Explanation:

In a Microsoft 365 E5 environment with Global Secure Access (Microsoft Entra Internet Access) deployed, to block users from accessing a specific website (for example, https://contoso.com ), the configuration process involves creating network, filtering, and security control components in sequence.
According to the Microsoft SC-300 Study Guide and official Microsoft Learn module "Configure Microsoft Entra Internet Access and Private Access", the required workflow is as follows:
* Create a remote network - This step establishes the connectivity fabric that links user devices (running the Global Secure Access client) with the Microsoft Entra Global Secure Access services. It defines network parameters and routes traffic through the Microsoft Entra inspection layer.
* Create a web content filtering policy - Within Microsoft Entra Internet Access, administrators can define filtering rules that control outbound web traffic. Here, you would add https://contoso.com as a blocked domain or URL category. This policy ensures that traffic destined for that domain is denied.
* Configure a security profile - Security profiles combine web content filtering policies, Conditional Access policies, and inspection settings. You then assign the security profile to the remote network or user group so the filtering rule applies to traffic from the enrolled devices.
These steps align with Microsoft's recommended process to "create a remote network, define filtering policy, and link via a security profile" for enforcing secure outbound access control through Global Secure Access.
