Answer: AE

Explanation:

To implement a lambda architecture on Azure, you can combine the following technologies to accelerate real-time big data analytics:

– Azure Cosmos DB, the industry’s first globally distributed, multi-model database service.

– Apache Spark for Azure HDInsight, a processing framework that runs large-scale data analytics applications

– Azure Cosmos DB change feed, which streams new data to the batch layer for HDInsight to process

– The Spark to Azure Cosmos DB Connector

E: You can use Apache Spark to stream data into or out of Apache Kafka on HDInsight using DStreams.
