Microsoft AZ-305 Practice Test 69

Question 680

A design review identifies: A stateless web API runs on identical Windows VMs and must automatically scale out when CPU remains above a target. The failure is: The API exhausts capacity because two manually provisioned VMs never scale. Select TWO distinct decisions that together provide the immediate technical solution AND an ongoing prevention control. A verification-only step does not replace either responsibility.

  1. Review autoscale threshold, scale-in rules and image version before peak seasons.
  2. Review VM image patching and guest configuration when changing OS versions.
  3. Choose Azure App Service with suitable plan and autoscale features for the supported web runtime.
  4. Select eligible GPU VM sizes or supported GPU-backed managed compute with compatible drivers and allocation quotas.
  5. Deploy Azure Virtual Machine Scale Sets with a suitable autoscale rule, image and load-balancing integration.

Explanation

Correct Answers

A:

This is an ongoing protection specific to the fault: Review autoscale threshold, scale-in rules and image version before peak seasons. The recurrence risk is: Capacity management lacks automated VM instance scaling and health integration. It should be checked using: Apply controlled CPU load and verify new scale-set instances join the healthy serving pool.

E:

The targeted implementation is: Deploy Azure Virtual Machine Scale Sets with a suitable autoscale rule, image and load-balancing integration. The problem is not generic resource availability: Capacity management lacks automated VM instance scaling and health integration. Verify the result by: Apply controlled CPU load and verify new scale-set instances join the healthy serving pool.

Incorrect Answers

B:

The proposed control focuses on: The chosen hosting abstraction does not expose the operating system features the app requires. For the design in the question, recurrence comes from: Capacity management lacks automated VM instance scaling and health integration. A precise prevention step is: Review autoscale threshold, scale-in rules and image version before peak seasons.

C:

That design instead addresses another observed condition: The team operates unnecessary webserver VMs and manually patches them for routine hosting. Its technical cause is: A full IaaS VM hosting model was retained though managed App Service meets the constraints. The current workload exhibits: The API exhausts capacity because two manually provisioned VMs never scale. Its targeted remedy is: Deploy Azure Virtual Machine Scale Sets with a suitable autoscale rule, image and load-balancing integration.

D:

This choice mitigates an alternative scenario, where: Inference falls below performance target on CPU-only VMs. The underlying issue there is: Compute selection does not meet model accelerator requirements. Here the root issue is: Capacity management lacks automated VM instance scaling and health integration. Choose the corresponding action: Deploy Azure Virtual Machine Scale Sets with a suitable autoscale rule, image and load-balancing integration.

Question 681

A design workshop has this requirement: A medical image processing VM tier must remain reachable when an Azure availability zone becomes unavailable. Operators currently observe: All medical analysis workers stop when their single zone fails. Select the ONE design remedy that best addresses the root cause.

  1. Deploy Azure Virtual Machine Scale Sets with a suitable autoscale rule, image and load-balancing integration.
  2. Evaluate Azure confidential VMs or supported confidential compute backed by hardware-based trusted execution appropriate to workload.
  3. Select eligible GPU VM sizes or supported GPU-backed managed compute with compatible drivers and allocation quotas.
  4. Place compatible VMs across supported zones with resilient load distribution and remove single-zone dependencies.

Explanation

Correct Answer

D:

The targeted implementation is: Place compatible VMs across supported zones with resilient load distribution and remove single-zone dependencies. The problem is not generic resource availability: VM placement lacks zone-level failure-domain diversity. Verify the result by: Simulate zonal unavailability and confirm remaining instances handle client requests.

Incorrect Answers

A:

The option belongs to a different failure mechanism: Capacity management lacks automated VM instance scaling and health integration. That situation exhibits: The API exhausts capacity because two manually provisioned VMs never scale. For the stated case, the remedy is: Place compatible VMs across supported zones with resilient load distribution and remove single-zone dependencies.

B:

That design instead addresses another observed condition: Highly sensitive data are processed without the required isolation boundary for memory in use. Its technical cause is: Ordinary VM encryption at rest alone does not provide the required in-use protection. The current workload exhibits: All medical analysis workers stop when their single zone fails. Its targeted remedy is: Place compatible VMs across supported zones with resilient load distribution and remove single-zone dependencies.

C:

This choice mitigates an alternative scenario, where: Inference falls below performance target on CPU-only VMs. The underlying issue there is: Compute selection does not meet model accelerator requirements. Here the root issue is: VM placement lacks zone-level failure-domain diversity. Choose the corresponding action: Place compatible VMs across supported zones with resilient load distribution and remove single-zone dependencies.

