Exam Professional Cloud Architect topic 1 question 24 discussion

D is correct !

D. Instrument your application with Stackdriver Trace in order to break down the request latencies at each microservice Stackdriver Trace is a distributed tracing system that allows you to understand the relationships between requests and the various microservices that they touch as they pass through your application. By instrumenting your application with Stackdriver Trace, you can get a detailed breakdown of the latencies at each microservice, which can help you identify which service is taking the longest in those cases where a small number of API requests take a very long time. Setting timeouts on your application or sending custom metrics to Stackdriver Monitoring may not provide the level of detail that you need to identify the specific service that is causing the latency issues. Looking for insights in Stackdriver Monitoring may also not provide the necessary level of detail, as it may not show the individual latencies at each microservice.

1. Distributed Tracing: Stackdriver Trace (now called Cloud Trace) is specifically designed to analyze the performance of requests as they travel through multiple services in a microservices architecture. It helps you pinpoint exactly where latency is occurring. 2. Detailed Breakdown: Cloud Trace will provide a detailed breakdown of how long each microservice takes to process the request, allowing you to identify the bottleneck quickly. 3. Visualization: Cloud Trace provides visualizations like flame graphs and waterfall diagrams that make it easy to see the flow of the request and identify slow services.

Choose D

This question is not updated. It will be refered as Cloud Trace as part of Google Cloud Operation suite

This question is not updated. Stackdriver is now called "Google Cloud operations"

Trace is a signal that can be used to follow the program's data and flow, including the duration of the program's components.

D should be correct, the headline in GC trace documentation says it all: "Cloud Trace is a distributed tracing system for Google Cloud that collects latency data from applications and displays it in near real-time in the Google Cloud Console."

D is the correct answer

Why not C?

D is the correct answer

Stacdrive Trace would trace the APIs and helps to identify the bottleneck

D is correct trace would report to the latency

D is correct trace would report to the latency

D. Instrument your application with Stackdriver Trace in order to break down the request latencies at each microservice

Instrument your application with Stackdriver Trace in order to break down the request latencies at each microservice

D is correct !
