Question 490
At the Marble research institute during a controlled pilot, two clients load the same Dataverse row and a late save silently overwrites the first user's change. The project team must verify a scoped fix before rollout. Which technical explanation best accounts for the observed problem?
Explanation
Correct Answer
This is the cause indicated by the reported symptoms: unconditional last-writer-wins updates can lose a concurrent change. The corrective design is to use supported ETag and If-Match conditional requests for concurrency-sensitive updates, not to change unrelated components. In the Marble research institute, assess this against the documented optimistic concurrency etag scenario.
Incorrect Answers
This explanation corresponds to sensitive tool action approval rather than the symptoms in the case. The controlling cause here is that unconditional last-writer-wins updates can lose a concurrent change; the unrelated mechanism does not account for the observed behavior. For case R082-PL400-CASE-0123, the decisive context is the 1 deployment setting at the Marble research institute.
“Server-side Organization service calls must align with caller and privilege expectations” is not the controlling explanation for at the Marble research institute during a controlled pilot, two clients load the same Dataverse row and a late save silently overwrites the first user's change. The project team must verify a scoped fix before rollout. The cited causal relationship is unconditional last-writer-wins updates can lose a concurrent change. The matching answer is “Unconditional last-writer-wins updates can lose a concurrent change”.
“Independent HTTP operations can leave partial changes on a mid-sequence failure” is not the controlling explanation for at the Marble research institute during a controlled pilot, two clients load the same Dataverse row and a late save silently overwrites the first user's change. The project team must verify a scoped fix before rollout. The cited causal relationship is unconditional last-writer-wins updates can lose a concurrent change. The matching answer is “Unconditional last-writer-wins updates can lose a concurrent change”.
