WGU C182 UPDATED COMPREHENSIVE EXAM QUESTIONS
AND ANSWERS MARKED A+
✔✔End users assisted by developers; systems tested with simulated data - ✔✔Alpha
testing
✔✔End user test the system in operational setting to see if it's useful - ✔✔User
Acceptance
✔✔End user tests the system without help from developers; using actual data - ✔✔Beta
testing
✔✔SDLC - ✔✔Software Development Life Cycle
✔✔SDLC aka - ✔✔Staircase or most referred to as waterfall
✔✔Preliminary Investigation Step # - ✔✔Step 1 in SDLC
✔✔Analysis Step # - ✔✔Step 2 in SDLC
✔✔Logical Design Step # - ✔✔Step 3 in SDLC
✔✔Physical Design Step # - ✔✔Step 4 in SDLC
✔✔Implementation Step # - ✔✔Step 5 in SDLC
✔✔Maintenance Step # - ✔✔Step 6 in SDLC
✔✔SDLC - Preliminary Investigation - ✔✔Problem or opportunity that a new system
could be developed to address. During this first step, the team assesses the feasibility
of the proposed project and selects a development methodology
✔✔SDLC - Analysis - ✔✔Determine user requirements for new system and develop
logical system models (i.e., graphic displays that demonstrate the relationships between
resources, activities, and outputs and outcomes)
✔✔SDLC - Logical Design - ✔✔Models developed during the second step are revised
to ensure that the new system will meet the user requirements identified in the first step
✔✔SDLC - Physical Design - ✔✔Logical models converted but are still abstractions of
the system that will be built later, but they are now more complete and may include
network maps and descriptions of servers and other devices to be used in the system
, ✔✔SDLC - Implementation - ✔✔Programmers begin converting the models from the
previous steps into the actual system, for instance, by developing databases and other
software programs that will be needed. This step also includes installing hardware,
testing the system, and training the end users
✔✔SDLC - Maintenance - ✔✔Modifications or corrections to the system are made
✔✔Three main categories of a database? - ✔✔Flat file, relational and hierarchical
✔✔Flat file - ✔✔One large single table without the relations between tables that a
relational format provides
✔✔Relational Database - ✔✔Multiple tables (relations) with interrelated fields
✔✔Hierarchical Databases - ✔✔Organizes data using a tree-like or organizational chart
type structure (the child can only have one parent)
✔✔MVC stands for? - ✔✔Model-View-Controller
✔✔What is MVC? - ✔✔Software development technique used in the implementation of
user interfaces which include the model, the view and the controller
✔✔Model in MVC - ✔✔Software logic, business rules and application data
✔✔View in MVC - ✔✔User interface (i.e.; colors, fields...ect)
✔✔Controller in MVC - ✔✔Communication between the user and the model
✔✔Which component facilitates communication between the other two components in
the MVC architecture model? - ✔✔View
✔✔Types of system conversion (SDLC) - ✔✔Direct, Parallel, Pilot, Phased
✔✔Direct Conversion - ✔✔The old system is "turned off" and the new system is "turned
on" at a specific date and time
✔✔Parallel Conversion - ✔✔Period of time in which both systems (the old and the new)
are operating concurrently
✔✔Pilot Conversion - ✔✔Starting the conversion with a portion of the end users, for
instance in a specific geographic region or a department in an organization
✔✔Phased Conversion - ✔✔Deploys a subset of the system first, rather than deploying
the whole system at once
