Data Virtualization

The Data Virtualization exam evaluates candidates' proficiency in implementing and managing data virtualization solutions to integrate and access data from disparate sources in real-time. Data virtualization enables organizations to access and query distributed data sources as if they were a single, unified data layer, without the need for physical data movement or replication. This exam covers essential principles, techniques, and best practices related to data virtualization, including data integration, data federation, query optimization, and metadata management.

Who should take the exam?

  • Data Architects: Architects responsible for designing and implementing data integration and virtualization solutions to meet business requirements.
  • Data Engineers: Engineers tasked with implementing and maintaining data virtualization platforms and managing data access and integration processes.
  • Business Intelligence Developers: Developers interested in leveraging data virtualization to integrate and access data for BI and analytics purposes.
  • Data Analysts: Analysts seeking to access and analyze data from disparate sources using data virtualization tools and techniques.
  • IT Professionals: IT professionals involved in data management, integration, and governance initiatives within organizations.

Skills Required

  • Understanding of Data Integration Concepts: Knowledge of data integration principles, including data extraction, transformation, and loading (ETL), as well as data federation and virtualization.
  • Data Virtualization Technologies: Proficiency in implementing and configuring data virtualization platforms and tools, such as Denodo, Cisco Data Virtualization, or IBM Data Virtualization.
  • SQL and Query Optimization: Ability to write and optimize SQL queries to retrieve and manipulate data from virtualized data sources efficiently.
  • Metadata Management: Competence in managing metadata repositories and catalogs to track data lineage, quality, and usage across virtualized environments.
  • Business Intelligence and Analytics: Familiarity with business intelligence (BI) and analytics tools for querying, analyzing, and visualizing data accessed through data virtualization solutions.

Data Virtualization FAQs

Candidates who pass the exam receive a professional certificate in Data Virtualization, which verifies their expertise in implementing and managing virtual data solutions within modern data environments.

Yes, candidates are generally allowed to retake the exam after a mandatory waiting period, which is usually 14 to 30 days, depending on the certification body’s retake policy.

Yes, many certification providers offer the option to take the exam online through secure proctoring services, although some may also provide in-person testing centers.

Recommended materials include vendor documentation (e.g., Denodo Platform Guides), online certification courses, sample exams, whitepapers on virtualization architectures, and hands-on lab practice with supported platforms.

While there are no mandatory prerequisites, candidates should have a working knowledge of data integration concepts, SQL, APIs, and enterprise data platforms to ensure successful exam performance.

The exam duration usually ranges from 90 to 120 minutes. A minimum passing score of 70% is commonly required, although this may vary depending on the certifying organization.

Topics include architecture and concepts of data virtualization, integration of data sources, logical data modeling, performance tuning, security and governance, and tool-specific implementations such as Denodo or TIBCO.

The exam typically consists of 50 to 70 multiple-choice and scenario-based questions. Some certification providers may include practical lab tasks or case studies to assess hands-on knowledge.

The exam is designed to validate an individual’s understanding and application of data virtualization techniques, tools, and best practices in managing unified data access across multiple sources without physical data movement.

Professionals with experience in data integration, data architecture, business intelligence, or data engineering are ideal candidates. A background in database systems and familiarity with data modeling is also recommended.
