Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03

Question #: 40
Topic #: 1

[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company has thousands of edge devices that collectively generate 1 TB of status alerts each day. Each alert is approximately 2 KB in size. A solutions architect needs to implement a solution to ingest and store the alerts for future analysis.
The company wants a highly available solution. However, the company needs to minimize costs and does not want to manage additional infrastructure. Additionally, the company wants to keep 14 days of data available for immediate analysis and archive any data older than 14 days.
What is the MOST operationally efficient solution that meets these requirements?

A. Create an Amazon Kinesis Data Firehose delivery stream to ingest the alerts. Configure the Kinesis Data Firehose stream to deliver the alerts to an Amazon S3 bucket. Set up an S3 Lifecycle configuration to transition data to Amazon S3 Glacier after 14 days.
B. Launch Amazon EC2 instances across two Availability Zones and place them behind an Elastic Load Balancer to ingest the alerts. Create a script on the EC2 instances that will store the alerts in an Amazon S3 bucket. Set up an S3 Lifecycle configuration to transition data to Amazon S3 Glacier after 14 days.
C. Create an Amazon Kinesis Data Firehose delivery stream to ingest the alerts. Configure the Kinesis Data Firehose stream to deliver the alerts to an Amazon OpenSearch Service (Amazon Elasticsearch Service) cluster. Set up the Amazon OpenSearch Service (Amazon Elasticsearch Service) cluster to take manual snapshots every day and delete data from the cluster that is older than 14 days.
D. Create an Amazon Simple Queue Service (Amazon SQS) standard queue to ingest the alerts, and set the message retention period to 14 days. Configure consumers to poll the SQS queue, check the age of the message, and analyze the message data as needed. If the message is 14 days old, the consumer should copy the message to an Amazon S3 bucket and delete the message from the SQS queue.

Definitely A, it's the most operationally efficient compared to D, which requires a lot of code and infrastructure to maintain. A is mostly managed (firehose is fully managed and S3 lifecycles are also managed)

what about the 30 days minimum requirement to transition to S3 glacier?

This constraint is related to moving from Standard to IA/IA-One Zone only. Nothing to do with Glacier

You can directly migrate from S3 standard to glacier without waiting https://docs.aws.amazon.com/AmazonS3/latest/userguide/lifecycle-transition-general-considerations.html

No , It's not correct , We can change the storage class in day 0 also using lifecycle policy , I implemented in my project, 30 days is just an example.

Selected Answer: A

Only A makes sense operationally. If you think D, just consider what is needed to move the message from SQS to S3... you are polling daily 14 TB to take out 1 TB... that's no operationally efficient at all.

Use Amazon Kinesis Data Firehose to deliver alerts to Amazon S3, and configure S3 Lifecycle rules to transition older data to Glacier after 14 days — achieving the most efficient, scalable, and low-maintenance solution for this use case.

Using Kinesis Data Firehouse with S3 Life Configuration policies is the most suitable option as we are looking for less operational overhead.

I understand A is the most operationally efficient option of all but I can't wrap my head around the fact that objects must have a minimum of 30 days before they can transition or expire from Amazon S3. This means that for the first 30 days after an item is created, you cannot transition or remove it. So, how option A can be the best fit?

The same 30-day minimum applies when you specify a transition from S3 Standard-IA storage to S3 One Zone-IA. https://docs.aws.amazon.com/AmazonS3/latest/userguide/lifecycle-transition-general-considerations.html

But the docs are also mentioning a table with minimum storage durations beyond the S3 Standard-IA "[...]for a list of minimum storage duration for all storage class, see Comparing the Amazon S3 storage classes." https://docs.aws.amazon.com/AmazonS3/latest/userguide/storage-class-intro.html#sc-compare

That was an easy A. Kinesis Firehose can load data directly to S3 which makes it the most operationally efficient

Selected Answer: A

"A" is simply correct because kinesis firehouse is made for this, SQS standard is not going to support 500 million alerts 2KB each (1 TB) this service is made for requests that are lighter.
