• D1. Export VM utilization logs from Stackdriver to a Cloud Storage bucket. 2. Enable the Cloud

Explanation

To create an interactive, real-time, and shareable VM utilization dashboard with quarterly aggregation from Stackdriver logs, export the logs to BigQuery and then visualize them using Data Studio.

Common mistakes.

• B. Cloud Pub/Sub is a messaging service for real-time data ingestion and event-driven architectures; it is not a data warehousing solution suitable for historical aggregation and interactive dashboards directly.
• C. Exporting logs from BigQuery to a Cloud Storage bucket would store raw or aggregated data, but Cloud Storage is an object storage service and does not natively provide the interactive dashboarding capabilities needed.
• D. Storing logs directly in a Cloud Storage bucket is good for archival, but it doesn't provide built-in interactive dashboarding or real-time query capabilities for aggregation without further processing.
