WGU Updated Information-Technology-Management Exam Questions and Answers by byron

Increased Carbon Emissions:

Technology relies on electricity, often generated from fossil fuels, leading to higher carbon emissions.

The production, transportation, and disposal of electronic devices contribute to the carbon footprint.

Increased Energy Consumption:

Expanded use of technology leads to higher energy demands for operating servers, cooling data centers, and powering devices.

The rise of 24/7 technology operations has amplified global energy consumption.

Why Other Options Are Incorrect:

Option A:The lifespan of technology tends to shorten due to rapid advancements and planned obsolescence.

Option C:While more devices are purchased, this does not directly indicate an ecological result.

Option D:Electronic waste has increased, not decreased, due to growing technology adoption and lack of recycling initiatives.

Understanding the Development Phase in SDLC:

The development phase involves translating system design specifications into actual software.

This includes coding the system using programming languages and integrating modules as per the design.

Why Other Options Are Incorrect:

Option B:Describes the maintenance phase, which focuses on updates and corrections post-deployment.

Option C:Relates to the testing phase, where interoperability and functionality are verified.

Option D:Refers to the implementation phase, where the system is deployed for user operations.

Importance of Corporate Culture in Technology Adoption:

Organizational culture directly influences employees’willingness to adopt new technologies.

Resistance often stems from fear of change, lack of trust in technology, or inadequate training.

Steps Before Implementing a Unified Communications System:

Assess the corporate culture to identify barriers to adoption.

Develop a change management strategy to address concerns and align the system with company values.

Incorrect Options Analysis:

A. Pilot Testing:Useful later in implementation, but not the first step.

B. Employee Accessibility:Important but secondary to addressing cultural barriers.

D. Competitors’ Systems:Irrelevant to internal resistance issues.

Definition of ERP Systems:

ERP systems facilitatedata sharing and process integrationacross 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.
