Question 660

Acceptance testing must establish the following operational result: Event-to-execution proof validates the integration. Which verification action most directly establishes that outcome?

  1. Submit long jobs and verify completion after client disconnects.
  2. Simulate loss of an instance group in one zone and inspect serving capacity.
  3. Measure cold-to-warm latency while testing private resource access.
  4. Publish a test event and confirm function execution with correlated telemetry.

Explanation

Correct Answer

D:

Event-to-execution proof validates the integration.

Incorrect Answers

A:

That verification addresses the different requirement: An HTTP-triggered function takes hours to process jobs and regularly times out on synchronous calls. It does not directly establish event-to-execution proof validates the integration.

B:

This is a test for An availability-critical VMSS must spread instances among multiple availability zones. The requirement here is instead demonstrated by publish a test event and confirm function execution with correlated telemetry.

C:

That verification addresses the different requirement: A payment function requires VNet access and predictable latency under bursty demand. It does not directly establish event-to-execution proof validates the integration.

Question 661

A payment function requires VNet access and predictable latency under bursty demand. Which Azure architecture choice best meets this requirement?

  1. Evaluate an eligible Functions hosting plan with private networking and prewarmed capacity.
  2. Increase an arbitrary HTTP timeout indefinitely with no durable state.
  3. Maintain a dedicated VM that polls storage every second despite low traffic.
  4. Assume all entry-level serverless plans have identical networking and no cold start behavior.

Explanation

Correct Answer

A:

Hosting plan choices trade cold starts, scaling and private connectivity support.

Incorrect Answers

B:

Client and platform timeouts still constrain synchronous reliability. In the present requirement, a payment function requires VNet access and predictable latency under bursty demand. The needed design instead works because hosting plan choices trade cold starts, scaling and private connectivity support.
