Recommended Azure Solution: Virtual Network

B

Networks in Azure are known as virtual networks. A virtual network can have multiple IP address spaces and multiple subnets. Azure automatically routes traffic between different subnets within a virtual network.

The question states that FinServer must be on a separate network segment. The only way to separate FinServer from the other servers in networking terms is to place the server in a different virtual network to the other servers.

The correct answer is B. A virtual network for FinServer and another virtual network for all the other servers.

Explanation: Azure Virtual Network is a service that enables you to create logically isolated networks in Azure. Each virtual network can contain multiple subnets, and you can create multiple virtual networks in the same Azure region or across different regions. By using virtual networks, you can create different network segments for different purposes, such as isolating FinServer from other servers for compliance purposes.

Option A (a resource group for FinServer and another resource group for all the other servers) is incorrect because resource groups are logical containers for Azure resources, and they do not provide network isolation. Creating separate resource groups for FinServer and other servers may help with resource management, but it does not meet the compliance policy requirements for network isolation.

Option C (a VPN for FinServer and a virtual network gateway for each other server) is also incorrect because a VPN (Virtual Private Network) provides secure connectivity between on-premises networks and Azure virtual networks, but it does not provide network isolation within Azure. In addition, creating a virtual network gateway for each other server is not practical and would be cost-prohibitive.

Option D (one resource group for all the servers and a resource lock for FinServer) is incorrect because a resource lock is used to prevent accidental deletion or modification of Azure resources, but it does not provide network isolation.

In summary, creating separate virtual networks for FinServer and other servers is the most practical and cost-effective way to meet the compliance policy requirements for network isolation in Azure.

The cloud model described in this scenario is a hybrid cloud model, which is option A.

In a hybrid cloud model, an organization uses a combination of on-premises infrastructure and cloud-based resources. This allows the organization to take advantage of the benefits of both models, while also addressing any limitations or concerns.

In the scenario described, there are both on-premises virtual machines and virtual machines hosted in Azure. These virtual machines are connected to each other, which means that they are able to communicate and share data. This hybrid model allows the organization to take advantage of the scalability and flexibility of cloud-based resources, while also maintaining control over their on-premises infrastructure.

Option B, private cloud, refers to a cloud environment that is used exclusively by a single organization. This is not the case in the scenario described, as the organization is using both on-premises infrastructure and Azure resources.

Option C, public cloud, refers to a cloud environment that is available to the general public. While the organization in the scenario is using Azure, which is a public cloud provider, the fact that they are also using on-premises infrastructure means that this is not a purely public cloud model.

In summary, the cloud model described in the scenario is a hybrid cloud model, which involves using a combination of on-premises infrastructure and cloud-based resources.
