Architectural Design Questions and Answers

Q: The architectural model generally is derived from which of the following sources ?(i) Information about application domain for software.(ii) Data flow diagram or analysis classes (along with their relationships and collaborations)(iii) Availability of design patterns/frameworks

The architectural model draws on (i), (ii) and (iii).Pressman names three sources for the architectural model: information about the application domain for the software to be built, specific requirements model elements such as data flow diagrams or analysis classes with their relationships and collaborations, and the availability of architectural styles and patterns.Options that exclude any one of these leave out a source the method relies on.

Q: Which of the following software architecture is prone to 'single point of failure' vulnerability ?

The architecture prone to a single point of failure is Client-server.In a client-server system all clients depend on a central server. If the server fails, every client loses the service at once, which is the definition of a single point of failure (unless the server is replicated).Peer-to-peer systems have no central node: any peer can serve others, so the failure of one does not stop the network. Service-oriented and distributed-object architectures spread functions across many independent services or objects, so they are not, by design, tied to one point of failure.

Q: Architectural models that may be developed may include :................ models that shows relationships, such as data flow, between the sub-systems.

The models are relationship models.Sommerville lists architectural models that may be developed: a static structural model of the sub-systems, a dynamic process model of the run-time processes, an interface model of sub-system interfaces, relationship models showing relationships such as data flow between the sub-systems, and a distribution model.Static structural, dynamic process and interface models are the other entries in that list, each with a different purpose.

Q: Architectural models that may be developed may include : A ................. model that shows how the system is organised into processes at run-time.

The model is a dynamic process model.Among the architectural models a designer may develop, a dynamic process model shows how the system is organised into processes at run-time, which may differ from its static organisation into components.A static structural model shows the subsystems or components developed as separate units. An interface model defines the services offered by each subsystem through its public interface, and a relationships model shows relationships such as data flow between subsystems. Neither shows the run-time process organisation.

The architectural model generally is derived from which of the following sources ?

(i) Information about application domain for software.
(ii) Data flow diagram or analysis classes (along with their relationships and collaborations)
(iii) Availability of design patterns/frameworks

A.(i) and (ii) only but not (iii)
B.(i) and (iii) only but not (ii)
C.(ii) and (iii) only but not (i)
D.(i), (ii) and (iii)

The architecture prone to a single point of failure is Client-server.

In a client-server system all clients depend on a central server. If the server fails, every client loses the service at once, which is the definition of a single point of failure (unless the server is replicated).

Peer-to-peer systems have no central node: any peer can serve others, so the failure of one does not stop the network. Service-oriented and distributed-object architectures spread functions across many independent services or objects, so they are not, by design, tied to one point of failure.

Answer: D

The models are relationship models.

Sommerville lists architectural models that may be developed: a static structural model of the sub-systems, a dynamic process model of the run-time processes, an interface model of sub-system interfaces, relationship models showing relationships such as data flow between the sub-systems, and a distribution model.

Static structural, dynamic process and interface models are the other entries in that list, each with a different purpose.

Answer: B

The model is a dynamic process model.

Among the architectural models a designer may develop, a dynamic process model shows how the system is organised into processes at run-time, which may differ from its static organisation into components.

A static structural model shows the subsystems or components developed as separate units. An interface model defines the services offered by each subsystem through its public interface, and a relationships model shows relationships such as data flow between subsystems. Neither shows the run-time process organisation.
