Options :

A : a trade study

Answer: A

Question 4

Choose the correct answer. An engineering learn has been charged to design and build an embedded real-time control system using COTS (Commercial Off-The-Shelf) purchased components where possible A technical risk for such a control system is that the system will miss (i.e . fail to respond to) critical inputs The project has the additional risk that there may not be any components on the market that will meet both timing and cost constraints Given this, what information must be in the model before the engineering team can begin selecting and procuring COTS components?

Options :

A : timing constraints for all behaviors involved in responding to a critical input

B :

(1) liming constraints for all behaviors involved in responding to a critical input (2) total system production cost provided by the customer

C :

(1) minimum period of time between any two successive critical inputs (2) maximum acceptable time to produce all outputs for a critical input (3) allocation of (2) to all behaviors involved in responding to a critical input (4) total system production cost provided by the customer

D :

(1) minimum period of time between any two successive critical inputs (2) maximum acceptable time to produce ail outputs for a critical input (3) allocation of (2) to all behaviors involved in responding to a critical input (4) total system production cost provided by the customer (5) allocation of (4) to system components

E :

(1) minimum period of time between any two successive critical inputs (2) maximum number of critical inputs that will arrive in a given time interval (3) maximum acceptable time to produce all outputs for a critical input (4) allocation of (3) to all behaviors involved in responding to a critical input (5) total system production cost provided by the customer (6) allocation of (5) to system components

Answer: E

Question 5

Choose the correct answer For a system with stringent real-time requirements and power-consumption constraints, which concern would lead the designer to employ the MARTE profile?

Options :

A : ensuring traceability between structure and behavior

B : ensuring traceability between requirements and structure

C : ensuring that the structure could be precisely modeled and that analysis was supported

D :

ensuring that the relationship between system response time and power consumption could be captured in a parametric diagram
