DP-750 Certification Practice Question #87

Question

You operate several Lakeflow Jobs on Azure Databricks. For each operational situation below, you must choose the correct action in the Lakeflow Jobs UI/API. The diagram shows each situation mapped to a dropdown of possible actions. ```mermaid flowchart TD subgraph Situations S1["A multi-task job failed on task 'transform'.
Upstream tasks succeeded. You fixed the
notebook and want to re-run only the failed
and dependent tasks, reusing successful results."] S2["A continuous job hit consecutive failures
and is now in exponential-backoff state.
You fixed the cause and want to reset the
retry period and immediately start a new run."] S3["You need to launch a one-off execution of
a scheduled job right now, outside its
normal trigger, with the current settings."] S4["A single-task job is hung consuming compute
and producing nothing useful. You must
terminate the in-flight run immediately."] end subgraph Actions A1["Repair run"] A2["Restart run"] A3["Run now"] A4["Cancel / Stop run"] end S1 -.dropdown.-> A1 S2 -.dropdown.-> A2 S3 -.dropdown.-> A3 S4 -.dropdown.-> A4 ``` For each situation (S1–S4), select the single correct action.

Accepted Answer

Repair run is purpose-built for multi-task recovery — it re-runs only the failed/dependent tasks and keeps the successful task outputs, which exactly matches S1. The Lakeflow docs state that for a continuous job in exponential-backoff you click **Restart run** to reset the retry period and start a new run (S2). Run now is the manual one-off trigger using current settings (S3). To immediately terminate an active, hung run you Cancel/Stop it (S4); Repair would not apply to a single-task job.
