- Analytics will not be able to associate user behavior data with past data collected.
- Analytics will set a new unique ID the next time a browser loads a tracked page.
- Analytics will set a new browser cookie the next time a browser loads a tracked page.
- All of the above.
The correct answer: All of the above
Explanation:

For Google Analytics to determine that two distinct hits belong to the same user, a unique identifier associated with that particular user must be sent with each hit.
Using cookies allows analytics.js to identify unique users across browsing sessions but cannot identify unique users across different browsers or devices.
