Domain 4.1: Storage Cost Optimization

A company stores millions of images in an Amazon S3 bucket. The access patterns for the images are highly unpredictable; some images are accessed daily, while others are not accessed for months. The company wants to minimize storage costs without incurring retrieval fees or operational overhead. Which S3 storage class should be used?

A hospital needs to retain patient records for 10 years to meet regulatory compliance. The records are rarely accessed after the first year, but if needed, a retrieval time of 12 hours is acceptable. Which Amazon S3 storage class is the MOST cost-effective for long-term retention?

A company takes daily snapshots of its Amazon EBS volumes. The company has noticed that its AWS bill for EBS snapshots is increasing rapidly. The company only needs to retain snapshots for 30 days. Which TWO actions should a solutions architect take to optimize these costs? (Select TWO.)

The company wants to optimize storage costs without incurring retrieval fees or operational overhead. Which S3 storage class should they use?

A company stores log files in Amazon S3. The logs are frequently accessed for the first 30 days. After 30 days, they are rarely accessed but must be kept immediately available for 90 days. After 90 days, they must be retained for compliance for 5 years and are rarely accessed. Which TWO lifecycle rules provide the MOST cost-effective solution? (Select TWO.)

A company takes daily snapshots of their Amazon EBS volumes. They have noticed that their snapshot storage costs are growing rapidly because old snapshots are never deleted. What is the MOST operationally efficient way to manage this?

A company takes daily EBS snapshots of their EC2 instances. Over time, the storage costs for these snapshots have grown significantly. They want to automate the deletion of snapshots older than 30 days. Which TWO approaches can achieve this? (Select TWO.)

A company wants to use Amazon Macie to discover sensitive data in their S3 buckets. However, they have petabytes of data and are concerned about the cost of scanning everything. Which TWO strategies should a solutions architect recommend to optimize Macie costs? (Select TWO.)

A company stores millions of images in an Amazon S3 bucket. The images are accessed frequently for the first 30 days, then rarely accessed, but must be kept indefinitely for compliance. The company wants to minimize storage costs without impacting the performance of retrieving new images. <br/><br/>Which S3 lifecycle policy should be implemented?

A company uses Amazon S3 to store log files. The logs are analyzed daily for the first 7 days, then rarely accessed. However, compliance requires the logs to be kept for 5 years. The company wants to minimize storage costs. <br/><br/>Which lifecycle policy is MOST cost-effective?

A company stores millions of images in Amazon S3. The access patterns are unpredictable; some images are accessed daily, while others are not accessed for months. The company wants to optimize storage costs without incurring retrieval fees or operational overhead. Which S3 storage class should they use?

A company generates daily log files that are stored in Amazon S3. The logs are frequently accessed for the first 30 days. From day 31 to 90, they are rarely accessed but must be available within milliseconds. After 90 days, they are retained for compliance for 7 years and rarely accessed. Which TWO lifecycle rules should be implemented to minimize costs? (Select TWO.)

A company takes daily EBS snapshots of their EC2 instances. Over time, the storage costs for these snapshots have grown significantly. The company needs to retain snapshots for 30 days for operational recovery, and for 1 year for compliance. Which TWO actions should be taken to optimize costs? (Select TWO.)

A company uses Amazon Macie to scan S3 buckets for sensitive data. They have a bucket containing 50 TB of historical logs that rarely change, and a bucket with 1 TB of active user uploads. To optimize Macie costs, how should the solutions architect configure the scanning?

A company stores millions of images in Amazon S3. The access patterns for these images are highly unpredictable; some images are accessed daily, while others are not accessed for months. The company wants to automatically optimize storage costs without incurring retrieval fees or operational overhead.<br/><br/>Which S3 storage class should be used?

A hospital generates large amounts of patient data daily. The data is frequently accessed for the first 30 days. After 30 days, it is rarely accessed but must be retained immediately accessible for 1 year. After 1 year, it must be archived for 7 years for compliance.<br/><br/>Which TWO actions should a solutions architect take to minimize costs? (Select TWO.)

A company takes daily snapshots of its Amazon EBS volumes. The company has noticed that its EBS snapshot costs are growing rapidly. They need to retain daily snapshots for 30 days, and monthly snapshots for 1 year.<br/><br/>Which TWO actions should a solutions architect take to automate and optimize this process? (Select TWO.)

A company stores millions of images in Amazon S3. They do not know the access patterns of the images; some are accessed daily, while others are not accessed for months. They want to minimize storage costs without incurring retrieval fees or operational overhead. Which S3 storage class should they use?

A company has a large number of EBS snapshots that are kept for compliance purposes. They want to reduce the cost of storing these snapshots, as they are rarely accessed and only needed for disaster recovery. What is the MOST cost-effective solution?

A company has a fleet of EC2 instances that generate log files. The logs are sent to Amazon CloudWatch Logs. The company needs to retain these logs for 5 years for compliance, but they are rarely queried after 30 days. What is the MOST cost-effective way to store these logs long-term?
