RAM) within that service to find the exact function causing the delay.
