Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 36 discussion

Answer is C because the limit you are referring to has now been removed, FIFO can now subscribe to SNS “ “SQS” – Users can specify an SQS standard or FIFO queue as the endpoint; Amazon SNS will enqueue a notification message to the specified queue” https://aws.amazon.com/sns/faqs/?nc1=h_ls

What is the default TTL for SQS? The default is 4 days. Once the message retention quota is reached, your messages are automatically deleted. MessageRetentionPeriod – The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer representing seconds, from 60 (1 minute) to 1,209,600 (14 days)

+1 on A; C cannot be correct as SNS does not guarantee ordering, if it were an SNS FIFO topic then that would've been correct, but just SNS topic will not guarantee ordering

Lambda is compatible with FIFO of the SQS queues; You can use an AWS Lambda function to process messages in an Amazon Simple Queue Service (Amazon SQS) queue. Lambda event source mappings support standard queues and first-in, first-out (FIFO) queues. With Amazon SQS, you can offload tasks from one component of your application by sending them to a queue and processing them asynchronously. Lambda polls the queue and invokes your function synchronously with an event that contains queue messages. Lambda reads messages in batches and invokes your function once for each batch. When your function successfully processes a batch, Lambda deletes its messages from the queue. The following example shows an event for a batch of two messages. https://docs.aws.amazon.com/lambda/latest/dg/with-sqs.html

Q: What are the different delivery formats/transports for receiving notifications? “SQS” – Users can specify an SQS standard or FIFO queue as the endpoint; Amazon SNS will enqueue a notification message to the specified queue (which subscribers can then process using SQS APIs such as ReceiveMessage, DeleteMessage, etc.).

bro you didn't read your own link. wtf with you people. Answer is C.

Is SNS compatible with SQS FIFO? You can now use Amazon Simple Notification Service (Amazon SNS) FIFO topics, in combination with Amazon Simple Queue Service (Amazon SQS) FIFO queues, to build applications that require messages to be sent and processed in a strict sequence and without duplicates.

Wrong!!!! An SQS queue does not guarantee processing with little latency
