Google Professional Cloud Developer Question 221
Single answerGoogle Cloud PlatformYour development team uses Google Cloud Workstations to standardize their development environments. One developer reports an error while trying to connect to a workstation instance. Upon investigation, you notice that the instance is running but the developer cannot access it. What should you check first to resolve the issue?
- A
Verify that the developer has been added to the correct IAM role for accessing the Cloud Workstations.
- B
Check if the Compute Engine API is enabled for the project hosting the workstation.
- C
Ensure that the workstation instance's firewall rules allow SSH traffic from the developer's IP address.
- D
Restart the workstation instance to resolve potential connectivity issues.
Show answer and explanation
Correct answer: A
Explanation
When troubleshooting access issues with Google Cloud Workstations, the first step is to verify that the user has the necessary IAM permissions. Without proper roles like 'Workstations User', the user cannot connect to the workstation even if it is running. Other potential issues, such as APIs or firewall rules, are less likely to be the problem in this scenario since the workstation instance is already operational.
- A. Correct.
This is the correct answer. IAM roles control access to Google Cloud resources, including Cloud Workstations. If the developer does not have the right permissions, they will be unable to connect even if the workstation is running.
- B. Incorrect.
While the Compute Engine API is necessary for managing workstation instances, it being disabled would prevent the instance from running at all. This is not the most likely issue in this case since the instance is already running.
- C. Incorrect.
Firewall rules for Cloud Workstations are generally managed automatically, and SSH access is not the mechanism used for connecting to Cloud Workstations. Therefore, this is not relevant to the issue described.
- D. Incorrect.
Restarting the instance can resolve some issues, but it is not the first step to troubleshoot an access problem. The root cause should be investigated before taking such measures.
