최신 Databricks Certification Databricks-Certified-Data-Engineer-Professional 무료샘플문제

1. A data architect has heard about lake's built-in versioning and time travel capabilities. For auditing purposes they have a requirement to maintain a full of all valid street addresses as they appear in the customers table.
The architect is interested in implementing a Type 1 table, overwriting existing records with new values and relying on Delta Lake time travel to support long-term auditing. A data engineer on the project feels that a Type 2 table will provide better performance and scalability. Which piece of information is critical to this decision?

A) Delta Lake time travel cannot be used to query previous versions of these tables because Type 1 changes modify data files in place.
B) Delta Lake only supports Type 0 tables; once records are inserted to a Delta Lake table, they cannot be modified.
C) Shallow clones can be combined with Type 1 tables to accelerate historic queries for long-term versioning.
D) Data corruption can occur if a query fails in a partially completed state because Type 2 tables requires setting multiple fields in a single update.
E) Delta Lake time travel does not scale well in cost or latency to provide a long-term versioning solution.

2. A Data Engineer is building a fraud detection pipeline that calls out to Open AI, via a Python library, and needs to include an access token when using the API. Which Databricks CLI command should the Data Engineer use to create the secret?

A) databricks tokens put-token SCOPE KEY; dbutils.tokens.get (SCOPE, KEY)
B) databricks secrets put-secret SCOPE KEY; dbutils.secrets.get (SCOPE, KEY)
C) databricks secrets put-secret KEY SCOPE; dbutils.secrets.get (KEY, SCOPE)
D) databricks tokens put-token KEY SCOPE; dbutils.secrets.get (KEY, SCOPE)

3. A Delta Lake table representing metadata about content posts from users has the following schema:
user_id LONG, post_text STRING, post_id STRING, longitude FLOAT,
latitude FLOAT, post_time TIMESTAMP, date DATE
This table is partitioned by the date column. A query is run with the following filter:
longitude < 20 & longitude > -20
Which statement describes how data will be filtered?

A) No file skipping will occur because the optimizer does not know the relationship between the partition column and the longitude.
B) Statistics in the Delta Log will be used to identify data files that might include records in the filtered range.
C) The Delta Engine will use row-level statistics in the transaction log to identify the flies that meet the filter criteria.
D) Statistics in the Delta Log will be used to identify partitions that might Include files in the filtered range.
E) The Delta Engine will scan the parquet file footers to identify each row that meets the filter criteria.

4. Which statement describes the default execution mode for Databricks Auto Loader?

A) Cloud vendor-specific queue storage and notification services are configured to track newly arriving files; the target table is materialized by directly querying all valid files in the source directory.
B) Webhook trigger Databricks job to run anytime new data arrives in a source directory; new data automatically merged into target tables using rules inferred from the data.
C) Cloud vendor-specific queue storage and notification services are configured to track newly arriving files; new files are incrementally and impotently into the target Delta Lake table.
D) New files are identified by listing the input directory; new files are incrementally and idempotently loaded into the target Delta Lake table.
E) New files are identified by listing the input directory; the target table is materialized by directory querying all valid files in the source directory.

5. A data engineer is designing a secure data sharing strategy for their organization. The company needs to share sensitive customer analytics data with two different partners. Partner A uses Databricks with Unity Catalog enabled, while Partner B uses Apache Spark on AWS without Databricks. How should the company implement secure data sharing for these scenarios?

A) Open sharing protocol (D2O) should be used for both partners because it provides better security than D2D sharing. The bearer token approach is always more secure than Unity Catalog's native authentication.
B) Both partners should use the same Delta Sharing approach since security requirements are identical. You should create bearer tokens for both partners and use the open sharing protocol (D2O) for maximum compatibility.
C) Databricks-to-Databricks sharing (D2D) can only be used within the same cloud provider, so you must use open sharing (D2O) for any cross-cloud scenarios. Unit Catalog governance is not available when sharing with external platforms.
D) For Partner A, implement Databricks-to-Databricks sharing (D2D) with Unit Catalog integration and no-token exchange system. For Partner B, use open sharing protocol (D2O) with either bearer tokens or OIDC federation for authentication, ensuring both approaches maintain robust security and governance.
