3. Which of the following are true?
a) A unit’s responsibilities are usually indicated by various connections and by the respective names
b) A unit’s relationships are usually indicated in part by its name and in part by the symbols used to represent it in various diagrams
c) All of the mentioned
d) None of the mentioned
Answer: d
Clarification: A units responsibilities are indicated in part by its name and in part by the symbols used to represent it in various diagrams whereas a units relationship is indicated by various connections and by the respective names.

Clarification: Interface specification as descriptions of communication includes syntax, semantics, pragmatics.
5. Which of the following is false about interface specifications?
a) The syntax of communication specifies the elements of medium and the ways they may be combined to form legitimate messages
b) The semantics of a communication medium specify the meaning of messages
c) All of the mentioned
d) None of the mentioned
Answer: d
Clarification: All the mentioned statements are true and so no false statements can be extracted.
6. Which of the following is true?
a) A precondition is an assertion must be true at the completion of an activity
b) A post condition is an assertion must be true at the initiation of an activity
c) An interface specification should cover syntax, semantics, pragmatics of communication between module and its environment
d) All of the mentioned
Answer: c
Clarification: The correct statement of the incorrect ones are A precondition is an assertion must be true at the initiation of an activity whereas a post condition is an assertion must be true at the completion of an activity.

c) All of the mentioned
d) None of the mentioned
Answer: d
Clarification: All the mentioned are false correct one are, The boxes diagram refer to the software or data store components and The line in the diagram refer to the interaction relationship between components.
9. Which of these signifies the heuristics of Architectural specifications?
a) Write good technical prose when specifying architectures
b) Use a template to specify interface
c) Keep boxes and line simple
d) Use a template to specify interface & Write good technical prose when specifying architectures
Answer: d
Clarification: Keep boxes and line simple are the heuristic for box and line diagram and not for architectural specification
10. Which of these signifies the heuristics of Box and Line diagram?
a) Make the box and lines simple
b) Use symbol consistently in different diagram
c) Use a template to specify interface
d) Make the box and lines simple & Use symbol consistently in different diagram
Answer: d
Clarification: Use a template to specify interface is a heuristic for architectural specification.
