    Hi, Below are the 2 questions with seemingly conflicting answers. kindly clarify

    options highlighted in bold are correct ones FYR. One says install the datasync agents on premises and other says as ec2 instances where as explanation says “The DataSync agent should be deployed on-premises instead since it is where the data is stored.”

    A) A telecommunications provider is initiating a large-scale migration of 5 petabytes of Hadoop Distributed File System (HDFS) data to Amazon S3. The network bandwidth isn’t a concern as they have a dedicated 10Gb/s Direct Connection to AWS. They plan to prioritize moving historical data in the first phase, followed by a daily incremental data transfer of 150TB. Moreover, it’s crucial that the system supporting this migration is highly available and resilient to hardware failures.

    Which solution will satisfy these requirements?

    Deploy AWS DataSync agents as EC2 instances across availability zones. Create an HDFS transfer location using the on-premises HDFS cluster as the source.

    B) A company is currently storing customer records on a local data center. Most of the records are infrequently accessed by data engineers performing analysis and data visualizations. The company plans to migrate its data to AWS Cloud for long-term storage and to leverage the analytics capabilities of Amazon EMR, Amazon Athena, and Amazon QuickSight. The company wants a solution that automates and accelerates the copying of large amounts of data to an AWS storage service. Furthermore, the solution should provide automatic data integrity checks and encryption of data-in-transit and at-rest.
