                                          質問 # 63
                                          Your data warehouse environment undergoes a major version upgrade, introducing changes in SQL syntax and supported functions. How would you handle the migration of dbt projects to ensure compatibility?

                                          正解：A

                                          解説：
                                          A: Branches facilitate staged testing and rollback, if necessary. B: Testing in lower environments uncovers potential issues before production deployment. C Macros can in some cases smooth over compatibility issues.


                                          質問 # 64
                                          "Sometimes columns that should have data are showing null values!" exclaims a colleague. What initial debugging steps would you suggest beyond examining the model logic itself?

                                          正解：B

                                          解説：
                                          Don't limit yourself to the single model in question! Data flows throughout the project, and changes elsewhere might have cascading effects.


                                          質問 # 65
                                          You're using dbt Cloud and want to tighten control over when production deployments can occur. What dbt Cloud feature, in conjunction with your CI/CD configuration, would allow you to enforce this?

                                          正解：C

                                          解説：
                                          B enables you to define specific times or conditions for production deployments. Others are less directly related to controlling the timing.


                                          質問 # 66
                                          Given this dbt_project.yml:
                                          name: "jaffle_shop"
                                          version: "1.0.0"
                                          config-version: 2
                                          profile: "snowflake"
                                          model-paths: ["models"]
                                          macro-paths: ["macros"]
                                          snapshot-paths: ["snapshots"]
                                          target-path: "target"
                                          clean-targets:
                                          - "logs"
                                          - "target"
                                          - "dbt_modules"
                                          - "dbt_packages"
                                          models:
                                          jaffle_shop:
                                          orders:
                                          materialized: table
                                          When executing a dbt run your models build as views instead of tables:
                                          19:36:14 Found 1 model, 0 tests, 0 snapshots, 0 analyses, 179 macros, 0 operations, 0 seed files, 0 sources, 0 exposures, 0 metrics
                                          19:36:16 Concurrency: 1 threads (target='default')
                                          19:36:17 Finished running 1 view model in 3.35s.
                                          19:36:17 Completed successfully
                                          19:36:17 Done. PASS=1 WARN=0 ERROR=0 SKIP=0 TOTAL=1
                                          Which could be a root cause of why the model was not materialized as a table?
                                          The target-path is incorrectly configured.

                                          正解：B

                                          解説：
                                          The behavior described-dbt running the orders model as a view despite being explicitly configured as a table
                                          -indicates that dbt is not correctly detecting or applying the model-level configuration during compilation.
                                          dbt relies heavily on the target-path directory to write compiled SQL, manifest files, and run artifacts. If the target-path is misconfigured, pointing to a location that dbt does not handle correctly or that overlaps with another folder used internally, dbt may fail to load the correct configuration from the merged project settings.
                                          When dbt cannot locate the compiled configuration for a model, it defaults to its standard materialization type, which is view. This explains why the logs show:
                                          "Finished running 1 view model"
                                          even though the dbt_project.yml clearly declares:
                                          materialized: table.
                                          Additionally, the logs indicate no warnings or parsing errors, meaning dbt ran successfully but with incorrect settings-another indicator of configuration metadata being overridden or misplaced due to an incorrect target- path.
                                          By resolving the target-path issue, dbt will successfully load the model configuration and materialize the orders model as a table as intended.


                                          質問 # 67
                                          you're working with a dbt project where a central model fct_orders is refactored. Several downstream models rely on this fact table. Which of the following is the MOST efficient way to determine which downstream models might be affected by this change?

                                          正解：E

                                          解説：
                                          While options B, D, and E can indirectly hint at broken models, they're not the most efficient methods. The dbt docs commands allow you to directly visualize and explore dependencies within your dbt project, making it the ideal choice for this scenario.