Question 682

The planned architecture is: Place compatible VMs across supported zones with resilient load distribution and remove single-zone dependencies. Workload context: A medical image processing VM tier must remain reachable when an Azure availability zone becomes unavailable. Which acceptance test demonstrates that the required behavior works?

  1. Simulate zonal unavailability and confirm remaining instances handle client requests.
  2. Apply controlled CPU load and verify new scale-set instances join the healthy serving pool.
  3. Benchmark inference throughput and verify GPU device use and memory under load.
  4. Verify eligible confidential-computing capability and attestation expectations in a test workload.

Explanation

Correct Answer

A:

The decisive evidence is: Simulate zonal unavailability and confirm remaining instances handle client requests. This measures the mechanism of the planned change, not an unrelated Azure service: Place compatible VMs across supported zones with resilient load distribution and remove single-zone dependencies.

Incorrect Answers

B:

This check validates a different workload: Apply controlled CPU load and verify new scale-set instances join the healthy serving pool. Its associated design is: Deploy Azure Virtual Machine Scale Sets with a suitable autoscale rule, image and load-balancing integration. The required acceptance test here is: Simulate zonal unavailability and confirm remaining instances handle client requests.

C:

That observation pertains to a separate failure: Inference falls below performance target on CPU-only VMs. Its cause is: Compute selection does not meet model accelerator requirements. It does not confirm the result of this design. The direct proof would be: Simulate zonal unavailability and confirm remaining instances handle client requests.

D:

The alternative test targets: Evaluate Azure confidential VMs or supported confidential compute backed by hardware-based trusted execution appropriate to workload. The scenario's actual proposed remedy is: Place compatible VMs across supported zones with resilient load distribution and remove single-zone dependencies. Verify that one by: Simulate zonal unavailability and confirm remaining instances handle client requests.

Question 683

The customer states: A medical image processing VM tier must remain reachable when an Azure availability zone becomes unavailable. An incident reveals: All medical analysis workers stop when their single zone fails. What cause best accounts for this evidence?

  1. Capacity management lacks automated VM instance scaling and health integration.
  2. Ordinary VM encryption at rest alone does not provide the required in-use protection.
  3. VM placement lacks zone-level failure-domain diversity.
  4. Compute selection does not meet model accelerator requirements.

Explanation

Correct Answer

C:

This is the failure mechanism rather than an incidental symptom: VM placement lacks zone-level failure-domain diversity. It accounts for: All medical analysis workers stop when their single zone fails. The architectural repair is: Place compatible VMs across supported zones with resilient load distribution and remove single-zone dependencies.

Incorrect Answers

A:

The alternative weakness is: Capacity management lacks automated VM instance scaling and health integration. Its associated failure is: The API exhausts capacity because two manually provisioned VMs never scale. Neither explains the present observation: All medical analysis workers stop when their single zone fails. The direct cause here is: VM placement lacks zone-level failure-domain diversity.

B:

This cause would explain a different symptom: Highly sensitive data are processed without the required isolation boundary for memory in use. The mechanism for that event is: Ordinary VM encryption at rest alone does not provide the required in-use protection. Here the stated symptom is: All medical analysis workers stop when their single zone fails. Its cause is: VM placement lacks zone-level failure-domain diversity.

D:

The alternative weakness is: Compute selection does not meet model accelerator requirements. Its associated failure is: Inference falls below performance target on CPU-only VMs. Neither explains the present observation: All medical analysis workers stop when their single zone fails. The direct cause here is: VM placement lacks zone-level failure-domain diversity.

Question 684

Workload context: A medical image processing VM tier must remain reachable when an Azure availability zone becomes unavailable. The implemented remedy is: Place compatible VMs across supported zones with resilient load distribution and remove single-zone dependencies. Which ongoing practice most specifically prevents recurrence of this failure: All medical analysis workers stop when their single zone fails.?

  1. Track per-zone quota/capacity and test readiness of zones added after scale-out.
  2. Audit GPU driver compatibility and regional SKU quota during scaling.
  3. Track confidential compute SKU support and attestation policy after platform upgrades.
  4. Review autoscale threshold, scale-in rules and image version before peak seasons.

Explanation

Correct Answer

A:

The key follow-up control is: Track per-zone quota/capacity and test readiness of zones added after scale-out. It avoids recurrence of the scenario in which: All medical analysis workers stop when their single zone fails. It addresses: VM placement lacks zone-level failure-domain diversity.

