WGU Introduction to IT 認定 Introduction-to-IT 試験問題 (Q23-Q28):

質問 # 23
What type of database uses parent-child relationships?

正解：C

解説：
Hierarchical databases use a parent-child relationship model. In this type of database, data is organized into a tree-like structure that implies a single-parent for each record. This model allows the representation of data in a hierarchy which is very much like a family tree. Each parent can have multiple children, but each child has only one parent (also known as a one-to-many relationship).
The hierarchical database model was one of the first database models, historically used with mainframe computers. In this model, records contain information about their groups of parent/child relationships, similar to a family tree. If we consider a database of employees,each department would be a parent node, and each employee within that department would be a child node of the department.
References: The concept of parent-child relationships in databases is well-established and discussed in various educational resources and forums. For example, Stack Overflow provides explanations of how these relationships work in practice12. Additionally, other resources like phoenixnap.com explain how these relationships are established in databases3.


質問 # 24
Which item is an input device?

正解：D

解説：
An input device is any hardware device that sends data to a computer, allowing you to interact with and control it. Input devices enable users to input information into the computer system. Let's break down the options:
*Flash Drive (A): A flash drive (also known as a USB drive or thumb drive) is a storage device, not an input device. It allows you to store and transfer data but does not directly input data into the computer.
*CD (B): A CD (compact disc) is also a storage medium, typically used for storing audio, video, or software files. Like a flash drive, it is not an input device.
*Scanner : A scanner is a classic example of an input device. It captures physical documents, images, or text and converts them into digital data that the computer can process. Scanners are commonly used for tasks like digitizing photos, creating PDFs, or scanning documents.
*Printer (D): A printer is an output device, not an input device. It produces hard copies (printed documents) based on digital data received from the computer.
In summary, the correct answer is C. Scanner, as it directly inputs data into the computer system.

質問 # 25
Which criterion is used to assess off-site storage solutions?

正解：C

解説：
Security is a primary criterion used to assess off-site storage solutions because stored backups must be protected against unauthorized access, theft, tampering, and data leakage. In Information Technology disaster recovery and business continuity planning, off-site backups often contain sensitive business records, customer information, and proprietary data. Therefore, evaluation typically includes physical security controls such as guarded facilities, access logs, surveillance, and secure transport, as well as logical security controls such as encryption, key management, and strong authentication. While redundancy and capacity can matter, security is often treated as a non-negotiable requirement because a backup that is exposed or altered can create major legal, financial, and operational risks. Device media refers to the type of storage, such as tape or disk, but it is usually considered a design choice rather than the main assessment criterion. Security also supports compliance requirements and helps ensure data integrity, so restored systems can be trusted. Therefore, the correct criterion for assessing off-site storage solutions is security.


質問 # 26
Which category of software allows other types of software to interface with the computer hardware?

正解：D

解説：
System software is the category that allows other software to interface with computer hardware. In Information Technology, system software includes the operating system, device drivers, and utility programs that manage hardware resources and provide a platform for applications. Applications such as word processors and web browsers do not communicate directly with hardware like the CPU, memory, storage devices, or printers. Instead, they use services provided by the operating system and drivers. The operating system manages processes, memory, and input and output operations, while device drivers translate general commands into device-specific instructions for hardware components. This layered design improves reliability and security by controlling access to hardware and standardizing how applications request resources. Productivity software refers to applications that help users perform tasks, and collaboration software supports communication and teamwork, but neither category provides the core hardware interface.
Shareware is a distribution and licensing model, not a hardware interface layer. Therefore, the correct category is system software.


質問 # 27
What is a function of a proxy server?

正解：C

解説：
A proxy server serves several essential functions in network communication:
1.Security and Privacy:
oA proxy server acts as a gateway between the user's device and the internet. When a user sends a request (e.
g., accessing a website), it first goes through the proxy server.
oThe proxy server hides the user's IP address, making it difficult for external entities to directly trace the user' s location or identity.
oBy acting as an intermediary, the proxy server provides an additional layer of security, protecting the internal network from potential threats and attacks.
2.Content Filtering and Access Control:
oOrganizations often use proxy servers to control internet access for their employees. The proxy can filter requests based on predefined rules.
oFor example, an organization might block access to certain websites (e.g., social media, gambling sites) or restrict access during work hours.
oContent filtering helps maintain productivity and prevent unauthorized access to inappropriate or harmful content.
3.Caching and Acceleration:
oProxy servers can cache frequently accessed web pages, images, and files. When a user requests the same content again, the proxy serves it from its cache.
oCaching reduces the load on the internet connection and speeds up access to commonly visited sites.
oIt also helps save bandwidth by minimizing redundant data transfers.
4.Load Balancing:
oIn large networks, multiple proxy servers can distribute incoming requests to different web servers. This load balancing ensures efficient utilization of resources.
oBy evenly distributing traffic, proxy servers prevent any single server from becoming overwhelmed.
5.Anonymity and Geolocation Bypass:
oSome users use proxy servers to hide their real IP addresses. This anonymity can be useful for privacy reasons or to bypass geolocation restrictions.
oFor example, a user in one country can use a proxy server located in another country to access region- restricted content.
