Correct answer:
-
Amazon Polly converts text into lifelike speech, enabling applications to speak out loud.
It uses advanced deep learning technologies to synthesize natural-sounding human speech from text inputs.
Other options — why they're wrong:
-
Amazon Polly is primarily used for image recognition tasks.
This option is incorrect because Amazon Polly is not related to image recognition but rather to text-to-speech conversion.|
-
Amazon Polly is a data storage service for machine learning models.
This option is incorrect because Amazon Polly does not provide data storage; it is focused on converting text to speech.|
-
Amazon Polly is a tool for natural language processing in machine learning.
This option is incorrect as Amazon Polly is specifically a text-to-speech service, not a natural language processing tool.
Q146. How does AWS Data Pipeline assist with data movement and transformation?
Correct answer:
-
AWS Data Pipeline allows for the orchestration of data movement and transformation by scheduling data processing activities across various AWS services and on-premises data sources.
It helps automate the data workflow, ensuring data is regularly moved and transformed as per defined schedules and processes.
Other options — why they're wrong:
-
AWS Data Pipeline requires manual intervention for data movement and transformation tasks.
AWS Data Pipeline is designed to automate these processes, reducing the need for manual tasks.
-
AWS Data Pipeline only works with data stored in Amazon S3.
AWS Data Pipeline can work with multiple data sources, including RDS, DynamoDB, and on-premises data sources.
-
AWS Data Pipeline is exclusively used for data storage solutions.
AWS Data Pipeline is primarily focused on data orchestration, processing, and transformation, not just storage.
Q147. What are the key benefits of using AWS Outposts for hybrid cloud environments?
Correct answer:
-
Improved latency and performance
AWS Outposts brings AWS services to on-premises locations, reducing latency for local applications and improving overall performance.
Other options — why they're wrong:
