A. B. C. D. E. F. G.Answer: A,C,E,F.
Option A is correct - Defines a data node using DynamoDB, which is specified as an input to EMRActivity which launches EMR Cluster
https://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-Option B is incorrect -Defines a data node using DynamoDB, which is specified as an input to EMRActivity which launches EMR Cluster
https://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-Option C is correct -Defines a data node using Amazon S3 aka S3DataNode.
It is already server side encrypted
https://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-Option D is incorrect - Defines a data node using Amazon S3 aka S3DataNode.
It is already server side encrypted
https://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-Option E is correct - A precondition to check whether Amazon S3 objects with the given prefix is present
https://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-Option F is correct - Use EmrActivity to process the restoration
https://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-Option G is incorrect - Use EmrActivity to process the restoration
https://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-To restore a backup of a DynamoDB table available in S3 to a development environment, the following steps can be taken:
Define a data node using Amazon S3: The first step is to define a data node using Amazon S3, which will specify the location of the backup data in S3. This can be done using the S3DataNode.
Enable server-side encryption on S3DataNode: It is recommended to enable server-side encryption on S3DataNode to secure the backup data while transferring it to the development environment. By default, s3EncryptionType set to NONE, but it can be changed to SSE-KMS or SSE-S3 for added security.
Check preconditions: Before starting the restoration process, it is important to check whether Amazon S3 objects with the given prefix (backup data) are present. This can be done using a precondition.
Launch EMR Cluster: The next step is to launch an EMR Cluster using the EMRActivity. The EMR cluster can be used to process the restoration of the backup data.
Launch EC2 Server: Alternatively, an EC2 server can be launched using EC2Activity to process the restoration of the backup data.
Process the restoration: The restoration of the backup data can be processed using the EMRActivity or EC2Activity depending on the chosen approach.
Therefore, the correct steps for restoring a backup of a DynamoDB table available in S3 to a development environment are:
Option A and B are incorrect as they mention launching EMR or EC2 servers as the first step, without mentioning the use of S3DataNode or checking preconditions.
