Google Cloud Professional Cloud Developer PCD — Topic 1 Question 328

Question

Your company manages an application that captures stock data in an internal database. You need to create an API that provides real-time stock data to users. You want to return stock data to users as quickly as possible, and you want your solution to be highly scalable. What should you do?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Create a Memorystore for Redis instance, and use this database to store the most accessed stock data. Query this instance first when user requests are received, and fall back to the internal database. Memorystore provides managed in-memory Redis/Memcached caching to reduce latency and offload databases. This option meets the real-time / low-latency performance requirement.
