Optimize an Azure Cosmos DB solution

Question

Drag and Drop Question You are designing three apps named App1, App2, and App3. Each app will use a separate Azure Cosmos DB for NoSQL account. The apps have the following consistency requirements:

  • App1: Reads must always return the most recent committed version of

an item, where the commit occurred during the same session.

  • App2: Reads must always return the most recent committed version of

an item, even if the commit occurred during another session.

  • App3: Write latency must be minimized and data staleness can be

tolerated. You need to recommend a default consistency level for each Azure Cosmos DB for NoSQL account. The solution must minimize concurrency. What should you recommend for the account of each app? To answer, drag the appropriate consistency levels to the correct apps. Each consistency level may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point. Answer:
