How does Firebase Hosting deliver your web app to users?

Firebase Hosting is designed to serve web apps quickly and securely. What is the main way Firebase Hosting delivers your web app files to users?

A It stores your app files on Google's global servers and sends them directly to users via a fast content delivery network.

B It runs your app code on a virtual machine and streams the output to users in real time.

C It sends your app files to users only when they request them through a peer-to-peer network.

D It compiles your app files into a mobile app and sends it to users automatically.

💡 Hint

Think about how websites usually load fast from servers close to you.

Firebase Hosting uses a global content delivery network (CDN) to store and serve your web app files from servers near users. This makes loading fast and reliable.

What happens when you deploy a new version of your web app to Firebase Hosting?

After you deploy a new version of your web app to Firebase Hosting, what is the expected behavior for users visiting your site?

A Firebase sends an email to users to notify them about the new version.

B Users must clear their browser cache manually to see the new version.

C Users immediately see the new version because Firebase updates the files on all CDN servers globally.

D The new version is only available on the main server and not on CDN servers.

💡 Hint

Think about how hosting services keep your site updated everywhere.

Firebase Hosting updates all CDN servers globally so users get the latest version immediately when they visit your site.

❓ Architecture

advanced

Why does Firebase Hosting use a CDN for web apps?

Firebase Hosting uses a content delivery network (CDN) to serve web apps. Which of the following is the main architectural reason for this?

A To reduce latency by serving content from servers geographically closer to users.

B To run backend code faster by using edge computing.

C To store user data securely in encrypted databases.

D To convert web apps into native mobile apps automatically.

💡 Hint

Think about how distance affects loading speed.

Using a CDN reduces the physical distance between users and servers, lowering latency and speeding up content delivery.

❓ security

advanced

How does Firebase Hosting ensure secure delivery of web apps?

Firebase Hosting serves web apps securely. Which feature helps protect users by encrypting data between the server and their browser?

A Firewall rules that block all incoming traffic.

B Disabling all JavaScript in the hosted web app.

C User passwords stored in plain text for easy access.

D Automatic HTTPS with SSL/TLS certificates for all hosted sites.

💡 Hint

Think about how websites show a lock icon in the browser address bar.

Firebase Hosting automatically provides HTTPS with SSL/TLS certificates, encrypting data and protecting users from eavesdropping.

✅ Best Practice

expert

What is the best practice to optimize Firebase Hosting for fast web app delivery?

To make your web app load faster on Firebase Hosting, which practice should you follow?

A Upload large uncompressed images to reduce server load.

B Minify and compress your HTML, CSS, and JavaScript files before deploying.

C Disable caching so users always get fresh files from the server.

D Use only inline styles and scripts to avoid external file requests.

💡 Hint

Think about reducing file size to speed up downloads.

Minifying and compressing files reduces their size, making downloads faster and improving user experience.
