Question 570

An organization wants near-real-time SQL change streams to downstream analytics consumers. Which acceptance check should accompany the remediation?

  1. Oversized queries are denied or paged while ordinary client requests meet latency goals.
  2. A replay of change tables reconstructs expected mutations including relevant old and new values.
  3. Logical reads and transferred bytes decrease while requested data stays correct.
  4. A sample update arrives downstream with correct ordering and latency within the service target.

Explanation

Correct Answer

D:

CES can stream database changes to consumers; availability and supported scenarios vary by platform. The observation “A sample update arrives downstream with correct ordering and latency within the service target” directly confirms the chosen action worked for this situation: An organization wants near-real-time SQL change streams to downstream analytics consumers.

Incorrect Answers

A:

GraphQL and REST query surfaces require limits to prevent accidental overfetch and resource exhaustion. This observation would not establish that the required result occurred for An organization wants near-real-time SQL change streams to downstream analytics consumers. The confirming test is: A sample update arrives downstream with correct ordering and latency within the service target.

B:

CDC records change data for replay, unlike simple change tracking versions.

Question 571

A Fabric integration needs to publish database change events with bounded latency and consumer tracking. Which implementation most directly satisfies the stated requirement?

  1. Use the supported Azure Functions SQL trigger binding with a controlled change source.
  2. Externalize secrets and environment values in a managed deployment and validate DAB config at each stage.
  3. Evaluate Change Event Streaming where the target environment supports it and confirm current feature status.
  4. Use supported column-level encryption with governed key access and explicit decryption rights.

Explanation

Correct Answer

C:

CES can stream database changes to consumers; availability and supported scenarios vary by platform. For the described situation—A Fabric integration needs to publish database change events with bounded latency and consumer tracking—the targeted fix is Evaluate Change Event Streaming where the target environment supports it and confirm current feature status.
