Question 55
A solutions architect is creating a multi-tier application that includes loosely-coupled, distributed application components and needs to determine a method of sending notifications instantaneously. Using Amazon SNS, which transport protocols are supported? (Select TWO)
- Amazon SWF
- FTP
- HTTPS
- AWS Lambda
- Email-JSON
Correct Answer: 3, 5
Explanation: Note that the question asks you which transport protocols are supported, and not which subscribers. Therefore, AWS Lambda is not supported.
Amazon SNS supports notifications over multiple transport protocols:
- HTTP/HTTPS: Subscribers specify a URL as part of the subscription registration.
- Email/Email-JSON: Messages are sent to registered addresses as email (text-based or JSON-object).
- SQS: Users can specify an SQS standard queue as the endpoint.
- SMS: Messages are sent to registered phone numbers as SMS text messages.
