GCP Cloud Digital Leader Practice Question

A media startup plans to launch a global video-streaming service. Executives want end users on every continent to experience low-latency playback without the company building or managing new data centers or contracting multiple Internet carriers. How does Google Cloud's global private network directly help meet this goal?

Customers establish VPN tunnels to each Google Cloud region so traffic bypasses the public Internet and guarantees performance.
Google automatically deploys identical virtual machines in every region at no extra cost, eliminating the need for new data centers.
User requests are carried over Google's own high-capacity global fiber backbone from the nearest edge point to the service, minimizing hops and latency.
Google temporarily leases additional public Internet bandwidth during traffic spikes to speed up content delivery worldwide.

Answer Description

Google owns and operates one of the world's largest private fiber backbones, interconnecting its data centers and more than 180 network edge locations. When user traffic enters the Google network at the nearest edge point, it stays on this high-capacity, privately managed infrastructure for as much of the journey as possible. Fewer unpredictable public-Internet hops and intelligent routing reduce latency and improve reliability for end users-all without the customer having to deploy or manage additional facilities or carrier contracts. The other options do not describe this capability: automatic VM replication across all regions is not provided by default, VPN tunnels are not required for public access, and leasing public Internet bandwidth does not deliver the same performance or control benefits.
