Question 1

Which of the statements is most true to the problem domain?

Accepted Answer

The problem domain is where we use logical descriptions of a system.

Answer

The problem domain is where we describe what the system elements will look like and how they will be manufactured.

Answer

The problem domain contains descriptions of the system elements and their interconnections.

Question 5

What is/are true about a system?

Accepted Answer

All are true

Answer

A system comprises internal system elements.

Answer

There are interconnections between elements in a system

Answer

There are interconnections between system elements and an external system boundary

Question 6

What is/are true about the mission of the system?

Accepted Answer

All are true

It represents the start point of the design process

Answer

It is the purpose of the system

Answer

It provides the basis for the ultimate test of the system

Question 7

A logical description expresses what the system will do, how well it will do it, how it will be verified, under what conditions it will perform, and what other systems will be involved with.

Accepted Answer

true

Answer

false

Question 8

A physical description relates to the system elements and explains what the elements are, how they look, and how they are to be manufactured, integrated, and verified.

Accepted Answer

true

Answer

false

Question 9

What is/true about the Pre-acquisition Phase?

Accepted Answer

All are true

Answer

The Pre-acquisition Phase determines the feasibility or cost-effective of the system

Answer

The life cycle begins in the Pre-acquisition Phase with an idea from business planning

Answer

The Pre-acquisition Phase confirms the resources spending on the system

Question 10

The system remains in service during the Utilization Phase until...

Accepted Answer

All are true

Answer

the business has no further need for it

Answer

it no longer can meet the functions required of it by the organization

Answer

it is no longer cost-effective to keep it in service

Question 11

Which ONE of the major reviews formalizes the Preliminary Design?

Accepted Answer

Preliminary Design Review

Answer

Formal Qualification Review

Answer

Physical Configuration Audit

Answer

Conceptual Design Review

Question 12

Choose the CORRECT statement with regard to the perception that system engineering (SE) adds unnecessary complexity, cost, and time to development projects.

Accepted Answer

SE efforts can result in an increase in early costs but can result in significant cost savings later in construction and/or production.

Answer

SE adds unnecessary complexity, cost, and time to development projects--SE is actually an overhead that cannot be justified.

Answer

SE efforts early in acquisition cannot result in significant cost savings later in construction and/or production.

Answer

The perception that SE adds unnecessary complexity, cost, and time to development projects is incorrect because implementing SE is actually cheap and simple.

Question 13

Which ONE is CORRECT about the effect of the systems engineering on the cost of the system?

Accepted Answer

The focus of systems engineering on the entire system life cycle produces savings over the entire life cycle.

Answer

The additional effort in systems engineering means that the system will always cost more over its life cycle.

Answer

Systems engineering reduces the cost of each phase and activity in the system life cycle.

Answer

Systems engineering reduces the cost of the Acquisition Phase.

Question 14

Forward traceability is that the design decisions can be traced from any given system-level requirement down to a detailed design decision

Accepted Answer

true

Answer

false

Question 15

Any individual design decision must be associated with at least one higher-level requirement is called Backward Traceability.

Accepted Answer

true

Answer

false

Question 16

Which ONE is CORRECT with regard to system optimization and balance?

Accepted Answer

The system performance is the most importance, not the individual performance of subsystems.

Answer

To achieve optimal subsystem performance, the system performance may need to be suboptimal.

Answer

The subsystem performance is the most importance, not the performance of the system

Answer

Systems engineering focuses on optimizing component and subsystem performance so that the resulting system performance is optimal.

Question 17

Which One is Not the character of Systems Engineering

Accepted Answer

Bottom-Up Approach

Answer

System Optimization and Balance

Answer

Requirements Engineering

Answer

Focus on Life Cycle
