Correct Answer - C.

Standard or Bulk retrieval options can be used with the S3 Glacier Deep Archive storage class.

An expedited retrieval option can be used with the S3 Glacier storage class to restore data.

Also, restoration can be changed for the S3 Glacier storage class while restoration is in progress.

The typical Time frame for data retrieval is as follows.

Retrieval option.

S3 Glacier storage class.

Expedited.

1-5 mins.

Not Supported.

Standard.

3-5 hours.

12 hours.

Bulk.

5-12 hours.

48 hours.

Option A is incorrect as Standard retrieval option will work for the S3 Glacier Deep Archive storage class, but it will take 3-5 hours to retrieve objects from the S3 Glacier storage class while with the Expedited retrieval option.

Same data can be available in less than 5 minutes.

Option B is incorrect as the Standard retrieval option will take 3-5 hours to retrieve an object from the S3 Glacier storage class while with the Expedited retrieval option.

Same data can be available in less than 5 minutes.

Option D is incorrect as the Expedited retrieval option is Not supported for the S3 Glacier Deep Archive storage class.

The correct answer is B: Use Standard retrieval options for objects to be restored from the S3 Glacier storage class & expedited retrieval options for data stored in the S3 Glacier Deep Archive storage class.

Explanation:

Amazon S3 Glacier and Amazon S3 Glacier Deep Archive are low-cost storage classes for data archiving that provide secure and durable object storage for long-term retention of data. S3 Glacier is optimized for infrequently accessed data, while S3 Glacier Deep Archive is optimized for very rarely accessed data.

When you archive data to these storage classes, the data is not immediately available for retrieval. Instead, you have to initiate a retrieval job that can take hours or even days to complete, depending on the retrieval option you choose.

For urgent data retrieval needs, Amazon S3 Glacier offers expedited retrieval options for retrieving data from S3 Glacier storage class. Expedited retrieval provides sub-5 minute access to your data when you need it most. However, expedited retrieval is not available for S3 Glacier Deep Archive storage class.

Therefore, in this case, it is recommended to use standard retrieval options for objects stored in S3 Glacier storage class and expedited retrieval options for data stored in the S3 Glacier Deep Archive storage class. This approach will help to ensure that the data is available as quickly as possible while keeping the cost of retrieval low for rarely accessed data.

Option A, using standard retrieval options for both S3 Glacier and S3 Glacier Deep Archive storage classes, may result in slower data retrieval times for data in the S3 Glacier Deep Archive storage class.

Option C, using expedited retrieval options for data stored in the S3 Glacier storage class and standard retrieval options for data stored in the S3 Glacier Deep Archive storage class, is not recommended because it would be more expensive and would not optimize the retrieval times for both storage classes.

Option D, using expedited retrieval options for both S3 Glacier and S3 Glacier Deep Archive storage classes, is also not recommended because expedited retrieval is not available for S3 Glacier Deep Archive storage class.
