Question Image

SQLServer1 uses Microsoft SQL Server authentication.

Sub1 has an Azure Web Application Firewall (WAF) named WAF1 that has the following types of rule sets:

  • Azure-managed Default Rule Set (DRS)

Sub1 has the following compliance standards assigned in Microsoft Defender for Cloud:

  • NIST SP 800-53 Rev. 4
  • Microsoft cloud security benchmark (MCSB)
  • System and Organization Controls (SOC) 2 Type 2

Existing Environment — Sub2 Resources

Sub2 contains a resource group named RG2.

Planned Changes and Requirements — Planned Changes

Fabrikam plans to implement the following changes:

  • Deploy the following key vaults to RG1:
    • AKV2 in the West Europe Azure region
    • AKV3 in the Central US Azure region
    • AKV4 in the East US Azure region
  • Deploy the following key vaults to RG2:
    • AKV5 in the East US region
  • Configure VM1 to read data from storage1.
  • Create function apps that have the following hosting plans:
    • Fa1: Flex Consumption hosting plan
    • Fa2: Consumption hosting plan
    • Fa3: Dedicated hosting plan
  • For WAF1, implement rate-limiting rules based on request location.
  • Enable the NIST SP 800-53 Rev. 5 compliance standard in Defender for Cloud.
  • Create a new storage account named storage2 that supports Azure Table storage.
  • Enforce multifactor authentication (MFA) when database administrators access SQLdb1.
  • Implement ExpressRoute circuits to the on-premises network as shown in the following table.

For RG1, create a new Privileged Identity Management (PIM) eligible role assignment that assigns the Contributor role to supported groups.

Planned Changes and Requirements — Technical Requirements

Fabrikam has the following technical requirements:

  • If VM1 is deleted, the permissions for VM1 must be removed automatically.
  • The AKS1 managed identity must only be able to pull images from Registry1.
  • The ID1 managed identity must be able to push images to and pull images from Registry1.
  • All data in the storage accounts must be encrypted by using Fabrikam-managed keys.
  • All outbound traffic from the function apps to the on-premises network must use ExpressRoute circuits.
  • ExpressRoute connectivity between the on-premises network and the Azure environment must be encrypted by using Layer 2 or Layer 3 encryption.

You need to implement the planned change for storage2. The solution must meet the technical requirements for storage encryption.

What should you do?

Explanation

Azure Table storage requires an account encryption key to support customer-managed keys for table data. Creating storage2 with an account encryption key permits a Fabrikam-managed key from Azure Key Vault or Managed HSM to encrypt the account’s services, including Table storage. Encryption scopes are limited to Blob storage, and purge protection or an Azure RBAC assignment does not configure Storage account encryption.
