Topic 1 Question 58
A company has a monolithic application that is critical to the company’s business. The company hosts the application on an Amazon EC2 instance that runs Amazon Linux 2. The company’s application team receives a directive from the legal department to back up the data from the instance’s encrypted Amazon Elastic Block Store (Amazon EBS) volume to an Amazon S3 bucket. The application team does not have the administrative SSH key pair for the instance. The application must continue to serve the users.
Which solution will meet these requirements?
Attach a role to the instance with permission to write to Amazon S3. Use the AWS Systems Manager Session Manager option to gain access to the instance and run commands to copy data into Amazon S3.
Create an image of the instance with the reboot option turned on. Launch a new EC2 instance from the image. Attach a role to the new instance with permission to write to Amazon S3. Run a command to copy data into Amazon S3.
Take a snapshot of the EBS volume by using Amazon Data Lifecycle Manager (Amazon DLM). Copy the data to Amazon S3.

The correct answer is C. Taking a snapshot of the EBS volume using Amazon Data Lifecycle Manager (DLM) will meet the requirements because it allows you to create a backup of the volume without the need to access the instance or its SSH key pair. Additionally, DLM allows you to schedule the backups to occur at specific intervals and also enables you to copy the snapshots to an S3 bucket. This approach will not impact the running application as the backup is performed on the EBS volume level.
Option A is not correct because the instance would need an IAM role with permission to write to S3 and access to the instance via Systems Manager Session Manager.
Option B is not correct because it would require stopping the instance, which would impact the running application.
Option D is not correct because it would require stopping the instance and creating a new EC2 instance, which would impact the running application.

taking a backup of the data to s3. aws doesn't allow up to view snapshots in s3

I am leaning towards A due to statements of "Business critical and The application must continue to serve the users." WHen You do snapshots performance might be affected and essentially not all of the EBS volume needs to be copied just specific data
