Should be D definitely

D is correct.

A is not correct because local memory is lost on process termination, so you would lose the cart information. B is not correct because accessing a Cloud Storage bucket is slow and expensive for session information. This is not a Google Cloud best practice. C is not correct because BigQuery wouldn't be able to handle the frequent updates made to carts and sessions. D is correct because Memorystore is fast and a standard solution to store session information, and Firestore is ideal for small structured data such as a shopping cart. The user will be mapped to the shopping cart with a new session, if required.

Answer is D When storing session and shopping cart information for an ecommerce platform, it's important to consider scalability, reliability, and security. One solution that follows Google-recommended best practices would be to use Memorystore for Redis or Memorystore for Memcached to store session information and Firestore to store shopping cart information. Memorystore can store session information and easily handle a large number of concurrent connections, which is crucial for an ecommerce platform where users are logged in and adding items to their shopping cart frequently. Firestore can easily handle large amounts of semi-structured data, such as a shopping cart's item. Firestore is also a scalable and reliable solution, and it supports automatic scaling and replication. By separating the session information and shopping cart information into different services, you can also increase security and avoid any potential data breaches. Using different services will also allows you to scale them independently.

D is the answer.
