Q

A media company wants to find and subscribe to third-party data sources to enrich their existing datasets with new insights.

Which AWS service would be the best fit for this requirement?

  1. AWS Glue
  2. AWS Data Pipeline
  3. AWS Data Exchange
  4. AWS Redshift
A

3. AWS Data Exchange

AWS Data Exchange is the correct answer because this service allows customers to find, subscribe to, and use third-party data in the cloud. Companies can subscribe to a diverse selection of data products provided by various data providers. The media company in this scenario can enrich their existing datasets through AWS Data Exchange by easily finding and subscribing to third-party data sources.

  • AWS Glue is incorrect. Glue is a fully managed extract, transform, and load (ETL) service that makes it easy to prepare and load data for analytics. While AWS Glue can work with data, it does not primarily facilitate the subscription to third-party data sources as described in the scenario.
  • AWS Data Pipeline is incorrect. This service is designed to facilitate the processing and transfer of data between different AWS services and on-premises data sources. It isn’t primarily used for subscribing to third-party data sources.
  • AWS Redshift is incorrect. Redshift is a data warehouse service that is used to analyze data using standard SQL and existing Business Intelligence tools. It doesn’t allow you to find and subscribe to third-party data products.

Q

Which AWS services facilitate building secure and scalable mobile and web applications, offering features such as real-time updates and offline functionalities?

(Select TWO.)

  1. AWS Lambda
  2. AWS AppSync
  3. AWS Amplify
  4. AWS CodeDeploy
  5. Amazon API Gateway
A

2. AWS AppSync
3. AWS Amplify

AWS AppSync and AWS Amplify are the correct answers as both services facilitate the building of secure and scalable mobile and web applications.

AWS AppSync enables the creation of flexible APIs, including options for real-time updates and offline functionalities. AWS Amplify is a set of tools and services that can be used to build scalable full-stack apps powered by AWS, also supporting real-time functionalities and offline operations.

  • AWS Amplify is also a correct answer (as explained above.)
  • AWS Lambda is incorrect because, while it is a service that lets you run your code without provisioning or managing servers, it is more about executing backend functions rather than facilitating the development of secure and scalable applications with real-time and offline functionalities.
  • AWS CodeDeploy is incorrect because it is a deployment service that automates application deployments to specified compute environments, including Amazon EC2 instances and AWS Lambda functions, but does not inherently facilitate the building of mobile and web applications with the described features.
  • Amazon API Gateway is incorrect because, although it allows for the creation, publishing, maintenance, monitoring, and securing of REST, HTTP, and WebSocket APIs at any scale, it doesn’t specifically facilitate building applications with real-time updates and offline functionalities as a standalone service.

Q

An organization is seeking a fully managed service to create and publish interactive dashboards that can be accessed from any device.

Which AWS service would be the most appropriate choice for this requirement?

  1. Amazon Redshift
  2. Amazon QuickSight
  3. AWS Glue
  4. Amazon EMR
A

2. Amazon QuickSight

Amazon QuickSight is the correct answer because it is a fully managed business intelligence service from AWS that makes it easy to create and publish interactive dashboards that include ML Insights. Dashboards can be accessed from any device, and embedded into your applications, portals, and websites.

  • Amazon Redshift is incorrect as it is primarily a data warehousing service that allows users to analyze data using standard SQL and existing Business Intelligence tools. While it integrates with various visualization tools, including QuickSight, it is not a tool for creating and publishing dashboards itself.
  • AWS Glue is incorrect because it is a fully managed extract, transform, and load (ETL) service that makes it easy for users to prepare and load their data for analytics. It is not designed to create and publish interactive dashboards.
  • Amazon EMR is incorrect because, although it can process vast amounts of data across resizable clusters of Amazon EC2 instances, it is not a business intelligence tool designed to create and publish interactive dashboards.

Q

Which AWS service can be used to prepare and load data for analytics using an extract, transform and load (ETL) process?

  1. AWS Lambda
  2. AWS Glue
  3. Amazon EMR
  4. Amazon Athena
A

2. AWS Glue

AWS Glue is a fully managed extract, transform, and load (ETL) service that makes it easy for customers to prepare and load their data for analytics.
You can point AWS Glue to data stored on AWS, and AWS Glue discovers the data and stores the associated metadata (e.g. table definition and schema) in the AWS Glue Data Catalog. Once cataloged, the data is immediately searchable, queryable, and available for ETL.

  • AWS Lambda is incorrect. AWS Lambda is a serverless application that runs code as functions in response to events
  • Amazon EMR is incorrect. Amazon Elastic Map Reduce (EMR) provides a managed Hadoop framework that makes it easy, fast, and cost-effective to process vast amounts of data across dynamically scalable Amazon EC2 instances
  • Amazon Athena is incorrect. Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL.
