According to Microsoft Azure’s troubleshooting documentation, one of the steps to troubleshoot backup failures on Azure virtual machines is to check the Azure VM Guest Agent service health. You should ensure that the Azure VM Guest Agent service is started and up-to-date 1. On a Windows VM, you can navigate to services.msc and ensure that the Windows Azure VM Guest Agent service is up and running. Also, ensure that the latest version is installed 2

when you use Azure Site Recovery to replicate on-premises VMs that run in SCVMM, you need to check the SCVMM debug log for any errors or warnings related to replication. The SCVMM debug log is located at %SYSTEMDRIVE%\ProgramData\VMMLogs\SCVMM.debugtrace.log on the SCVMM server.

To troubleshoot the issue reported by Blue Yonder Airlines, you need to review the IKEDiagnosticLog, which contains information about the Internet Key Exchange (IKE) protocol that is used to establish IPsec VPN connections. The IKEDiagnosticLog can help you identify the cause of the VPN disconnections and IPsec failure to connect errors, such as mismatched authentication parameters, incorrect pre-shared keys, or network connectivity issues. You can enable and download the IKEDiagnosticLog from the Azure portal or by using PowerShell commands

The error 8344 insufficient access rights to perform the operation indicates that the Azure AD Connect service account does not have the required permissions to synchronize the Admin1 account. This could be because the Admin1 account is in an organizational unit (OU) that has security inheritance disabled, which prevents the service account from inheriting the necessary permissions from the parent OU. To resolve this issue, you should enable security inheritance in AD DS for the OU that contains the Admin1 account. This will allow the service account to synchronize the Admin1 account to Azure AD. Alternatively, you could also grant the service account explicit permissions on the Admin1 account, but this would be more tedious and less scalable than enabling security inheritance.

To resolve the issue reported by Admin2, you need to disassociate NSG5 from NIC4, which is the network interface of VM4. NSG5 is a network security group that has an inbound security rule that denies traffic from ASG2 to ASG5 over port 80. This rule prevents Admin2 from connecting to the web server public IP address on VM4 from VM2, as VM2 is in ASG2 and VM4 is in ASG5. By disassociating NSG5 from NIC4, you can remove the rule that blocks the traffic and allow Admin2 to access the web server on VM4. Alternatively, you could also modify or remove the rule in NSG5, but disassociating NSG5 from NIC4 is simpler and more effective.

To resolve the issue where a user reports an error message stating “A certificate could not be found” when trying to connect to an Azure point-to-site VPN that uses certificate-based authentication, you should perform the following three actions: B. Install a root certificate on the user’s device. F. Generate a client certificate. G. Install a client certificate on the user’s device.

Azure point-to-site VPNs that use certificate-based authentication require both a root certificate and a client certificate to be installed on the user’s device. The root certificate is used to validate the identity of the VPN gateway, while the client certificate is used to authenticate the user. If either of these certificates is missing or invalid, the user will not be able to connect to the VPN and may receive an error message stating that a certificate could not be found.

To resolve the issue with VM10, you need to remove the inbound security rule that has a priority of 100 in NSG10, which is blocking ICMP traffic from ASG1 to ASG10. The rule has a source of Any, a destination of VirtualNetwork, a protocol of ICMP, and an action of Deny. This means that any ICMP traffic from outside the VNet4 address space will be denied by NSG10, which is attached to subnet4. This prevents VM1 from pinging VM10 by using ICMP, as VM1 is in VNet1 and not in VNet4. By removing this rule, you can allow ICMP traffic from ASG1 to ASG10, as there is no other rule in NSG10 that explicitly denies it. Alternatively, you could also modify the rule to change the source to VirtualNetwork or the action to Allow, but removing the rule is simpler and more effective.

JIT VM access is only supported for VMs that are deployed using the Azure Resource Manager (ARM) deployment model. VMs that are provisioned using the classic deployment model are not compatible with JIT VM access and will be displayed under the Unsupported tab of the JIT VM access page in the Microsoft Defender for Cloud portal.

This will ensure that the route table RT12, which has a route to direct internet traffic to the virtual network gateway VNG1, is applied to the subnet where VM1 is located. This will override the default route that sends internet traffic to the internet gateway.

To resolve the issue, you should complete the CLI command as follows:

az role assignment create – assignee contoso-object-id --role “Owner” --scope

This command assigns the Owner role to the service principal with the object ID of contoso-object-id at the specified scope. The Owner role grants full access to all resources, including the right to assign roles to others1. The assignee parameter specifies the security principal to assign the role to2. The scope parameter specifies the level of access for the role assignment, such as a resource group or a subscription3.

To resolve the connectivity issues, you need to redeploy the ILB using the Standard SKU. According to 1, Basic Load Balancer does not support Global VNet Peering, which is required for cross-region communication between VMs in different VNets. Standard Load Balancer supports Global VNet Peering and can load balance traffic across regions and availability zones.

The solution does not meet the goal. Enabling replication and creating a recovery plan for the backup vault is not relevant to troubleshooting an Azure VM backup job failure. The administrator should troubleshoot the issue by checking the VM's disk configuration, checking the status of the VM guest agent, and ensuring that the backup policy is configured correctly.

To troubleshoot the cause for the VPN disconnections between VNetGW1 and the partner site, you should verify that the partner’s VPN device and VNetGW1 are configured using the same shared key. 

the two pieces of information that should be collected before starting to troubleshoot the failing synchronization by using a built-in Azure AD Connect troubleshooting task are: B. AD connector name E. Object distinguished name

Azure AD Connect is a tool used to synchronize users from an on-premises Active Directory Domain Services (AD DS) to Azure AD. When troubleshooting synchronization issues, it is important to have information about the object that is failing to synchronize. The AD connector name refers to the name of the connector used to connect to the on-premises AD DS. The object distinguished name refers to the unique identifier of the object in the on-premises AD DS. Having this information can help identify and resolve synchronization issues.

Location in Azure: B. Get-AzVirtualNetworkGateway

Location on Client Computer: D. ipconfig /all

To troubleshoot the issues reported by User1, you need to use the Get-AzVirtualNetworkGateway PowerShell cmdlet in Azure and the ipconfig /all command on the client computer. The Get-AzVirtualNetworkGateway cmdlet returns information about the virtual network gateways in a subscription or a resource group. You can use this cmdlet to verify the status and configuration of the VNetGW virtual network gateway, which provides point-to-site VPN connectivity for User1. The ipconfig /all command displays the IP configuration information for all network adapters on the client computer. You can use this command to check the IP address, subnet mask, default gateway, and DNS servers assigned to User1 when connected to the point-to-site VPN. This can help you identify any misconfiguration or connectivity issues that affect User1’s access to Azure resources.

Audit Logs

Azure AD connect logs

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.

To resolve the problem reported by User2, you need to assign an Azure AD Premium P1 license to User2. User2 is a member of the warehouse group, which is enabled for the self-service password reset (SSPR) feature. However, User2 cannot register for SSPR because they do not have a valid license that supports SSPR. To use SSPR, a user must have one of the following licenses: Azure AD Premium P1, Azure AD Premium P2, Enterprise Mobility + Security (EMS) E3 or EMS E5. By assigning an Azure AD Premium P1 license to User2, you can enable them to use the SSPR feature and reset their password without contacting the helpdesk
