Question 870
An architect proposes this change: Deploy Azure File Sync with a registered server endpoint and cloud endpoint for progressive file access migration. The workload context is: A Windows file server should migrate users gradually to Azure Files while keeping a local cache during transition. Which evidence would most directly validate the change?
- Run a nonproduction test migration and validate application services before committing final cutover.
- Run a test transfer and compare file tree, permissions/metadata and incremental changes.
- Deploy a pilot on App Service and test application endpoints and dependent services.
- Sync a test folder and verify cloud share content and on-prem client access remain consistent.
Explanation
Correct Answer
D:The acceptance test is specific: Sync a test folder and verify cloud share content and on-prem client access remain consistent. Its purpose is to establish that the proposed architecture works: Deploy Azure File Sync with a registered server endpoint and cloud endpoint for progressive file access migration.
Incorrect Answers
A:That observation pertains to a separate failure: A one-time disk copy causes extended outage and incomplete changes after initial transfer. Its cause is: A continuous migration replication and controlled cutover process was not planned. It does not confirm the result of this design. The direct proof would be: Sync a test folder and verify cloud share content and on-prem client access remain consistent.
B:The alternative test targets: Use Azure Storage Mover or a suitable supported managed file migration workflow for the source and destination. The scenario's actual proposed remedy is: Deploy Azure File Sync with a registered server endpoint and cloud endpoint for progressive file access migration. Verify that one by: Sync a test folder and verify cloud share content and on-prem client access remain consistent.
C:This check validates a different workload: Deploy a pilot on App Service and test application endpoints and dependent services. Its associated design is: Use a supported App Service migration/readiness assessment and verify framework, authentication and dependency constraints. The required acceptance test here is: Sync a test folder and verify cloud share content and on-prem client access remain consistent.
Question 871
During architecture troubleshooting, a team reports: Moving the entire share at once disrupts users dependent on local UNC paths. Context: A Windows file server should migrate users gradually to Azure Files while keeping a local cache during transition. Which underlying design mistake explains the observed behavior most precisely?
- PaaS suitability and application dependencies were not assessed before migration.
- No staged file synchronization and local cache architecture was planned.
- A continuous migration replication and controlled cutover process was not planned.
- The chosen copy workflow does not preserve required file migration semantics.
Explanation
Correct Answer
B:The recorded behavior follows from: No staged file synchronization and local cache architecture was planned. The appropriate mitigation would be: Deploy Azure File Sync with a registered server endpoint and cloud endpoint for progressive file access migration. Verify with: Sync a test folder and verify cloud share content and on-prem client access remain consistent.
Incorrect Answers
A:The proposed diagnosis fits another scenario: PaaS suitability and application dependencies were not assessed before migration. It would typically be reflected by: The migrated site fails because an unsupported local COM component remains essential. The current evidence instead supports: No staged file synchronization and local cache architecture was planned.
C:This cause would explain a different symptom: A one-time disk copy causes extended outage and incomplete changes after initial transfer. The mechanism for that event is: A continuous migration replication and controlled cutover process was not planned. Here the stated symptom is: Moving the entire share at once disrupts users dependent on local UNC paths. Its cause is: No staged file synchronization and local cache architecture was planned.
D:The proposed diagnosis fits another scenario: The chosen copy workflow does not preserve required file migration semantics. It would typically be reflected by: A homegrown transfer misses file timestamps and directory layout on repeated retries. The current evidence instead supports: No staged file synchronization and local cache architecture was planned.
Question 872
The design change is: Deploy Azure File Sync with a registered server endpoint and cloud endpoint for progressive file access migration. The original failure was: Moving the entire share at once disrupts users dependent on local UNC paths. Which ongoing control best prevents recurrence of the same root cause?
- Monitor cloud tiering and synchronization errors during each cutover phase.
- Track unsupported framework dependencies and adapt them before production cutover.
- Rehearse test migration, cleanup and rollback after source VM changes.
- Run incremental delta verification before final user cutover.
Explanation
Correct Answer
A:This is an ongoing protection specific to the fault: Monitor cloud tiering and synchronization errors during each cutover phase. The recurrence risk is: No staged file synchronization and local cache architecture was planned. It should be checked using: Sync a test folder and verify cloud share content and on-prem client access remain consistent.
Incorrect Answers
B:The proposed control focuses on: PaaS suitability and application dependencies were not assessed before migration. For the design in the question, recurrence comes from: No staged file synchronization and local cache architecture was planned. A precise prevention step is: Monitor cloud tiering and synchronization errors during each cutover phase.
