Which tool is designed to track and analyze network traffic?

The correct choice, Google Analytics, is designed specifically to track and analyze network traffic, particularly for websites. It provides insights into various metrics such as user behavior, traffic sources, session duration, and page views. This tool is essential for understanding how users interact with a website, which pages are most popular, and where visitors are coming from, whether that's search engines, social media, or direct visits.

In contrast, OpenRefine is primarily a tool for data cleaning and transformation, making it effective for handling large datasets but not for network traffic analysis. Tableau is a powerful data visualization tool that can present data insights but relies on underlying data sources; it is not inherently a network traffic analysis tool. Excel, while capable of data analysis and manipulation, is limited in its ability to track live network traffic and provides less functionality than specialized tools like Google Analytics for this purpose.
