The correct answers are A and C.

dbt clone is a command introduced to efficiently replicate existing relations (tables/views) from one schema/environment to another within the same warehouse without fully rebuilding them. It typically leverages warehouse-level “clone” functionality (e.g., Snowflake zero-copy clone). To know what to clone, dbt needs information about previously built models; this is stored in artifacts like manifest.json. Therefore, A is correct: it requires a reference to a previous manifest/state to know which models and locations to operate on.

C is also correct because cloning a production schema into a development schema enables you to test code changes while pointing downstream tools (like BI dashboards) at the cloned data. That way, BI or ML systems can exercise new dbt logic without impacting real production objects.

Option B describes state:modified / state comparison behavior, but dbt clone does create (or clone) objects, so B is false.

Option D is incorrect because clone works within a warehouse, not across different warehouses.

Option E is wrong: _v# suffixing is for model versioning, not cloning.

Thus, A and C correctly describe the behavior and purpose of dbt clone.

Modularity in dbt means breaking transformations into small, reusable steps that are easy to reason about, test, and reuse. In this DAG, two staging models (stg_detail_categories and stg_details) feed into two mart-level models (skills_with_details and lessons_with_details). If there is repeated logic in those two mart models—such as common joins, filters, or derived fields—that logic is a good candidate to be extracted into an intermediate model.

Option E follows dbt best practices: inspect the SQL of lessons_with_details and skills_with_details and identify shared logic to move into a new intermediate model (for example, int_details_with_categories). Both downstream models can then reference this intermediate model using ref(), centralizing logic and improving maintainability.

Options A and B push joins/unions into the staging layer, which should focus on clean, 1:1 representations of sources—not combining multiple sources. Option C collapses distinct staging models into one, reducing clarity and breaking the source-to-staging contract. Option D creates an overly wide, less reusable final table instead of focusing on shared reusable logic.

Therefore, the action that truly increases modularity is Option E: creating an intermediate model based on common SQL patterns.

When converting a model-specific SQL query into a generic test, dbt expects the test macro to accept the two standard arguments used across all generic tests: model and column_name. These arguments allow dbt to automatically pass the correct table and the correct column when the test is applied in YAML.

The argument model represents the actual relation (table/view) being tested. dbt compiles the reference itself—so instead of writing ref('stg_orders'), generic tests always use {{ model }} to represent the referenced relation.

The argument column_name represents the actual column being tested. In this case, the hard-coded column amount_usd becomes the dynamic argument {{ column_name }}, allowing you to apply the logic to any numeric or validated column across multiple models.

So the generic version of your SQL becomes:

select *

from {{ model }}

where {{ column_name }} < 0

The other options are incorrect:

source is not the standard argument for generic tests.

model_name is not automatically passed by dbt.

field is not a recognized standard test argument.

Thus, the two correct standard arguments are model and column_name.
