Databricks Certified Data Engineer Professional 認定 Databricks-Certified-Data-Engineer-Professional 試験問題:

1. The data architect has decided that once data has been ingested from external sources into the Databricks Lakehouse, table access controls will be leveraged to manage permissions for all production tables and views.
The following logic was executed to grant privileges for interactive queries on a production database to the core engineering group.
GRANT USAGE ON DATABASE prod TO eng;
GRANT SELECT ON DATABASE prod TO eng;
Assuming these are the only privileges that have been granted to the eng group and that these users are not workspace administrators, which statement describes their privileges?

A) Group members are able to query all tables and views in the prod database, but cannot create or edit anything in the database.
B) Group members are able to query and modify all tables and views in the prod database, but cannot create new tables or views.
C) Group members are able to create, query, and modify all tables and views in the prod database, but cannot define custom functions.
D) Group members have full permissions on the prod database and can also assign permissions to other users or groups.
E) Group members are able to list all tables in the prod database but are not able to see the results of any queries on those tables.

2. A faulty IoT sensor in a factory reports a temperature of -500, causing the LDP pipeline to fail the expectation, which only allows values between -100 and 200 degrees Celsius. The data engineer would like to further analyze the faulty data to better understand the reason behind this. How should the data engineer resolve the faulty data while ensuring data quality standards are maintained?

A) Ignore the error and simply re-run the pipeline, as Databricks will automatically skip the problematic record on the next run.
B) Fix the pipeline code and implement a quarantine logic to isolate the faulty data before re-running the pipeline.
C) Remove all expectations form the pipeline to prevent any future failures, regardless of data quality.
D) Change the expectation action from fail to warn so that invalid records are included in the output and the pipeline does not fail.

3. In order to prevent accidental commits to production data, a senior data engineer has instituted a policy that all development work will reference clones of Delta Lake tables. After testing both deep and shallow clone, development tables are created using shallow clone. A few weeks after initial table creation, the cloned versions of several tables implemented as Type 1 Slowly Changing Dimension (SCD) stop working. The transaction logs for the source tables show that vacuum was run the day before.
Why are the cloned tables no longer working?

A) The metadata created by the clone operation is referencing data files that were purged as invalid by the vacuum command
B) The data files compacted by vacuum are not tracked by the cloned metadata; running refresh on the cloned table will pull in recent changes.
C) Tables created with SHALLOW CLONE are automatically deleted after their default retention threshold of 7 days.
D) Running vacuum automatically invalidates any shallow clones of a table; deep clone should always be used when a cloned table will be repeatedly queried.
E) Because Type 1 changes overwrite existing records, Delta Lake cannot guarantee data consistency for cloned tables.

4. A data engineer is designing a system to process batch patient encounter data stored in an S3 bucket, creating a Delta table (patient_encounters) with columns encounter_id, patient_id, encounter_date, diagnosis_code, and treatment_cost. The table is queried frequently by patient_id and encounter_date, requiring fast performance. Fine-grained access controls must be enforced. The engineer wants to minimize maintenance and boost performance. How should the data engineer create the patient_encounters table?

A) Create a managed table in Unity Catalog. Configure Unity Catalog permissions for access controls, and rely on predictive optimization to enhance query performance and simplify maintenance.
B) Create a managed table in Unity Catalog. Configure Unity Catalog permissions for access controls, schedule jobs to run OPTIMIZE and VACUUM commands daily to achieve best performance.
C) Create a managed table in Hive Metastore. Configure Hive Metastore permissions for access controls, and rely on predictive optimization to enhance query performance and simplify maintenance.
D) Create an external table in Unity Catalog, specifying an S3 location for the data files. Enable predictive optimization through table properties, and configure Unity Catalog permissions for access controls.

5. An external object storage container has been mounted to the location /mnt/finance_eda_bucket.
The following logic was executed to create a database for the finance team:

After the database was successfully created and permissions configured, a member of the finance team runs the following code:

If all users on the finance team are members of the finance group, which statement describes how the tx_sales table will be created?

A) An external table will be created in the storage container mounted to /mnt/finance eda bucket.
B) A logical table will persist the query plan to the Hive Metastore in the Databricks control plane.
C) A managed table will be created in the DBFS root storage container.
D) A logical table will persist the physical plan to the Hive Metastore in the Databricks control plane.
E) An managed table will be created in the storage container mounted to /mnt/finance_eda_bucket.
