What is a benefit of utilizing the IBM Data Virtualization service?

IBM Data Virtualization provides a single, unified query interface across multiple, heterogeneous data sources without physically moving the data. A primary benefit of this approach is the ability to establish a centralized point for data access and governance. Administrators can define and enforce security policies, access controls, and data masking rules on virtual tables within the Data Virtualization service, ensuring consistent governance across all underlying data sources from a single location. This simplifies security management and ensures compliance.

A. Data can be copied to the platform quickly and easily.

This is incorrect. The core principle of data virtualization is to query data in-place, thereby avoiding the need to copy or move it, which saves time and storage costs.

B. Workloads can bypass data source security for faster execution.

This is incorrect. Data Virtualization respects and integrates with source security. It does not bypass security controls; instead, it provides an additional layer of centralized security and governance.

C. Discover and classify sensitive information.

This is incorrect. While governed virtual data can be profiled, the primary service for automated discovery and classification of sensitive information in IBM Cloud Pak for Data is Watson Knowledge Catalog.

1. IBM Cloud Pak for Data Documentation - Data Virtualization Overview: "With the Data Virtualization service

you can use a single connection to any data source to query all of your data... You can use Data Virtualization to govern access to your data in a central

secure

and monitored environment." This directly supports the concept of centralized governance (Answer D).

2. IBM Cloud Pak for Data Documentation - Governing virtual data: "You can govern virtual data in Watson Knowledge Catalog in the same way that you govern other data assets... When you virtualize data

the virtual tables are automatically added to the default catalog." This shows that governance is a key feature

but also distinguishes the virtualization service from the cataloging service (Why C is incorrect).

3. IBM Cloud Pak for Data Documentation - Data Virtualization Overview: "Data Virtualization is designed to query data sources directly and to minimize data movement." This statement explicitly contradicts the idea of copying data (Why A is incorrect).
