โœ“ Correct Answer & Explanation

Correct Answer

Use Cloud Shell's Web Preview feature on port 8080, which proxies traffic through Google's infrastructure with the developer's identity

Why This Answer Is Correct

Cloud Shell's built-in **Web Preview** allows you to proxy traffic from a specific port (e.g., 8080) through Google's infrastructure to your browser session. The preview URL is authenticated โ€” only the logged-in user can access it. This is ideal for testing web servers, APIs, or UIs running inside Cloud Shell without any public exposure or firewall rules. Ports 8080โ€“8084 are commonly used; others may also be available.
