Digital Engineering Exam Questions &
Answers 2023/2024
Which of the following requires integration of model and simulation activities into program planning and
engineering efforts? - ANSWER-- Defense Acquisition Guide (DAG) Chapter 4
- DoD Digital Engineering Fundamentals
*- DoDI 5000.02*
- Weapon System Acquisition Reform Act (WSARA) of 2009
Technical Coherency is the clear understanding of the relationships between data and digital artifacts, to
communicate, rationalize, and integrate the interactive relationships, across diverse systems, throughout
a project's life cycle. - ANSWER-*- True*
- False
Which of the following best describes Model Validation/Accreditation of the Model-Test-Model
approach? - ANSWER-*- Model Developer provides sufficient evidence to a tester that a simulation
adequately replicates field testing*
- Model input parameters are carefully matched with field trial output values
- Model Developer improves test design by addressing issues of efficiency and effectiveness
- Identification of the model weaknesses and areas for model improvement
Which THREE of the following are rules of model credibility? (Select all that apply.) - ANSWER-- Avoid
pseudoscience
*- Use models to clarify, not obscure*
*- Aim for transparency*
*- Focus the analysis*
A methodology is a collection and application of related Process, Methods, and Tools (PMT) to a class of
problems that all have something in common. - ANSWER-*- True*
- False
, Which of the following is true of a Data Model? - ANSWER-- A concept that forms part of a data element
*- Organizes data elements and describes how they relate to one another*
- An atomic unit of data with precise meaning
- Consists of a single, two-dimensional array of data elements
Which of the following best describes the Statement of Work (SOW)? - ANSWER-*- The portion of a
contract which establishes and defines all contract requirements for contractor's efforts to include:
Digital Engineering (DE) requirements for delivery of models, simulations, data, tools, infrastructure,
DSM, and a Digital Twin.*
- A government-prepared document that establishes a broad description of the government?s required
performance objectives.
- A performance-based acquisitions document that describes the required results in clear, accurate and
objective terms with measurable outcomes.
- A government-prepared document that states the overall performance objectives and describes, as
applicable, any DE approach that includes the development, maintenance, and delivery of digital
artifacts.
Which of the following factors are limitations of a document based approach? - ANSWER-*NOT RIGHT*
- Places the model as the master
- Uncovers defects early in the development life cycle
- Uncovers defects late in the development life cycle
*- Models and simulations are included in documentation*
Which of the following is true about the Modular Open System Approach (MOSA)? - ANSWER-- Produced
or generated from the Digital System Model (DSM) and the Digital Thread
- Includes the technical exchange of information and the end-to-end operational effectiveness of that
exchange
- Formed from models and/or analytics that have a predefined methodology
*- Allows design and production tasks to be done independently by groups that do not have to be part of
the same firm*
