Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 247 discussion

Exam question from Amazon's AWS Certified Developer - Associate DVA-C02
Question #: 247
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

A company deploys a photo-processing application to an Amazon EC2 instance. The application needs to process each photo in less than 5 seconds. If processing takes longer than 5 seconds, the company’s development team must receive a notification.

How can a developer implement the required time measurement and notification with the LEAST operational overhead?

  • A. Create an Amazon CloudWatch custom metric. Each time a photo is processed, publish the processing time as a metric value. Create a CloudWatch alarm that is based on a static threshold of 5 seconds. Notify the development team by using an Amazon Simple Notification Service (Amazon SNS) topic.
  • B. Create an Amazon Simple Queue Service (Amazon SQS) queue. Each time a photo is processed, publish the processing time to the queue. Create an application to consume from the queue and to determine whether any values are more than 5 seconds. Notify the development team by using an Amazon Simple Notification Service (Amazon SNS) topic.
  • C. Create an Amazon CloudWatch custom metric. Each time a photo is processed, publish the processing time as a metric value. Create a CloudWatch alarm that enters ALARM state if the average of values is greater than 5 seconds. Notify the development team by sending an Amazon Simple Email Service (Amazon SES) message.
  • D. Create an Amazon Kinesis data stream. Each time a photo is processed, publish the processing time to the data stream. Create an Amazon CloudWatch alarm that enters ALARM state if any values are more than 5 seconds. Notify the development team by using an Amazon Simple Notification Service (Amazon SNS) topic.

Option C is incorrect. CloudWatch alarm should be triggered based on "each photo in less than 5 seconds" not "average"

Selected Answer: A
This approach directly leverages AWS services for monitoring and notification with minimal setup and maintenance. CloudWatch custom metrics can be used to track the processing time for each photo. A CloudWatch alarm can then be configured to trigger when any metric value exceeds the threshold of 5 seconds, sending a notification to the development team via an SNS topic.
