Correct: Connected mode requires internet connectivity and uses cloud control plane; Disconnected mode operates independently

Explanation:

  • Connected Mode: Requires ongoing internet connectivity to Azure, uses Azure portal for management, provides hybrid services
  • Disconnected Mode: No internet required, uses local control plane (Windows Admin Center), operates independently

The key difference is the dependency on Azure connectivity and where the control plane resides (cloud vs. local).

Review: Operating Modes Comparison


Answer 6: D

Correct: Azure Local Disconnected Mode

Explanation: For completely air-gapped environments (no internet connectivity), Azure Local Disconnected Mode is the only option that:

  • ✅ Operates without any internet connectivity
  • ✅ Uses local control plane (no cloud dependencies)
  • ✅ Provides Azure-consistent services on-premises
  • ✅ Supports completely isolated operations

Azure Government still requires internet connectivity. Connected Mode by definition needs connectivity. Sovereign Public Cloud requires cloud connection.

  • ✅ Operated by Microsoft (not a third-party partner)
  • ✅ Physically separate data centers from commercial Azure
  • ✅ Logically isolated network infrastructure
  • ✅ Has MORE compliance certifications than commercial (FedRAMP High, DoD IL6)
  • ✅ Available only to US government entities and partners (not worldwide)

Review: Azure Government Overview


Answer 8: B

Correct: To meet Chinese regulatory requirements for local cloud operators

Explanation: China’s Cybersecurity Law requires that cloud services in China be operated by Chinese companies with local data storage. 21Vianet is a licensed Chinese telecommunications provider that operates Azure China to comply with these regulations. Microsoft provides the technology and support to 21Vianet, but 21Vianet handles operations, billing, and customer support.

Review: Azure China (21Vianet)


Answer 9: C

Correct: Data in use (during processing)

Explanation: Azure Confidential Computing protects data while it’s being processed using hardware-based Trusted Execution Environments (TEEs). This completes the encryption story:

  • Data at Rest: Azure Storage Encryption, Azure Disk Encryption
  • Data in Transit: TLS/SSL encryption
  • Data in Use: Confidential Computing (Intel SGX, AMD SEV-SNP)

This protects against cloud provider access, privileged admins, and hardware attacks.

Review: Confidential Computing


Answer 10: B

Correct: Sovereign Private Cloud (Azure Local)

Explanation: Infrastructure types by model:

  • Sovereign Public Cloud: Shared infrastructure with logical isolation
  • Sovereign Private Cloud (Azure Local): Dedicated, single-tenant physical infrastructure
  • National Partner Clouds: Shared infrastructure (partner-operated)

Only Sovereign Private Cloud provides dedicated physical hardware exclusively for one customer.

Review: Model Comparison Matrix


Answer 11: C

Correct: Azure Policy with deny effect for non-EU regions

Explanation: Azure Policy with a “deny” effect is the correct approach to prevent resource creation outside allowed regions. The policy evaluates resource creation requests and denies any that don’t match the specified EU regions.

Example policy:

{
  "if": {
    "not": {
      "field": "location",
      "in": ["westeurope", "northeurope", "francecentral"]
    }
  },
  "then": {
    "effect": "deny"
  }
}

Azure Firewall controls network traffic, NSGs control subnet traffic, and Customer Lockbox controls support access - none prevent resource creation in specific regions.

Review: Azure Policy for Compliance


Answer 12: B

Correct: Azure Government

Explanation: Azure Government is specifically designed for US government workloads and is the only Microsoft cloud with:

  • FedRAMP High authorization
  • DoD Impact Level 5 and 6 authorization
  • Physical and logical separation from commercial cloud
  • US persons-only support

Azure commercial cloud (global) has FedRAMP Moderate only. Azure China is for Chinese operations. Policy enforcement alone doesn’t provide FedRAMP authorization.

Review: Azure Government Compliance


Answer 13: C

Correct: An aerospace company with classified defense data requiring air-gap

Explanation: Azure Local Disconnected Mode is specifically designed for:

  • Air-gapped environments (no internet)

  • Retail with elastic needs: Sovereign Public Cloud (elasticity needed)
  • Startup mobile app: Sovereign Public Cloud or commercial cloud (need scalability)
  • Aerospace with classified data: Sovereign Private Cloud Disconnected (air-gap required)
  • SaaS provider: Sovereign Public Cloud (global reach and scalability)

Review: Use Cases - Defense Contractor


Answer 14: B

Correct: Azure Arc to manage hybrid resources from Azure control plane

Explanation: Azure Arc provides unified management for hybrid and multi-cloud environments by:

  • Projecting on-premises and multi-cloud resources into Azure Resource Manager
  • Enabling Azure management tools (portal, CLI, ARM templates) for all resources
  • Applying Azure Policy across hybrid resources
  • Providing unified monitoring via Azure Monitor

This provides a single control plane for managing resources across cloud and on-premises, which is essential for hybrid sovereignty scenarios.

Review: Hybrid Architecture Scenarios


Answer 15: C

Correct: Steady-state workloads with consistent resource utilization

Explanation: Azure Local (Sovereign Private Cloud) TCO considerations:

When cost-effective:

  • ✅ Steady-state workloads (consistent utilization amortizes CapEx)
  • ✅ Long-term deployment (3-5 years to recover hardware investment)
  • ✅ Data gravity (large datasets, high I/O, expensive to move)
  • ✅ Latency requirements (can’t tolerate cloud latency)

When NOT cost-effective:

  • ❌ Variable/unpredictable workloads (cloud elasticity more economical)
  • ❌ Short-term projects (can’t amortize CapEx over short period)
  • ❌ Dev/test environments (cloud pay-as-you-go better)