Incorrect Answers

B:

That safeguard manages another risk: Compute selection does not meet model accelerator requirements. Its scenario is: Inference falls below performance target on CPU-only VMs. The present recurring risk is: VM placement lacks zone-level failure-domain diversity. The proper ongoing control is: Track per-zone quota/capacity and test readiness of zones added after scale-out.

C:

This is a reasonable safeguard for a different fault: Highly sensitive data are processed without the required isolation boundary for memory in use. That different mechanism is: Ordinary VM encryption at rest alone does not provide the required in-use protection. The original incident here instead arises from: VM placement lacks zone-level failure-domain diversity. The directly relevant safeguard is: Track per-zone quota/capacity and test readiness of zones added after scale-out.

D:

The proposed control focuses on: Capacity management lacks automated VM instance scaling and health integration. For the design in the question, recurrence comes from: VM placement lacks zone-level failure-domain diversity. A precise prevention step is: Track per-zone quota/capacity and test readiness of zones added after scale-out.

Question 685

A solution architect is reviewing a workload: A licensed application needs its dedicated physical Azure host placement for licensing and isolation obligations. The observed incident is: A shared VM host does not satisfy the vendor's dedicated-host licensing constraint. Which architecture choice most directly removes the identified weakness?

  1. Evaluate Azure confidential VMs or supported confidential compute backed by hardware-based trusted execution appropriate to workload.
  2. Evaluate Azure Dedicated Host with eligible VM families and documented licensing eligibility.
  3. Use an appropriate VM temporary/local scratch disk only for disposable files and store durable results on managed disks or services.
  4. Select Azure Virtual Machines with appropriate VM size, networking and disk configuration rather than a restricted PaaS host.

Explanation

Correct Answer

B:

The evidence (A shared VM host does not satisfy the vendor's dedicated-host licensing constraint.) identifies the following cause: The architecture does not provide the required customer-controlled physical-host tenancy. The design that removes it is: Evaluate Azure Dedicated Host with eligible VM families and documented licensing eligibility. The acceptance check is: Inspect assigned VM physical host placement and verify the licensed workload runs on the dedicated host.

Incorrect Answers

A:

That design instead addresses another observed condition: Highly sensitive data are processed without the required isolation boundary for memory in use. Its technical cause is: Ordinary VM encryption at rest alone does not provide the required in-use protection. The current workload exhibits: A shared VM host does not satisfy the vendor's dedicated-host licensing constraint. Its targeted remedy is: Evaluate Azure Dedicated Host with eligible VM families and documented licensing eligibility.

C:

The option belongs to a different failure mechanism: Critical state was stored on nonpersistent temporary local storage. That situation exhibits: The application loses business files after a VM host maintenance event. For the stated case, the remedy is: Evaluate Azure Dedicated Host with eligible VM families and documented licensing eligibility.

D:

That design instead addresses another observed condition: The app cannot install its required host driver on a managed web platform. Its technical cause is: The chosen hosting abstraction does not expose the operating system features the app requires. The current workload exhibits: A shared VM host does not satisfy the vendor's dedicated-host licensing constraint. Its targeted remedy is: Evaluate Azure Dedicated Host with eligible VM families and documented licensing eligibility.

Question 686

An architect proposes this change: Evaluate Azure Dedicated Host with eligible VM families and documented licensing eligibility. The workload context is: A licensed application needs its dedicated physical Azure host placement for licensing and isolation obligations. Which evidence would most directly validate the change?

  1. Verify eligible confidential-computing capability and attestation expectations in a test workload.
  2. Install the driver on a test VM and validate service startup and OS-level operations.
  3. Redeploy the worker and confirm business results remain while disposable scratch may disappear.
  4. Inspect assigned VM physical host placement and verify the licensed workload runs on the dedicated host.

Explanation

Correct Answer

D:

This observation directly verifies the intended design: Inspect assigned VM physical host placement and verify the licensed workload runs on the dedicated host. The architecture being tested is: Evaluate Azure Dedicated Host with eligible VM families and documented licensing eligibility. The original symptom was: A shared VM host does not satisfy the vendor's dedicated-host licensing constraint.

Incorrect Answers

Context: A licensed application needs its dedicated physical Azure host placement for licensing and isolation obligations. Which underlying design mistake explains the observed behavior most precisely?

  1. The architecture does not provide the required customer-controlled physical-host tenancy.
  2. The chosen hosting abstraction does not expose the operating system features the app requires.
  3. Ordinary VM encryption at rest alone does not provide the required in-use protection.
  4. Critical state was stored on nonpersistent temporary local storage.

