What is shadow traffic (dark launching) used for?
- ✓Correct answer: Mirroring real requests to a new version without using its replies
- 2Sending traffic only at night when fewer users are online

The new service sees production load and data shapes, and responses can be compared. Side effects (writes, emails) must be disabled for mirrored requests.
