  A company needs to use a serverless interactive query service to analyze data in Amazon S3. The query service must support standard SQL.

  Which AWS service will meet these requirements?

  A. Amazon Redshift
  B. AWS Glue
  C. Amazon Athena
  D. Amazon Kinesis Data Streams
  C. Amazon Athena

  ---

  Explanation

  Amazon Athena is a serverless interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. Athena is ideal for quick, ad-hoc querying but it can also handle complex analysis, including large joins, window functions, and arrays. Athena scales automatically--executing queries in parallel--so results are fast, even with large datasets and complex queries. Amazon Redshift is a fully managed, petabyte-scale data warehouse service that can run complex analytic queries against structured and semi-structured data using standard SQL. However, it is not a serverless service and requires provisioning and managing clusters of nodes. AWS Glue is a fully managed extract, transform, and load (ETL) service that makes it easy to prepare and load your data for analytics. However, it is not a query service and does not support standard SQL. Amazon Kinesis Data Streams is a service that enables you to build custom applications that process or analyze streaming data for specialized needs. However, it is not a query service and does not support standard SQL.

• Question 586:

  Which AWS service or tool provides users with the ability to monitor AWS service quotas?

  A. AWS CloudTrail
  B. AWS Cost and Usage Reports
  C. AWS Trusted Advisor
  D. AWS Budgets
  C. AWS Trusted Advisor

  ---

  Explanation

  The correct answer is C because AWS Trusted Advisor is an AWS service or tool that provides users with the ability to monitor AWS service quotas. AWS Trusted Advisor is an online tool that provides users with real-time guidance to help them provision their resources following AWS best practices. One of the categories of checks that AWS Trusted Advisor performs is service limits, which monitors the usage of each AWS service and alerts users when they are close to reaching the default limit. The other options are incorrect because they are not AWS services or tools that provide users with the ability to monitor AWS service quotas. AWS CloudTrail is a service that enables users to track user activity and API usage across their AWS account. AWS Cost and Usage Reports is a tool that enables users to access comprehensive information about their AWS costs and usage. AWS Budgets is a tool that enables users to plan their service usage, costs, and reservations.

• Question 588:

  A company stores data in an Amazon S3 bucket.

  Which task is the responsibility of AWS?

  A. Configure an S3 Lifecycle policy.
  B. Activate S3 Versioning.
  C. Configure S3 bucket policies.
  D. Protect the infrastructure that supports S3 storage.
  D. Protect the infrastructure that supports S3 storage.

  According to the AWS Shared Responsibility Model, AWS is responsible for protecting the infrastructure that runs all of the services offered in the AWS Cloud, including Amazon S3. This infrastructure includes hardware, software, networking,

  and facilities that support AWS services.

  Why Other Options Are Not Suitable:

  Configure an S3 Lifecycle Policy: Incorrect. Configuring S3 Lifecycle policies to manage object lifecycles (e.g., transitioning objects to different storage classes or deleting them after a certain period) is the customer's responsibility.

  Activate S3 Versioning: Incorrect. Enabling S3 Versioning is a customer responsibility for managing data protection.

  Configure S3 Bucket Policies: Incorrect. Setting and managing S3 bucket policies to control access is also the customer's responsibility.

• Question 589:

  A company needs to set a maximum spending limit on AWS services each month. The company also needs to set up alerts for when the company reaches its spending limit.

  Which AWS service or tool should the company use to meet these requirements?

  A. Cost Explorer
  B. AWS Trusted Advisor
  C. Service Quotas
  D. AWS Budgets
  D. AWS Budgets

  ---

  Explanation

  AWS Budgets is a service that helps you plan your service usage, service costs, and instance reservations, and track how close your plan is to your budgeted amount. You can set custom budgets that alert you when you exceed (or are forecasted to exceed) your budgeted thresholds. You can also use AWS Budgets to set a maximum spending limit on AWS services each month and set up alerts for when you reach your spending limit. Cost Explorer is a service that enables you to visualize, understand, and manage your AWS costs and usage over time. You can use Cost Explorer to view charts and graphs that show how your costs are trending, identify areas that need further inquiry, and see the impact of your cost management actions. However, Cost Explorer does not allow you to set a maximum spending limit or alerts for your AWS services. AWS Trusted Advisor is a service that provides you real time guidance to help you provision your resources following AWS best practices, including security and performance. It can help you monitor for cost optimization opportunities, such as unused or underutilized resources, but it does not allow you to set a maximum spending limit or alerts for your AWS services. Service Quotas is a service that enables you to view and manage your quotas, also referred to as limits, from a central location. Quotas, also referred to as limits, are the maximum number of resources that you can create in your AWS account. However, Service Quotas does not allow you to set a maximum spending limit or alerts for your AWS services.
