Question 1

A manufacturing company wants to create an operational analytics dashboard to visualize metrics from equipment in near- real time. The company uses Amazon Kinesis Data Streams to stream the data to other applications. The dashboard must automatically refresh every 5 seconds. A data analytics specialist must design a solution that requires the least possible implementation effort.Which solution meets these requirements?

A. Use Amazon Kinesis Data Firehose to store the data in Amazon S3. Use Amazon QuickSight to build the dashboard.
B. Use Apache Spark Streaming on Amazon EMR to read the data in near-real time. Develop a custom application for the dashboard by using D3.js.
C. Use Amazon Kinesis Data Firehose to push the data into an Amazon OpenSearch Service (Amazon Elasticsearch Service) cluster. Visualize the data by using an OpenSearch Dashboards (Kibana).
D. Use AWS Glue streaming ETL to store the data in Amazon S3. Use Amazon QuickSight to build the dashboard
Show Answer & Explanation

Correct Answer: C. Use Amazon Kinesis Data Firehose to push the data into an Amazon OpenSearch Service (Amazon Elasticsearch Service) cluster. Visualize the data by using an OpenSearch Dashboards (Kibana).

Why C is correct: Amazon Kinesis Data Firehose can directly push data into Amazon OpenSearch Service (formerly Elasticsearch Service), and OpenSearch Dashboards (formerly Kibana) provides native real-time visualization capabilities with automatic refresh intervals as low as 5 seconds. This is a fully managed solution requiring minimal implementation effort - you simply configure Firehose to deliver to OpenSearch and create dashboards in the OpenSearch Dashboards UI. Why others are wrong: A & D use QuickSight, which requires manual refresh and doesn't support automatic 5-second refresh intervals for streaming data B requires significant custom development effort with D3.js and managing EMR clusters, which violates the "least implementation effort" requirement

Question 2

An IoT company wants to release a new device that will collect data to track sleep overnight on an intelligent mattress. Sensors will send data that will be uploaded to an Amazon S3 bucket. About 2 MB of data is generated each night for each bed. Data must be processed and summarized for each user, and the results need to be available as soon as possible. Part of the process consists of time windowing and other functions. Based on tests with a Python script, every run will require about 1 GB of memory and will complete within a couple of minutes.Which solution will run the script in the MOST cost-effective way?

A. AWS Lambda with a Python script
B. AWS Glue with a Scala job
C. Amazon EMR with an Apache Spark script
D. AWS Glue with a PySpark job
Show Answer & Explanation

Correct Answer: A. AWS Lambda with a Python script

Why A is correct: AWS Lambda is the most cost-effective solution because it operates on a pay-per-execution model with no infrastructure costs when idle. With 1 GB memory requirement and couple-minute execution time per run, Lambda fits perfectly within its limits (up to 10 GB memory, 15 minutes timeout). Lambda natively supports Python, avoiding unnecessary conversion. Since data processing happens once per night per bed, Lambda's pricing model (charging only for actual compute time) is far more economical than continuously running clusters. Why others are wrong: B uses Scala instead of the existing Python script, requiring code conversion C EMR clusters are overkill for this simple processing task and incur costs even when idle D while AWS Glue supports PySpark, it's more expensive than Lambda for infrequent, short-duration jobs
