AWS Certified Data Analytics – Specialty DAS-C01 – Question122

An online food delivery company wants to optimize its storage costs. The company has been collecting operational data for the last 10 years in a data lake that was built on Amazon S3 by using a Standard storage class. The company does not keep data that is older than 7 years. The data analytics team frequently uses data from the past 6 months for reporting and runs queries on data from the last 2 years about once a month. Data that is more than 2 years old is rarely accessed and is only used for audit purposes.
Which combination of solutions will optimize the company's storage costs? (Choose two.)

A.
Create an S3 Lifecycle configuration rule to transition data that is older than 6 months to the S3 Standard- Infrequent Access (S3 Standard-IA) storage class. Create another S3 Lifecycle configuration rule to transition data that is older than 2 years to the S3 Glacier Deep Archive storage class.
B. Create an S3 Lifecycle configuration rule to transition data that is older than 6 months to the S3 One Zone- Infrequent Access (S3 One Zone-IA) storage class. Create another S3 Lifecycle configuration rule to transition data that is older than 2 years to the S3 Glacier Flexible Retrieval storage class.
