Microsoft AZ-305 Practice Test 63
Question 620
An architecture proposal for vm scale set design and elasticity relies on the following approach: Update all instances immediately with no minimum healthy threshold. Which specific failure or mismatch should the design reviewer identify?
- Concurrent reboots can cause complete service outage.
- A zonal outage could remove the whole fleet.
- Resource contention can violate independent performance objectives.
- A single instance cannot provide the required elastic capacity or fault tolerance.
Explanation
Correct Answer
A:Update all instances immediately with no minimum healthy threshold. Concurrent reboots can cause complete service outage.
Incorrect Answers
B: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, Concurrent reboots can cause complete service outage.
C:This concern applies to Put every critical app into one undersized shared plan. in another design compute solutions design. The current proposal specifically fails because concurrent reboots can cause complete service outage.
D:That assessment refers to the separate proposal 'Keep one permanently running VM and hope CPU utilization controls traffic.' not to the recommendation under review. Here, Concurrent reboots can cause complete service outage.
Question 621
Acceptance testing must establish the following operational result: Capacity evidence validates upgrade safety. Which verification action most directly establishes that outcome?
- Simulate loss of an instance group in one zone and inspect serving capacity.
- Drive load above threshold and inspect scale-out and scale-in actions.
- Stress one app and observe the other's response-time behavior.
- Rehearse one rolling upgrade and record minimum available instances.
Explanation
Correct Answer
D:Capacity evidence validates upgrade safety.
Incorrect Answers
A:That verification addresses the different requirement: An availability-critical VMSS must spread instances among multiple availability zones. It does not directly establish capacity evidence validates upgrade safety.
B:That verification addresses the different requirement: A stateless API experiences fourfold demand spikes but must avoid provisioning peak VMs all day. It does not directly establish capacity evidence validates upgrade safety.
C:This is a test for Two App Service web apps must use independent CPU budgets and scale without interfering with each other. The requirement here is instead demonstrated by rehearse one rolling upgrade and record minimum available instances.
Question 622
An Azure App Service application needs staged rollout with quick rollback and independent capacity from a noisy neighboring application. Which TWO choices meet the requirements? (Select TWO.)
- Require a manually managed Windows VM without needing OS access.
- Host both critical apps in one overloaded shared plan regardless of contention.
- Use deployment slots and a controlled staging-to-production swap for supported plans.
- Overwrite only the production package with no previous version.
- Place the application in a separate appropriately sized App Service plan.
Explanation
Correct Answers
C:Slots enable validation and swap-back recovery.
E:Separate plans isolate compute and scaling resources.
Incorrect Answers
A:IaaS introduces unnecessary maintenance.
B:Common plan capacity can lead to noisy-neighbor degradation.
D:Direct replacement prevents a simple slot rollback.
Question 623
An architecture proposal for app service web hosting and plans relies on the following approach: Deploy a custom Windows VM only for IIS with no OS control requirement. Which specific failure or mismatch should the design reviewer identify?
- Direct replacement removes simple slot-based rollback protection.
- Resource contention can violate independent performance objectives.
- IaaS introduces unnecessary patching and configuration operations.
- Eviction risks violate the steady mission-critical capacity requirement.
Explanation
Correct Answer
C:Deploy a custom Windows VM only for IIS with no OS control requirement. IaaS introduces unnecessary patching and configuration operations.
Incorrect Answers
A:That assessment refers to the separate proposal 'Overwrite the only production deployment without any previous-version path.' not to the recommendation under review. Here, IaaS introduces unnecessary patching and configuration operations.
B:That assessment refers to the separate proposal 'Put every critical app into one undersized shared plan.' not to the recommendation under review. Here, IaaS introduces unnecessary patching and configuration operations.
D: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 iaaS introduces unnecessary patching and configuration operations.
Question 624
Acceptance testing must establish the following operational result: Combined tests verify the managed hosting model. Which verification action most directly establishes that outcome?
- Execute a staging warm-up and swap-back test.
- Model actual 24/7 consumption and pricing commitments.
- Test TLS binding, staged deployment and scale-out under load.
- Stress one app and observe the other's response-time behavior.
Explanation
Correct Answer
C:Combined tests verify the managed hosting model.
Incorrect Answers
A:That verification addresses the different requirement: A new release requires immediate rollback without rebuilding the old app version. It does not directly establish combined tests verify the managed hosting model.
B: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 test TLS binding, staged deployment and scale-out under load.
D: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 combined tests verify the managed hosting model.
Question 625
Two App Service web apps must use independent CPU budgets and scale without interfering with each other. Which Azure architecture choice best meets this requirement?
- Put every critical app into one undersized shared plan.
- Overwrite the only production deployment without any previous-version path.
- Place them on appropriately separated App Service plans where isolation is required.
- Deploy a custom Windows VM only for IIS with no OS control requirement.
Explanation
Correct Answer
C:Apps in a common plan can share compute capacity and scale characteristics.
Incorrect Answers
A:Resource contention can violate independent performance objectives. This proposal contradicts the stated architecture constraint.
B:Direct replacement removes simple slot-based rollback protection. In the present requirement, two App Service web apps must use independent CPU budgets and scale without interfering with each other. The needed design instead works because apps in a common plan can share compute capacity and scale characteristics.
D:IaaS introduces unnecessary patching and configuration operations. In the present requirement, two App Service web apps must use independent CPU budgets and scale without interfering with each other. The needed design instead works because apps in a common plan can share compute capacity and scale characteristics.

Explanation
Correct Answer
A:Load isolation proves plan separation is justified.
Incorrect Answers
B: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 load isolation proves plan separation is justified.
C:This is a test for An availability-critical VMSS must spread instances among multiple availability zones. The requirement here is instead demonstrated by stress one app and observe the other's response-time behavior.
D:That verification addresses the different requirement: A new release requires immediate rollback without rebuilding the old app version. It does not directly establish load isolation proves plan separation is justified.

Explanation
Correct Answer
B:Slots support staged validation and rollback of eligible App Service releases.
