Information-Technology-Management Exam Dumps - WGU Information Technology Management QGC2

Comprehensive and Detailed Explanation From Exact Extract:

A key benefit of manufacturing ERP systems is improved coordination of materials used in production. ERP integrates purchasing, inventory management, and production planning so that materials and components are:

Ordered at the right time

Delivered in the right quantities

Available at the correct locations for manufacturing activities

This integration reduces stockouts, excess inventory, and delays caused by missing parts, thereby making production more efficient and reliable. Improved material coordination supports smoother workflows on the production floor and better alignment between demand and supply.

Option A (Customized machine software) refers to specialized software for specific machines or equipment, which is not the primary benefit of a manufacturing ERP system.

Option B (Streamlined hiring processes) is a human resources function and would be associated with HR systems, not specifically manufacturing ERP.

Option C (Enhanced supplier marketing) relates more to marketing and promotion to suppliers, which is not a central benefit of manufacturing ERP.

Thus, the primary benefit listed that aligns with manufacturing ERP is improved material coordination.

Understanding Knowledge Factors:

Knowledge factors are something the user knows and are commonly used for authentication.

Examples include passwords, PINs, and security questions.

Why Other Options Are Incorrect:

Option A (ID card): This is a possession factor (something you have).

Option C (Security token): A security token is also a possession factor.

Option D (Fingerprint): This is a biometric factor (something you are).

Common Risks of Outsourcing Software Development:

One of the most significant risks is the potential for breaches of confidential information.

Outsourcing often involves sharing sensitive company data with third-party vendors, increasing the risk of data misuse or leaks.

Why This Risk is Common:

Outsourcing partners may not have the same level of security measures as the organization.

Compliance issues can arise if vendors do not adhere to industry regulations.

Incorrect Options Analysis:

B. High cost of developers' salaries: Outsourcing is generally cost-effective compared to in-house salaries.

C. Lack of flexibility: Many outsourcing providers are designed to adapt to changes.

D. Short-term contracts: While challenging, these are manageable compared to confidentiality risks.

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).

The Development phase of the SDLC is where programmers write, compile, and build code to create the actual software system. This is based on the specifications created in the design phase.

Option A (Deployment): Involves moving the system to production.

Option B (Testing): Focuses on defect detection and validation.

Option D (Design): Defines technical specifications but does not involve coding.

Thus, the coding occurs in the Development phase.

The Construction phase of the Rational Unified Process (RUP) is where software requirements are translated into working code. During this phase, developers build the system by coding, integrating, and testing components based on the validated architecture.

Option A (Elaboration): Focuses on refining requirements and validating architecture.

Option B (Inception): Defines the scope, objectives, and business case.

Option D (Transition): Involves system deployment and user acceptance testing.

Thus, the correct phase is Construction.

In modern IT management, the ITIL framework is not prescriptive or rigid; instead, it provides flexible and adaptable guidelines that organizations can tailor to their size, structure, and needs. ITIL is designed to enhance IT service quality, efficiency, and alignment with business goals. It can be implemented in organizations of any size, not just large enterprises, and it does not replace other frameworks but can be used alongside them.

Option A: Incorrect, ITIL does not dictate rigid step-by-step processes; it offers adaptable practices.

Option B: Incorrect, ITIL complements, not replaces, other frameworks (like COBIT, Agile, or DevOps).

Option D: Incorrect, ITIL applies to both small and large organizations.

Therefore, ITIL’s role is to provide adaptable guidelines to enhance IT services.

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.
