A financial application stores monthly customer account statements (averaging $10\text{ MB}$ each) and daily transactional debug logs (averaging $50\text{ KB}$ each) in an Amazon S3 bucket. The account statements are accessed frequently during the first $30\text{ days}$ but are rarely accessed afterwards, and they must be retained for $7\text{ years}$ for auditing purposes. The debug logs are only needed for troubleshooting within $14\text{ days}$ of creation, after which they can be permanently deleted. Which TWO actions should a solutions architect configure in the S3 Lifecycle rules to meet these requirements in the most cost-effective manner? (Select TWO.)

Configure a lifecycle rule to transition the customer account statements to Amazon S3 Standard-Infrequent Access (S3 Standard-IA) after $30\text{ days}.Cevap
Configure a lifecycle rule to expire the debug logs after $14\text{ days}$ directly from Amazon S3 Standard.Cevap
C
Configure a lifecycle rule to transition the debug logs to Amazon S3 Standard-Infrequent Access (S3 Standard-IA) after $7\text{ days}$ before deleting them.
D
Configure a lifecycle rule to transition the debug logs to Amazon S3 Glacier Flexible Retrieval after $7\text{ days}$ and delete them after $14\text{ days}.
E
Configure a lifecycle rule to transition the customer account statements to Amazon S3 Standard-Infrequent Access (S3 Standard-IA) after $10\text{ days}.

Cevap

Configure a lifecycle rule to transition the customer account statements to Amazon S3 Standard-Infrequent Access (S3 Standard-IA) after

30\text{ days}

and configure a lifecycle rule to expire the debug logs after

14\text{ days}

directly from Amazon S3 Standard.

Transitioning customer account statements to Amazon S3 Standard-Infrequent Access (S3 Standard-IA) after

30\text{ days}

is correct because the statements are large (

10\text{ MB}

) and retained for a long period (

7\text{ years}

), meaning they will not trigger the minimum capacity charge or the minimum storage duration fee. Expiring the debug logs after

14\text{ days}

directly from S3 Standard is correct because at

50\text{ KB}

and with a

14\text{ day}

lifespan, they would incur early deletion penalties and minimum capacity charges if transitioned to S3 Standard-IA or Glacier.

Adım Adım Çözüm

Analyze the size, access patterns, and retention requirement of the customer account statements.

The statements are

10\text{ MB}

(greater than the

128\text{ KB}

minimum size limit), are frequently accessed for only

30\text{ days}

, and must be stored for

7\text{ years}

(longer than the

30\text{ days}

minimum duration limit). S3 Standard-IA is the most cost-effective tier after

30\text{ days}

because it offers lower storage costs without early transition or deletion penalties.

To identify the optimal lifecycle transition timing and tier for the account statements.

Analyze the size, access patterns, and retention requirement of the debug logs.

The debug logs are

50\text{ KB}

(less than the

128\text{ KB}

minimum capacity charge for S3 Standard-IA) and are deleted after

14\text{ days}

(less than the

30\text{ days}

minimum storage duration for S3 Standard-IA and

90\text{ days}

for S3 Glacier).

To evaluate if the debug logs meet the prerequisites for transitioning to colder storage classes without cost penalties.

Select the lifecycle actions that minimize storage, retrieval, and penalty costs.

Transitioning the statements to S3 Standard-IA after

30\text{ days}

and expiring the debug logs directly from S3 Standard after

14\text{ days}

matches the criteria and avoids early deletion or under-capacity billing penalties.

To combine the findings and configure the rules for maximum cost optimization.

Anahtar Kavram

Amazon S3 Lifecycle policies must account for minimum storage durations (

30\text{ days}

for Standard-IA,

90\text{ days}

for Glacier) and minimum capacity charges (

128\text{ KB}

for IA classes) to avoid cost penalties on transient or small objects.
