Parson Fortunes Ltd is an Asian-based department store operator with an extensive network of 131 stores, spanning approximately 4.1 million m2 of retail space across cities in India, China, Vietnam, Indonesia and Myanmar.
Parson has large assets of data around 20 TB’s of structured data and 45 TB of unstructured data and is planning to host their data warehouse on AWS and unstructured data storage on S3. Parson IT team is well aware of the scalability, performance of AWS services capabilities. Parson is currently using running their DWH, on-premises on Teradata and is concerned on the overall costs of the DWH on AWS. They want to initially migrate the platform onto AWS to address their performance intensive workloads in place. Initially, they want to keep a fraction (15%) of the structured data in a data warehouse storage and gradually expand to real-time data integration and data driven analytics as a road map in the next 6 months Currently the number of users accessing the application would be around 100. What is your suggestion? 

Answer options:

A.Launch Redshift cluster with node types DS2.xlarge to fulfill the requirements
B.Launch Redshift cluster with node types DS2.8xlarge to fulfill the requirements
C.Launch Redshift cluster with node types DC2.large to fulfill the requirements
D.Launch Redshift cluster with node types DC2.8xlarge to fulfill the requirements

Answer : C
Option A is incorrect -DS2 node types are optimized for large data workloads and use hard disk drive (HDD) storage. This is not the requirement

Option B is incorrect -DS2 node types are optimized for large data workloads and use hard disk drive (HDD) storage. This is not the requirement
https://docs.aws.amazon.com/redshift/latest/mgmt/working-with-clusters.html#rs-about-clusters-and- nodes
Option C is correct -DC2 node types are optimized for performance-intensive workloads. DC2.large fulfills the requirements since it provides massive parallel processing using multiple nodes. Based on the amount of data loaded, this is the right option
https://docs.aws.amazon.com/redshift/latest/mgmt/working-with-clusters.html#rs-about-clusters-and- nodes
Option D is incorrect -DC2 node types are optimized for performance-intensive workloads. DC2.8xlarge does not fulfill the requirements since it can provide massive parallel processing using multiple nodes. Since cost and performance is also a concern, this is not the right option.
