Microsoft AZ-305 Practice Test 90

Question 890

The planned architecture is: Build a ready Azure landing zone using management groups, subscriptions, governance policies, identity and network foundations. Workload context: A new application migration cannot start until the Azure destination has baseline identity, network, policy, monitoring and billing controls. Which acceptance test demonstrates that the required behavior works?

  1. Register one on-prem machine and confirm inventory/policy reports while it remains physically on-premises.
  2. Provision a trial workload and verify access, DNS, logging and compliance controls before migration.
  3. Cut over a low-risk cohort and verify dependent login, database and message flows before the next wave.
  4. Compare recommendation sizing and total cost model with sampled observed VM metrics and licensing.

Explanation

Correct Answer

B:

The acceptance test is specific: Provision a trial workload and verify access, DNS, logging and compliance controls before migration. Its purpose is to establish that the proposed architecture works: Build a ready Azure landing zone using management groups, subscriptions, governance policies, identity and network foundations.

Incorrect Answers

A:

This check validates a different workload: Register one on-prem machine and confirm inventory/policy reports while it remains physically on-premises. Its associated design is: Use Azure Arc-enabled Servers to inventory hybrid machines and apply supported policies/extensions. The required acceptance test here is: Provision a trial workload and verify access, DNS, logging and compliance controls before migration.

C:

The alternative test targets: Use discovered application dependency maps to group cutover waves with tested inter-service connectivity and rollback. The scenario's actual proposed remedy is: Build a ready Azure landing zone using management groups, subscriptions, governance policies, identity and network foundations. Verify that one by: Provision a trial workload and verify access, DNS, logging and compliance controls before migration.

D:

This check validates a different workload: Compare recommendation sizing and total cost model with sampled observed VM metrics and licensing. Its associated design is: Use Azure Migrate assessment and business case cost estimates grounded in discovered utilization and licensing assumptions. The required acceptance test here is: Provision a trial workload and verify access, DNS, logging and compliance controls before migration.

Question 891

The customer states: A new application migration cannot start until the Azure destination has baseline identity, network, policy, monitoring and billing controls. An incident reveals: Migrated apps deploy into ad hoc subscriptions lacking logging, identity and routing controls. What cause best accounts for this evidence?

  1. Migration order ignored dependency connectivity and shared service placement.
  2. The cost model ignores actual measured utilization and licensing optimization.
  3. The destination landing zone was not prepared for migration waves.
  4. The hybrid governance model incorrectly limits inventory to cloud-native servers.

Explanation

Correct Answer

C:

The recorded behavior follows from: The destination landing zone was not prepared for migration waves. The appropriate mitigation would be: Build a ready Azure landing zone using management groups, subscriptions, governance policies, identity and network foundations. Verify with: Provision a trial workload and verify access, DNS, logging and compliance controls before migration.

Incorrect Answers

A:

This cause would explain a different symptom: The first migrated app is unusable because its required database remains unreachable on-premises. The mechanism for that event is: Migration order ignored dependency connectivity and shared service placement. Here the stated symptom is: Migrated apps deploy into ad hoc subscriptions lacking logging, identity and routing controls. Its cause is: The destination landing zone was not prepared for migration waves.

B:

The proposed diagnosis fits another scenario: The cost model ignores actual measured utilization and licensing optimization. It would typically be reflected by: A migration proposal assumes every on-prem CPU must map to an equally large Azure VM. The current evidence instead supports: The destination landing zone was not prepared for migration waves.

D:

This cause would explain a different symptom: A migration dashboard excludes critical servers until their final Azure VM cutover. The mechanism for that event is: The hybrid governance model incorrectly limits inventory to cloud-native servers. Here the stated symptom is: Migrated apps deploy into ad hoc subscriptions lacking logging, identity and routing controls. Its cause is: The destination landing zone was not prepared for migration waves.

Question 892

Workload context: A new application migration cannot start until the Azure destination has baseline identity, network, policy, monitoring and billing controls. The implemented remedy is: Build a ready Azure landing zone using management groups, subscriptions, governance policies, identity and network foundations. Which ongoing practice most specifically prevents recurrence of this failure: Migrated apps deploy into ad hoc subscriptions lacking logging, identity and routing controls.?

  1. Validate landing-zone readiness gates for each new subscription.
  2. Refresh the cost model when rightsizing and workload commitments change.
  3. Maintain wave sequencing and connectivity tests as dependencies are uncovered.
  4. Maintain agent health and differentiate discovered, Arc-managed and migrated machine states.

Explanation

Correct Answer

A:

The preventive control is: Validate landing-zone readiness gates for each new subscription. It targets the earlier cause: The destination landing zone was not prepared for migration waves. Confirm ongoing effectiveness by: Provision a trial workload and verify access, DNS, logging and compliance controls before migration.

