Which services should the Solutions Architect use to build this solution?

Explanations:

Amazon Connect is a cloud-based contact center solution that allows the creation of contact flows and can scale to handle growth. It is ideal for receiving calls and handling customer interactions.

AWS Lambda is used to run backend logic and integrate with internal systems. It can query business applications and provide relevant information to the callers, which is a key requirement.

Amazon Lex provides deep learning-based natural language understanding to recognize the intent of callers. It can be used to handle basic tasks and reduce the need for human agents.

Amazon Rekognition is a computer vision service for image and video analysis, not suited for identifying callers. It is not relevant for this use case of handling voice calls in a contact center.

Amazon Alexa for Business is designed for building voice-based interfaces for workplace tasks, not for building a call center solution that recognizes intent or integrates with internal systems.

Amazon SQS is a message queuing service and isn’t directly designed for managing incoming calls in a contact center. It could be used for asynchronous processing but isn’t the core component for a real-time call handling solution.
