Distributing resources across Availability Zones provides what benefit?

• A. It reduces regional latency.
• B. It eliminates the need for backups.
• C. It provides fault tolerance and higher availability.
• D. It increases single-point-of-failure risk.

Answer: (C)

Distributing resources across Availability Zones mainly boosts fault tolerance and higher availability. Availability Zones are separate data centers within a region, with isolated power, cooling, and networking. By running components in multiple AZs and using load balancers and replicated data, the system can keep operating even if one zone goes down. This reduces the risk of a single point of failure and helps ensure services remain reachable. Be aware that this setup doesn’t automatically reduce regional latency; cross‑AZ communication can introduce some extra latency and cost. Backups are still essential for data protection and aren’t eliminated by multi-AZ deployment. So the primary benefit is improved fault tolerance and availability.
