Microsoft AZ-305 Practice Test 45
Question 440
An architecture proposal for azure analytics platform selection relies on the following approach: Let every reporting user overwrite the raw landing files. Which specific failure or mismatch should the design reviewer identify?
- Shared root keys expand leakage and administration risk.
- Uncontrolled raw-layer modification destroys reproducibility and lineage.
- A small transactional SQL tier is not a general Spark analytics engine.
- Individually copied files create drift and stale metrics.
Explanation
Correct Answer
B:Let every reporting user overwrite the raw landing files. Uncontrolled raw-layer modification destroys reproducibility and lineage.
Incorrect Answers
A:This concern applies to Place an Event Hubs namespace root key in every analytics container image. in another design data integration design. The current proposal specifically fails because uncontrolled raw-layer modification destroys reproducibility and lineage.
C:That assessment refers to the separate proposal 'Use one Azure SQL Basic database to execute unlimited distributed Spark jobs.' not to the recommendation under review. Here, Uncontrolled raw-layer modification destroys reproducibility and lineage.
D:That assessment refers to the separate proposal 'Export data into separate local spreadsheets maintained by each analyst.' not to the recommendation under review. Here, Uncontrolled raw-layer modification destroys reproducibility and lineage.
Question 441
Acceptance testing must establish the following operational result: Repeatability verifies transformation boundaries and reproducible metrics. Which verification action most directly establishes that outcome?

Explanation
Correct Answer
C:Repeatability verifies transformation boundaries and reproducible metrics.
Incorrect Answers
A:This is a test for Sensitive event streams require consumer apps to authenticate without embedded shared access keys. The requirement here is instead demonstrated by re-run a pipeline from immutable raw input into curated output.
B:That verification addresses the different requirement: A company stores large data lake files and needs distributed SQL and Spark analytics. It does not directly establish repeatability verifies transformation boundaries and reproducible metrics.
D:That verification addresses the different requirement: Business reporting must ingest warehouse tables into reusable governed semantic models. It does not directly establish repeatability verifies transformation boundaries and reproducible metrics.
Question 442
A real-time dashboard must aggregate sensor anomalies continuously while raw events arrive. Which Azure architecture choice best meets this requirement?
- Retry continuously with no backoff or checkpoint and discard failed batches.

Explanation
Correct Answer
C:A streaming analytics processor can calculate windows without waiting for a daily batch.
Incorrect Answers
A:Unbounded retries amplify throttling and risk data loss. In the present requirement, a real-time dashboard must aggregate sensor anomalies continuously while raw events arrive. The needed design instead works because a streaming analytics processor can calculate windows without waiting for a daily batch.
B:Unnecessary full reloads increase cost and impact the source. In the present requirement, a real-time dashboard must aggregate sensor anomalies continuously while raw events arrive. The needed design instead works because a streaming analytics processor can calculate windows without waiting for a daily batch.
D:A periodic file refresh cannot provide continuous anomaly detection. This proposal contradicts the stated architecture constraint.

Question 444
Acceptance testing must establish the following operational result: A timely dashboard update verifies end-to-end streaming. Which verification action most directly establishes that outcome?

Explanation
Correct Answer
A:A timely dashboard update verifies end-to-end streaming.
Incorrect Answers
B:That verification addresses the different requirement: An integration pipeline must protect itself against transient API rate limits without losing data. It does not directly establish a timely dashboard update verifies end-to-end streaming.
C:That verification addresses the different requirement: A nightly warehouse load should process only records changed since the prior successful run. It does not directly establish a timely dashboard update verifies end-to-end streaming.
D:This is a test for A telemetry analytics application must reprocess events from a previous checkpoint. The requirement here is instead demonstrated by inject synthetic high-temperature events and inspect processing latency.
Question 445
A nightly warehouse load should process only records changed since the prior successful run. Which Azure architecture choice best meets this requirement?
- Use a reliable watermark or change-data-capture pattern with checkpoint state.

Explanation
Correct Answer
A:Incremental processing avoids full-table scans while preserving change order.
