Question 32

The business intelligence team has a dashboard configured to track various summary metrics for retail stories. This includes total sales for the previous day alongside totals and averages for a variety of time periods. The fields required to populate this dashboard have the following schema:

For Demand forecasting, the Lakehouse contains a validated table of all itemized sales updated incrementally in near real-time. This table named products_per_order, includes the following fields:

Because reporting on long-term sales trends is less volatile, analysts using the new dashboard only require data to be refreshed once daily. Because the dashboard will be queried interactively by many users throughout a normal business day, it should return results quickly and reduce total compute associated with each materialization.

Which solution meets the expectations of the end users while controlling and limiting possible costs?

Options:

A.

Use the Delta Cache to persists the products_per_order table in memory to quickly the dashboard with each query.

B.

Populate the dashboard by configuring a nightly batch job to save the required to quickly update the dashboard with each query.

C.

Use Structure Streaming to configure a live dashboard against the products_per_order table within a Databricks notebook.

D.

Define a view against the products_per_order table and define the dashboard against this view.

Question 33

A small company based in the United States has recently contracted a consulting firm in India to implement several new data engineering pipelines to power artificial intelligence applications. All the company's data is stored in regional cloud storage in the United States.

The workspace administrator at the company is uncertain about where the Databricks workspace used by the contractors should be deployed.

Assuming that all data governance considerations are accounted for, which statement accurately informs this decision?

Options:

A.

Databricks runs HDFS on cloud volume storage; as such, cloud virtual machines must be deployed in the region where the data is stored.

B.

Databricks workspaces do not rely on any regional infrastructure; as such, the decision should be made based upon what is most convenient for the workspace administrator.

C.

Cross-region reads and writes can incur significant costs and latency; whenever possible, compute should be deployed in the same region the data is stored.

D.

Databricks leverages user workstations as the driver during interactive development; as such, users should always use a workspace deployed in a region they are physically near.

E.

Databricks notebooks send all executable code from the user's browser to virtual machines over the open internet; whenever possible, choosing a workspace region near the end users is the most secure.

Hey, I heard the good news. I passed the certification exam!
Jaxson Jul 13, 2025
Yes, I passed too! And I have to say, I couldn't have done it without Cramkey Dumps.
Esmae
I highly recommend Cramkey Dumps to anyone preparing for the certification exam.
Mollie Jul 20, 2025
Absolutely. They really make it easier to study and retain all the important information. I'm so glad I found Cramkey Dumps.
Pippa
I was so happy to see that almost all the questions on the exam were exactly what I found in their Dumps.
Anastasia Jul 11, 2025
You are right…It was amazing! The Cramkey Dumps were so comprehensive and well-organized, it made studying for the exam a breeze.
Melody
My experience with Cramkey was great! I was surprised to see that many of the questions in my exam appeared in the Cramkey dumps.
Colby Jul 9, 2025
Yes, In fact, I got a score of above 85%. And I attribute a lot of my success to Cramkey's dumps.
Question 34

The data governance team is reviewing code used for deleting records for compliance with GDPR. They note the following logic is used to delete records from the Delta Lake table named users.

Questions 34

Assuming that user_id is a unique identifying key and that delete_requests contains all users that have requested deletion, which statement describes whether successfully executing the above logic guarantees that the records to be deleted are no longer accessible and why?

Options:

A.

Yes; Delta Lake ACID guarantees provide assurance that the delete command succeeded fully and permanently purged these records.

B.

No; the Delta cache may return records from previous versions of the table until the cluster is restarted.

C.

Yes; the Delta cache immediately updates to reflect the latest data files recorded to disk.

D.

No; the Delta Lake delete command only provides ACID guarantees when combined with the merge into command.

E.

No; files containing deleted records may still be accessible with time travel until a vacuum command is used to remove invalidated data files.

Question 35

The data engineering team is migrating an enterprise system with thousands of tables and views into the Lakehouse. They plan to implement the target architecture using a series of bronze, silver, and gold tables. Bronze tables will almost exclusively be used by production data engineering workloads, while silver tables will be used to support both data engineering and machine learning workloads. Gold tables will largely serve business intelligence and reporting purposes. While personal identifying information (PII) exists in all tiers of data, pseudonymization and anonymization rules are in place for all data at the silver and gold levels.

The organization is interested in reducing security concerns while maximizing the ability to collaborate across diverse teams.

Which statement exemplifies best practices for implementing this system?

Options:

A.

Isolating tables in separate databases based on data quality tiers allows for easy permissions management through database ACLs and allows physical separation of default storage locations for managed tables.

B.

Because databases on Databricks are merely a logical construct, choices around database organization do not impact security or discoverability in the Lakehouse.

C.

Storinq all production tables in a single database provides a unified view of all data assets available throughout the Lakehouse, simplifying discoverability by granting all users view privileges on this database.

D.

Working in the default Databricks database provides the greatest security when working with managed tables, as these will be created in the DBFS root.

E.

Because all tables must live in the same storage containers used for the database they're created in, organizations should be prepared to create between dozens and thousands of databases depending on their data isolation requirements.
