Question 1

A media site reads the same S3 assets many times every day and requires millisecond access. Which storage class best matches the access pattern without retrieval charges?

1. Use S3 Standard-IA.
2. Use S3 One Zone-IA.
3. Use S3 Glacier Deep Archive.
4. Use S3 Standard.
5. Use S3 Intelligent-Tiering.

Correct Answer: D

 

Correct Answer

Answer D is correct because S3 Standard is intended for frequently accessed data with millisecond access and no minimum storage duration. This directly meets the decisive requirement: S3 Standard.

Incorrect Answers

Answer A is incorrect because Standard-IA is multi-AZ, millisecond-access storage for long-lived data accessed infrequently and includes retrieval charges and a minimum duration. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: S3 Standard.

Answer B is incorrect because One Zone-IA stores infrequently accessed data in one AZ and is appropriate only when that AZ-level resilience tradeoff is acceptable. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: S3 Standard.

Answer C is incorrect because Deep Archive is designed for very long-lived archive data with the lowest storage price among the listed choices and retrieval measured in hours. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: S3 Standard.

Answer E is incorrect because Intelligent-Tiering moves eligible objects among access tiers as patterns change, reducing the need to predict access frequency. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: S3 Standard.

Question 6

A bucket receives millions of 20-KB temporary objects that live for 10 days. A proposed lifecycle rule moves them to Standard-IA after one day. What is the best cost action?

3. Account for Deep Archive minimum storage duration before choosing the transition.
4. Configure Lifecycle to abort incomplete multipart uploads after a bounded period.
5. Add a lifecycle rule for noncurrent version expiration after the approved retention period.

Correct Answer: A

 

Correct Answer

Answer A is correct because Minimum billable object sizes, transition requests, and minimum-duration charges can make early transitions uneconomic for tiny short-lived objects. This directly meets the decisive requirement: keep short-lived tiny objects out of IA transition.

Question 11

An EC2 fleet uses gp2 volumes sized at 2 TB only to obtain IOPS; actual stored data is 200 GB. Which optimization should be evaluated?

A recurring 2-TB nightly copy has ample private network bandwidth and only changed files should move. Which design is generally preferable to shipping physical media repeatedly?

1. Use a managed online incremental transfer such as DataSync.
2. Verify current AWS offline-transfer availability and customer eligibility rather than assuming Snowball Edge can be ordered.
3. Use AWS Transfer Family.
4. Use Amazon S3 File Gateway.
5. Use AWS DataSync.

Correct Answer: A

 

Correct Answer

Answer A is correct because When bandwidth is sufficient and transfers repeat, incremental network synchronization avoids repeated logistics and transfers only changed data. This directly meets the decisive requirement: managed incremental online transfer.

Incorrect Answers

Answer B is incorrect because Snowball Edge availability has changed and new-customer designs must use currently supported transfer options instead of relying on a retired ordering path. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: managed incremental online transfer.

Answer C is incorrect because Transfer Family provides managed file-transfer protocol endpoints, including SFTP, with AWS storage backends. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: managed incremental online transfer.

Answer D is incorrect because File Gateway exposes local file protocols while storing objects in S3 and caching frequently used data on premises. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: managed incremental online transfer.

Answer E is incorrect because DataSync is designed for accelerated online data movement between supported on-premises storage and AWS storage and can run recurring incremental transfers. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: managed incremental online transfer.

 

Question 21

Finance wants to see monthly S3 spend by application team using tags that the organization controls. Which setup best supports the allocation?

1. Enable S3 Requester Pays where the sharing model supports it.

Question 26

Daily backups must be retained for 30 days and restore within minutes. Which policy is more cost-aware than sending every backup immediately to Deep Archive?

1. Remove backup copies that do not satisfy a distinct recovery, isolation, or compliance requirement.
2. Use a storage tier whose minimum duration and retrieval behavior match the 30-day retention and minutes-level restore requirement.
3. Keep restore validation, key access, and recovery procedures in the design even when archive storage is cheap.
4. Use a deep archival S3 storage class when its retrieval time and minimum duration fit the seven-year requirement.
5. Apply tiered retention so frequent snapshots expire on schedule while required long-term monthly copies remain.

Correct Answer: B

 

Correct Answer

Answer B is correct because A low storage price alone can be offset by minimum-duration and retrieval constraints when retention is short and restore is urgent. This directly meets the decisive requirement: use storage tier matching short retention and restore SLA.

Incorrect Answers

Answer A is incorrect because Additional identical copies add storage cost but provide no justified value when the required failure scenarios are already covered. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: use storage tier matching short retention and restore SLA.

Answer C is incorrect because A lower-cost archive is not useful if the organization cannot actually decrypt and restore it within the required recovery process. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: use storage tier matching short retention and restore SLA.

Answer D is incorrect because Long retention and rare, delay-tolerant restores are the intended economics for deep archival tiers. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: use storage tier matching short retention and restore SLA.

Answer E is incorrect because Retention granularity prevents paying indefinitely for recovery points that policy no longer requires. It can be useful in a different cost or architecture situation, but it does not meet the decisive requirement here: use storage tier matching short retention and restore SLA.
