Google Professional Cloud Developer Question 32
Single answerGoogle Cloud PlatformYou are developing a web application hosted on Google Cloud that requires user session management. The application is expected to handle high traffic and must efficiently manage user sessions while ensuring scalability and low latency. Which solution should you implement?
- A
Use Google Cloud Memorystore (Redis) to store user session data.
- B
Store user session data in Firestore as documents.
- C
Store user session data in a local in-memory cache on the application server.
- D
Use Google Cloud Pub/Sub to manage user session data.
Show answer and explanation
Correct answer: A
Explanation
For user session management in a high-traffic application, it is crucial to use a solution that provides low-latency access and is scalable. Google Cloud Memorystore (Redis) is designed to handle these requirements, making it the ideal choice for managing user sessions efficiently. Other options like Firestore and Pub/Sub are not optimized for this use case, and local in-memory caching would not work for scalable multi-instance architectures.
- A. Correct.
Google Cloud Memorystore (Redis) is an excellent choice for storing session data because it is an in-memory data store that provides low-latency access and is highly scalable. It is optimized for session management tasks.
- B. Incorrect.
While Firestore is a scalable NoSQL database, it is not optimized for low-latency session management compared to an in-memory solution like Memorystore.
- C. Incorrect.
Storing session data in a local in-memory cache on the application server is not scalable for high traffic applications because the session data would not be shared across multiple instances of the application.
- D. Incorrect.
Google Cloud Pub/Sub is a messaging service designed for asynchronous messaging and event-driven architectures, not for session management.
