A logistics company stores daily vehicle route telemetry reports in an Amazon S3 bucket. The average file size of each report is $8\text{ MB}$ . These reports are accessed frequently for real-time tracking and optimization during the first $14$ days after upload. After $14$ days, the reports are rarely accessed, but the company must retain them for a total of $90$ days for monthly compliance auditing. After $90$ days, the reports must be permanently deleted.

Which two actions should the company take to meet these requirements in the most cost-effective manner?

Configure an S3 Lifecycle rule to transition the reports from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) after $14$ days.Answer
Configure an S3 Lifecycle rule to expire the reports after $90$ days.Answer
C
Configure an S3 Lifecycle rule to transition the reports to S3 Standard-Infrequent Access (S3 Standard-IA) after $5$ days.
D
Configure an S3 Lifecycle rule to transition the reports to Amazon S3 Glacier Flexible Retrieval after $14$ days and expire them after $90$ days.
E
Configure an S3 Lifecycle rule to transition the reports to S3 Standard-Infrequent Access (S3 Standard-IA) after $14$ days and expire them after $25$ days.

Answer

The company should configure an S3 Lifecycle rule to transition the reports from S3 Standard to S3 Standard-Infrequent Access after 14 days, and configure another lifecycle rule to expire the reports after 90 days.

Transitioning reports to S3 Standard-IA after 14 days aligns with the access patterns and object size requirements, while staying in the tier for 76 days avoids any minimum storage duration penalties. Expiring the reports after 90 days fulfills the compliance requirement while minimizing storage costs.

Step-by-Step Solution

Analyze access patterns and object sizes to select the correct storage class transition timing.

Since the reports are frequently accessed for the first 14 days, they must remain in S3 Standard during this period. After 14 days, they are rarely accessed and have an average size of 8 MB (larger than the 128 KB minimum size threshold), making them ideal candidates for S3 Standard-Infrequent Access (S3 Standard-IA).

S3 Standard-IA is cost-optimized for infrequently accessed data that requires rapid access when needed, but it charges a retrieval fee and has a minimum object size limit of 128 KB.

Evaluate the storage duration in S3 Standard-IA against the minimum storage duration requirement.

The objects will transition to S3 Standard-IA on day 14 and be deleted on day 90, meaning they will spend 76 days in S3 Standard-IA. This satisfies the 30-day minimum storage duration requirement for S3 Standard-IA without incurring early deletion penalties.

S3 Standard-IA requires a minimum storage duration of 30 days. Deleting or transitioning objects before this period results in charges for the remaining days.

Select the correct expiration rule to automate the final lifecycle stage.

Create an S3 Lifecycle expiration action to delete the reports after 90 days.

The scenario requires that reports be permanently deleted after 90 days to minimize storage costs once the retention compliance period has ended.
