To resolve the VM2 routing issue, you should modify the IP configuration setting of the Azure network interface resource of VM2. This will ensure that VM2 can communicate with other resources in the virtual network.

Troubleshooting connectivity problems between Azure VMs involves several steps such as checking whether NIC is misconfigured, whether network traffic is blocked by NSG or UDR, whether network traffic is blocked by VM firewall, whether VM app or service is listening on the port and whether the problem is caused by SNAT1.

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.

To troubleshoot the issue with SRV2, you need to run the Get-MsolServicePrincipalCredential PowerShell cmdlet, which returns the credentials that are associated with a service principal in Azure AD. The service principal is an identity that represents an application or a service that interacts with Azure AD. In this case, the service principal is used by the NPS extension for Azure AD MFA to communicate with Azure AD and perform MFA requests. The credentials of the service principal include a certificate and a key that are used to authenticate the service principal to Azure AD. If the credentials are expired or invalid, the MFA requests will fail with a security token error. To resolve this issue, you need to renew the credentials of the service principal by using the New-MsolServicePrincipalCredential cmdlet.
