Topic 1 Question 133
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?

2 つ選択
- Deploy the SQS queue with the Lambda function to other Regions.
- Subscribe the SNS topic in each Region to the SQS queue.
- Subscribe the SQS queue in each Region to the SNS topic.
- Configure the SQS queue to publish URLs to SNS topics in each Region.
- Deploy the SNS topic and the Lambda function to other Regions.

  Option A is correct because deploying the SQS queue with the Lambda function to other regions will allow the application to process URLs in those regions and compare differences in site localization.
  
  Option C is correct because subscribing the SQS queue in each region to the SNS topic in the existing region will allow the application to publish URLs to the existing SNS topic and have those URLs processed in other regions.
  
  Option B is incorrect because subscribing the SNS topic in each region to the SQS queue in the existing region would not allow URLs to be processed in other regions.
  
  Option D is incorrect because configuring the SQS queue to publish URLs to SNS topics in each region would not ensure that the URLs are processed in those regions.
  
  Option E is incorrect because deploying the SNS topic and Lambda function to other regions without the SQS queue would not allow the application to process URLs in those regions.
