Exam Topics

In this section, you can find the details of the technical topics and subject areas covered by the exam.

Use Cases

In this section, the candidate should demonstrate that they understand the project in which they are working, and the main use cases implemented during this project.

We recommend focusing on the use cases that provide the highest business impact. Use case descriptions should be more specific but always with a business focus, as an example:

  • Unified view of risk exposure for compliance applications
  • Single View of customer information for a customer service desktop application
  • Semantic Layer for the Data Lake
  • Abstraction layer to migrate an EDW to the Cloud
  • etc.

For each use case, it can be useful to provide some technical information such as the relevant data sources for each of them or the data publishing method selected.

How to prepare

As a reference, for a description of the most common data virtualization use cases and patterns, the student can attend the Data Virtualization Architect course (DEN80EDU07A). In addition to it, the Solutions area of the Denodo website contains useful content about this topic (https://www.denodo.com/en/solutions/overview).

Business goals and objectives

In this section, the examinee should demonstrate their knowledge of the main business goals of the project in which they are working, and it will mainly depend on the specific business domain and requirements.

How to prepare

For guidance about how to define business goals and objectives the student can visit some real customer cases available at the following link at the Denodo website: https://www.denodo.com/en/customers

Architecture

In this section, the candidate should demonstrate that they understand the architecture graphic attached to the exam. Please, see the section “File Upload” for more information.

How to prepare

The student can see as a reference some data virtualization architecture samples in the materials of the Denodo Data Virtualization Architect course (DEN80EDU07A).

Project Details

In this section, the candidate should demonstrate that they understand the different roles and responsibilities of the persons participating during the project implementation. Also, the candidate has to provide details of her/his specific participation in the project.

How to prepare

The student can find information about the different roles in a typical data virtualization deployment in the Denodo Expert Trial “Denodo Development Lifecycle” (https://community.denodo.com/expert-trails) and in the “Denodo Project Management” course (DEN80EDU19DS).

Also, the student can visit some videos describing real customer deployments that are available on the Denodo website (https://www.denodo.com/en/resources, search for webinars) where in some cases the customer highlights the main challenges during the deployment.

For samples of other projects, the student can visit the customer cases available on the Denodo website (https://www.denodo.com/en/customers).

The student can visit some videos describing real customer deployments that are available on the Denodo website (https://www.denodo.com/en/resources, search for webinars) where in many cases the customer highlights the experience and lessons learned during the project.

Answering the different question types

There are different types of questions: “Recording” for an audio/video description, “File upload” for the architecture graphic and for questions that have to be answered in writing. We include here a screenshot for every question type as an example:

Recording

The user has to click on “Skip and Start Video Recording” to initiate the recording that will last 3 minutes maximum. Once completed the user has to click on “Stop Recording”, the recording will be saved and the system will go to the next question.

File Upload

The user has to upload a file to describe the experience as a data architect in a data virtualization project. You can find the template here. It you cannot use this template, you can attach a document that includes the answer to the following questions:

  • Project Description
    • Customer Industry
    • Project title (if any)
    • Description of the project including main use cases implemented
    • Architecture graphic. It should include at a minimum:
    • Key data sources integrated in the project
    • Main consumer applications
    • Interaction with other tools/applications (e.g. data governance, data quality, etc.)
    • Security details (e.g. integration with identity providers, key vaults, policy servers, etc.)
    • Details of the deployment (whether it is on-premises or in the cloud, hybrid, multi-cloud, etc.)
    • There is no need to include in the architecture the different environments (development / pre-production / production), for the sake of making the graphic easier to understand the production environment suffices.
  • Project Technical Details
    • Information about data modeling best practices in your project: implementation of a canonical model, usage of interface views, model import from data modeling tools, etc.
    • Indicate whether any custom extensions were used in your project: custom functions, store procedures, policy handlers, custom wrappers, tag-based policies
    • Describe the performance configuration in your project: data movement targets, possible integration with a MPP engine, configuration of summaries, etc.
    • Describe the caching configuration and policies used in your project.
    • Provide a brief analysis of the workload expected in your project and information about the sizing of your solution: type of queries, volumetric information (e.g. #concurrent queries, etc.), possible usage of Resource Manager, sizing details.
    • Describe briefly the security architecture in your project: security protocols configured, integration with Identity Providers, configuration of SSO, etc.
    • Describe the publishing options deployed: JDBC, OData, REST, GeoJSON, GraphQL, etc.
    • Describe the Data Catalog configuration and possible integration with Data Governance tools (if any).
    • Provide information about the Integration with Version Control Systems and metadata migration policies between environments.

Once the candidate has completed all the questions she/he has to click on the “Finish Test” button and the test will be finished.
