Exam AWS-SysOps topic 1 question 849 discussion

Exam question from Amazon's AWS-SysOps
Question #: 849
Topic #: 1
[All AWS-SysOps Questions]

A company runs an image-processing application on a serverless infrastructure. Each processing job runs in a single AWS Lambda execution. A sysops administrator is tasked with ensuring there is enough capacity to run 500 simultaneous jobs even if other Lambda functions are being run for other applications.
The administrator has already increased service limits within the Region.
Which action should be taken?

  • A. Configure a dead-letter queue to retry any throttled executions
  • B. Modify the memory settings on the Lambda function to allow for 500 parallel executions
  • C. Move the image-processing logic to AWS Step Functions
  • D. Set the reserved concurrency for the image-processing Lambda function to 500

Looks like D The regional concurrency limit starts at 1,000. You can increase the limit by submitting a request in the Support Center console. To allocate capacity on a per-function basis, you can configure functions with reserved concurrency. Reserved concurrency creates a pool that can only be used by its function, and also prevents its function from using unreserved concurrency.

Selected Answer: D
Reserved concurrency is an AWS Lambda feature that allows you to set the maximum number of concurrent executions for a specific Lambda function. By setting the reserved concurrency to 500 for the image-processing Lambda function, you ensure that the function can handle up to 500 simultaneous executions concurrently.

D is Correct Lambda uses quotas to determine how many concurrent runs are allowed for the AWS account. However, if different functions are competing for this number, you can further define concurrent runs.

D. Not A because is irrelevant, relates to SQS and failure debugging. Not B because nothing to do with memory. Not C because step functions aren't even relevant.
