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.

===============

For AKS1, assign the AcrPull role on Registry1. AcrPull provides the permissions required to download container images from an Azure Container Registry without granting permissions to push, modify, or delete images. Microsoft documents that when AKS is integrated with an Azure Container Registry, the appropriate pull-only role is assigned to the AKS identity used for image pulls. This satisfies the explicit requirement that AKS1 must only be able to pull images and follows least privilege. Microsoft Learn

For ID1, assign AcrPush. Microsoft defines AcrPush as the built-in Azure RBAC role for identities that require both push and pull permissions on a non-ABAC-enabled Azure Container Registry. It therefore allows ID1 to upload container images and retrieve existing images from Registry1 without granting broad resource-management capabilities such as Contributor or Owner. Microsoft Learn

Contributor and Owner would grant substantially more Azure management permissions than required. Reader does not provide container image pull/push data-plane permissions.

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.

Storage2 must be configured to use an account encryption key. The planned storage account must support Azure Table storage, while the technical requirement specifies that all storage data must be encrypted using Fabrikam-managed keys, meaning customer-managed keys (CMKs).

Azure Storage treats Table and Queue encryption differently from Blob Storage and Azure Files. Microsoft states that to encrypt Table Storage or Queue Storage with a customer-managed key, the storage account must be configured at creation time to use an encryption key scoped to the account rather than the default service-scoped key. After creation, this setting cannot be changed. Microsoft Learn

An encryption scope does not solve this requirement because encryption scopes apply to Blob Storage containers and individual blobs, not Azure Table data. Microsoft Learn

An Azure RBAC assignment may later be required so that the storage account ' s managed identity can access the customer-managed key in Key Vault, but it does not itself configure Table Storage to support account-level CMK encryption. Purge protection applies to Azure Key Vault rather than storage2.

Therefore, when storage2 is created, configure Table Storage to use the account encryption key.

===============

Add a custom WAF rule. The planned change requires WAF1 to implement rate limiting based on the geographic location of incoming requests. Azure Web Application Firewall supports this combination directly through custom rate-limit rules.

Microsoft documents that Application Gateway WAF rate-limit rules can group requests by GeoLocation, where requests are categorized based on the geographic location derived from the client IP address. The rule can then apply the configured rate threshold independently to traffic originating from each geographic location. Microsoft Learn Azure WAF custom rules also support the GeoMatch operator, which evaluates requests according to their country or region of origin. Microsoft Learn

This makes a single custom rule the most direct and administratively efficient implementation.

The Azure-managed Default Rule Set (DRS) provides predefined protections against common web application attacks, such as injection and protocol attacks; it is not where custom geographic rate limits are defined. Bot Manager 1.1 identifies and handles automated bot traffic but is not the appropriate mechanism for general location-based rate limiting. Azure Policy can enforce configuration standards across resources but does not itself process web requests or impose per-location request thresholds.

Therefore, configure a custom rate-limit rule with geographic matching/grouping.

===============

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.

The technical requirement states that all outbound traffic from the function apps to the on-premises network must use ExpressRoute circuits. To accomplish this, the Function App hosting plan must support outbound virtual network integration, because the application must send outbound traffic into an Azure virtual network from which routes learned through or directed toward the ExpressRoute gateway can reach the on-premises environment.

Fa1, which uses the Flex Consumption plan, supports virtual network integration. Microsoft documents that Flex Consumption provides outbound virtual network connectivity and can therefore reach resources accessible through the integrated virtual network. Microsoft Learn

Fa3, which uses a Dedicated App Service plan, also supports outbound virtual network integration. Microsoft further documents that VNet-integrated Functions can have outbound traffic affected by BGP routes learned from an ExpressRoute gateway, and route tables can direct traffic through that gateway. Microsoft Learn

Fa2, however, uses the legacy Consumption plan, which does not support outbound virtual network integration. Consequently, it cannot meet the requirement to route its outbound on-premises traffic through ExpressRoute using this architecture. Microsoft Learn

Therefore, only Fa1 and Fa3 support the required networking configuration.

Requirement

Setting

Assign Role1 to User1

Users and groups

Enable User2 to request access to App1

Self-service

Comprehensive and Detailed 150 to 250 words of Explanation From [Cloud and AI Security Engineer/Course Guide/topics]:

To assign the application-specific Role1 to User1, use Users and groups in the enterprise application. Microsoft documents that app-role assignments are made from Enterprise applications → App1 → Users and groups → Add user/group, where you select the user and then choose the specific application role to assign.

To allow User2 to request access to App1, configure Self-service. Microsoft Entra self-service application access allows users to discover an application in My Apps and submit an access request. On the Self-service page, you can enable Allow users to request access to this application, optionally require approval, specify approvers, and define the application role assigned after approval.

Other settings shown in the exhibit do not satisfy these requirements. Roles and administrators controls administrative roles over the enterprise application itself, not assignment of an app-specific role to an end user. Single sign-on, Provisioning, Conditional Access, and Permissions serve different authentication, lifecycle, access-control, or consent purposes.

Final selections:

Users and groups

Self-service
