Which of the following best describes how cookies support analytics tools?

• A. They store personal data permanently on the device in plaintext.
• B. They track only the pages visited without session data.
• C. They require user consent in all cases to collect any data.
• D. They keep a record of user sessions and device information, enabling the collection of session start and traffic source data.

Answer: (D)

Cookies let analytics tools stitch together a visitor’s journey by storing small bits of data in the browser. The best description is that cookies keep a record of user sessions and device information, enabling the collection of session start and traffic source data. This means the analytics tool can see when a session begins, how long it lasts, which pages are viewed, and where the visitor came from, so it can attribute traffic and measure engagement.

Storing personal data permanently in plaintext isn’t how analytics cookies typically operate, and they can be session-based or persistent without exposing sensitive information. Cookies aren’t limited to just pages visited without session context, since session data is crucial for understanding user behavior across a visit. While consent practices matter for privacy, they aren’t universally required in all cases, but analytics benefits come from capturing session and source data as described.