C:That safeguard manages another risk: A continuous migration replication and controlled cutover process was not planned. Its scenario is: A one-time disk copy causes extended outage and incomplete changes after initial transfer. The present recurring risk is: No staged file synchronization and local cache architecture was planned. The proper ongoing control is: Monitor cloud tiering and synchronization errors during each cutover phase.
D:This is a reasonable safeguard for a different fault: A homegrown transfer misses file timestamps and directory layout on repeated retries. That different mechanism is: The chosen copy workflow does not preserve required file migration semantics. The original incident here instead arises from: No staged file synchronization and local cache architecture was planned. The directly relevant safeguard is: Monitor cloud tiering and synchronization errors during each cutover phase.
Question 873
A design workshop has this requirement: A company has a classic IIS website with standard .NET runtime and wants to evaluate hosting on Azure App Service instead of rehosting Windows VMs. Operators currently observe: The migrated site fails because an unsupported local COM component remains essential. Select the ONE design remedy that best addresses the root cause.
- Use discovered application dependency maps to group cutover waves with tested inter-service connectivity and rollback.
- Use Azure Migrate database assessment and supported SQL assessment tools to identify blockers and target recommendations.
- Use a supported App Service migration/readiness assessment and verify framework, authentication and dependency constraints.
- Use Azure Migrate discovery and assessment with a suitable appliance and performance-based sizing.
Explanation
Correct Answer
C:The evidence (The migrated site fails because an unsupported local COM component remains essential.) identifies the following cause: PaaS suitability and application dependencies were not assessed before migration. The design that removes it is: Use a supported App Service migration/readiness assessment and verify framework, authentication and dependency constraints. The acceptance check is: Deploy a pilot on App Service and test application endpoints and dependent services.
Incorrect Answers
A:The option belongs to a different failure mechanism: Migration order ignored dependency connectivity and shared service placement. That situation exhibits: The first migrated app is unusable because its required database remains unreachable on-premises. For the stated case, the remedy is: Use a supported App Service migration/readiness assessment and verify framework, authentication and dependency constraints.
B:That design instead addresses another observed condition: Applications are moved to Azure SQL Database then break due to unassessed SQL Agent dependencies. Its technical cause is: Database service selection preceded discovery of instance-level feature requirements. The current workload exhibits: The migrated site fails because an unsupported local COM component remains essential. Its targeted remedy is: Use a supported App Service migration/readiness assessment and verify framework, authentication and dependency constraints.
D:The option belongs to a different failure mechanism: No structured server discovery and utilization assessment was completed. That situation exhibits: Migration planning uses manually guessed VM sizes and misses application dependencies. For the stated case, the remedy is: Use a supported App Service migration/readiness assessment and verify framework, authentication and dependency constraints.

Question 877
A solution architect is reviewing a workload: An organization is halfway through cloud migration and needs governance visibility of remaining on-prem servers without claiming they are running in Azure. The observed incident is: A migration dashboard excludes critical servers until their final Azure VM cutover. Which architecture choice most directly removes the identified weakness?
- Use Azure Arc-enabled Servers to inventory hybrid machines and apply supported policies/extensions.
- Use Azure Migrate assessment and business case cost estimates grounded in discovered utilization and licensing assumptions.
- Use the supported Azure Migrate server-migration workflow with replication, test migration and final cutover.
- Use Azure Migrate discovery and assessment with a suitable appliance and performance-based sizing.
Explanation
Correct Answer
A:This option addresses the actual design defect: The hybrid governance model incorrectly limits inventory to cloud-native servers. The correction is: Use Azure Arc-enabled Servers to inventory hybrid machines and apply supported policies/extensions. Confirm the outcome with: Register one on-prem machine and confirm inventory/policy reports while it remains physically on-premises.
Incorrect Answers
B:This choice mitigates an alternative scenario, where: A migration proposal assumes every on-prem CPU must map to an equally large Azure VM. The underlying issue there is: The cost model ignores actual measured utilization and licensing optimization. Here the root issue is: The hybrid governance model incorrectly limits inventory to cloud-native servers. Choose the corresponding action: Use Azure Arc-enabled Servers to inventory hybrid machines and apply supported policies/extensions.
C:The option belongs to a different failure mechanism: A continuous migration replication and controlled cutover process was not planned.
