App Dev Reviewer - Midterm

Which of the following best describes design pattern?

• patterns that deals with object creation mechanisms, trying to create objects in a manner suitable to a certain situation

• reusable solutions to commonly occurring problems in software design

• it describes the element that make up the design, their relationships, responsibilites, and collaborations.

• it describes how objects are composed into a larger groups and explain how to assemble objects and classes into larger structure.

Software is hard to change because every applied change will affect many parts of the software. Which characteristic of poor software design is described?

• Rigidity

• Fragility

• Immobility

• Variety

it is a set of guidelines to be followed that helps developers arrange methods an data structures into classes.

• Design Principle

• Design Pattern

• Design Structure

• Design Requirements

when applying changes to the software, unexpected parts of the software breaks. Which characteristic of poor software design is described?

• Rigidity

• Fragility

• Immobility

• Variety

This design principle suggests that each software module should have only one (1) reason to change

• Single Responsibility Principle

• Open-Closed Principle

• Liskov Substitution Principle

• Interface Segregation Principle

this category of design patter describes how communication happens between objects

• Creational Pattern

• Structural Pattern

• Behavioral Pattern

• Singleton Pattern

this category of design patter describes how objects are composed into larger groups and explain how to assemble objects and classes into larger structures

• Creational Pattern

• Structural Pattern

• Behavioral Pattern

• Singleton Pattern

this feature of design pattern describes the responsibilities and collaborations of element that make up the design

• Pattern Name

• Problem

• Solution

• Consequences

the software modules are hard to reuse in another software because these cannot be extracted from the current software. Which characteristic of poor software design is being described?

• Rigidity

• Fragility

• Immobility

• Variety

this design principle states that when there are new software requirements, the new behavior must be added by deriving a new class without modifying the existing class

• Single Responsibility Principle

• Open-Closed Principle

• Liskov Substitution Principle

• Interface Segregation Principle
