Exam Cloud Digital Leader topic 1 question 20 discussion

Bigtable is a key-value and wide-column store, ideal for fast access to structured, semi-structured, or unstructured data. This makes latency-sensitive workloads like personalization a perfect fit for Bigtable. However its distributed counters, high read and write throughput per dollar makes it also a great fit for clickstream and IoT use cases, and even batch analytics for high-performance computing (HPC) applications, including training ML models.

Cloud Bigtable is a fully managed, highly scalable, and high-performance NoSQL database service designed for large-scale applications that require low-latency and high-throughput data storage.

https://cloud.google.com/products/databases?hl=en Refer to above. Option is A

I believe Firestore is a more accurate answer for this question. It is a flexible, scalable NoSQL cloud database for storing and syncing data in real-time. In this case the question states "unstructured data" since its IoT so Firestore is recommended. BigTable can handle it too but the course says it's better suited for ">1 TB of semi-structured or structured data" and it also for analytical work which is not mentioned in this question at all.

D is the correct

D is the answer

D is correct

D is correct

BigTable is correct.

Go for D

If you check https://cloud.google.com/products/databases, then IoT is indicated as a use case for Firestore.

For worldwide, high-speed data storage of a large amount of unstructured data captured from millions of sensor devices, the suitable Google Cloud product for your organization would be Cloud Bigtable. Cloud Bigtable is a fully managed, highly scalable, and high-performance NoSQL database service designed for large-scale applications that require low-latency and high-throughput data storage.

D. Cloud Bigtable

I think the answer is A ( check the document page)

unstructure Data so D

Go for D

Huge Data, Low Access time and Analytics then it should be Big Table D is Answer