Incorrect Answers

B:

This is a reasonable safeguard for a different fault: A migration proposal assumes every on-prem CPU must map to an equally large Azure VM. That different mechanism is: The cost model ignores actual measured utilization and licensing optimization. The original incident here instead arises from: The destination landing zone was not prepared for migration waves. The directly relevant safeguard is: Validate landing-zone readiness gates for each new subscription.

C:

The proposed control focuses on: Migration order ignored dependency connectivity and shared service placement. For the design in the question, recurrence comes from: The destination landing zone was not prepared for migration waves. A precise prevention step is: Validate landing-zone readiness gates for each new subscription.

D:

That safeguard manages another risk: The hybrid governance model incorrectly limits inventory to cloud-native servers. Its scenario is: A migration dashboard excludes critical servers until their final Azure VM cutover. The present recurring risk is: The destination landing zone was not prepared for migration waves. The proper ongoing control is: Validate landing-zone readiness gates for each new subscription.

Question 893

A solution architect is reviewing a workload: A team must build a business case comparing Azure target costs with current underutilized datacenter hardware before obtaining migration approval. The observed incident is: A migration proposal assumes every on-prem CPU must map to an equally large Azure VM. Which architecture choice most directly removes the identified weakness?

  1. Use Azure Migrate assessment and business case cost estimates grounded in discovered utilization and licensing assumptions.
  2. Use Azure Migrate database assessment and supported SQL assessment tools to identify blockers and target recommendations.
  3. Use the supported Azure Migrate server-migration workflow with replication, test migration and final cutover.
  4. Use Azure Migrate discovery and assessment with a suitable appliance and performance-based sizing.

Explanation

Correct Answer

A:

The evidence (A migration proposal assumes every on-prem CPU must map to an equally large Azure VM.) identifies the following cause: The cost model ignores actual measured utilization and licensing optimization. The design that removes it is: Use Azure Migrate assessment and business case cost estimates grounded in discovered utilization and licensing assumptions. The acceptance check is: Compare recommendation sizing and total cost model with sampled observed VM metrics and licensing.

Incorrect Answers

B:

The option belongs to a different failure mechanism: Database service selection preceded discovery of instance-level feature requirements. That situation exhibits: Applications are moved to Azure SQL Database then break due to unassessed SQL Agent dependencies. For the stated case, the remedy is: Use Azure Migrate assessment and business case cost estimates grounded in discovered utilization and licensing assumptions.

C:

That design instead addresses another observed condition: A one-time disk copy causes extended outage and incomplete changes after initial transfer. Its technical cause is: A continuous migration replication and controlled cutover process was not planned. The current workload exhibits: A migration proposal assumes every on-prem CPU must map to an equally large Azure VM. Its targeted remedy is: Use Azure Migrate assessment and business case cost estimates grounded in discovered utilization and licensing assumptions.

D:

This choice mitigates an alternative scenario, where: Migration planning uses manually guessed VM sizes and misses application dependencies. The underlying issue there is: No structured server discovery and utilization assessment was completed. Here the root issue is: The cost model ignores actual measured utilization and licensing optimization. Choose the corresponding action: Use Azure Migrate assessment and business case cost estimates grounded in discovered utilization and licensing assumptions.

Question 894

An architect proposes this change: Use Azure Migrate assessment and business case cost estimates grounded in discovered utilization and licensing assumptions. The workload context is: A team must build a business case comparing Azure target costs with current underutilized datacenter hardware before obtaining migration approval. Which evidence would most directly validate the change?

  1. Compare discovered machines and dependency maps to known inventory, then review assessment sizing results.
  2. Compare recommendation sizing and total cost model with sampled observed VM metrics and licensing.
  3. Run a nonproduction test migration and validate application services before committing final cutover.
  4. Run assessment against a representative SQL Server and review compatibility findings before migration.

Explanation

Correct Answer

B:

The decisive evidence is: Compare recommendation sizing and total cost model with sampled observed VM metrics and licensing. This measures the mechanism of the planned change, not an unrelated Azure service: Use Azure Migrate assessment and business case cost estimates grounded in discovered utilization and licensing assumptions.

Incorrect Answers

A:

That observation pertains to a separate failure: Migration planning uses manually guessed VM sizes and misses application dependencies. Its cause is: No structured server discovery and utilization assessment was completed. It does not confirm the result of this design. The direct proof would be: Compare recommendation sizing and total cost model with sampled observed VM metrics and licensing.

C:

This check validates a different workload: Run a nonproduction test migration and validate application services before committing final cutover. Its associated design is: Use the supported Azure Migrate server-migration workflow with replication, test migration and final cutover. The required acceptance test here is: Compare recommendation sizing and total cost model with sampled observed VM metrics and licensing.

D:

Its cause is: Database service selection preceded discovery of instance-level feature requirements. It does not confirm the result of this design. The direct proof would be: Compare recommendation sizing and total cost model with sampled observed VM metrics and licensing.

