Files from multiple data sources arrive in an Amazon S3 bucket on a regular basis. A data engineer wants to ingest new files into Amazon Redshift in near real time when the new files arrive in the S3 bucket. Which solution will meet these requirements?

A : Use the query editor v2 to schedule a COPY command to load new files into Amazon Redshift.

B : Use the zero-ETL integration between Amazon Aurora and Amazon Redshift to load new files into Amazon Redshift.

C : Use AWS Glue job bookmarks to extract, transform, and load (ETL) load new files into Amazon Redshift.

D : Use S3 Event Notifications to invoke an AWS Lambda function that loads new files into Amazon Redshift.

Answer: D

Question 2

A data engineer has two datasets that contain sales information for multiple cities and states. One dataset is named reference, and the other dataset is named primary. The data engineer needs a solution to determine whether a specific set of values in the city and state columns of the primary dataset exactly match the same specific values in the reference dataset. The data engineer wants to use Data Quality Definition Language (DQDL) rules in an AWS Glue Data Quality job. Which rule will meet these requirements?

A : DatasetMatch "reference" "city->ref_city, state->ref_state" = 1.0

B : ReferentialIntegrity "city,state" "reference.{ref_city,ref_state}" = 1.0

C : DatasetMatch "reference" "city->ref_city, state->ref_state" = 100

D : ReferentialIntegrity "city,state" "reference.{ref_city,ref_state}" = 100

Answer: A

A data engineer at a healthcare company needs to implement a solution to ensure that sensitive patient data in an Amazon S3 bucket is encrypted at rest. The company's security policy mandates the use of customer-managed keys for encryption to meet compliance requirements. The data engineer must also ensure that key usage can be audited.

Which of the following would be the MOST suitable solution?

A : Use server-side encryption with AWS KMS managed keys (SSE-KMS), create a customer managed key, and enable logging and auditing via AWS CloudTrail.

B : Encrypt data client-side using a customer-managed encryption library before uploading to S3, and utilize AWS CloudWatch for monitoring access.

C : Implement server-side encryption with AWS KMS managed keys (SSE-KMS), using an AWS managed key (default key), and track key usage through AWS Config.

D : Enable server-side encryption on the S3 bucket with Amazon S3 managed keys (SSE-S3) and use AWS CloudTrail to audit key usage.

Answer: A

Question 4

A data engineer wants to orchestrate a set of extract, transform, and load (ETL) jobs that run on AWS.
