Exam AWS Certified Solutions Architect - Professional topic 1 question 864 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 864
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company runs a serverless application in a single AWS Region. The application accesses external URLs and extracts metadata from those sites. The company uses an Amazon Simple Notification Service (Amazon SNS) topic to publish URLs to an Amazon Simple Queue Service (Amazon SQS) queue. An AWS Lambda function uses the queue as an event source and processes the URLs from the queue. Results are saved to an Amazon S3 bucket.
The company wants to process each URL in other Regions to compare possible differences in site localization. URLs must be published from the existing Region.
Results must be written to the existing S3 bucket in the current Region.
Which combination of changes will produce multi-Region deployment that meets these requirements? (Choose two.)

  • A. Deploy the SQS queue with the Lambda function to other Regions.
  • B. Subscribe the SNS topic in each Region to the SQS queue.
  • C. Subscribe the SQS queue in each Region to the SNS topic.
  • D. Configure the SQS queue to publish URLs to SNS topics in each Region.
  • E. Deploy the SNS topic and the Lambda function to other Regions.

A & C First you create the SQS and Lambda in each region and then you subscribe the SQS queue to the SNS topic (there is no need to create antoher SNS topic in each region) https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-configure-subscribe-queue-sns-topic.html

A - Process URLs in other regions = Lambda + SQS as source >> B - After the above is complete send D - Wrong answer - URLs must be published from the existing region. E: Wrong answer - "Process in other regions" = lambda, but "urls must be published from existing region"

In other region. it is needed that SQS & Lambda. so, C&E is correct. A is not correct answerr. because, they say that "deploy SQS to other region with using Lambda"

AC - the company wants to process the URLs published through the same endpoint, so they are looking to a single SNS with cross-regional delivery but separate SQS + Lambda per region.
