WGU Information Technology Management QGC2 Exam Questions

Analysis Phase in SDLC:

The analysis phase involves gathering detailed requirements from stakeholders to ensure the system aligns with business needs.

This phase translates high-level goals into specific functions, operations, and deliverables.

Key Activities in the Analysis Phase:

Engaging stakeholders and subject-matter experts.

Documenting requirements in detail (e.g., user stories, use cases).

Identifying potential constraints and refining goals.

Incorrect Options Analysis:

A . Physically constructing software: Part of the development phase.

B . Desired features descriptions: Happens in the design phase.

D . High-level strategy: Belongs to the planning phase.

Comprehensive and Detailed Explanation From Exact Extract:

Online Transaction Processing (OLTP) systems are designed to support high volumes of short, atomic, real-time transactions such as order entry, banking operations, or retail point-of-sale activities. The fundamental process enabling effective OLTP is real-time data processing, where each transaction is processed immediately as it is entered, and the database is updated instantly.

Real-time processing in OLTP systems ensures:

Immediate validation and recording of each transaction

Up-to-date data for subsequent transactions and queries

Support for concurrent users performing many small transactions

Option A (Batch file transfers) belong to batch processing, where data is accumulated and processed at set intervals, which conflicts with the immediate nature of OLTP.

Option C (Strategic budgetary planning) is part of long-term planning and not directly a technical process supporting OLTP.

Option D (Manual data entry) can occur in many systems and is not specific to OLTP nor is it the key process that defines OLTP capability.

Thus, real-time data processing is the process that directly supports effective OLTP systems.

In a unified communications system, communications media refers to the actual method by which communication takes place. A key example is a software-based phone that uses Voice over Internet Protocol (VoIP), which allows users to make phone calls through the internet instead of relying on traditional analog systems.

Option B: Incorrect---mobile conferencing devices are tools, not the core communications media.

Option C: Incorrect---signal converters are hardware for compatibility, not communications media.

Option D: Incorrect---traditional phones are legacy hardware, not unified digital media.

Thus, communications media in UC systems is represented by a software-based phone using VoIP.

Purpose of a Prototype:

A prototype is an interactive model that demonstrates how a system or interface works.

It allows clients to experience the functionality and interaction before full-scale development.

Why Other Options Are Incorrect:

Option A: Prototypes are not detailed development instructions.

Option C: Prototypes are not blueprints but are functional models.

Option D: Prototypes are dynamic and interactive, unlike static examples.

Definition of ERP Systems:

ERP systems facilitate data sharing and process integration across multiple departments within an organization, such as HR and purchasing.

These systems improve coordination and decision-making by maintaining a single source of truth.

Example of ERP Usage:

If the HR department needs to coordinate with the purchasing team for new employee resources, ERP ensures both have access to relevant information like budgets and procurement requirements.

Incorrect Options Analysis:

A . Executive Support (ES): Caters to strategic decision-making, not operational collaboration.

B . Geographic Information System (GIS): Deals with spatial and geographical data, not departmental coordination.

D . Customer Relationship Management (CRM): Manages customer interactions, not internal department processes.
