                                          dbt Labs dbt Analytics Engineering Certification Exam Sample Questions (Q105-Q110):

                                          NEW QUESTION # 105
                                          dbt Model Snippet

                                          Answer: D

                                          Explanation:
                                          Filters on sources frequently cause missing rows in joins. Check your source definitions and any model- level filtering. While the others could be issues, start with the most common cause.


                                          NEW QUESTION # 106
                                          You introduce a custom macro into your project. This is a snippet of your dbt_project.yml:YAML

                                          Answer: C

                                          Explanation:
                                          Check your macro file paths, as an incorrect configuration would prevent dbt from finding the macro. The others are likely not the issue but worth double-checking.


                                          NEW QUESTION # 107
                                          dbt Model Snippet:SQL

                                          Answer: B

                                          Explanation:
                                          Focus on the calculation itself, as the rest of the structure seems expected. The source reference and grouping appear standard.


                                          NEW QUESTION # 108
                                          You are building an incremental model.
                                          Identify the circumstances in which is_incremental() would evaluate to True or False.

                                          Answer:

                                          Explanation:

                                          Explanation:
                                          1. There is a config block at the top of the model with materialized = 'table'
                                          ## Answer: False
                                          2. The corresponding table already exists in the data warehouse
                                          ## Answer: True
                                          3. The incremental model was executed with the --full-refresh flag
                                          ## Answer: False
                                          4. The corresponding table does not already exist in the data warehouse
                                          ## Answer: False
                                          The is_incremental() macro in dbt is used within an incremental model to determine whether the current invocation should perform an incremental update or a full rebuild. It evaluates to True only during an incremental run when the target table already exists in the data warehouse and dbt is not performing a full refresh.
                                          For is_incremental() to return True, two conditions must be met:
                                          * The model must be materialized as incremental, not table or view.Therefore, if the config specifies materialized = 'table', the model is not incremental, and the function evaluates to False.
                                          * The table already exists in the target schema.In this case, dbt will run the model in incremental mode, making is_incremental() return **True`.
                                          If the incremental model is run with --full-refresh, dbt intentionally rebuilds the entire table, meaning is_incremental() evaluates to False, even if the table exists.
                                          Lastly, if the target table does not exist yet, dbt must create it from scratch, so the run is treated as a full rebuild, not an incremental update, causing is_incremental() to evaluate to False.
                                          Thus, the only scenario where is_incremental() returns True is when the table exists and the model is actually incremental.


                                          NEW QUESTION # 109
                                          (Multiple Select)

                                          Answer: B,D

                                          Explanation:
                                          yml files allow for complex source schemas and column transformations. Access control and loading strategies are usually handled at the database or project-level configuration.
