Google Cloud Professional Cloud Database Engineer — Question 92

Your organization is running a Firestore-backed Firebase app that serves the same top ten news stories on a daily basis to a large global audience. You want to optimize content delivery while decreasing cost and latency. What should you do?

Answer options

• A. Enable serializable isolation in the Firebase app.
• B. Deploy a US multi-region Firestore location.
• C. Build a Firestore bundle, and deploy bundles to Cloud CDN.
• D. Create a Firestore index on the news story date.

Correct answer: C

Explanation

The correct choice is C because building a Firestore bundle and deploying it to Cloud CDN allows for efficient content delivery and reduces latency by caching the content closer to users. Option A does not impact cost or latency, option B may not provide the same level of optimization, and option D focuses on indexing rather than improving content delivery efficiency.
