Microsoft AZ-305 Practice Test 64
Question 630
Acceptance testing must establish the following operational result: Rollback exercise verifies release safety. Which verification action most directly establishes that outcome?
- Demonstrate rolling updates and automatic service replacement on the target platform.
- Execute a staging warm-up and swap-back test.
- Stress one app and observe the other's response-time behavior.
- Test TLS binding, staged deployment and scale-out under load.
Explanation
Correct Answer
B:Rollback exercise verifies release safety.
Incorrect Answers
A: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 execute a staging warm-up and swap-back test.
C:That verification addresses the different requirement: Two App Service web apps must use independent CPU budgets and scale without interfering with each other. It does not directly establish rollback exercise verifies release safety.
D:That verification addresses the different requirement: A normal web API needs managed TLS, continuous deployment and easy instance scaling without VM administration. It does not directly establish rollback exercise verifies release safety.
Question 631
A microservice platform requires Kubernetes rollout controls, GPU inference capacity, and node maintenance resilience. Which THREE AKS design elements are appropriate? (Select THREE.)
- Configure multiple replicas with readiness probes and appropriate disruption policy.
- Rely on a one-off Container Instance as an AKS control plane.
- Use supported GPU node pools and workload scheduling constraints for inference pods.
- Deploy on Azure Kubernetes Service with governed node pools.
- Run every GPU workload on CPU-only nodes without compatibility checks.
- Use one pod replica for every critical component and claim it survives any node failure.
Explanation
Correct Answers
A:Replicas and readiness reduce downtime during node changes.
C:GPU workloads need compatible accelerators and placement.
D:AKS provides Kubernetes orchestration and node-pool management.
Incorrect Answers
B:Standalone containers are not a Kubernetes orchestrator.
E:CPU nodes do not supply GPU hardware.
F:A single replica can be unavailable during node disruption.
Question 632
An architecture proposal for aks container orchestration relies on the following approach: Choose a standalone container instance for every interdependent service and expect Kubernetes controllers. Which specific failure or mismatch should the design reviewer identify?
- A zonal outage could remove the whole fleet.
- Uncoordinated instances lack native Kubernetes scheduling and deployment control.
- A single pod cannot provide continuous service during all node faults.
- CPU nodes cannot meet hardware accelerator requirements.
Explanation
Correct Answer
B:Choose a standalone container instance for every interdependent service and expect Kubernetes controllers. Uncoordinated instances lack native Kubernetes scheduling and deployment control.
Incorrect Answers
A:This concern applies to Put every scale set instance in one zone and claim regional zone resilience. in another design compute solutions design. The current proposal specifically fails because uncoordinated instances lack native Kubernetes scheduling and deployment control.
C:That assessment refers to the separate proposal 'Define a one-replica deployment and assume it guarantees zero node-failure outage.' not to the recommendation under review. Here, Uncoordinated instances lack native Kubernetes scheduling and deployment control.
D:That assessment refers to the separate proposal 'Put every pod on one low-cost CPU node regardless of GPU needs.' not to the recommendation under review. Here, Uncoordinated instances lack native Kubernetes scheduling and deployment control.
Question 633
Acceptance testing must establish the following operational result: Orchestration success validates the required platform. Which verification action most directly establishes that outcome?
- Simulate loss of an instance group in one zone and inspect serving capacity.

- Drain a test node and measure request continuity.
Explanation
Correct Answer
C:Orchestration success validates the required platform.
Incorrect Answers
A:This is a test for An availability-critical VMSS must spread instances among multiple availability zones. The requirement here is instead demonstrated by deploy a sample pod rollout with service discovery and health probes.
B:That verification addresses the different requirement: GPU model inference pods must run separately from ordinary lightweight API pods. It does not directly establish orchestration success validates the required platform.
D:That verification addresses the different requirement: An AKS service loses traffic when one node fails despite several healthy nodes. It does not directly establish orchestration success validates the required platform.
Question 634
GPU model inference pods must run separately from ordinary lightweight API pods. Which Azure architecture choice best meets this requirement?
- Use appropriately labeled AKS node pools with scheduling constraints and GPU-capable nodes.
- Define a one-replica deployment and assume it guarantees zero node-failure outage.

- Put every pod on one low-cost CPU node regardless of GPU needs.
Explanation
Correct Answer
A:Node pool and affinity rules target workloads to suitable compute.
Incorrect Answers
B:A single pod cannot provide continuous service during all node faults. In the present requirement, gPU model inference pods must run separately from ordinary lightweight API pods. The needed design instead works because node pool and affinity rules target workloads to suitable compute.
C:Uncoordinated instances lack native Kubernetes scheduling and deployment control. In the present requirement, gPU model inference pods must run separately from ordinary lightweight API pods. The needed design instead works because node pool and affinity rules target workloads to suitable compute.
D:CPU nodes cannot meet hardware accelerator requirements. This proposal contradicts the stated architecture constraint.
Question 635
An architecture proposal for aks container orchestration relies on the following approach: Put every pod on one low-cost CPU node regardless of GPU needs. Which specific failure or mismatch should the design reviewer identify?
- One-off container primitives do not provide a full application rollout controller.

- Uncoordinated instances lack native Kubernetes scheduling and deployment control.
- CPU nodes cannot meet hardware accelerator requirements.
Explanation
Correct Answer
D:Put every pod on one low-cost CPU node regardless of GPU needs. CPU nodes cannot meet hardware accelerator requirements.
Incorrect Answers
A:This concern applies to Manually recreate every ACI instance for each release. in another design compute solutions design. The current proposal specifically fails because cPU nodes cannot meet hardware accelerator requirements.
B:That assessment refers to the separate proposal 'Define a one-replica deployment and assume it guarantees zero node-failure outage.' not to the recommendation under review. Here, CPU nodes cannot meet hardware accelerator requirements.
C:That assessment refers to the separate proposal 'Choose a standalone container instance for every interdependent service and expect Kubernetes controllers.' not to the recommendation under review. Here, CPU nodes cannot meet hardware accelerator requirements.
