Important WGU Information Technology Management QGC2 Exam Questions

Answer: C

Explanation:

Comprehensive and Detailed Explanation From Exact Extract:

The review conducted after deployment (often called a post-implementation review or post-deployment review) in the SDLC is intended to evaluate how successful the system is in the live environment and to identify opportunities for improvement. This review looks at:

Whether the system is delivering expected business benefits

How well it performs in real operational conditions

Feedback from users about usability and effectiveness

Issues encountered during and after rollout

Lessons learned for future projects

The emphasis is on continuous improvement and learning from the implementation experience to refine the current system and improve future system development efforts.

Option A (To plan the next phase of system upgrades) may be a result of the review, but planning upgrades is not the primary goal of the review itself.

Option B (To ensure users are properly trained) is part of deployment and change management activities, not the main goal of a post-deployment review.

Option D (To confirm the system meets original requirements) is largely addressed during system and acceptance testing before deployment.

Therefore, the goal of reviewing after deployment is to evaluate system success and identify improvements.

Answer: D

Explanation:

Scalability refers to the capability of a system, process, or facility to adapt and expand in response to increased demands, new product lines, or technology upgrades. In facility management, scalability ensures that layouts and systems can grow or be modified without requiring a complete redesign.

Option A: Operational redundancy ensures backup capacity, not adaptability.

Option B: Material requirements planning (MRP) focuses on inventory and materials, not facility layouts.

Option C: Sustainability focuses on environmental and long-term resource efficiency, not expansion capability.

Thus, the correct term is Scalability.

Answer: D

Explanation:

Prototyping in Software Development:

Prototyping involves creating a working model of the system to validate that it meets user and business requirements.

It is an iterative approach where users interact with the prototype and provide feedback for improvements.

Why Other Options Are Incorrect:

Option A (Waterfall): Follows a linear approach without iterative feedback.

Option B (RUP): A structured iterative approach but not focused solely on prototyping.

Option C (Iterative): While iterative development involves cycles, it does not specifically focus on building prototypes.

Answer: A

Explanation:

Comprehensive and Detailed Explanation From Exact Extract:

A Personal Area Network (PAN) is a network designed to connect individual devices over a very short range, typically within a few meters. It is commonly used to connect devices such as smartphones, tablets, laptops, wireless headsets, smartwatches, and other wearable or peripheral devices.

PANs often use technologies like:

Bluetooth

Near Field Communication (NFC)

Infrared (older devices)

The key characteristics of a PAN include:

Short physical range (typically a few meters around a person)

Personal use, focused on a single user's devices

Low power, wireless communication, suitable for mobile and wearable devices

Why the other options are incorrect:

B . Local area -- A Local Area Network (LAN) covers a larger area such as a home, office, or building and typically connects computers, printers, and servers, not just a single person's close-range devices.

C . Cellular -- A cellular network is provided by mobile carriers and covers large geographic areas, enabling mobile phone communication over many miles, not just within a short personal range.

D . Wide area -- A Wide Area Network (WAN) spans cities, countries, or even globally, connecting multiple LANs across long distances.

Therefore, the network type that connects smartphones and similar devices within a short range is a Personal Area Network (PAN).

Answer: A

Explanation:

Mercury, commonly found in older LCD displays, fluorescent backlights, and some batteries, is a toxic heavy metal that poses significant environmental and health hazards if electronic waste is not disposed of properly. It can contaminate soil and water supplies, harming both humans and wildlife.

Option B: Plastic is generally not toxic in the same way, though it contributes to waste.

Option C: Aluminum is recyclable and not considered highly hazardous.

Option D: Gold is valuable and recyclable, not an environmental hazard.

Therefore, the hazardous material in electronic devices is mercury in displays.
