1. Which of the following is not a basic systems engineering concept?

 

1. Define need before function
2. Define function before requirements
3. Developing a prototype based on the solution to a previous similar problem.
4. Define requirements before seeking answers
5. Examining alternatives before selecting an answer
6. All of the above
7. g. None of the above
8. d and e only

Answer: G.

All of the concepts provided are necessary in a basic systems engineering.

2. In the systems development life cycle, software engineering:

 

1. implements a transfer function that matches interface constraints that are previously defined by the systems design team.
2. is a domain or specialty engineering task
3. is at the same hierarchical level as integrated logistics support
4. all of the above

e .none of the above

1. a and b only
2. b and c only

Answer: A

The software engineering aims to find a solutions to the constraint defined in the systems design.

3. Concept exploration, feasibility studies, and pre-systems definitions are each terms that apply to the phase of design in which the objective is to seek revolutionary improvements in products and services. Which of the following questions are investigated during pre-systems definition?

 

a .Is the program technically feasible?

1. Are the costs within acceptable bounds?
2. Are the risks within acceptable bounds?
3. Is the potential profitability sufficient?
4. Are the requirements fully defined?
5. How many lines of code are in the final product?
6. g. All of the above.
7. None of the above
8. a, b, c, and d only
9. e and f only

Answer: G

During the pre-systems definition, all of these questions are necessary to acquire viability, consistency and cost effectiveness.

4. All candidate solutions to a system design problem must conform to an identical logical model. Which of the following are required characteristics of the logical model?
5. conceptual integrity
6. lack of complication
7. form follows function
8. All of the above
9. None of the above
10. a and b only
11. a and c only
12. b and c only

Answer: F

The logical model has meet reliability and consistency in design both of which leads to integrity and simplicity.

5. Which of the following is NOT a factor in maintainability?

 

1. time required for fault detection
2. b. mean time between failures
3. time required for repair
4. time required to restore function following repair
5. time required for fault isolation
6. All of the above.
7. None of the above.

 

Answer: B

Maintainability deals with fault recovery and not mean time between faults.
