Google Cloud Professional Cloud Architect — Question 143

Your company has an application deployed on Anthos clusters (formerly Anthos GKE) that is running multiple microservices. The cluster has both Anthos Service
Mesh and Anthos Config Management configured. End users inform you that the application is responding very slowly. You want to identify the microservice that is causing the delay. What should you do?

Answer options

• A. Use the Service Mesh visualization in the Cloud Console to inspect the telemetry between the microservices.
• B. Use Anthos Config Management to create a ClusterSelector selecting the relevant cluster. On the Google Cloud Console page for Google Kubernetes Engine, view the Workloads and filter on the cluster. Inspect the configurations of the filtered workloads.
• C. Use Anthos Config Management to create a namespaceSelector selecting the relevant cluster namespace. On the Google Cloud Console page for Google Kubernetes Engine, visit the workloads and filter on the namespace. Inspect the configurations of the filtered workloads.
• D. Reinstall istio using the default istio profile in order to collect request latency. Evaluate the telemetry between the microservices in the Cloud Console.

Correct answer: A

Explanation

Option A is correct because it directly utilizes the Service Mesh visualization to analyze telemetry data, which is crucial for identifying performance issues between microservices. The other options involve filtering and inspecting configurations, which may not provide the immediate insight needed to diagnose latency problems.
