Which of the following options can be used to protect Azure resources like storage accounts and Azure Cosmos DB?

The choice indicating "All of the above" is correct because each of the options listed plays a significant role in securing Azure resources like storage accounts and Azure Cosmos DB.

Using Azure Private Endpoint establishes a private connection between your resources and Azure services without needing to route traffic over the public internet. This enhances security by reducing exposure to the public, making it more difficult for unauthorized users to access your data.

Configuring Advanced Security is another layer of protection for your Azure resources. This option provides additional security features such as threat detection, security alerts, and recommendations to enhance the security posture of your Azure services.

Firewalls and Virtual Networks are fundamental security measures that can be employed to control access to Azure resources. Firewalls can restrict or permit traffic to and from specific IP addresses, while Virtual Networks can segment resources, allowing for secure communication within the Azure cloud environment. This ensures data integrity and confidentiality by controlling inbound and outbound traffic.

When combined, these security measures create a multi-layered defense approach, effectively protecting Azure resources from various security threats. Each of the options contributes uniquely to a comprehensive protection strategy, which is why "All of the above" is the accurate selection.