Question 895

During architecture troubleshooting, a team reports: A migration proposal assumes every on-prem CPU must map to an equally large Azure VM. Context: A team must build a business case comparing Azure target costs with current underutilized datacenter hardware before obtaining migration approval. Which underlying design mistake explains the observed behavior most precisely?

  1. No structured server discovery and utilization assessment was completed.
  2. Database service selection preceded discovery of instance-level feature requirements.
  3. A continuous migration replication and controlled cutover process was not planned.
  4. The cost model ignores actual measured utilization and licensing optimization.

Explanation

Correct Answer

D:

This is the failure mechanism rather than an incidental symptom: The cost model ignores actual measured utilization and licensing optimization. It accounts for: A migration proposal assumes every on-prem CPU must map to an equally large Azure VM. The architectural repair is: Use Azure Migrate assessment and business case cost estimates grounded in discovered utilization and licensing assumptions.

Incorrect Answers

A:

The proposed diagnosis fits another scenario: No structured server discovery and utilization assessment was completed. It would typically be reflected by: Migration planning uses manually guessed VM sizes and misses application dependencies. The current evidence instead supports: The cost model ignores actual measured utilization and licensing optimization.

B:

The alternative weakness is: Database service selection preceded discovery of instance-level feature requirements. Its associated failure is: Applications are moved to Azure SQL Database then break due to unassessed SQL Agent dependencies. Neither explains the present observation: A migration proposal assumes every on-prem CPU must map to an equally large Azure VM. The direct cause here is: The cost model ignores actual measured utilization and licensing optimization.

C:

The mechanism for that event is: A continuous migration replication and controlled cutover process was not planned. Here the stated symptom is: A migration proposal assumes every on-prem CPU must map to an equally large Azure VM. Its cause is: The cost model ignores actual measured utilization and licensing optimization.

Question 896

The design change is: Use Azure Migrate assessment and business case cost estimates grounded in discovered utilization and licensing assumptions. The original failure was: A migration proposal assumes every on-prem CPU must map to an equally large Azure VM. Which ongoing control best prevents recurrence of the same root cause?

  1. Refresh discovery data and application grouping before every migration wave.
  2. Rehearse test migration, cleanup and rollback after source VM changes.
  3. Track assessment blockers and reassess when application versions change.
  4. Refresh the cost model when rightsizing and workload commitments change.

Explanation

Correct Answer

D:

This is an ongoing protection specific to the fault: Refresh the cost model when rightsizing and workload commitments change. The recurrence risk is: The cost model ignores actual measured utilization and licensing optimization. It should be checked using: Compare recommendation sizing and total cost model with sampled observed VM metrics and licensing.

Question 897

A design workshop has this requirement: A retailer has dozens of coupled applications and needs migration waves ordered by shared database, network and identity dependencies. Operators currently observe: The first migrated app is unusable because its required database remains unreachable on-premises. Select the ONE design remedy that best addresses the root cause.

  1. Build a ready Azure landing zone using management groups, subscriptions, governance policies, identity and network foundations.
  2. Use a supported App Service migration/readiness assessment and verify framework, authentication and dependency constraints.
  3. Use discovered application dependency maps to group cutover waves with tested inter-service connectivity and rollback.
  4. Establish pre-cutover synchronization, validation checkpoints, source write-freeze/rollback plan and recovery roles.

Explanation

Correct Answer

C:

The evidence (The first migrated app is unusable because its required database remains unreachable on-premises.) identifies the following cause: Migration order ignored dependency connectivity and shared service placement. The design that removes it is: Use discovered application dependency maps to group cutover waves with tested inter-service connectivity and rollback. The acceptance check is: Cut over a low-risk cohort and verify dependent login, database and message flows before the next wave.

Incorrect Answers

A:

The option belongs to a different failure mechanism: The destination landing zone was not prepared for migration waves. That situation exhibits: Migrated apps deploy into ad hoc subscriptions lacking logging, identity and routing controls. For the stated case, the remedy is: Use discovered application dependency maps to group cutover waves with tested inter-service connectivity and rollback.

B:

That design instead addresses another observed condition: The migrated site fails because an unsupported local COM component remains essential. Its technical cause is: PaaS suitability and application dependencies were not assessed before migration. The current workload exhibits: The first migrated app is unusable because its required database remains unreachable on-premises. Its targeted remedy is: Use discovered application dependency maps to group cutover waves with tested inter-service connectivity and rollback.

D:

The option belongs to a different failure mechanism: Rollback ownership and write-direction controls were not defined. That situation exhibits: Both old and new databases accept conflicting updates after a failed migration cutover. For the stated case, the remedy is: Use discovered application dependency maps to group cutover waves with tested inter-service connectivity and rollback.
