Which of the following would be a reasonable response to his request?

After you recommend Amazon Redshift to a client as an alternative solution to paying data warehouses to analyze his data, your client asks you to explain why you are recommending Redshift.

Which of the following would be a reasonable response to his request?
A . It has high performance at scale as data and query complexity grows.
B . It prevents reporting and analytic processing from interfering with the performance of OLTP workloads.
C . You don’t have the administrative burden of running your own data warehouse and dealing with setup, durability, monitoring, scaling, and patching.
D . All answers listed are a reasonable response to his question

Answer: D

Explanation:

Amazon Redshift delivers fast query performance by using columnar storage technology to improve I/O efficiency and parallelizing queries across multiple nodes. Redshift uses standard PostgreSQL JDBC and ODBC drivers, allowing you to use a wide range of familiar SQL clients. Data load speed scales linearly with cluster size, with integrations to Amazon S3, Amazon DynamoDB, Amazon ElasticMapReduce, Amazon Kinesis or any SSH-enabled host.

AWS recommends Amazon Redshift for customers who have a combination of needs, such as:

High performance at scale as data and query complexity grows

Desire to prevent reporting and analytic processing from interfering with the performance of OLTP workloads

Large volumes of structured data to persist and query using standard SQL and existing BI tools

Desire to the administrative burden of running one’s own data warehouse and dealing with setup, durability, monitoring, scaling and patching
