An online company wants to conduct real-time sentiment analysis about its products from its social media channels using SQL.
Which of the following solutions has the LOWEST cost and operational burden?
A. Configure the input stream using Amazon Kinesis Data Streams. Use Amazon Kinesis Data Analytics to write SQL queries against the stream.
B. Set up a streaming data ingestion application on Amazon EC2 and connect it to a Hadoop cluster for data processing. Send the output to Amazon S3 and use Amazon Athena to analyze the data.
C. Set up streaming data ingestion application on Amazon EC2 and send the output to Amazon S3 using Kinesis Data Firehose. Use Athena to analyze the data.
D. Configure the input stream using Amazon Kinesis Data Streams. Use Amazon Kinesis Data Firehose to send data to an Amazon Redshift cluster, and then query directly against Amazon Redshift

質問 6：
A Solutions Architect is designing a disaster recovery (DR) environment in a separate AWS region from an application's primary workload. The application uses a multi-tier architecture, and only the RDS instance will have frequent changes. The application installation process takes 60 minutes on average. The disaster recovery plan must have an RPO of less than 90 minutes and an RTO of less than 30 minutes.
Which of the following would enable the Solutions Architect to meet these requirements? (Select TWO.)
A. A cross-region Amazon EC2 Amazon Machine Image (AMI) copy
B. Amazon S3 cross-region replication of application-tier installers
C. Inter-region VPC peering between the primary workload VPC and the DR VPC
D. An Aurora instance as the primary database with a read replica in the DR region
E. Amazon Cloud Watch Events in the primary region that trigger the failover to the DR region
