NEW QUESTION 5

You have an outage in your Compute Engine managed instance group: all instance keep restarting after 5 seconds. You have a health check configured, but autoscaling is disabled. Your colleague, who is a Linux expert, offered to look into the issue. You need to make sure that he can access the VMs. What should you do?

• A. Grant your colleague the IAM role of project Viewer
• B. Perform a rolling restart on the instance group
• C. Disable the health check for the instance grou
• D. Add his SSH key to the project-wide SSH keys
• E. Disable autoscaling for the instance grou
• F. Add his SSH key to the project-wide SSH Keys

Answer: C

Explanation:
https://cloud.google.com/compute/docs/instance-groups/autohealing-instances-in-migs
Health checks used for autohealing should be conservative so they don't preemptively delete and recreate your instances. When an autohealer health check is too aggressive, the autohealer might mistake busy instances for failed instances and unnecessarily restart them, reducing availability

Explanation:
Export the logs to Google Cloud Storage bucket - Archive Storage, as it will not be used for 1 year, price for which is $0.004 per GB per Month. The price for long term storage in BigQuery is $0.01 per GB per Month (250% more). Also for analysis purpose, whenever Auditors are there(once per year), you can use BigQuery and use GCS bucket as external data source. BigQuery supports querying Cloud Storage data from these storage classes:
