You have an Azure Cosmos DB account named Account1 that uses the SQL APL Account1 contains a collection named Coll1.
You have an Apache Spark cluster in Azure HDInsight. The duster is located in the same Azure region as Account1.
You configure a Spark to Cosmos DB connector to access Coll1.
You successfully use the following code to run non-aggregate queries from within a Spark session by using the connector (Line numbers are included for reference only.)
01 query= client QueryDocuments (
02 collLink, querystr,
03 options=
04 {
05 'enablecrossPartitionQuery': True
06 },
07 partition_key-None)
08 df = spark.createDataFrame(list(query))
You need to modify the code to ensure that you can run couNT aggregate quenes.

You have an Azure Cosmos DB account that uses the SQL API. The account has a limit of 2,500 request units per second (RU/s). The default consistency level is set to Eventual.
You discover that you frequently exceed the Ru/s limit.
You need to recommend strategies to reduce the number of request units (RUs) consumed.
Which two possible strategies can you recommend to achieve this goal? Each correct answer presents a complete solution. NOTE. Each correct selection is worth one point.

You have an Azure Cosmos DB account named Account1. Account1 contains a database named DB1. DB1 contains a collection named Coll1 Account has a write region of East US and a read region of West US. Coll1 contains 500,000 documents that are 1 KB each.
You have two applications named App1 and App2 that read documents from Coll1 in the East US region at a steady rate of 1,000 request units per second (RU/s). Both applications consistently throw an exception that has the 429 HTTP status code.
You need to recommend a solution to minimize the number of exceptions. The solution must minimize costs.
