ASSOCIATE-CLOUD-ENGINEER Question #273: Real Exam Question with Answer & Explanation

Question

You are working for a hospital that stores its medical images in an on-premises data room. The hospital wants to use Cloud Storage for archival storage of these images.

• DIn the Google Cloud console, go to Cloud Storage. Upload the relevant images to the appropriate

Explanation

To automate the upload of new medical images from on-premises storage to Cloud Storage for archival, a script utilizing gcloud storage rsync (or gsutil rsync) is the most suitable solution for efficient synchronization.

Common mistakes.

• A. A Pub/Sub topic with a Cloud Storage trigger is designed to react to events within Cloud Storage (e.g., object creation), not to initiate uploads from on-premises to Cloud Storage.
• C. While a Cloud Function can write data to Cloud Storage, triggering it via Pub/Sub would still require an on-premises mechanism to publish messages for each new file, making a direct synchronization tool more appropriate.
• D. Manually uploading files through the Google Cloud console does not meet the requirement for an 'automated process'.
