  A. AWS Lambda

  B. Amazon EC2

  C. AWS CodeDeploy

  D. AWS Wavelength

  Correct Answer: B

  B. Amazon EC2

  Amazon Elastic Compute Cloud (EC2) is a service that provides resizable compute capacity in the cloud. It is a good fit for workloads that require a significant amount of processing power, such as data processing. With EC2, the company can easily launch virtual machines with the required resources to complete the data processing within the 5 hours window. Additionally, the company can use Auto Scaling and Elastic Load Balancing to automatically scale the number of instances based on the workload, which can help to ensure that the data processing completes on time.

  AWS Lambda is a serverless compute service that runs your code without provisioning or managing servers. It's useful for event-driven and short-lived workloads that require less computational power than data processing workloads.

  AWS CodeDeploy is a service that automates code deployments to EC2 instances or on-premises instances.

  AWS Wavelength is a service that enables developers to build and run applications on the edge, closer to customers and end-users, using 5G networks.

  D. Amazon Simple Queue Service (Amazon SQS)

  Correct Answer: A

  Amazon Simple Notification Service (Amazon SNS) is a fully managed messaging service for both application-to-application (A2A) and application-to-person (A2P) communication.

  The A2A pub/sub functionality provides topics for high-throughput, push-based, many-to-many messaging between distributed systems, microservices, and event-driven serverless applications. Using Amazon SNS topics, your publisher systems can fanout messages to a large number of subscriber systems including Amazon SQS queues, AWS Lambda functions and HTTPS endpoints, for parallel processing, and Amazon Kinesis Data Firehose. The A2P functionality enables you to send messages to users at scale via SMS, mobile push, and email.
