Test 2 – Question 1

[Panagiotis Antoniou]

“An organization stores and manages financial records of various companies in its on-premises data center, which is almost out of space. The management decided to move all of their existing records to a cloud storage service. All future financial records will also be stored in the cloud. For additional security, all records must be prevented from being deleted or overwritten.

Which of the following should you do to meet the above requirement?

Hence, the correct answer in this scenario is: Use AWS DataSync to move the data. Store all of your data in Amazon S3 and enable object lock.

The option that says: Use AWS DataSync to move the data. Store all of your data in Amazon EFS and enable object lock is incorrect because Amazon EFS only supports file locking. Object lock is a feature of Amazon S3 and not Amazon EFS.

The options that says: Use AWS Storage Gateway to establish hybrid cloud storage. Store all of your data in Amazon S3 and enable object lock is incorrect because the scenario requires that all of the existing records must be migrated to AWS. The future records will also be stored in AWS and not in the on-premises network. This means that setting up a hybrid cloud storage is not necessary since the on-premises storage will no longer be used.

The option that says: Use AWS Storage Gateway to establish hybrid cloud storage. Store all of your data in Amazon EBS, and enable object lock is incorrect because Amazon EBS does not support object lock. Amazon S3 is the only service capable of locking objects to prevent an object from being deleted or overwritten.”

How can the answer state that “Use AWS Storage Gateway to establish hybrid cloud storage. Store all of your data in Amazon S3 and enable object lock” is incorrect when in the details explanation it also states:

“AWS DataSync is primarily used to migrate existing data to Amazon S3. On the other hand, AWS Storage Gateway is more suitable if you still want to retain access to the migrated data and for ongoing updates from your on-premises file-based applications.”

Don’t we indeed want to indeed retain access to the migrated data? Isn’t it more complex to use DataSync to schedule subsequent incremental transfers?

Hello Panagiotis,

Thanks for sharing your thoughts on this one.

It was indicated that existing and future financial records would be stored in the cloud (AWS) but made no mention of how they are going to be accessed. Storage Gateway isn’t necessary for file retrieval. You can still access S3 without it. For example, the company could create an internal application that fetches records from S3. The main concern of the scenario revolves around data migration, not establishing hybrid networks.

Let me know if this this helps.

Hi Carlo,

It helps indeed, thank you for clarifying. That said, can’t help but think that the question could have made a better job of explaining what we are looking for and afterwards explaining why its option is valid or not valid
