Microsoft AZ-305 Practice Test 72
Question 710
An architecture proposal for event grid subscriptions and fanout relies on the following approach: Post the same financial credit every time a notification is received. Which specific failure or mismatch should the design reviewer identify?
- Tight coupling makes extending consumers difficult.
- One-attempt delivery risks lost downstream notifications.
- Subsequent manual edits can invalidate previously approved configuration.
- Duplicate delivery can double-process business changes.
Explanation
Correct Answer
D:Post the same financial credit every time a notification is received. Duplicate delivery can double-process business changes.
Incorrect Answers
A:That assessment refers to the separate proposal 'Have storage directly call one hardcoded function and assume unlimited independent subscribers.' not to the recommendation under review. Here, Duplicate delivery can double-process business changes.
B:That assessment refers to the separate proposal 'Drop every event immediately after one HTTP timeout.' not to the recommendation under review. Here, Duplicate delivery can double-process business changes.
C:This concern applies to Ignore drift because the last pipeline run was successful. in another design an application architecture design. The current proposal specifically fails because duplicate delivery can double-process business changes.
Question 711
Acceptance testing must establish the following operational result: One logical side effect proves idempotency. Which verification action most directly establishes that outcome?
- Return a controlled transient error and inspect retry and dead-letter behavior.
- Replay a known event and compare final business state.
- Create a blob and check both subscriptions received the event.
- Run a non-mutating plan and review proposed changes.
Explanation
Correct Answer
B:One logical side effect proves idempotency.
Incorrect Answers
A:That verification addresses the different requirement: A webhook event destination is unavailable briefly and should receive delivery retries. It does not directly establish one logical side effect proves idempotency.
C:That verification addresses the different requirement: An image ingestion service must invoke separate resizing and tagging handlers when a blob is created. It does not directly establish one logical side effect proves idempotency.
D:This is a test for A team has drift between the approved IaC definition and a running resource. The requirement here is instead demonstrated by replay a known event and compare final business state.
Question 712
Millions of clickstream events per minute must be read independently by analytics and fraud-detection teams. Which Azure architecture choice best meets this requirement?
- Route every unrelated device into one partition key indefinitely.
- Use Event Hubs partitions with separate consumer groups.
- Put all consumers on a single queue that removes each event after first read.
- Assume Event Hubs retains every published message forever with no retention configuration.
Explanation
Correct Answer
B:Append-only streams allow independent readers and replay within retention.
Incorrect Answers
A:A hot partition may limit useful parallelism. In the present requirement, millions of clickstream events per minute must be read independently by analytics and fraud-detection teams. The needed design instead works because append-only streams allow independent readers and replay within retention.
C:Competing queue consumers do not provide independent full-stream consumption. This proposal contradicts the stated architecture constraint.
D:Retention is bounded by service configuration. In the present requirement, millions of clickstream events per minute must be read independently by analytics and fraud-detection teams. The needed design instead works because append-only streams allow independent readers and replay within retention.
Question 713

- Retention is bounded by service configuration.
- Competing queue consumers do not provide independent full-stream consumption.
Explanation
Correct Answer
D:Put all consumers on a single queue that removes each event after first read. Competing queue consumers do not provide independent full-stream consumption.
Incorrect Answers
A:This concern applies to Replace every instance immediately without retaining an old release. in another design an application architecture design. The current proposal specifically fails because competing queue consumers do not provide independent full-stream consumption.
B:That assessment refers to the separate proposal 'Route every unrelated device into one partition key indefinitely.' not to the recommendation under review. Here, Competing queue consumers do not provide independent full-stream consumption.
C:That assessment refers to the separate proposal 'Assume Event Hubs retains every published message forever with no retention configuration.' not to the recommendation under review. Here, Competing queue consumers do not provide independent full-stream consumption.
Question 714
Acceptance testing must establish the following operational result: Both streams seeing the records proves independent readers. Which verification action most directly establishes that outcome?
- Replay from a known checkpoint within retention and verify event counts.
- Start two consumer groups from distinct checkpoints and compare events.
- Analyze partition-level input and processing lag under realistic load.
- Route a small test share to the new build and trigger a rollback.
Explanation
Correct Answer
B:Both streams seeing the records proves independent readers.
Incorrect Answers
A:That verification addresses the different requirement: A telemetry consumer needs to resume from yesterday after a bug fix. It does not directly establish both streams seeing the records proves independent readers.
C:That verification addresses the different requirement: An event source requires large throughput but one partition is consistently overloaded. It does not directly establish both streams seeing the records proves independent readers.
D:This is a test for A production app update must avoid user-visible disruption and support quick rollback. The requirement here is instead demonstrated by start two consumer groups from distinct checkpoints and compare events.
Question 715
A telemetry consumer needs to resume from yesterday after a bug fix. Which Azure architecture choice best meets this requirement?
- Assume Event Hubs retains every published message forever with no retention configuration.
- Route every unrelated device into one partition key indefinitely.
- Put all consumers on a single queue that removes each event after first read.
- Configure suitable Event Hubs retention and durable consumer checkpoints.
Explanation
Correct Answer
D:Offsets support replay while the event remains in the retention window.
Incorrect Answers
A:Retention is bounded by service configuration. This proposal contradicts the stated architecture constraint.
B:A hot partition may limit useful parallelism. In the present requirement, a telemetry consumer needs to resume from yesterday after a bug fix. The needed design instead works because offsets support replay while the event remains in the retention window.
C:Competing queue consumers do not provide independent full-stream consumption. In the present requirement, a telemetry consumer needs to resume from yesterday after a bug fix. The needed design instead works because offsets support replay while the event remains in the retention window.
Question 716
An architecture proposal for event hubs telemetry architecture relies on the following approach: Assume Event Hubs retains every published message forever with no retention configuration. Which specific failure or mismatch should the design reviewer identify?
- Competing queue consumers do not provide independent full-stream consumption.
- A hot partition may limit useful parallelism.
- Retention is bounded by service configuration.
- Key collision can leak or overwrite another tenant's state.
Explanation
Correct Answer
C:Assume Event Hubs retains every published message forever with no retention configuration. Retention is bounded by service configuration.
Incorrect Answers
A:That assessment refers to the separate proposal 'Put all consumers on a single queue that removes each event after first read.' not to the recommendation under review. Here, Retention is bounded by service configuration.
B:That assessment refers to the separate proposal 'Route every unrelated device into one partition key indefinitely.' not to the recommendation under review. Here, Retention is bounded by service configuration.
D:This concern applies to Let all application tenants write to one identical session key. in another design an application architecture design. The current proposal specifically fails because retention is bounded by service configuration.
Question 717

- Assume Event Hubs retains every published message forever with no retention configuration.
Explanation
Correct Answer
C:Partitioning determines how events and consumers share capacity.
Incorrect Answers
A:Competing queue consumers do not provide independent full-stream consumption. In the present requirement, an event source requires large throughput but one partition is consistently overloaded. The needed design instead works because partitioning determines how events and consumers share capacity.
B:A hot partition may limit useful parallelism. This proposal contradicts the stated architecture constraint.
