dbt Labs dbt Analytics Engineering Certification Exam 認定 dbt-Analytics-Engineering 試験問題 (Q201-Q206):

質問 # 201
"The compiled SQL looks correct, but I'm still getting wrong results in my model!" What might you suggest to a colleague having this issue?

A. Review the logic in 'on-run-start' or 'on-run-end' hooks, as they could be modifying data-
B. Test the model in isolation using the dbt run -select flag to narrow down dependencies.
C. All of the above.
D. Examine the source tables for data quality issues like duplicates or missing values.

正解：C

解説：
Sometimes, even with correct SQL, the issue can lie in data itself, external interactions, or hidden dependency effects.

質問 # 202
You're collaborating with a third-party analytics vendor who requires access to a subset of processed data within your dbt project for integration into their platform. How might you approach this securely?

A. Set up a data sharing mechanism through your data warehouse, if it supports this functionality, enabling controlled access.
B. A combination of the above might be needed, depending on the vendor's integration capabilities-
C. Utilize a dbt package to export specific models to CSV or JSON format and provide those files to the vendor
D. Generate a dedicated readout schema in your data warehouse with appropriate grants for the vendor's user

正解：B

解説：
A: A separate schema isolates access and allows tailoring permissions. B: Data sharing features provide a secure and controlled channel. C: Offline extracts might be the only option for some vendors.

質問 # 203
Your team sometimes defines raw data sources directly in dbt models using .yml files within the models directory. When might this approach be problematic?

A. If the raw dataset is accessed via a non-standard data warehouse connector.
B. If the raw dataset's schema is subject to change.
C. If the raw dataset requires complex transformations.
D. If multiple models utilize the same raw dataset.

正解：D

解説：
Defining raw sources within models leads to duplication and potential maintenance issues when multiple models share that dependency. A separate sources.yml file is generally preferred for shared datasets.

質問 # 204
You've made several commits to your feature branch. Before merging into the main branch, you want to consolidate the changes into a single, clear commit. What Git technique would help achieve this?

A. Run git rebase main followed by git commit -amend.
B. Use git rebase -i (interactive rebase) to squash commits together.
C. Manually copy your files into a new branch, commit, and issue a pull request.
D. git cherry-pick specific commits from your branch and reapply them.

正解：B

解説：
Interactive rebasing (git rebase -i) provides fine-grained control to squash, edit, or rearrange commits, creating a cleaner commit history

質問 # 205
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.

A. No
B. Yes

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.
