Answer: Allow inbound traffic on port 443 for the web tier from any IP., Permit the database tier to receive inbound traffic on port 1433 only from the web tier's security group.
To prioritize security for a two-tier web application, the following configurations should be made: 1. **Option A**: Configure the security group for the web tier to allow inbound traffic on port 443 (HTTPS) from any IP (0.0.0.0/0). This ensures that the web tier can accept secure connections from the internet. 2. **Option C**: Configure the security group for the database tier to allow inbound traffic on port 1433 (the default port for Microsoft SQL Server) from the security group of the web tier. This setup ensures that the database tier only accepts traffic from the web tier, enhancing security by restricting access to the database server.
