AWS Certified Big Data – Specialty — Question 1

A companys social media manager requests more staff on the weekends to handle an increase in customer contacts from a particular region. The company needs a report to visualize the trends on weekends over the past 6 months using QuickSight.
How should the data be represented?

Answer options

• A. A line graph plotting customer contacts vs. time, with a line for each region
• B. A pie chart per region plotting customer contacts per day of week
• C. A map of regions with a heatmap overlay to show the volume of customer contacts
• D. A bar graph plotting region vs. volume of social media contacts

Correct answer: C

Explanation

The correct answer is C because a heatmap overlay on a map effectively visualizes the density of customer contacts across different regions, making it easy to identify trends. Options A and D do not provide a regional focus, while option B shows daily data rather than the overall trends on weekends.
