A fleet management company collects vehicle telematics data. The data is uploaded daily as log files (average size $250\text{ KB}$ ) to an Amazon S3 Standard bucket. The files are accessed frequently during the first $10\text{ days}$ for immediate driver behavior analysis. Between day $10$ and day $40$ , the files are accessed occasionally for monthly reports. After $40\text{ days}$ , the files are rarely accessed but must be retained for an additional $90\text{ days}$ for regulatory auditing, where a retrieval time of $3\text{ to }5\text{ hours}$ is acceptable. After $130\text{ days}$ , the files should be deleted.

Which TWO lifecycle actions should a solutions architect configure to minimize storage costs without incurring minimum storage duration penalties? (Select TWO.)

Configure a lifecycle rule to transition objects from S3 Standard to S3 Standard-IA after $10\text{ days}$ .Answer
Configure a lifecycle rule to transition objects to S3 Glacier Flexible Retrieval after $40\text{ days}$ and expire the objects after $130\text{ days}$ .Answer
C
Configure a lifecycle rule to transition objects from S3 Standard to S3 Standard-IA after $10\text{ days}$ and transition to S3 Glacier Flexible Retrieval after $25\text{ days}$ .
D
Configure a lifecycle rule to transition objects from S3 Standard to S3 Glacier Flexible Retrieval after $10\text{ days}$ .
E
Configure a lifecycle rule to transition objects to S3 Standard-IA after $10\text{ days}$ and expire the objects after $30\text{ days}$ .

Answer

Transitioning the objects from S3 Standard to S3 Standard-IA after 10 days, and transitioning them to S3 Glacier Flexible Retrieval after 40 days while expiring them after 130 days.

Transitioning objects to S3 Standard-IA after 10 days aligns with the end of the high-frequency access period. Since the objects are kept in S3 Standard-IA until day 40 (a duration of exactly 30 days), this complies with the 30-day minimum storage duration requirement for S3 Standard-IA. Transitioning the objects to S3 Glacier Flexible Retrieval after 40 days matches the regulatory storage phase where immediate access is no longer required and a 3 to 5 hour retrieval time is acceptable. Expiring the objects after 130 days ensures they are deleted after the required 90 days in S3 Glacier Flexible Retrieval, satisfying the 90-day minimum storage duration of S3 Glacier Flexible Retrieval without paying early deletion penalties.

Step-by-Step Solution

Analyze the access pattern and durations for each storage tier.

S3 Standard is used for days 0-10 (10 days). S3 Standard-IA is used for days 10-40 (30 days). S3 Glacier Flexible Retrieval is used for days 40-130 (90 days).

Mapping the lifecycle phases ensures we select tiers matching the access frequency and minimum duration requirements.

Validate the S3 Standard-IA transition timing against its billing constraints.

Transitioning to S3 Standard-IA on day 10 and transitioning out on day 40 keeps the objects in S3 Standard-IA for exactly 30 days.

S3 Standard-IA has a minimum storage duration of 30 days; transitioning objects earlier results in early transition billing penalties.

Validate the S3 Glacier Flexible Retrieval transition and expiration timing.

Transitioning to S3 Glacier Flexible Retrieval on day 40 and expiring them on day 130 keeps them in S3 Glacier Flexible Retrieval for 90 days.

S3 Glacier Flexible Retrieval has a minimum storage duration of 90 days; deleting the objects before day 130 would incur early deletion penalties.
