Question 255 Topic 6

Your company has an application that is running on multiple instances of Compute Engine. It generates 1 TB per day of logs.
For compliance reasons, the logs need to be kept for at least two years. The logs need to be available for active query for 30
days. After that, they just need to be retained for audit purposes. You want to implement a storage solution that is compliant,
minimizes costs, and follows Google-recommended practices. What should you do?

• A. 1. Install a Cloud Logging agent on all instances. 2. Create a sink to export logs into a regional Cloud Storage bucket. 3. Create an Object Lifecycle rule to move files into a Coldline Cloud Storage bucket after one month. 4. Configure a retention policy at the bucket level using bucket lock.
