Free Practice Questions for WGU Information-Technology-Management Exam

Understanding Unified Communications Systems:

Unified Communications (UC) integrates multiple communication tools like voice, video, messaging, and collaboration tools into a single platform.

Its goal is to enhance real-time communication and collaboration within and outside the organization.

Reducing Latency:

UC reduces delays (latency) in communication by enabling instant messaging, video conferencing, and real-time collaboration tools.

This ensures faster decision-making and improves organizational efficiency.

Why Other Options Are Incorrect:

Option A: Managing customer expectations is more aligned with CRM systems.

Option C: Generating solutions involves creativity and innovation tools, not UC.

Option D: While UC improves efficiency, it does not specifically aim to make employees "comfortable."

Definition of Project Assumption:

A project assumption is a factor considered true, real, or certain without proof or demonstration during project planning.

Assumptions are critical for estimating resources, timelines, and risks.

Examples of Project Assumptions:

Availability of key resources or team members.

Stable technical infrastructure during project execution.

Incorrect Options Analysis:

A. Project Requirements: Specify what the project must achieve, not assumptions.

B. Project Theory: This is not a standard term in project management.

D. Project Objective: Refers to the desired outcomes, not underlying assumptions.

SNMP (Simple Network Management Protocol) is used for monitoring and managing network devices such as routers, switches, and servers. It allows administrators to gather network performance data and configure devices remotely.

Understanding the Bullwhip Effect:

The bullwhip effect occurs when small fluctuations in consumer demand lead to exaggerated changes in inventory levels up the supply chain.

Miscommunication or poor demand forecasting amplifies these effects, causing overproduction or stockpiling.

Why Other Options Are Incorrect:

Option B: Refers to supply chain optimization, which is unrelated to the bullwhip effect.

Option C: Describes the maker movement, not the bullwhip effect.

Option D: Describes the network effect, unrelated to supply chain dynamics.

Understanding Team Friction:

Team friction often arises due to a lack of communication, recognition, or conflicting goals.

Building a positive work culture where team members feel valued can reduce friction and improve collaboration.

Creating a Culture of Appreciation:

Regularly acknowledging contributions fosters trust and teamwork.

It encourages positive behavior and strengthens team bonds.

Why Other Options Are Incorrect:

Option A: Weekly feedback is useful but does not address the root causes of friction.

Option C: Nurturing competition can exacerbate conflicts and harm collaboration.

Option D: Anonymous feedback might provide insights but does not directly alleviate friction.

Defining Authentication:

Authentication is the process of verifying a user's identity to ensure they are who they claim to be.

This is commonly achieved through knowledge factors (passwords), possession factors (tokens), or biometric factors (fingerprints).

Why Other Options Are Incorrect:

Option A (Information secrecy): Focuses on protecting data, not identity confirmation.

Option B (Public key encryption): A method of encryption, not directly tied to user identity verification.

Option D (Authorization): Deals with granting access to resources after authentication.

Flash memory is a type of non-volatile rewritable memory that is compact and portable. It is commonly used in USB drives, SSDs, and memory cards. Unlike RAM, which loses data when power is off, flash memory retains stored information even without power.

Primary Elements of Information Infrastructure:

Business Continuity Plans (BCP): Ensure that critical business operations continue during and after a disruption.

Disaster Recovery Plans (DRP): Focus on restoring IT systems and data after a disaster.

Backup and Recovery Plans: Protect against data loss and enable data restoration after failures.

Why Other Options Are Incorrect:

Option B (Augmentation plans): Not a standard element of information infrastructure.

Option C (Authentication plans): Authentication is part of security protocols, not infrastructure support.

Definition of ERP Systems:

ERP integrates core business processes across various departments, such as finance, HR, procurement, and production.

It creates a centralized communication platform for cross-departmental collaboration and seamless data sharing.

Purpose of ERP:

Ensures real-time data visibility across the organization.

Promotes collaboration by eliminating data silos and enabling efficient workflows.

Incorrect Options Analysis:

B. Supply Chain Management (SCM): Focuses on logistics and supply chain optimization, not general collaboration.

C. Customer Relationship Management (CRM): Concentrates on customer interactions.

D. Electronic Data Interchange (EDI): Facilitates data sharing with external partners, not internal collaboration.
