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

1. What describes a primary technical challenge in ensuring consistent PII masking across all nodes in large-scale, distributed Databricks batch and streaming pipelines?

A) Dynamic data masking is applied only at rest, so it does not affect query performance.
B) Native masking in Databricks automatically synchronizes with all downstream external Databricks systems.
C) PII masking is only required for direct identifiers.
D) Masking functions must be standardized and managed through Unity Catalog, with enforcement applied across all relevant datasets to avoid any data inconsistency.

2. A view is registered with the following code:

Both users and orders are Delta Lake tables.
Which statement describes the results of querying recent_orders?

A) All logic will execute when the view is defined and store the result of joining tables to the DBFS; this stored data will be returned when the view is queried.
B) Results will be computed and cached when the view is defined; these cached results will incrementally update as new records are inserted into source tables.
C) All logic will execute at query time and return the result of joining the valid versions of the source tables at the time the query began.
D) All logic will execute at query time and return the result of joining the valid versions of the source tables at the time the query finishes.

3. A nightly batch job is configured to ingest all data files from a cloud object storage container where records are stored in a nested directory structure YYYY/MM/DD. The data for each date represents all records that were processed by the source system on that date, noting that some records may be delayed as they await moderator approval. Each entry represents a user review of a product and has the following schema:
user_id STRING, review_id BIGINT, product_id BIGINT, review_timestamp TIMESTAMP, review_text STRING The ingestion job is configured to append all data for the previous date to a target table reviews_raw with an identical schema to the source system. The next step in the pipeline is a batch write to propagate all new records inserted into reviews_raw to a table where data is fully deduplicated, validated, and enriched.
Which solution minimizes the compute costs to propagate this batch of data?

A) Use Delta Lake version history to get the difference between the latest version of reviews_raw and one version prior, then write these records to the next table.
B) Filter all records in the reviews_raw table based on the review_timestamp; batch append those records produced in the last 48 hours.
C) Reprocess all records in reviews_raw and overwrite the next table in the pipeline.
D) Configure a Structured Streaming read against the reviews_raw table using the trigger once execution mode to process new records as a batch job.
E) Perform a batch read on the reviews_raw table and perform an insert-only merge using the natural composite key user_id, review_id, product_id, review_timestamp.

4. A table named user_ltv is being used to create a view that will be used by data analysts on various teams. Users in the workspace are configured into groups, which are used for setting up data access using ACLs.
The user_ltv table has the following schema:
email STRING, age INT, ltv INT
The following view definition is executed:

An analyst who is not a member of the auditing group executes the following query:
SELECT * FROM user_ltv_no_minors
Which statement describes the results returned by this query?

A) All records from all columns will be displayed with the values in user_ltv.
B) All columns will be displayed normally for those records that have an age greater than 18; records not meeting this condition will be omitted.
C) All age values less than 18 will be returned as null values all other columns will be returned with the values in user_ltv.
D) All columns will be displayed normally for those records that have an age greater than 17; records not meeting this condition will be omitted.
E) All values for the age column will be returned as null values, all other columns will be returned with the values in user_ltv.

5. A junior developer complains that the code in their notebook isn't producing the correct results in the development environment. A shared screenshot reveals that while they're using a notebook versioned with Databricks Repos, they're using a personal branch that contains old logic. The desired branch named dev-2.3.9 is not available from the branch selection dropdown.
Which approach will allow this developer to review the current logic for this notebook?

A) Merge all changes back to the main branch in the remote Git repository and clone the repo again
B) Use Repos to merge the current branch and the dev-2.3.9 branch, then make a pull request to sync with the remote repository
C) Use Repos to pull changes from the remote Git repository and select the dev-2.3.9 branch.
D) Use Repos to checkout the dev-2.3.9 branch and auto-resolve conflicts with the current branch
E) Use Repos to make a pull request use the Databricks REST API to update the current branch to dev-2.3.9
