A company is building a marketing communications service that targets mobile app users. It must send confirmation messages via Short Message Service (SMS) and allow users to reply to those SMS messages. The company must retain the responses for one year for analysis. What should a solutions architect implement to meet these requirements?

Amazon Pinpoint is designed for targeted marketing communications, including sending SMS messages to mobile app users and handling replies. An Amazon Pinpoint journey allows for multi-step engagement, including sending messages and processing responses. Configuring Pinpoint to send events to an Amazon Kinesis data stream ensures that all message events, including replies, are captured and retained for a year for analysis, meeting the archiving requirement. Incorrect options: Amazon Connect is a contact center service, not primarily for outbound marketing SMS with reply handling and archiving. Amazon SQS is a message queuing service, not an SMS sending service. While it can queue messages, it doesn't directly send SMS or handle replies in this context. Amazon SNS can send SMS, but an SNS FIFO topic is for ordered message delivery, not specifically for two-way SMS communication with reply handling and integrated archiving of all events like Pinpoint.
