AWS Certified Big Data – Specialty — Question 52

A travel website needs to present a graphical quantitative summary of its daily bookings to website visitors for marketing purposes. The website has millions of visitors per day, but wants to control costs by implementing the least-expensive solution for this visualization.
What is the most cost-effective solution?

Answer options

• A. Generate a static graph with a transient EMR cluster daily, and store it an Amazon S3.
• B. Generate a graph using MicroStrategy backed by a transient EMR cluster.
• C. Implement a Jupyter front-end provided by a continuously running EMR cluster leveraging spot instances for task nodes.
• D. Implement a Zeppelin application that runs on a long-running EMR cluster.

Correct answer: A

Explanation

The correct answer, A, is the most cost-effective because generating a static graph with a transient EMR cluster minimizes ongoing costs and utilizes Amazon S3 for storage. Options B and C involve more complex setups and potential continuous costs, while D requires a long-running EMR cluster, which is less economical compared to the transient solution.
