Google Cloud Professional Cloud Database Engineer — Question 21

Your company uses Bigtable for a user-facing application that displays a low-latency real-time dashboard. You need to recommend the optimal storage type for this read-intensive database. What should you do?

Answer options

• A. Recommend solid-state drives (SSD).
• B. Recommend splitting the Bigtable instance into two instances in order to load balance the concurrent reads.
• C. Recommend hard disk drives (HDD).
• D. Recommend mixed storage types.

Correct answer: A

Explanation

The correct answer is A because solid-state drives (SSD) provide much faster read access times compared to other storage options, which is crucial for low-latency applications. Options B and D may improve performance but do not directly address the need for faster read times as SSDs do. Option C, hard disk drives (HDD), are generally slower than SSDs and would not be optimal for a read-intensive application.
