A financial services company stores financial data in Amazon Redshift. A data engineer wants to run real-time queries on the financial data to support a web-based trading application. The data engineer wants to run the queries from within the trading application.
Which solution will meet these requirements with the LEAST operational overhead?

  1. A. Establish WebSocket connections to Amazon Redshift.
  2. B. Use the Amazon Redshift Data API.
  3. C. Set up Java Database Connectivity (JDBC) connections to Amazon Redshift.
  4. D. Store frequently accessed data in Amazon S3. Use Amazon S3 Select to run the queries.
正解と解説を表示

正解

B

解説

The Amazon Redshift Data API is a lightweight, HTTPS-based API that provides an alternative to using JDBC or ODBC drivers for running queries against Amazon Redshift. It allows you to execute SQL queries directly from within your application without the need for managing connections or drivers. This reduces operational overhead as there's no need to manage and maintain WebSocket or JDBC connections.

Question#8Topic1

A company uses Amazon Athena for one-time queries against data that is in Amazon S3. The company has several use cases. The company must implement permission controls to separate query processes and access to query history among users, teams, and applications that are in the same AWS account.
Which solution will meet these requirements?

  1. A. Create an S3 bucket for each use case. Create an S3 bucket policy that grants permissions to appropriate individual IAM users. Apply the S3 bucket policy to the S3 bucket.
  2. B. Create an Athena workgroup for each use case. Apply tags to the workgroup. Create an IAM policy that uses the tags to apply appropriate permissions to the workgroup.
  3. C. Create an IAM role for each use case. Assign appropriate permissions to the role for each use case. Associate the role with Athena.
  4. D. Create an AWS Glue Data Catalog resource policy that grants permissions to appropriate individual IAM users for each use case. Apply the resource policy to the specific tables that Athena uses.

Question#10Topic1

A data engineer needs to create an AWS Lambda function that converts the format of data from .csv to Apache Parquet. The Lambda function must run only if a user uploads a .csv file to an Amazon S3 bucket.
Which solution will meet these requirements with the LEAST operational overhead?

  1. A. Create an S3 event notification that has an event type of s3:ObjectCreated:*. Use a filter rule to generate notifications only when the suffix includes .csv. Set the Amazon Resource Name (ARN) of the Lambda function as the destination for the event notification.
  2. B. Create an S3 event notification that has an event type of s3:ObjectTagging:* for objects that have a tag set to .csv. Set the Amazon Resource Name (ARN) of the Lambda function as the destination for the event notification.
  3. C. Create an S3 event notification that has an event type of s3:*. Use a filter rule to generate notifications only when the suffix includes .csv. Set the Amazon Resource Name (ARN) of the Lambda function as the destination for the event notification.
  4. D. Create an S3 event notification that has an event type of s3:ObjectCreated:*. Use a filter rule to generate notifications only when the suffix includes .csv. Set an Amazon Simple Notification Service (Amazon SNS) topic as the destination for the event notification. Subscribe the Lambda function to the SNS topic.

正解

A

解説

"only if a user uploads data to an Amazon S3 bucket" that excludes B & C because we need s3:ObjectCreated:* You don't need SNS for S3 event notifications.
