Ultimate access to all questions.
Your company has an application running on Google Cloud's Compute Engine that allows users to stream their favorite music. Currently, there are a fixed number of instances handling the workload. Music files are stored in Google Cloud Storage, and the data is streamed directly to users from these storage locations. Recently, users have reported that when trying to play popular songs, they often need to attempt multiple times before succeeding. You need to improve the performance and reliability of the application to ensure a smoother user experience. What should you do?
A
Mount the Cloud Storage bucket using gcsfuse on all backend Compute Engine instances. Serve music files directly from the backend Compute Engine instance.
B
Create a Cloud Filestore NFS volume and attach it to the backend Compute Engine instances. Download popular songs in Cloud Filestore. Serve music files directly from the backend Compute Engine instance.
C
Copy popular songs into CloudSQL as a blob. Update application code to retrieve data from CloudSQL when Cloud Storage is overloaded.
D
Create a managed instance group with Compute Engine instances. Create a global load balancer and configure it with two backends: Managed instance group, Cloud Storage bucket. Enable Cloud CDN on the bucket backend.
