AWS Certified Machine Learning – Specialty — Question 241

A company operates an amusement park. The company wants to collect, monitor, and store real-time traffic data at several park entrances by using strategically placed cameras. The company’s security team must be able to immediately access the data for viewing. Stored data must be indexed and must be accessible to the company’s data science team.

Which solution will meet these requirements MOST cost-effectively?

Answer options

• A. Use Amazon Kinesis Video Streams to ingest, index, and store the data. Use the built-in integration with Amazon Rekognition for viewing by the security team.
• B. Use Amazon Kinesis Video Streams to ingest, index, and store the data. Use the built-in HTTP live streaming (HLS) capability for viewing by the security team.
• C. Use Amazon Rekognition Video and the GStreamer plugin to ingest the data for viewing by the security team. Use Amazon Kinesis Data Streams to index and store the data.
• D. Use Amazon Kinesis Data Firehose to ingest, index, and store the data. Use the built-in HTTP live streaming (HLS) capability for viewing by the security team.

Correct answer: B

Explanation

Option B is the most cost-effective solution as it utilizes Amazon Kinesis Video Streams, which is specifically designed for real-time video data ingestion and offers built-in HLS for immediate viewing by the security team. Option A relies on Amazon Rekognition, which may incur additional costs and is not necessary for basic viewing requirements. Options C and D do not provide the most efficient method for real-time access and are more complex or costly than needed.
