The instructions must be added to Space1 because a Genie knowledge store is scoped to the individual Genie space, now called a Genie Agent. Adding synonyms and business-language instructions there teaches Space1 that “transaction,” “event,” “order,” and “invoice” refer to sales information in Sales1. The configuration affects only that Genie space, satisfying the requirement that other spaces remain unchanged. Adding instructions to Sales1 or Schema1 would modify shared Unity Catalog metadata and could affect other consumers of those objects. Notebook1 is unrelated to the semantic instructions used by Genie when converting natural-language questions into SQL. Genie knowledge stores contain space-specific definitions, synonyms, join relationships, SQL expressions, and prompt-matching guidance without changing the underlying Unity Catalog objects.

The correct answers are C and D. Together they deliver cost-efficient autoscaling:

D (Enable autoscaling) allows the cluster to grow when workloads increase and shrink when they ease off. This satisfies both scale-up and scale-down requirements without manual intervention.

C (Auto-termination after 30 minutes of inactivity) ensures the cluster stops entirely when no work is running, eliminating the cost of an idle cluster. This is the cheapest possible state.

Option A (disable Photon) reduces compute acceleration — that ' s a performance regression with no meaningful cost benefit for autoscaling. Option B (compute policy that lets users manage settings) adds governance overhead and doesn ' t address scaling behaviour. Option E (fixed number of workers) is the opposite of autoscaling — a static worker count that either over-provisions during quiet periods or under-provisions during peaks.

The correct answer is B — Repair the current job run.

Repair Run is designed for exactly this situation: a long-running job where most tasks succeeded but the final task failed due to a transient issue. Instead of restarting the entire eight-task job from the beginning — wasting hours of compute — Repair Run re-executes only the failed task and any dependents that were skipped as a result. All tasks that completed successfully are marked done and their outputs are reused.

Option A (update job parameters) changes configuration for future runs but doesn ' t re-execute the failed task in the current run. Option C (Restart Job1) re-runs every task from the start — precisely what the question says to avoid. Option D (disable and re-enable the schedule) creates a brand-new run on the next schedule trigger, again starting from the beginning rather than repairing the existing run.
