Timed Mode Set 2 – AWS Certified Solutions Architect Associate – Question 4

[tugjg]

An organization is currently using a tape backup solution to store its application data on-premises. They plan to use a cloud storage service to preserve the backup data for up to 10 years that may be accessed about once or twice a year.

Which of the following is the most cost-effective option to implement this solution?

A: Use AWS Storage Gateway to backup the data directly to Amazon S3 Glacier.

B: Order an AWS Snowball Edge appliance to import the backup directly to Amazon S3 Glacier.

C: Use AWS Storage Gateway to backup the data and transition it to Amazon S3 Glacier Deep Archive.

<b style=””>D: Use Amazon S3 to store the backup data and add a lifecycle rule to transition the current version to Amazon S3 Glacier.

According to the test, answer C is correct.

Problems:

• Answer A is considered wrong because “Although this is a valid solution, moving to S3 Glacier is more expensive than directly backing it up to Glacier Deep Archive.” However, Answer A does not specify which class of S3 Glacier is being used. Perhaps it’s S3 Glacier Flexible Retrieval, which is cheaper than Glacier Deep Archive?
• The supposed correct answer, D, mentions using a lifecycle rule to transition the data to Amazon S3 Glacier. However, the question deals with tape storage, and I think Tape Gateway let you to upload directly to S3 Glacier – no need to go to S3 Standard and using a lifecycle policy to transition.

• Archiving tapes – When your backup software ejects a tape, your gateway moves the tape to the archive for long-term storage. The archive is located in the AWS Region in which you activated the gateway. Tapes in the archive are stored in the virtual tape shelf (VTS). The VTS is backed by S3 Glacier Flexible Retrieval or S3 Glacier Deep Archive, low-cost storage service for data archiving, backup, and long-term data retention.

Hello tugjg,

Thank you for bringing this to our attention.

You’re correct that some of the options did not clearly specify the S3 Glacier storage class. What was previously referred to simply as S3 Glacier is now called S3 Glacier Flexible Retrieval.

We’ll make the necessary updates to reflect the current naming. Even with that clarification, S3 Glacier Deep Archive is still the more cost-effective choice for data accessed infrequently and retained for up to 10 years.

Let us know if you need further assistance.

Withdrawn. I reread the product specifications.
