1. What functionality of Requirement Management Tool (RMT) is depicted by the statement: “the tool should be able to automatically detect relations between artifacts. For example information retrieval techniques, monitoring of change history, naming schemas or model transformations.”
a) Automatic Link Detection
b) Documentation Support
c) Graphical Representation
d) Automatic Link Creation and Change
Explanation: DOORS is one such tool that supports Automatic Link Detection.
2. According to a statistical report: “over 30% of all software projects are cancelled before completion and over 70% of the remainder fail to deliver expected features”. What must be the reason for such a situation ?
a) Poor change management
b) Poor requirements management
c) Poor quality control
d) All of the mentioned
Explanation: Fundamental to the problem mentioned in the statistical report is poor requirements management. Option a and c are its sub parts.
3. Which of the following diagram is not supported by UML considering Data-driven modeling ?
a) Activity
b) Data Flow Diagram (DFD)
c) State Chart
d) Component
Explanation: DFDs focus on system functions and do not recognize system objects.
4. _________________ allows us to infer that different members of classes have some common characteristics.
a) Realization
b) Aggregation
c) Generalization
d) dependency
Explanation: Generalization is an everyday technique that we use to manage complexity.This means that common information will be maintained in one place only.
5. One creates Behavioral models of a system when you are discussing and designing the system architecture.
a) True
b) False
Explanation: Structural models of software display the organization of a system in terms of the components that make up that system and their relationships.
6. ______________ & ______________ diagrams of UML represent Interaction modeling.
a) Use Case, Sequence
b) Class, Object
c) Activity, State Chart
d) All of the mentioned
Explanation: Use case modeling is mostly used to model interactions between a system and external actors.Sequence diagrams are used to model interactions between system components, although external agents may also be included.
7. Which level of Entity Relationship Diagram (ERD) models all entities and relationships ?
a) Level 1
b) Level 2
c) Level 3
d) Level 4
Explanation: Level 1 ERD models all data objects (entities) and their “connections” to one another while Level 3 ERD models all entities, relationships, and the attributes that provide further depth. Thus option b is correct.
8. ___________ classes are used to create the interface that the user sees and interacts with as the software is used.
a) Controller
b) Entity
c) Boundary
d) Business
Explanation: Boundary classes are used to create the interface that the user sees and interacts with as the software is used
9. Which of the following statement is incorrect regarding the Class-responsibility-collaborator (CRC) modeling ?
a) All use-case scenarios (and corresponding use-case diagrams) are organized into categories in CRC modelling
b) The review leader reads the use-case deliberately
c) Only developers in the review (of the CRC model) are given a subset of the CRC model index cards
d) All of the mentioned
Explanation: All participants in the review (of the CRC model) are given a subset of the CRC model index cards.
10. A data object can encapsulates processes and operation as well.
a) True
b) False
Explanation: A data object encapsulates data only. There is no reference within a data object to operations that act on the data.
