Global population growth directly correlates with an increase in the potential user base for digital products and services. This expanding market creates a significant demand for more data, connectivity, and processing power. Consequently, IT leaders are compelled to strategically plan for and support the rapid expansion of digital infrastructures—including data centers, cloud services, and network capabilities—to meet this rising demand, ensure service quality, and maintain a competitive edge.

B. By restricting access to conserve existing resources

Restricting access is a counterproductive strategy that fails to meet market demand and would lead to loss of business and relevance.

C. By delaying upgrades until population trends stabilize

Population growth is a long-term, continuous trend; delaying necessary upgrades would result in overwhelmed, obsolete, and insecure systems.

D. By focusing on routine system upkeep instead of expanding

While upkeep is essential, ignoring expansion in a growth environment would make systems incapable of handling the increased load, leading to performance failures.

The Information Technology Infrastructure Library (ITIL) is a globally recognized framework for IT Service Management (ITSM). Its fundamental purpose is to ensure that an organization's IT services are aligned with its business needs and objectives. ITIL provides a set of detailed practices and processes for creating, delivering, and supporting IT services throughout their lifecycle. By adopting ITIL, organizations can improve service quality, optimize costs, and ensure that IT investments deliver tangible value to the business, effectively bridging the gap between IT operations and business strategy.

A. This describes software development lifecycle (SDLC) methodologies like Agile or Scrum, which focus on building software, not managing the resulting IT services.

C. ITIL is a management framework of best practices and processes; it is not a programming or coding language used by developers.

D. This pertains to manufacturing and quality management standards, such as those from the International Organization for Standardization (ISO), not IT service delivery.

The company's strategic shift from a product-centric to a customer-centric model focuses on increasing customer lifetime value. This requires a deep understanding of individual customer needs, preferences, and purchase history. Customer Relationship Management (CRM) software is specifically designed for this purpose. It gathers customer data from various touchpoints, consolidates it, and provides analytical tools to identify opportunities for cross-selling and up-selling. By analyzing this information, the company can tailor marketing campaigns to sell "one customer as many products as possible," thereby enhancing customer loyalty and profitability.

A. Distribution management (DM): This software focuses on the logistics of moving finished products from the manufacturer to the end-user, not on analyzing customer data for marketing purposes.

C. Supply chain management (SCM): SCM software manages the entire flow of goods, from raw materials to final delivery. Its primary goal is supply chain efficiency, not individual customer marketing.

D. Operations management (OM): This is a broad field concerned with managing the processes that produce goods and services. It is not a specific type of software for customer data analysis.

An IT Strategy Board, often called an IT Steering Committee, is a high-level governance body. Its primary function is to ensure that the organization's IT strategy is aligned with its overall business strategy. This involves two key activities: first, continuously scanning the technological horizon to identify and evaluate emerging technologies and trends (C). Second, based on this analysis and an understanding of business needs, the board recommends strategic actions and investments in technology that will create value, drive innovation, and provide a competitive advantage for the organization (D). The board's focus is strategic and forward-looking, not operational.

A. Reporting IT issues and implementing solutions are operational responsibilities of the IT department and its management, not the function of a high-level strategic board.

B. While the board has financial oversight, recognizing budget overages is a tactical project or financial management control function, not a primary strategic purpose of the board.

E. Overseeing hiring is a function of Human Resources and departmental line management. The board is concerned with strategic capabilities, not the tactical process of hiring individuals.

A data model is an abstract, logical representation that organizes data elements and defines the relationships between them. A key function of data models, particularly conceptual and logical models like the Entity-Relationship (E-R) model, is to use graphical diagrams. These diagrams employ standardized symbols (e.g., boxes for entities, diamonds for relationships, ovals for attributes) to provide a clear, visual illustration of the database structure. This graphical nature makes complex data relationships understandable to various stakeholders, facilitating database design and communication.

A. Integration: This is a process of combining data from different sources into a unified view, not a graphical structure itself.

B. Structured query language: This is a text-based programming language used for querying and managing data in a database, not a graphical representation.

D. Relational database model: This is a specific type of data model based on tables (relations). While it can be visualized, "data model" is the broader term for the structure that uses graphics.

