Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 505 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C02
Question #: 505
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A company is running an application on AWS to process weather sensor data that is stored in an Amazon S3 bucket. Three batch jobs run hourly to process the data in the S3 bucket for different purposes. The company wants to reduce the overall processing time by running the three applications in parallel using an event- based approach.
What should a solutions architect do to meet these requirements?

  • A. Enable S3 Event Notifications for new objects to an Amazon Simple Queue Service (Amazon SQS) FIFO queue. Subscribe all applications to the queue for processing.
  • B. Enable S3 Event Notifications for new objects to an Amazon Simple Queue Service (Amazon SQS) standard queue. Create an additional SQS queue for all applications, and subscribe all applications to the initial queue for processing.
  • C. Enable S3 Event Notifications for new objects to separate Amazon Simple Queue Service (Amazon SQS) FIFO queues. Create an additional SQS queue for each application, and subscribe each queue to the initial topic for processing.
  • D. Enable S3 Event Notifications for new objects to an Amazon Simple Notification Service (Amazon SNS) topic. Create an Amazon Simple Queue Service (Amazon SQS) queue for each application, and subscribe each queue to the topic for processing.

D. For the same combination of: event type (e.g. object create) and prefix (e.g. images/) you can only have one S3 Event rule • If you want to send the same S3 event to many SQS queues, use fan-out So,C is not possible and the second part of it does not make sense after first part is done. Moreover, 'subscribers' are for SNS not SQS as indicated by first 3 options.

New Questions A company has migrated a two-tier application from its on-premises data center to the AWS Cloud. The data tier is a Multi-AZ deployment of Amazon RDS for Oracle with 12 ТВ of General Purpose SSD Amazon Elastic Block Store (Amazon EBS) storage. The application is designed to process and store documents in the database as binary large objects (blobs) with an average document size of 6 MB. The database size has grown over time, reducing the performance and increasing the cost of storage. The company must improve the database performance and needs a solution that is highly available and resilient. Which solution will meet these requirements MOST cost-effectively?

Answer may be C. Check this link: https://aws.amazon.com/blogs/database/how-to-determine-if-amazon-dynamodb-is-appropriate-for-your-needs-and-then-plan-your-migration/ "DynamoDB can store binary items up to 400 KB, but DynamoDB is not generally suited to storing documents or images. A better architectural pattern for this implementation is to store pointers to Amazon S3 objects in a DynamoDB table"
