Box 1: Deploy an Azure virtual machine (VM) that hosts a DNS service.

In the given scenario, CosmosDB1 is an on-premises database, and you need to make it accessible by host name using VNet1. To achieve this, you should deploy an Azure virtual machine that hosts a DNS service. This will allow you to configure custom DNS settings for VNet1, enabling the resolution of the on-premises database's host name. Reference:

Box 2: Configure DNS conditional forwarding in the on-premises DNS infrastructure.

In the given scenario, you need to resolve the connectivity issue with the on-premises database named CosmosDB1, and it must be accessible by hostname from the on-premises environment. To achieve this, you should configure DNS conditional forwarding in the on-premises DNS infrastructure. DNS conditional forwarding allows you to specify that DNS queries for a specific domain (in this case, the Azure Cosmos DB) are forwarded to a specific DNS server or set of servers. This ensures that the on-premises environment can resolve the hostname of CosmosDB1 by forwarding the DNS queries to the appropriate DNS server responsible for that domain. References: 1. 2.

Box 1: Assign the Contributor role to the team members.

In the given scenario, the team members are unable to create or manage resources in the Azure portal. To allow them to do so, you should assign the Contributor role to the team members. The Contributor role allows users to create and manage resources within the scope of their access, but they cannot grant access to others. The Reader role only provides read access to resources and does not allow creation or management of resources. The Reader and Data Access role is not a valid combined role in Azure. Reference: - Azure built-in roles:

As mentioned in the scenario, the team members are unable to create resources in Azure Portal. This indicates that they do not have sufficient permissions to perform this operation. To grant them permissions, you need to assign them an Azure role that allows creating and managing Azure resources.

Azure roles are roles that can be assigned to users, groups, or applications to manage access to Azure resources1. Azure roles are based on Azure role-based access control (Azure RBAC), which is an authorization system that provides fine-grained access management of Azure resources2. With Azure RBAC, you can control access to resources by creating role assignments, which consist of three elements2:

• The security principal: The user, group, or application that you want to grant or deny access to the resource.
• The role definition: The predefined or custom set of permissions that you want to grant or deny on the resource. For example, read, write, delete, backup, restore, etc.
• The scope: The level at which you want to apply the role assignment. For example, at the management group, subscription, resource group, or individual resource level.

To assign an Azure role that allows creating and managing Azure resources, you can use the Contributor role. The Contributor role is a built-in role that has full access to all resources except granting access to others1. This means that users who are assigned the Contributor role can create and manage any type of Azure resource, such as virtual machines, storage accounts, web apps, etc.

To assign the Contributor role using the Azure portal, follow these steps3:

• In the Azure portal, navigate to the scope where you want to assign the role. For example, a subscription or a resource group.
• Select Access control (IAM), then select Add > Add role assignment.
• Under Role, select Contributor from the drop-down list.
• Under Assign access to, select User, group, or service principal.
• Under Select, find and select the users or groups that you want to assign the role to. You can type in the Select box to search the directory for display name or email address.
• Select Save to create the role assignment.

To assign the Contributor role using the Azure CLI or PowerShell, see Assign Azure roles using CLI or PowerShell.

Box 2: Assign the Storage Blob Data Contributor role to the team members. 

A detailed explanation with references is as follows:

As mentioned in the scenario, the team members are unable to perform backups and restores of blob data. This indicates that they do not have sufficient permissions to access blob storage resources. To grant them permissions, you need to assign them an Azure role that allows read/write/delete permissions to blob storage resources.

Azure roles are roles that can be assigned to users, groups, or applications to manage access to Azure resources2. Azure roles are based on Azure role-based access control (Azure RBAC), which is an authorization system that provides fine-grained access management of Azure resources3. With Azure RBAC, you can control access to resources by creating role assignments, which consist of three elements3:

• The security principal: The user, group, or application that you want to grant or deny access to the resource.
• The role definition: The predefined or custom set of permissions that you want to grant or deny on the resource. For example, read, write, delete, backup, restore, etc.
• The scope: The level at which you want to apply the role assignment. For example, at the management group, subscription, resource group, or individual resource level.

To assign an Azure role that allows read/write/delete permissions to blob storage resources, you can use the Storage Blob Data Contributor role. The Storage Blob Data Contributor role is a built-in role that has full access to blob storage resources except granting access to others1. This means that users who are assigned the Storage Blob Data Contributor role can perform backups and restores of blob data.

To assign the Storage Blob Data Contributor role using the Azure portal, follow these steps4:

• In the Azure portal, navigate to the scope where you want to assign the role. For example, a storage account or a container.
• Select Access control (IAM), then select Add > Add role assignment.
• Under Role, select Storage Blob Data Contributor from the drop-down list.
• Under Assign access to, select User, group, or service principal.
• Under Select, find and select the users or groups that you want to assign the role to. You can type in the Select box to search the directory for display name or email address.
• Select Save to create the role assignment.

To assign the Storage Blob Data Contributor role using the Azure CLI or PowerShell, see Assign Azure roles using CLI or PowerShell.

Box 1 =  Use IP flow verify.

IP flow verify is a feature of Azure Network Watcher that checks if a packet is allowed or denied to or from a virtual machine. It can help diagnose connectivity issues caused by network security groups, user-defined routes, or Azure Virtual Network Manager rules1. IP flow verify can also return the name of the rule that denied the packet, which can be useful for troubleshooting2.

Connection troubleshoot is another feature of Azure Network Watcher that helps reduce the time to diagnose and resolve network connectivity issues. However, it can only test TCP or ICMP connections from certain Azure resources, such as virtual machines, Azure Bastion instances, or application gateways3. Connection troubleshoot can also detect issues such as high VM CPU utilization, DNS resolution failures, or inability to open a socket at the specified source port3.

In this scenario, you need to collect the required logs for the SharePoint workload in VNet2. Since you are not testing a specific TCP or ICMP connection, but rather checking if packets are allowed or denied by any network configuration, IP flow verify is more suitable than connection troubleshoot. You can use IP flow verify to check the direction, protocol, local IP, remote IP, local port, and remote port of the packets and see which rule is blocking them12.

To use IP flow verify, you need to enable a network watcher in the same region as the virtual machines you want to troubleshoot. Then you can use the Azure portal, PowerShell, or Azure CLI to run IP flow verify and get the results24.

Box 2 =  Use Traffic analytics

To troubleshoot issues related to the SharePoint workload in VNet2, we can use Traffic Analytics. It is a networking monitoring solution that uses Network Watcher to analyze and report on traffic flows in your Azure virtual network. With Traffic Analytics, you could see information about the traffic flow patterns and security concerns detected across Azure subscriptions using network security group (NSG) flow logs. IP Flow Verify is used to verify if packets are flowing as expected between two endpoints within an Azure virtual network or between a public IP address and an endpoint inside an azure virtual network. But it doesn't provide visibility into overall traffic patterns or identify potential security threats. Connection Troubleshoot can be used when you have connectivity problems while interacting with a specific instance of a resource type being served out from Microsoft datacenters over Internet, but for troubleshooting SharePoint workloads related issue which might not necessarily correspond to internet routing/connectivity problems this may not apply.
