1.A company has a workflow that sends video files from their on-premise system to AWS for transcoding. They use EC2 worker instances that pull transcoding jobs from SQS. Why is SQS an appropriate service for this scenario?

A.SQS guarantees the order of the messages.

B.SQS synchronously provides transcoding output.

C.SQS checks the health of the worker instances.

D.SQS helps to facilitate horizontal scaling of encoding tasks.

Answer:D

SQS helps to facilitate horizontal scaling of encoding tasks.

Explanation:

Amazon SQS (Simple Queue Service) enables decoupling of components in distributed applications, allowing multiple EC2 worker instances to pull jobs concurrently.
This facilitates horizontal scaling, where multiple instances process tasks independently and in parallel, improving performance and fault tolerance.
SQS ensures that messages (transcoding jobs) are delivered and can be processed by available worker instances, ensuring scalability and reliability.
