Microsoft AZ-305 Practice Test 62
Question 610
An application design relies on temporary local NVMe storage for critical persistent orders. Which Azure architecture choice best meets this requirement?
- Select the smallest burstable development VM based only on instance price.
- Provision a general-purpose CPU-only VM and expect CUDA support automatically.
- Move durable state to supported managed disks or managed data services.
- Store the only authoritative customer orders on ephemeral host-local disks.
Explanation
Correct Answer
C:Temporary VM-local storage may disappear when the VM is redeployed or moved.
Incorrect Answers
A:CPU credits and insufficient RAM can throttle a sustained memory-heavy application. In the present requirement, an application design relies on temporary local NVMe storage for critical persistent orders. The needed design instead works because temporary VM-local storage may disappear when the VM is redeployed or moved.
B:CPU-only instances lack the specified GPU hardware. In the present requirement, an application design relies on temporary local NVMe storage for critical persistent orders. The needed design instead works because temporary VM-local storage may disappear when the VM is redeployed or moved.
D:Ephemeral storage does not provide the required data durability guarantee. This proposal contradicts the stated architecture constraint.
Question 611
An architecture proposal for vm size and hardware constraints relies on the following approach: Store the only authoritative customer orders on ephemeral host-local disks. Which specific failure or mismatch should the design reviewer identify?
- CPU-only instances lack the specified GPU hardware.
- Ephemeral storage does not provide the required data durability guarantee.
- Eviction risks violate the steady mission-critical capacity requirement.
- CPU credits and insufficient RAM can throttle a sustained memory-heavy application.
Explanation
Correct Answer
B:Store the only authoritative customer orders on ephemeral host-local disks. Ephemeral storage does not provide the required data durability guarantee.
Incorrect Answers
A:That assessment refers to the separate proposal 'Provision a general-purpose CPU-only VM and expect CUDA support automatically.' not to the recommendation under review. Here, Ephemeral storage does not provide the required data durability guarantee.
C:This concern applies to Run the only production database on Spot with no eviction protection. in another design compute solutions design. The current proposal specifically fails because ephemeral storage does not provide the required data durability guarantee.
D:That assessment refers to the separate proposal 'Select the smallest burstable development VM based only on instance price.' not to the recommendation under review. Here, Ephemeral storage does not provide the required data durability guarantee.
Question 612
Acceptance testing must establish the following operational result: Durability testing exposes hidden local-disk dependencies. Which verification action most directly establishes that outcome?
- Recreate a nonproduction VM and validate order data persistence.
- Load-test memory pressure and CPU utilization on the candidate SKU.
- Model actual 24/7 consumption and pricing commitments.
- Run a representative GPU kernel and monitor accelerator utilization.
Explanation
Correct Answer
A:Durability testing exposes hidden local-disk dependencies.
Incorrect Answers
B:That verification addresses the different requirement: A trading app needs large RAM and fast local CPU while its data remains in a managed database. It does not directly establish durability testing exposes hidden local-disk dependencies.
C:This is a test for A production database needs stable always-on capacity for the next three years. The requirement here is instead demonstrated by recreate a nonproduction VM and validate order data persistence.
D:That verification addresses the different requirement: A specialized simulation requires GPU acceleration and a compatible driver stack. It does not directly establish durability testing exposes hidden local-disk dependencies.
Question 613
A stateless VM Scale Set must handle traffic spikes and recover from instance failure automatically. Which TWO components are appropriate? (Select TWO.)
- Configure health probes and replacement or repair of unhealthy instances.
- Store the only session copy on a disposable scale-in instance.
- Reboot every VM at once for each deployment.
- Configure autoscaling rules on workload-relevant metrics.
- Keep a single VM regardless of peak load.
Explanation
Correct Answers
A:Unhealthy instances must not remain the only serving capacity.
D:Autoscale changes instance counts to handle demand.
Incorrect Answers
B:Scale-in can delete a VM holding the only copy of active session state.
C:Simultaneous replacement creates avoidable downtime.
E:One VM does not provide automatic scale-out.
Question 614
An architecture proposal for vm scale set design and elasticity relies on the following approach: Keep one permanently running VM and hope CPU utilization controls traffic. Which specific failure or mismatch should the design reviewer identify?
- A single instance cannot provide the required elastic capacity or fault tolerance.
- One-off container primitives do not provide a full application rollout controller.
- A zonal outage could remove the whole fleet.
- Concurrent reboots can cause complete service outage.
Explanation
Correct Answer
A:Keep one permanently running VM and hope CPU utilization controls traffic. A single instance cannot provide the required elastic capacity or fault tolerance.
Incorrect Answers
B:This concern applies to Manually recreate every ACI instance for each release. in another design compute solutions design. The current proposal specifically fails because a single instance cannot provide the required elastic capacity or fault tolerance.
C:That assessment refers to the separate proposal 'Put every scale set instance in one zone and claim regional zone resilience.' not to the recommendation under review. Here, A single instance cannot provide the required elastic capacity or fault tolerance.
D:That assessment refers to the separate proposal 'Update all instances immediately with no minimum healthy threshold.' not to the recommendation under review. Here, A single instance cannot provide the required elastic capacity or fault tolerance.
Question 615
Acceptance testing must establish the following operational result: Elastic capacity response proves the autoscale policy is effective. Which verification action most directly establishes that outcome?
- Drive load above threshold and inspect scale-out and scale-in actions.
- Simulate loss of an instance group in one zone and inspect serving capacity.
- Demonstrate rolling updates and automatic service replacement on the target platform.
- Rehearse one rolling upgrade and record minimum available instances.
Explanation
Correct Answer
A:Elastic capacity response proves the autoscale policy is effective.
Incorrect Answers
B:That verification addresses the different requirement: An availability-critical VMSS must spread instances among multiple availability zones. It does not directly establish elastic capacity response proves the autoscale policy is effective.
C:This is a test for A company wants stable autoscaling, rolling deployments and service discovery across hundreds of container instances. The requirement here is instead demonstrated by drive load above threshold and inspect scale-out and scale-in actions.
D:That verification addresses the different requirement: A rolling OS image upgrade repeatedly removes all application instances simultaneously. It does not directly establish elastic capacity response proves the autoscale policy is effective.
Question 616
An availability-critical VMSS must spread instances among multiple availability zones. Which Azure architecture choice best meets this requirement?
- Configure zonal VMSS placement and a compatible health-based load-balancing layer.
- Update all instances immediately with no minimum healthy threshold.
- Keep one permanently running VM and hope CPU utilization controls traffic.
- Put every scale set instance in one zone and claim regional zone resilience.
Explanation
Correct Answer
A:Zone distribution prevents one zone from hosting all serving instances.
Incorrect Answers
B:Concurrent reboots can cause complete service outage. In the present requirement, an availability-critical VMSS must spread instances among multiple availability zones. The needed design instead works because zone distribution prevents one zone from hosting all serving instances.
