Which service provides high-quality text translation on demand?

• A. Amazon Translate
• B. AWS CLI
• C. Amazon SageMaker
• D. Amazon Textract

Answer: (A)

On-demand, high-quality text translation is provided by Amazon Translate. It’s a fully managed neural machine translation service designed to translate text between many languages quickly and accurately, with real-time and batch options that you can call directly from your applications via API. This makes it ideal for adding multilingual capabilities without building or maintaining your own translation infrastructure.

The other options don’t fit because the AWS CLI is just a command-line tool for managing AWS resources, not a translation service; SageMaker is a platform for building and deploying ML models (you could train a translation model there, but it isn’t a ready-made on-demand translation service); and Textract focuses on extracting text from documents rather than translating it.
