Google Cloud Professional Cloud Database Engineer — Question 10

Your team uses thousands of connected IoT devices to collect device maintenance data for your oil and gas customers in real time. You want to design inspection routines, device repair, and replacement schedules based on insights gathered from the data produced by these devices. You need a managed solution that is highly scalable, supports a multi-cloud strategy, and offers low latency for these IoT devices. What should you do?

Answer options

• A. Use Firestore with Looker.
• B. Use Cloud Spanner with Data Studio.
• C. Use MongoD8 Atlas with Charts.
• D. Use Bigtable with Looker.

Correct answer: D

Explanation

The correct answer is D because Bigtable is designed for high scalability and low latency, making it ideal for handling large volumes of IoT data. Options A, B, and C do not offer the same level of performance or scalability required for real-time IoT data management, making them less suitable for this scenario.
