Exam AWS Certified Data Analytics - Specialty topic 1 question 59 discussion

Exam question from Amazon's AWS Certified Data Analytics - Specialty
Question #: 59
Topic #: 1
[All AWS Certified Data Analytics - Specialty Questions]

An online retail company with millions of users around the globe wants to improve its ecommerce analytics capabilities. Currently, clickstream data is uploaded directly to Amazon S3 as compressed files. Several times each day, an application running on Amazon EC2 processes the data and makes search options and reports available for visualization by editors and marketers. The company wants to make website clicks and aggregated data available to editors and marketers in minutes to enable them to connect with users more effectively.
Which options will help meet these requirements in the MOST efficient way? (Choose two.)

  • A. Use Amazon Kinesis Data Firehose to upload compressed and batched clickstream records to Amazon OpenSearch Service (Amazon Elasticsearch Service).
  • B. Upload clickstream records to Amazon S3 as compressed files. Then use AWS Lambda to send data to Amazon OpenSearch Service (Amazon Elasticsearch Service) from Amazon S3.
  • C. Use Amazon OpenSearch Service (Amazon Elasticsearch Service) deployed on Amazon EC2 to aggregate, filter, and process the data. Refresh content performance dashboards in near-real time.
  • D. Use OpenSearch Dashboards (Kibana) to aggregate, filter, and visualize the data stored in Amazon OpenSearch Service (Amazon Elasticsearch Service). Refresh content performance dashboards in near-real time.
  • E. Upload clickstream records from Amazon S3 to Amazon Kinesis Data Streams and use a Kinesis Data Streams consumer to send records to Amazon OpenSearch Service (Amazon Elasticsearch Service).

OpenSearch can ingest from KDF and results not in real-time but in minutes, as such, KDF can still be used.

Correct answers are A & D as Kinesis Data Firehose can be used for data ingestion with its micro batching to push the data directly to Elastic Search. Kibana can be used for visualization. Options B, C & E are wrong as they are not the MOST efficient way.

KDF can ingest that data directly to Opensearch ( Still KDF has 60 sec buffer time, they want results in minutes. so this is fine). Choose opensearch dashboards for visualization when it comes to time-sensitive. here, some people choosing B over A. My explanation why we can ignore B is - they want result in minutes not real-time. So KDF is sufficient and will replace the whole process of streaming the data to s3 and then loading the data to OpenSearch via lambda.

"in minutes" - this is the key here. Always choose OpenSearch over Athena+Quicksight, in case of time sensitivity.

B and D. (Reason for B as opposed to A: Firehose has minimum 1 min delay. Lambda will be "instantly". Question )

B and D. AWS Lambda can be triggered for s3 events generated while copying to s3. And then it loads to OpenSearch in near real time. Then use Kibana for visualization and search requirement.

A, D most efficient and direct to destination. B instead of A feasible but uses S3. But qn also says data stored in S3 - assume for the best approach to A, D
