SAP-C02 Question #208: Real Exam Question with Answer & Explanation

Question

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.)

Options

• ADeploy the SQS queue with the Lambda function to other Regions.
• BSubscribe the SNS topic in each Region to the SQS queue.
• CSubscribe the SQS queue in each Region to the SNS topic.
• DConfigure the SQS queue to publish URLs to SNS topics in each Region.
• EDeploy the SNS topic and the Lambda function to other Regions.

Explanation

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
