Device Settings
Azure’s device settings configuration revolves around Azure AD joined devices, Azure AD registered devices, and Hybrid Azure AD joined devices. Here’s an outline of each:
- Azure AD Joined Devices: Ideal for devices that are entirely cloud-based as it offers a mobile and secure environment.
- Azure AD Registered Devices: Perfect for bring-your-own device (BYOD) scenarios where a device is personally owned but requires occasional access to company resources.
- Hybrid Azure AD Joined Devices: Best used in organizations that have on-premise Active Directory and use Azure AD. Both identity locations are connected.
For effective management of devices within Azure, enterprises should correctly identify the nature of the device and link it accordingly.
Device Identity
Device Identity management in Azure is managed through Azure AD and Azure IoT Hub identity registry. Azure AD manages identities for users and groups, while Azure IoT Hub manages device identities.
Azure AD Device Identity
When a device is registered with Azure AD, it establishes an identity that is used to authenticate the device when a user signs in. Azure AD generates a unique identifier (Device ID) used to authenticate the device.
Azure IoT Hub Device Identity
Azure IoT (Internet of Things) Hub identities exist within the Identity Registry, where devices register and get authenticated before gaining the ability to connect to the IoT Hub. Once a device’s identity is registered, the IoT Hub stores its Device ID, security keys, and enables or disables its connection to the IoT Hub.
Managing Device Registration
Managing device registration is a critical security task. For Azure AD, when a device gets into the state of registered, it’s also getting into a managed state.
In Azure IoT Hub, devices need to be registered ahead of time in the device identity registry. For a device to register itself, it sends a registration message to the IoT Hub containing its Device ID and security key.
Securing Device Identity and Settings
To ensure that your devices are secured, Azure encourages:
- Limiting Device Administrator Privileges: Device administrators possess considerable permissions for an Azure device, and it’s essential to limit the number of device administrators and regularly review their activities.
- Rotating Security Keys: Rotating security keys reduce the risk of keys being discovered over time.
- Implementing Multi-Factor Authentication: Multi-factor authentication adds an extra layer of security by requiring a second form of identification.
To sum up, the management of device settings and device identity involves understanding Azure’s device configuration options and how Azure manages device identities. Understanding and implementing secure registration processes and taking steps to secure device identity and settings strengthens the security of Azure environments.
Remember, learning only from reliable documentation, gaining practical experience, and testing your knowledge with practice exams will give you the best opportunity to pass the AZ-104 Microsoft Azure Administrator exam.

Interview Questions
What is Azure AD (Active Directory) Device Identity?
Azure AD Device identity is a representation of a device owned by an organization, registered to the cloud. The device identity is used to manage devices and authenticate if these devices are both trusted and managed.
Where can you view and manage all the devices registered with Azure AD?
You can view and manage all the devices registered with Azure AD in the “Devices” section of the Azure AD in the Azure portal.
What are the default device settings for Azure AD?
The default device settings for Azure AD are:
“Users may join devices to Azure AD” is set to All
“Users may register their devices as Azure AD Joined” is set to None
“Additional local administrators on Azure AD Joined devices” is set to None.
What is the purpose of device settings in Azure AD?
The device settings in Azure AD determine who can join devices to Azure AD, whether devices can be Azure AD joined, and also designates additional local administrators on Azure AD joined devices.
What are managed and unmanaged devices in Azure?
Managed devices are those enrolled in Intune or joined to on-premises AD domain or Azure AD. Unmanaged devices are those not managed by an organization, typically personal devices like home computers, smartphones etc.
What authentication methods are available for Azure AD devices?
The authentication methods for Azure AD devices include password hash synchronization, pass-through authentication, Federated authentication, and Smart card/ Windows Hello for Business.
What is the process to deregister a device from Azure AD?
To deregister a device from Azure AD, you must first sign in as a global administrator or device administrator. You can then access the ‘Devices’ page in the Azure portal, choose the device to be removed, and select ‘Delete’.
How can you enable Automatic MDM enrollment for devices?
Automatic MDM enrollment can be enabled in the ‘Mobility (MDM and MAM)’ section in Azure Active Directory in the Azure portal.
What is the user impact after a device is deleted from Azure AD?
Once a device is deleted from Azure AD, users cannot access company resources from that device using Azure AD until the device is re-registered or joined to Azure AD again.
What is the purpose of ‘Conditional Access’ in Azure AD?
Conditional Access in Azure AD is a tool used to provide security to your data. It allows administrators to implement automated access control decisions for accessing your cloud apps based on conditions.
What is the benefit of enabling the ‘Require MFA for admins’ in Azure AD?
The ‘Require MFA for admins’ setting gives an extra layer of security by requiring administrators to verify their identity using a second form of authentication.
Can you change the name of a device in Azure AD?
Yes, Azure AD allows you to change the device name.
In Azure, how can you limit the number of devices any one user can enroll?
In Azure, you can set a device enrollment limit by going to Intune > Device enrollment > Enrollment restrictions, and then editing the settings under ‘Device limit restrictions’.
How does Azure AD handle device identities?
Azure AD assigns a unique ID to each device when it is registered. This unique ID is then used for authentication, access control and configuration management purposes.
What is Azure Device Writeback?
Azure Device Writeback is a feature that allows devices registered in Azure AD to be written back to on-premises AD. It can be used in scenarios where on-premises resources need to know about the device identities.
