Exam DP-420 topic 1 question 21 discussion

In such case user would see the same data from the different device, because session would be the same

D and E are correct answers

BC is the right answer. Please update. To ensure that users see the same item values consistently when browsing from different devices while not affecting the other applications, you should perform the following two actions: B. Associate a session token to the device: You should associate a session token with each user's device. This means that each device used by a user will have its own session token. This ensures that the same user, when browsing from different devices, maintains a consistent session with the Azure Cosmos DB. It allows users to see consistent item values across their devices. C. Use implicit session management when performing read requests: When performing read requests from the new application, use implicit session management. Implicit session management means that the SDK you are using to interact with Azure Cosmos DB automatically manages the session token for you. It keeps track of the session token associated with the device, ensuring that each read operation uses the correct session token. This ensures consistency for the user's session across devices. Here's an additional explanation of the options you should not select:

D and E are correct. We login to device with a user-id so session token should be associated with user not device.

B. By associating a session token with each device, you ensure that reads from the same device maintain consistent and up-to-date results. C. Implicit session management involves utilizing Cosmos DB's built-in session handling capabilities.

Selected Answer: BC

B. Associate a session token to the device. C. Use implicit session management when performing read requests.

B. Associate a session token to the device. E. Associate a session token to the user account. By associating a session token to each device and user account, you can maintain consistency across multiple devices used by the same user. The session token represents a logical session and helps track the user's interaction with the data. This ensures that when the user switches between devices, they continue to see the same consistent data.

By associating a session token to the device and providing a stored session token when performing read requests, the application ensures that the user sees the same item values consistently when browsing from different devices.

B. Associate a session token to the device: When a user logs in to the application from a device, a session token should be generated and associated with the device. This will ensure that subsequent requests from the same device are routed to the same backend server that served the first request, and the user will see consistent item values. C. Use implicit session management when performing read requests: When performing read requests, the application should use implicit session management. This means that the SDK will automatically manage the session token, and the user will continue to see consistent item values regardless of which backend server serves the request.
