- Correct answer : A — The command-line `--var` value wins, because CLI flags take precedence over target overrides, environment variables, and top-level defaults. A . The Databricks CLI resolves variable values in a fixed priority order, and a command-line `--var` flag sits at the top of that order, overriding target-level overrides, `BUNDLE_VAR_` environment variables, and top-level defaults. B . Target-level overrides are lower priority than a command-line `--var` flag; they only take effect when no higher-priority source, such as a CLI flag or environment variable, supplies a value for that variable. C . Having multiple potential sources for the same variable is expected and handled through a defined precedence order rather than treated as a conflict, so the CLI does not raise a validation error in this situation. D . Bundle variables resolve to a single scalar or complex value per deployment; the CLI does not merge values from multiple sources into a list or apply one as a runtime fallback for the other.
