Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 76 discussion

The answer is D! Not A - Athena provides REST API to run queries and does not expose data points as asked in the question, read this link properly - https://aws.amazon.com/about-aws/whats-new/2017/05/amazon-athena-adds-api-cli-aws-sdk-support-and-audit-logging-with-aws-cloudtrail/ Not B because you cannot ingest and store data points using lambda. Not C because Quicksight is an analytics service, needs data as input D is the correct answer because - 1. it can ingest data and not only store the data points but can expose them as REST API, here is a tutorial - https://docs.aws.amazon.com/apigateway/latest/developerguide/integrating-api-with-aws-services-kinesis.html

A is correct if you consider the requirements against each solution:- Need to store data points for analysis, and only Ans:A (S3) and Ans:C (redshift) have a storage component mentioned, so that rules out B and D Also the company wants to use these data points in its own existing analytics platform - means no analystics required in AWS soution, so D is wrong C mentions QuickSight which is used for creating dashboards, which is not required so can rule that out also Need to query the data which is stored in S3 so that it can be analysed by the companies own analystics tool, which is what Athena does from S3 using SQL..Athena is an interactive query service, not an analystics platform, so it will extract data from S3 ready for post analysis The data points should be accessible from REST API, which is possible for Athena ( https://aws.amazon.com/about-aws/whats-new/2017/05/amazon-athena-adds-api-cli-aws-sdk-support-and-audit-logging-with-aws-cloudtrail/ )

Folks going around emphasizing the word "storage" and then go ahead with B which has nothing to do with it. Lol. API gateway and AWS Lambda are both not storage option. If you really want to follow how the question is worded, S3 for storage and Athena for retrieval.

the already have existing analytics platform.

the key word is rest api

D is the correct

I vote B

I think it'sD https://aws.amazon.com/solutions/implementations/aws-streaming-data-solution-for-amazon-kinesis/

Answer is D

I don't know why D is correct ? "The business intends to incorporate these data points into its current analytics platform" is mentioned in quesiton. Why ask them to use KDA again ? I still realize the B is better in here.

A,C and D have their own analytics solution and user has their own analytics solution, so based on elimination, must be B

Keyword: Data points in its existing analytics platform + Data points must be accessible from the REST API + Track the location of its bicycles during peak operating hours They already have an analytics platform, A (Athena) and D (Kinesis Data Analytics) are out of the race even tough S3 & APT Gateway Support REST API. Now B and C are in Race. C will not support REST API. So answer should be B as per below details. Now if we talk about data type, we are talking about GEO location data for their bicycles. API Gateway will be support REST API. So, exact solution should be API Gateway with AWS Lambda along with Amazon Kinesis Data Analytics (Assume its used already).

The answer is D!

The answer is D!

If REST API means, there API gateway should be there.

When they ask for "storage and retrieval" they're not necessarily asking for a storage solution. In my opinion, this is a badly worded question, and based on how you interpret this, it could lead you astray. However, I'm going D.

B is correct.
