    you're developing a solution to store data in Azure cosmos DB. the solution must run the following query.


    SELECT * FROM c ORDER BY c.name ASC, c.age asc
    what should you do?

    1. update the indexing mode to consistent

    2. create and configure a synthetic partition key

    3. add a new spatial index to the indexing policy

    4. add a new Composite Index to the indexing policy

    you have a solution that stores data in Azure cosmos DB. you observe high latency and high request unit charges for write operations. you need to reduce the latency and RU charges for write operation. what should you do?



    1. optimize the number of property paths that are indexed

    2. update the indexing mode to consistent

    3. create and configure a synthetic partition key

    4. reduce the provision throughput on container

    5. increase the provision throughput on the container

    you are developing an API that stores data in Azure cosmos DB. the API will be used by mobile app. the API must use the core API and allow millions of reads and writes. which three resources should you consider when determining the request units for the database?



    1. Memory

    2. CPU

    3. network latency

    4. partition size

    5. IOPs

    how to developing a web application. the web application will store data in Azure cosmos DB by using Cassandra API. the stored data has a partition key set to the item ID and a consistency level set to session. you receive a large monthly bill for provisioned request unit in the Azure cosmos DB instance you use for development. you need to reduce the number of RUs consumed by the instance. what should you do?



    1. index additional items in the container

    2. add indexed properties to the container

    3. update the consistency level to strong

    4. remove indexed properties from the container
