GCP-ADP Data Management Practice Test 2 — 15 Questions

Question 1

You have a Data Catalog taxonomy that you want to share across multiple projects. How do you achieve this?

Accepted Answer

Define it in a central project and share access. You create the taxonomy in a central host project and grant permissions to other projects to use it.

Answer

Move the taxonomy to the Organization node

Answer

Duplicate the taxonomy in each project

Answer

Use Cloud Resource Manager to link them

Question 2

What is the primary function of the 'Dataplex Discovery' process?

Accepted Answer

To automatically catalog and profile data. Discovery automatically scans and catalogs data assets in your storage to make them discoverable.

Answer

To manage VPC firewall rules

Answer

To run SQL queries

Answer

To migrate data to the cloud

Question 3

You need to ensure that a Dataplex user cannot view the contents of files in a GCS bucket registered as an asset. What is the minimal configuration?

Accepted Answer

Remove the Storage Object Viewer role from the user. You must remove the Storage Object Viewer role from the user for that specific bucket, even if they have Dataplex viewer roles.

Answer

Remove the user from the Dataplex Lake Viewer role

Answer

Create a Dataplex deny-policy

Answer

Delete the asset from Dataplex

Question 4

You need to track lineage for a BigQuery table populated by a Dataflow pipeline. How does Dataplex help?

Accepted Answer

Dataplex captures it automatically for supported services. Dataplex and Data Catalog integrate with BigQuery and Dataflow to capture lineage automatically when pipelines are correctly instrumented.

Answer

Lineage is not supported in Dataplex

Answer

You must use a third-party tool

Answer

You must manually enter the lineage in the Data Catalog UI

Question 5

When setting up a Dataplex Lake, you chose the 'Multi-region' location type. What is the implication of this choice?

Accepted Answer

It improves data availability and durability. Multi-region deployment increases availability and ensures data is replicated across multiple regions within the same geography.

Answer

It restricts access to users in a single region

Answer

It prevents the use of BigQuery datasets

Answer

It reduces the cost of storing data

Question 6

What is the role of the 'Dataplex Data Steward'?

Accepted Answer

To manage metadata, quality rules, and compliance. The Data Steward is responsible for defining metadata, managing quality rules, and ensuring data policies are met.

Answer

To write SQL queries for the business

Answer

To develop ETL pipelines

Answer

To manage the underlying infrastructure

Question 7

Which service allows you to view the schema and metadata of a BigQuery table that has been registered in Dataplex?

Accepted Answer

Data Catalog. The Data Catalog interface within Dataplex provides a unified view of metadata, including schemas.

Answer

Cloud Storage Console

Answer

Cloud Build

Answer

Cloud IAM console

Question 8

You want to enforce that all data in a specific Dataplex Zone must be encrypted with a Customer-Managed Encryption Key (CMEK). How do you enforce this?

Accepted Answer

Configure CMEK at the Lake/Zone creation level. When creating a Dataplex Lake or Zone, you can configure CMEK settings that apply to the underlying resources.

Answer

There is no way to enforce CMEK in Dataplex

Answer

Use a Dataflow job to re-encrypt

Answer

Apply it via an IAM policy

Question 9

You have data scattered across multiple projects and need to provide a unified data governance view. What is the recommended hierarchy?

Accepted Answer

One Lake, with assets added from multiple projects. You create one Lake, and within that Lake, you add assets from different projects (within the same organization).

Answer

A single GCS bucket for all data

Answer

Multiple Lakes, one per project, and manage them independently

Answer

One Lake per project, then use a project-linking tool

Question 10

A user complains they cannot see a Dataplex Lake in the console. You verify they have the 'Viewer' role on the project. What is missing?

Accepted Answer

They need the 'roles/dataplex.viewer' role. The user needs a specific Dataplex role (like Dataplex Viewer) to see the Dataplex resources in the UI.

Answer

They need to refresh their browser

Answer

They need the 'Owner' role

Answer

They need to be added to the project's whitelist

Question 11

Which of the following is NOT a benefit of using Dataplex?

Accepted Answer

High-frequency OLTP transaction support. Dataplex is for data governance and management, not for high-frequency low-latency transaction processing (OLTP).

Answer

Automated data discovery

Answer

Improved data compliance

Answer

Unified data management

Question 12

What does 'Data Lineage' show you in Dataplex?

Accepted Answer

The path the data took through the system. Data lineage tracks the origin, movement, and transformations of data as it moves through the pipeline.

Answer

The number of users accessing the data

Answer

The cost of storing data

Answer

The database schema version

Question 13

You need to move an asset from one Dataplex Zone to another. What is the correct procedure?

Accepted Answer

Delete the asset from the first zone and recreate it in the second. Assets are tied to a specific zone. To move an asset, you must remove it from the source zone and add it to the destination zone.

Answer

Update the IAM policy to include the new zone

Answer

Use the 'move' command in the CLI

Answer

Update the asset metadata to point to the new zone

Question 14

You need to share a BigQuery dataset across multiple organizations. What is the recommended approach using Dataplex?

Accepted Answer

Use Dataplex to aggregate the datasets in one Lake. Dataplex allows you to link cross-project and cross-org assets into a single lake, provided the appropriate IAM permissions are set.

Answer

Grant public access to the dataset

Answer

Copy all data to a single project

Answer

Export the data to CSV files

Question 15

You want to perform data quality checks on a BigQuery table that is updated daily. How should you schedule the Dataplex task?

Accepted Answer

Configure a CRON schedule on the task. Dataplex tasks can be triggered on a schedule using cron syntax, allowing for daily alignment with data updates.

Answer

Manually trigger via the UI

Answer

Wait for discovery to trigger it

Answer

Use Cloud Run to trigger the task
