Exam AWS Certified Cloud Practitioner topic 1 question 154 discussion

I think it's A

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.

Correct A. Amazon Simple Notification Service (Amazon SNS) sends SMS for mobile phones , email notifcation , push notifications and application to application(A2A) messaging via Amazon SQS , AWS Lamda or HTTP endpoints B. Amazon Simple Email Service (Amazon SES) -> send and receiving emails only C. Amazon CloudWatch alerts > montioner AWS resources and sending Alerts via SNS D. Amazon Simple Queue Service (Amazon SQS) >> queuing Service used for asynchronous processing between distrubted systems , it doesn't send emails and SMS

Amazon Simple Notification Service (Amazon SNS) is the AWS service used to send both text (SMS) and email messages from distributed applications. It is a fully managed communication service that allows you to send messages or notifications to a distributed set of recipients, including email addresses, mobile phone numbers (via SMS), Amazon SQS queues, Lambda functions, and more. Amazon SNS supports multiple communication protocols, including SMS, email, HTTP/S, and more, making it a versatile solution for sending messages across various channels.

Amazon Simple Notification Service (Amazon SNS) sends notifications in two ways: A2A and A2P. The A2A way provides high-throughput, push-based messaging for messaging between diverse distributed systems, microservices, and event-driven serverless applications. These applications include Amazon Simple Queue Service (SQS), Amazon Kinesis Data Firehose, AWS Lambda, and other HTTPS endpoints. The A2P functionality, in turn, allows you to send messages to your customers using SMS texts, push notifications and email. by: https://aws.amazon.com/sns/

Answer is correct: D https://aws.amazon.com/getting-started/hands-on/send-messages-distributed-applications/

Amazon Simple Notification Service (Amazon SNS) is a fully managed messaging service that enables the sending of both text messages (SMS) and email messages from distributed applications. It provides a publish-subscribe model, allowing messages to be sent to multiple subscribers or endpoints simultaneously. With Amazon SNS, applications can send messages to a variety of endpoints, including email addresses, mobile devices (via SMS), AWS Lambda functions, HTTP endpoints, and more. It supports both text-based messages and email messages, making it a versatile solution for sending notifications, alerts, and other types of messages to users or systems. Amazon SQS is a message queue service that allows you to decouple microservices and distributed systems. SQS is a good option for storing messages that need to be processed later. However, it is not a good option for sending text or email messages.

I think the question compiler does not understand english. It says both text and email and obviously it should be for mobile also.

Amazon SNS is used for pub/sub messaging and sending notifications to multiple subscribers, Amazon SQS is used for reliable message queuing and decoupling application components, and Amazon SES is used for sending high-quality emails. The choice between these services depends on your specific use case and the requirements of your application.

alcording to this i think id D distributed applications - > SQS https://ably.com/topic/aws-sns-vs-sqs#:~:text=SNS%20is%20typically%20used%20for,1%20minute%20to%2014%20days).

i think A is right,as follows https://aws.amazon.com/sns/?nc2=type_a

SQS is used to decouple application components, not sent emails and texs. that is what SNS is designed to do. https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-difference-from-amazon-mq-sns.html

SNS is right answer. SQS is wrong as via SQS can't send email.
