The first step is to enable a system-assigned managed identity on VM1. The scenario requires VM1 to read data from storage1 and also specifies that when VM1 is deleted, the permissions associated with VM1 must effectively cease automatically.

A system-assigned managed identity has a one-to-one lifecycle relationship with the Azure resource to which it belongs. Microsoft explicitly states that when the associated resource is deleted, its system-assigned managed identity is automatically deleted from Microsoft Entra ID. In contrast, a user-assigned identity such as ID1 exists independently and remains after the VM is deleted. Microsoft Learn

After enabling the identity, the appropriate storage data-plane role—such as Storage Blob Data Reader when VM1 requires read access to blobs—can be granted to VM1 ' s managed identity at the required scope. Microsoft documents this exact pattern for a Windows VM accessing Azure Storage: enable its managed identity and assign Storage Blob Data Reader to that identity. Microsoft Learn

Federated credentials are unnecessary for a VM ' s native managed identity. Assigning ID1 would violate the lifecycle requirement because ID1 is user-assigned and survives VM1 deletion. A role assignment cannot be created for VM1 ' s system identity until that identity exists.

Therefore, first enable VM1 ' s system-assigned managed identity.

Choose Admin1 because the planned Defender for Cloud change is to enable the NIST SP 800-53 Rev. 5 regulatory compliance standard for Sub1. Defender for Cloud implements regulatory compliance standards through Azure Policy initiatives, and assigning a new standard requires permissions to create or manage policy assignments.

Microsoft states that assigning a regulatory compliance standard requires Owner or Policy Contributor permissions at the relevant scope. Microsoft Learn Admin1 has the Resource Policy Contributor Azure role on Sub1, which provides the policy-management permissions required to assign policy initiatives and therefore supports enabling the NIST standard without granting broader resource-management permissions.

Admin2 has User Access Administrator, which manages Azure RBAC assignments but does not provide the policy-management permissions required for this operation. Admin3 has Contributor, which can manage Azure resources but is restricted from performing certain Microsoft.Authorization operations, including policy assignment operations needed here. Admin4 is a Global Administrator in Microsoft Entra but has no Azure role assignment for Sub1; Microsoft Entra directory administration does not automatically provide subscription-level Defender for Cloud policy-management rights.

Because Admin1 already has the specific policy-management role required for the change, selecting Admin1 satisfies both the functional requirement and the principle of least privilege.

Encryption type

ExpressRoute circuits

Layer 2 encryption

ER3 and ER4 only

Layer 3 encryption

ER1, ER2, ER3, and ER4

For Layer 2 encryption, Azure ExpressRoute uses MACsec (Media Access Control Security). Microsoft states that MACsec is available for ExpressRoute Direct connections because customers have dedicated physical ports connecting their edge routers directly to Microsoft Enterprise Edge routers. Therefore, both ER3 (ExpressRoute Direct) and ER4 (ExpressRoute Metro Direct) can use MACsec. Provider-based ExpressRoute circuits such as ER1 and ER2 do not expose dedicated ExpressRoute Direct ports to the customer and therefore do not support this native Layer 2 MACsec capability. Microsoft Learn

For Layer 3 encryption, ExpressRoute can use IPsec over ExpressRoute private peering. Unlike MACsec, IPsec is an end-to-end network-layer encryption mechanism and is not dependent on ExpressRoute Direct physical ports. Microsoft states that IPsec over ExpressRoute works with any ExpressRoute circuit, allowing encrypted connectivity between the on-premises network and Azure over private peering.
