Question 51
A company has an ExpressRoute gateway between their on-premises site and Azure. The ExpressRoute gateway is on a virtual network named VNet1. The company enables FastPath on the gateway. You associate a network security group (NSG) with all of the subnets.
Users report issues connecting to VM1 from the on-premises environment. VM1 is on a virtual network named VNet2. Virtual network peering is enabled between VNet1 and VNet2. You create a flow log named FlowLog1 and enable it on the NSG associated with the gateway subnet.
You discover that FlowLog1 is not reporting outbound flow traffic.
You need to resolve the issue with FlowLog1.
What should you do?
According to 2, when FastPath is enabled on an ExpressRoute gateway, network traffic between your on-premises network and your virtual network bypasses the gateway and goes directly to virtual machines in the virtual network. Therefore, if you want to capture outbound flow traffic from VM1, you need to enable flow logging on an NSG associated with the subnet of VM1.

Question 53
A company has an Azure Active Directory (Azure AD) tenant. The company provisions an Azure Active Directory Domain Services (Azure AD DS) instance. Users report that they are unable to sign into Azure AD DS after being provisioned from Azure AD.
You verify the user accounts exist in Azure AD DS.
You need to resolve the issue.
What should you do?
Question 54
A company has users in Azure Active Directory (Azure AD). The company enables the users to use Azure AD multi-factor authentication (MFA). A user named User1 reports they receive the following error while setting up additional security verification settings for MFA:
Sorry! We can't process your request. Your session is invalid or expired. There was an error processing your request because your session is invalid or expired. Please try again. You need to help the user complete the MFA setup.
What should you do?
Question 55
A company has an Azure Active Directory (Azure AD) tenant. The company deploys Azure AD Connect to synchronize objects from their Active Directory Domain Services (AD DS) domain. You observe that AD DS objects are not synchronizing to Azure AD.
You need to verify that the staging mode is enabled.
What should you do?
Azure AD Connect has a staging mode feature that allows you to install multiple sync servers for high availability or disaster recovery purposes. When staging mode is enabled on a sync server, it doesn’t export any changes to Azure AD or your on-premises AD DS environment.
To verify that staging mode is enabled on a sync server, you can run the Get-ADSyncScheduler PowerShell cmdlet and check the value of StagingModeEnabled property. If it is True, then staging mode is enabled and no synchronization will occur.
Question 56
A company has on-premises application server that runs in System Center Virtual Machine Manager (SCVMM). The company configures Azure Site Recovery.
An administrator at the company reports that they receive an error message. The error message indicates that there are replication issues. You need to troubleshoot the issue.
Which log should you review?
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.
Question 57
A company uses Azure Site Recovery (ASR) for a VMware environment that includes the following virtual machines (VMs):
The company reports that they are unable to configure all of the servers for replication.
You need to evaluate the servers and server roles to determine which servers can be protected.
Which server can you protect by using ASR?
Azure Site Recovery supports replicating VMware VMs that meet certain requirements for operating system version, disk type and size, network adapter type and configuration, and so on. Based on the table of VMs and their properties, only VM1 meets all the requirements for replication
Question 58
A company uses Azure Site Recovery (ASR) to replicate and recover Azure virtual machines (VM) between Azure regions. An administrator receives the following warning from ASR about a VM that uses P10 disks: Data change rate beyond supported limits You add OS Disk Write Bytes/Sec and Data Disk Write Bytes/Sec to the list of metrics for monitoring. You discover that the VM consistently has a data churn of greater than 8 MB/s but less than 10 MB/s.
You need to resolve the issue.
What should you do?
Azure Site Recovery has limits on data change rates depending on the type of disk used for replication. If a VM has a data change rate higher than the supported limit for its disk type, it can cause replication issues or errors. To resolve this issue, you can upgrade the target storage disk to a higher tier that supports higher data change rates.
Question 59
A company migrates an on-premises Windows virtual machine (VM) to Azure. An administrator enables backups for the VM by using the Azure portal. The company reports that the Azure VM backup job is failing.
You need to troubleshoot the issue.
What should you do?
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
Question 60
A company enables just-in-time (JIT) virtual machine (VM) access in Azure.
An administrator observes a list of VMs on the Unsupported tab of the JIT VM access page in the Microsoft Defender for Cloud portal. You need to determine why some VMs are not supported for JIT VM access.
What should you conclude?
The Unsupported tab on the Just-in-Time VM access page in the Microsoft Defender for Cloud portal indicates that the VMs were provisioned by using a classic deployment Classic deployments were used in Azure before the deployment model was updated to Azure Resource Manager, which is now the preferred model for deploying and managing resources in Azure.
