AZ-500 Question #359: Real Exam Question with Answer & Explanation

Question

Case Study 3 - Fabrikam, Inc General Overview Fabrikam, Inc. is a consulting company that has a main office in Montreal and branch offices in Seattle and New York. Fabrikam has IT, human resources (HR), and finance departments. Existing Environment Network Environment Fabrikam has a Microsoft 365 subscription and an Azure subscription named subscription1. The network contains an on-premises Active Directory domain named Fabrikam.com. The domain contains two organizational units (OUs) named OU1 and OU2. Azure AD Connect cloud sync syncs only OU1. The Azure resources hierarchy is shown in the following exhibit. The Azure Active Directory (Azure AD) tenant contains the users shown in the following table. Azure AD contains the resources shown in the following table. Subscription1 Resources Subscription1 contains the virtual networks shown in the following table. Subscription1 contains the network security groups (NSGs) shown in the following table. Subscription1 contains the virtual machines shown in the following table. Subscription1 contains the Azure key vaults shown in the following table. Subscription1 contains a storage account named storage1 in the West US Azure region. Planned Changes and Requirements Planned Changes Fabrikam plans to implement the following changes: Create two application security groups as shown in the following table. Associate the network interface of VM1 to ASG1. Deploy SecPol1 by using Azure Security Center. Deploy a third-party app named App1. A version of App1 exists for all available operating systems. Create a resource group named RG2. Sync OU2 to Azure AD. Add User1 to Group1. Technical Requirements Fabrikam identifies the following technical requirements: The finance department users must reauthenticate after three hours when they access SharePoint Online. Storage1 must be encrypted by using customer-managed keys and automatic key rotation. From Sentinel1, you must ensure that the following notebooks can be launched: - Entity Explorer - Account - Entity Explorer - Windows Host - Guided Investigation Process Alerts VM1, VM2, and VM3 must be encrypted by using Azure Disk Encryption. Just in time (JIT) VM access for VM1, VM2, and VM3 must be enabled. App1 must use a secure connection string stored in KeyVault1. KeyVault1 traffic must NOT travel over the internet. You need to encrypt storage1 to meet the technical requirements. Which key vaults can you use?

Options

• AKeyVault2 and KeyVault3 only
• BKeyVault1 only
• CKeyVault1 and KeyVault3 only
• DKeyVault1, KeyVault2, and KeyVault3

Explanation

Explanation

Why B is Correct: Storage1 is located in the West US Azure region, and customer-managed key encryption requires that the Key Vault used must be in the same region as the storage account. Based on the case study table, only KeyVault1 resides in the West US region, making it the only eligible vault to encrypt Storage1.

Why the Distractors are Wrong:

• A (KeyVault2 and KeyVault3 only): Neither KeyVault2 nor KeyVault3 are in the West US region, so neither can be used alone or together to encrypt Storage1.
• C (KeyVault1 and KeyVault3 only): KeyVault3 is not in the West US region, so it cannot be paired or used for this purpose; only KeyVault1 qualifies.
• D (All three vaults): Including KeyVault2 and KeyVault3 is incorrect because region mismatch disqualifies them from being used for customer-managed key encryption of Storage1.

Memory Tip: Think "Same Region, Same Key Vault" - for customer-managed key encryption in Azure Storage, the Key Vault and the storage account must always reside in the same Azure region. If regions don't match, the option is automatically eliminated. This is a common exam trap!
