NEW QUESTION # 83
Your company experiences bugs, outages, and slowness in its production systems. Developers use the production environment for new feature development and bug fixes. Configuration and experiments are done in the production environment, causing outages for users. Testers use the production environment for load testing, which often slows the production systems. You need to redesign the environment to reduce the number of bugs and outages in production and to enable testers to toad test new features. What should you do?

A. Create an automated testing script in production to detect failures as soon as they occur.
B. Create a development environment with smaller server capacity and give access only to developers and testers.
C. Create a development environment for writing code and a test environment for configurations, experiments, and load testing.
D. Secure the production environment to ensure that developers can't change it and set up one controlled update per year.

Answer: A

NEW QUESTION # 84
You are using Stackdriver to monitor applications hosted on Google Cloud Platform (GCP). You recently deployed a new application, but its logs are not appearing on the Stackdriver dashboard.
You need to troubleshoot the issue. What should you do?

A. Confirm that port 25 has been opened in the firewall to allow messages through to Stackdriver.
B. Confirm that your account has the proper permissions to use the Stackdriver dashboard.
C. Confirm that the Stackdriver agent has been installed in the hosting virtual machine.
D. Confirm that the application is using the required client library and the service account key has proper permissions.

Answer: C

NEW QUESTION # 85
You are designing a new multi-tenant Google Kubernetes Engine (GKE) cluster for a customer. Your customer is concerned with the risks associated with long-lived credentials use. The customer requires that each GKE workload has the minimum Identity and Access Management (IAM) permissions set following the principle of least privilege (PoLP). You need to design an IAM impersonation solution while following Google-recommended practices. What should you do?

A. Create a Google service account.
Create a service account key for the Google service account.
Create a Kubernetes secret with a service account key.
Ensure that workload mounts the secret and set the GOOGLE_APPLICATION_CREDENTIALS environment variable to point at the mount path.
Repeat for each workload.
B. Create a Google service account.
Create a Kubernetes service account in a Workload Identity-enabled cluster.
Link the Google service account with the Kubernetes service account by using the roles/iam.
workloadIdentityUser role and iam.gke.io/gcp-service-account annotation.
Map the Kubernetes service account to the workload.
Repeat for each workload.
C. Create a Google service account.
Create a node pool, and set the Google service account as the default identity.
Ensure that workloads can only run on the designated node pool by using node selectors, taints, and tolerations.
Repeat for each workload.
D. Create a Google service account.
Create a node pool without taints, and set the Google service account as the default identity.
Grant IAM permissions to the Google service account.

Answer: B

Explanation:
Google Workload Identity is the recommended method to allow GKE workloads to securely access Google Cloud APIs using short-lived credentials without managing keys.
"Workload Identity is the recommended way to access Google Cloud services from GKE. It replaces the older method of using service account keys."
- Workload Identity Overview
"You can configure a Kubernetes service account to impersonate a Google Cloud service account by granting the roles/iam.workloadIdentityUser role and using the iam.gke.io/gcp-service-account annotation."
- Configure Workload Identity
This satisfies the customer's requirement for PoLP and avoids long-lived keys.

NEW QUESTION # 86
Your application's performance in Google Cloud has degraded since the last release. You suspect that downstream dependencies might be causing some requests to take longer to complete. You need to investigate the issue with your application to determine the cause. What should you do?

A. Configure Google Cloud Managed Service for Prometheus in your application.
B. Configure Cloud Trace in your application.
C. Configure Cloud Profiler in your application.
D. Configure Error Reporting in your application.

Answer: B

Explanation:
Comprehensive and Detailed Explanation:
Google Cloud Trace is specifically designed to analyze request latency and identify performance bottlenecks across services. Since the issue is related to slow performance after a new release, the best approach is to use Cloud Trace to:
Visualize request latency across services
Pinpoint slow dependencies affecting response time
Analyze performance trends over time
#Why not other options?
B (Error Reporting)## Focuses on uncaught exceptions and crashes, not latency issues.
C (Cloud Profiler)## Helps with CPU and memory analysis, not request tracing.
D (Prometheus for Cloud Monitoring)## Useful for metrics collection, but not ideal for debugging specific request latency issues.
