Question 1

A photography studio stores its high-resolution image files in an Amazon S3 bucket. Recently, they encountered issues with accidental overwrites of important files. The studio requires a solution to prevent the overwriting and accidental deletion of their images while ensuring that the latest version of a file is readily accessible.

Which single feature should the photography studio enable on their S3 bucket to address this issue effectively?

A : Activate S3 Versioning to maintain multiple versions of each file.

B : Enable S3 Object Lock in compliance mode for strict WORM (Write Once, Read Many) protection.

C : Configure S3 Intelligent-Tiering to manage the storage of the files efficiently.

D : Implement S3 Lifecycle policies to archive older versions of files to S3 Glacier.

Answer: A

Question 2

A retail organization utilizes Amazon Redshift as its primary data warehousing solution. To ensure that their reporting dashboards reflect the most current data, they need a low-maintenance method to regularly update their Redshift materialized views.

Which approach requires the least effort to automate the updating process for the materialized views?

A : Implement an AWS Lambda function to execute the refresh command on a set schedule.

B : Create an Amazon EventBridge rule to invoke a refresh command in Amazon Redshift.

C : Configure Amazon Redshift to automatically refresh materialized views at regular intervals.

D : Schedule an Amazon Redshift event subscription to trigger materialized view refreshes.

Answer: A

Question 3

A Data Engineering Team is setting up a new job in AWS Glue ETL. They have configured their data sources and targets, defined the necessary transformations, but when they attempt to run the job, it fails with an authorization error. The team needs to ensure that the AWS Glue job has the necessary permissions to access the required AWS resources for execution.

What should the team do to resolve this issue and successfully run the Glue ETL job?

A : Enable AWS Glue Data Catalog encryption, which automatically grants necessary permissions to the ETL job.

B : Attach an IAM policy directly to the AWS Glue ETL job with the necessary permissions.

C : Create an IAM group with the appropriate permissions and add the AWS Glue service account to this group.

D : Assign an AWS Glue Service Role to the ETL job, ensuring it has the required permissions to access necessary resources.

Answer: D

Question 4

A Data Engineering team is planning to migrate a complex legacy Microsoft SQL Server database to Amazon Aurora MySQL. The existing SQL Server database contains several stored procedures, triggers, and complex joins. The team is concerned about potential compatibility issues and the effort needed to rewrite substantial amounts of SQL code manually. They aim to use AWS services to facilitate an efficient and accurate schema conversion, ensuring minimal downtime and data consistency during the migration process.

What sequence of steps should the team follow using AWS services to achieve this migration?

A : Use AWS Database Migration Service (AWS DMS) for an initial assessment of the schema conversion, apply the AWS Schema Conversion Tool (AWS SCT) for the actual schema conversion, then use AWS DMS again to migrate the data to Amazon Aurora MySQL.

B : First, apply the AWS Schema Conversion Tool (AWS SCT) to assess and convert the SQL Server schema and SQL code to a format compatible with Aurora MySQL. Following this, use AWS DMS to migrate the data from SQL Server to Aurora MySQL.

C : Directly utilize AWS DMS to migrate the SQL Server database to Amazon Aurora MySQL, relying on the DMS’s built-in schema conversion feature to handle any compatibility issues during the migration.

D : Start with the AWS Schema Conversion Tool (AWS SCT) for converting the SQL Server schema and code to Aurora MySQL, utilize Amazon RDS to temporarily host the converted schema, and then use AWS DMS for the final migration to Aurora MySQL.

Answer: B

Question 5

A financial services company is storing time-series data in a relational database hosted on Amazon RDS. The company wants to improve query performance for reports that are run on a monthly basis, which involve large scans over historical data. The solution should optimize costs and maintain current data integrity constraints.

Which approach should the company take?

A : Migrate the database to Amazon Redshift and utilize Redshift's materialized views to optimize the query performance for repetitive and predictable analysis patterns.

B : Use Amazon RDS for MySQL and implement read replicas to distribute the read load during the execution of large scan operations.

C : Convert the database to use Amazon Aurora with MySQL compatibility and implement Aurora's parallel query feature for faster data scans.

D : Migrate the database to Amazon DynamoDB and use DynamoDB Accelerator (DAX) to cache frequent read requests and improve response times.
