Microsoft AZ-305 Practice Test 76
Question 750
Acceptance testing must establish the following operational result: Dynamic configuration proves centralized feature control. Which verification action most directly establishes that outcome?
- Test a setting refresh and verify sensitive values remain in the vault.
- Run contract tests against old and new API versions.
- Toggle a controlled flag and observe authorized app behavior.
- Disconnect configuration temporarily and observe the client fallback behavior.
Explanation
Correct Answer
C:Dynamic configuration proves centralized feature control.
Incorrect Answers
A:That verification addresses the different requirement: Services require shared configuration and sensitive passwords without storing credentials in plaintext settings. It does not directly establish dynamic configuration proves centralized feature control.
B:This is a test for A team must introduce a breaking API schema while keeping existing consumers supported. The requirement here is instead demonstrated by toggle a controlled flag and observe authorized app behavior.
D:That verification addresses the different requirement: One region's configuration endpoint fails, but critical applications must continue using last known valid settings. It does not directly establish dynamic configuration proves centralized feature control.
Question 751
Services require shared configuration and sensitive passwords without storing credentials in plaintext settings. Which Azure architecture choice best meets this requirement?
- Keep nonsecret settings in App Configuration and reference secrets from Key Vault.
- Rebuild all microservices every time a feature flag toggles.
- Paste database admin passwords into public feature flag values.
- Require every request to block permanently when one config lookup fails.
Explanation
Correct Answer
A:Separating configuration from secret storage supports least privilege and rotation.
Incorrect Answers
B:Recompilation adds unnecessary rollout burden for runtime configuration. In the present requirement, services require shared configuration and sensitive passwords without storing credentials in plaintext settings. The needed design instead works because separating configuration from secret storage supports least privilege and rotation.
C:Shared configuration visibility is not secret custody. This proposal contradicts the stated architecture constraint.
D:Hard coupling makes a configuration outage an app-wide outage. In the present requirement, services require shared configuration and sensitive passwords without storing credentials in plaintext settings. The needed design instead works because separating configuration from secret storage supports least privilege and rotation.
Question 752
An architecture proposal for app configuration and key vault references relies on the following approach: Paste database admin passwords into public feature flag values. Which specific failure or mismatch should the design reviewer identify?

A:This is a test for Millions of clickstream events per minute must be read independently by analytics and fraud-detection teams. The requirement here is instead demonstrated by test a setting refresh and verify sensitive values remain in the vault.
B:That verification addresses the different requirement: One region's configuration endpoint fails, but critical applications must continue using last known valid settings. It does not directly establish runtime retrieval and storage inspection prove separation.
D:That verification addresses the different requirement: Several microservices need centrally governed nonsecret feature flags with gradual rollout. It does not directly establish runtime retrieval and storage inspection prove separation.
Question 754
One region's configuration endpoint fails, but critical applications must continue using last known valid settings. Which Azure architecture choice best meets this requirement?
- Design supported local caching or resilience behavior for configuration retrieval.
- Rebuild all microservices every time a feature flag toggles.
- Paste database admin passwords into public feature flag values.
- Require every request to block permanently when one config lookup fails.
Explanation
Correct Answer
A:A runtime dependency on a remote configuration store needs transient-failure tolerance.
Incorrect Answers
B:Recompilation adds unnecessary rollout burden for runtime configuration. In the present requirement, one region's configuration endpoint fails, but critical applications must continue using last known valid settings. The needed design instead works because a runtime dependency on a remote configuration store needs transient-failure tolerance.
