- A. The new Job fails because one with that name already exists
- B. Helm deletes it just before creating the new Job
- C. Helm keeps both and adds a revision suffix to the new one
- D. Helm deleted it right after it succeeded last time

**Answer:** Helm deletes it just before creating the new Job

**Explanation:** Hook resources aren't tracked as part of the release, so they stay in the cluster after they run. When no delete policy is set, Helm applies before-hook-creation, which removes the previous resource just before creating the new one. Use hook-succeeded or hook-failed to clean up right after the hook finishes.