Explanation

Correct Answer

A:

The incident is explained by: The architecture does not provide the required customer-controlled physical-host tenancy. The reported symptom is: A shared VM host does not satisfy the vendor's dedicated-host licensing constraint. The corresponding design fix is: Evaluate Azure Dedicated Host with eligible VM families and documented licensing eligibility.

Incorrect Answers

B:

The proposed diagnosis fits another scenario: The chosen hosting abstraction does not expose the operating system features the app requires. It would typically be reflected by: The app cannot install its required host driver on a managed web platform. The current evidence instead supports: The architecture does not provide the required customer-controlled physical-host tenancy.

C:

The alternative weakness is: Ordinary VM encryption at rest alone does not provide the required in-use protection. Its associated failure is: Highly sensitive data are processed without the required isolation boundary for memory in use. Neither explains the present observation: A shared VM host does not satisfy the vendor's dedicated-host licensing constraint. The direct cause here is: The architecture does not provide the required customer-controlled physical-host tenancy.

D:

This cause would explain a different symptom: The application loses business files after a VM host maintenance event.

Question 689

A design workshop has this requirement: A research rendering pipeline can tolerate interruption and restart individual tasks, with a strict low-cost compute budget. Operators currently observe: Rendering jobs stop permanently when discounted spot capacity is reclaimed. Select the ONE design remedy that best addresses the root cause.

  1. Use Azure Spot Virtual Machines with interruption-tolerant queues and checkpointing when suitable.
  2. Select Azure Virtual Machines with appropriate VM size, networking and disk configuration rather than a restricted PaaS host.
  3. Use Azure Batch with pools, job/task scheduling and autoscaling for parallel batch workloads.
  4. Use Azure VMware Solution if supported and economically justified for the required VMware operational model.

Explanation

Correct Answer

A:

The evidence (Rendering jobs stop permanently when discounted spot capacity is reclaimed.) identifies the following cause: The workload lacks eviction handling and assumes spot capacity is guaranteed. The design that removes it is: Use Azure Spot Virtual Machines with interruption-tolerant queues and checkpointing when suitable. The acceptance check is: Simulate task eviction and verify unfinished work retries or resumes without data corruption.

Incorrect Answers

B:

The option belongs to a different failure mechanism: The chosen hosting abstraction does not expose the operating system features the app requires. That situation exhibits: The app cannot install its required host driver on a managed web platform. For the stated case, the remedy is: Use Azure Spot Virtual Machines with interruption-tolerant queues and checkpointing when suitable.

C:

That design instead addresses another observed condition: A single VM serializes thousands of independent jobs and misses the daily SLA. Its technical cause is: The workload lacks managed parallel task scheduling and scalable compute pools. The current workload exhibits: Rendering jobs stop permanently when discounted spot capacity is reclaimed. Its targeted remedy is: Use Azure Spot Virtual Machines with interruption-tolerant queues and checkpointing when suitable.

D:

This choice mitigates an alternative scenario, where: The proposed migration requires redesigning all VMware operations that the owner must retain initially. The underlying issue there is: A replacement IaaS platform was chosen despite strict VMware compatibility requirements. Here the root issue is: The workload lacks eviction handling and assumes spot capacity is guaranteed. Choose the corresponding action: Use Azure Spot Virtual Machines with interruption-tolerant queues and checkpointing when suitable.

Question 690

D:

The acceptance test is specific: Simulate task eviction and verify unfinished work retries or resumes without data corruption. Its purpose is to establish that the proposed architecture works: Use Azure Spot Virtual Machines with interruption-tolerant queues and checkpointing when suitable.

Incorrect Answers

A:

That observation pertains to a separate failure: The proposed migration requires redesigning all VMware operations that the owner must retain initially. Its cause is: A replacement IaaS platform was chosen despite strict VMware compatibility requirements. It does not confirm the result of this design. The direct proof would be: Simulate task eviction and verify unfinished work retries or resumes without data corruption.

B:

The alternative test targets: Use Azure Batch with pools, job/task scheduling and autoscaling for parallel batch workloads. The scenario's actual proposed remedy is: Use Azure Spot Virtual Machines with interruption-tolerant queues and checkpointing when suitable. Verify that one by: Simulate task eviction and verify unfinished work retries or resumes without data corruption.

C:

This check validates a different workload: Install the driver on a test VM and validate service startup and OS-level operations. Its associated design is: Select Azure Virtual Machines with appropriate VM size, networking and disk configuration rather than a restricted PaaS host. The required acceptance test here is: Simulate task eviction and verify unfinished work retries or resumes without data corruption.
