Answer: Configure access to Amazon S3 for each user. Create an S3 Lifecycle policy to transition the data to S3 Glacier Flexible Retrieval after 7 days.
## Explanation **Correct Answer: D** **Why Option D is correct:** 1. **S3 Glacier Flexible Retrieval** has a retrieval time of up to 12 hours for standard retrievals (or 1-5 minutes for expedited retrievals), which meets the requirement of "maximum retrieval time of 24 hours" after 7 days. 2. **S3 Glacier Deep Archive** (Option B) has retrieval times of up to 48 hours for standard retrievals, which exceeds the 24-hour requirement. 3. **Amazon FSx File Gateway** (Option C) doesn't provide the required retrieval time guarantee for archived data. 4. **AWS DataSync** (Option A) is just a data transfer service and doesn't address the storage and retrieval requirements. **Key Requirements Analysis:** - **Frequent access for up to 7 days**: Files need to be readily accessible during this period - **After 7 days**: Maximum retrieval time of 24 hours - **SMB file server in data center**: Needs integration with AWS **Solution Architecture:** 1. Configure access to Amazon S3 for users 2. Use S3 Lifecycle policy to transition data to S3 Glacier Flexible Retrieval after 7 days 3. S3 Glacier Flexible Retrieval provides: - Standard retrieval: 3-5 hours (well within 24-hour requirement) - Bulk retrieval: 5-12 hours (also within requirement) - Expedited retrieval: 1-5 minutes (for urgent needs) **Why other options are incorrect:** - **Option A**: DataSync only copies data but doesn't provide the storage tiering or retrieval capabilities needed. - **Option B**: S3 Glacier Deep Archive has retrieval times of up to 48 hours, which violates the 24-hour maximum requirement. - **Option C**: FSx File Gateway doesn't specify the appropriate storage class and doesn't guarantee the retrieval time requirement. This solution provides cost-effective storage while meeting the retrieval time requirements for archived data.

A company runs an SMB file server in its data center. The file server stores large files that the company frequently accesses for up to 7 days after the file creation date. After 7 days, the company needs to be able to access the files with a maximum retrieval time of 24 hours.
Which solution will meet these requirements?
A
Use AWS DataSync to copy data that is older than 7 days from the SMB file server to AWS.
B
Create an Amazon S3 File Gateway to increase the company's storage space. Create an S3 Lifecycle policy to transition the data to S3 Glacier Deep Archive after 7 days.
C
Create an Amazon FSx File Gateway to increase the company's storage space. Create an Amazon S3 Lifecycle policy to transition the data after 7 days.
D
Configure access to Amazon S3 for each user. Create an S3 Lifecycle policy to transition the data to S3 Glacier Flexible Retrieval after 7 days.