Creating a culture of showing appreciation is a proactive leadership strategy to improve team dynamics. It fosters psychological safety, where team members feel valued and respected. This positive reinforcement strengthens interpersonal relationships, builds trust, and improves morale. By focusing on positive contributions, a director can shift the team's focus from conflict to collaboration, directly addressing the root causes of friction and creating a more cohesive and productive environment. This approach encourages open communication and mutual support, which are essential for high-performing software development teams.

A. Ask each team member to provide weekly feedback via email

This method is impersonal and lacks the nuance of direct communication, potentially leading to misinterpretations and escalating conflicts.

C. Nurture competition among team members

Competition fosters a win-lose dynamic, which is known to increase tension, resentment, and destructive conflict, directly undermining team cohesion.

D. Provide a public forum for anonymous feedback

A public and anonymous forum can easily become toxic, encouraging blame and personal attacks without accountability, thereby worsening team friction.

The bullwhip effect is a supply chain phenomenon describing how small fluctuations in demand at the retail level can cause progressively larger fluctuations in demand at the wholesale, distributor, manufacturer, and raw material supplier levels. This amplification of demand variability is primarily caused by a lack of visibility and poor communication between supply chain partners. Each partner makes forecasts based on the orders they receive, not the end-customer demand, leading them to carry "safety stock" or excess inventory to compensate for the uncertainty. This results in stockpiling and inefficiency throughout the supply chain.

B. This describes a mitigation strategy for the bullwhip effect, often called supply chain visibility, which is the opposite of the problem itself.

C. This defines the "maker movement" or "prosumerism," a cultural trend unrelated to supply chain demand amplification.

D. This is the definition of the "network effect" (or Metcalfe's Law), where a service's value increases as more people use it.

Green computing focuses on minimizing the environmental impact of information technology. A core principle of this practice is following the waste management hierarchy: Reduce, Reuse, Recycle. Extending the life of devices through reuse and refurbishment directly addresses the "Reuse" principle. This strategy is environmentally superior to recycling because it conserves the significant energy and resources embedded in the manufacturing of the original device and delays the generation of electronic waste (e-waste). By keeping equipment in service longer, organizations reduce the need for new production and minimize their overall environmental footprint.

B. Prioritizing high performance often leads to greater energy consumption, which directly conflicts with the green computing goal of energy efficiency.

C. Choosing hardware that is merely economical often overlooks energy efficiency and durability, potentially increasing long-term energy costs and creating e-waste sooner.

D. Recycling hardware before its end of life is a wasteful practice that contradicts the waste hierarchy, which prioritizes reuse over recycling for functional equipment.

Read-only memory (ROM) is a type of non-volatile memory, meaning it retains its stored information even after power is removed. It is considered a minor component as it is typically a small, integrated chip on the motherboard that holds essential system firmware, such as the BIOS or UEFI. This firmware is crucial for the computer's startup process (booting) but has a limited and specific function compared to major components like primary storage drives or the CPU.

A. Arithmetic-logic unit (ALU): The ALU is a core part of the CPU that performs calculations and logical operations; it is not a memory storage component.

C. Random-access memory (RAM): RAM is the main system memory, but it is volatile, meaning it loses all stored data when the computer is powered off.

D. Solid-state drive (SSD): While an SSD holds non-volatile memory, it is classified as a major secondary storage device, not a "minor component."

Modern Enterprise Resource Planning (ERP) systems, particularly those delivered via a Software-as-a-Service (SaaS) or cloud model, are designed to be accessible to small businesses. The primary benefits are a lower total cost of ownership and simplified implementation. Instead of a large, upfront capital expenditure for hardware and software licenses, small businesses can pay a predictable monthly subscription fee. Vendors also provide pre-configured templates and handle backend maintenance, which significantly simplifies the setup process and reduces the need for a large, specialized IT staff.

A. Minimal IT infrastructure: While cloud-based ERPs do require minimal on-site IT infrastructure, this is a contributing factor to the broader benefits of low cost and simple setup, making option D a more comprehensive and primary answer.

B. Offline processing only: This is fundamentally incorrect. The core value of an ERP system is its ability to provide real-time, integrated data processing across all business functions, which requires online connectivity.

C. Customizable business modules: Extensive customization is a feature more suited to large enterprises with unique processes and deep pockets. For small businesses, high customization is often prohibitively expensive and complex, not a primary benefit.
