Why do we use virtual hosting to serve multiple domains?

To save resources by using one server and IP address to handle many websites, making hosting efficient and cost-effective.

How does nginx know which website to serve when multiple domains use virtual hosting?

Nginx uses the 'server_name' directive to match the requested domain and serve the correct website content.

What is the difference between IP-based and name-based virtual hosting?

IP-based uses different IP addresses for each domain; name-based uses the same IP but distinguishes domains by their names.

How does virtual hosting relate to real-life apartment buildings?

Like one building with many apartments, virtual hosting lets one server host many websites, each with its own address (domain).

What directive does nginx use to serve different websites on the same server?

A server_name

B listen_port

C root_path

D proxy_pass

The 'server_name' directive tells nginx which domain name to respond to for each website.

Why is virtual hosting useful?

A It blocks unwanted domains.

B It allows hosting multiple domains on one server and IP address.

C It increases the server's IP addresses.

D It speeds up internet connection.

Virtual hosting lets one server handle many domains, saving resources and costs.

Which type of virtual hosting uses the same IP address for multiple domains?

A Port-based virtual hosting

B IP-based virtual hosting

C Name-based virtual hosting

D DNS-based virtual hosting

Name-based virtual hosting uses one IP address and distinguishes domains by their names.

If two domains share one IP address, how does nginx serve the correct site?

A By checking the domain name in the request header

B By using different ports

C By changing IP addresses dynamically

D By using different server hardware

Nginx reads the domain name sent by the browser to decide which site to serve.

What is a real-life example similar to virtual hosting?

A One car with many engines

B One book with many covers

C One phone number for many people

D One apartment building with many apartments

An apartment building hosts many apartments at one address, like one server hosting many domains.

Explain how virtual hosting allows one server to serve multiple websites.

Think about how nginx uses domain names to decide which website to show.

Describe the difference between IP-based and name-based virtual hosting.

Consider how the server identifies the website to serve.
