A company is using a cloud provider to host a multi-tier application. The application has a web tier and a database tier. The security team requires that the database tier be accessible only from the web tier, not from the internet. The company has created a virtual network with two subnets: one for the web tier and one for the database tier. Which configuration should you implement?

Assign a public IP to the database server and use a firewall to restrict access to the web server's IP.

Use a network security group (NSG) on the database subnet that allows inbound traffic only from the web subnet's IP range.

Place the database server in the same subnet as the web server and rely on the web server's firewall to protect it.

Use a VPN to connect the database server to the web server.
