質問 # 55
What is the arrangement of network devices in a mesh topology?
正解：D
解説：
In a mesh topology, every device is connected to every other device. In Information Technology networking fundamentals, a full mesh topology provides multiple direct paths between nodes, which improves redundancy and fault tolerance. If one connection fails, data can often be rerouted through other links, reducing the chance of total network disruption. This makes mesh designs valuable for mission-critical environments where high availability is required. However, the number of connections grows quickly as devices increase, which raises cost, complexity, and management overhead. The other options describe different topologies: a star topology connects all devices to a central device such as a switch, a bus topology connects devices to a single shared communication line, and a ring topology connects each device to exactly two others, forming a loop. Because the defining feature of a mesh is the extensive interconnection among devices, the correct description is that every device is connected to every other device. Therefore, the correct answer is option C.
質問 # 56
A company needs a database in which data is stored in a plain text document and is separated by delimiters, such as commas. Which type of database is needed?
正解：C
解説：
A flat-file database is designed to store data in a single, plain text file where values are arranged in records and fields, often separated by delimiters such as commas, tabs, or semicolons. A common example is a CSV file, which stores each record on its own line and separates fields with commas. In Information Technology fundamentals, flat-file storage is frequently introduced as a simple way to maintain structured data without requiring a complex database management system. Flat-file databases work well for smaller datasets, simple lists, data exports, and situations where relationships between multiple tables are not required. However, because everything is typically stored in one file, flat-file systems can become inefficient and error-prone when data grows large or when updates must maintain consistency across repeated values. Hierarchical databases organize data in parent-child trees, distributed databases store data across multiple machines, and cloud databases focus on hosting and access models. For delimiter-separated plain text storage, the correct type is a flat-file database.
質問 # 57
Which component comes in two varieties, one that mechanically writes binary data onto spinning magnetic disks and one that writes data with no mechanical parts?
正解：B
解説：
The hard drive category includes two common storage varieties: traditional hard disk drives and solid-state drives. A hard disk drive stores binary data magnetically on spinning platters and uses mechanical parts such as a rotating motor and moving read and write heads. In contrast, a solid-state drive stores data using non- volatile flash memory with no moving mechanical components. In Information Technology hardware concepts, both serve the same role as secondary storage, meaning they store files, applications, and the operating system persistently even when power is off. Hard disk drives are often lower cost per gigabyte and are common in large-capacity storage, while solid-state drives provide faster access times, improved performance, and better resistance to physical shock. The motherboard is the main circuit board, the system clock provides timing pulses, and an expansion bus is a communication pathway for add-on devices. Since the question describes mechanical and non-mechanical storage types, the correct component is the hard drive.
質問 # 58
Which IT department goal would support business goals?
正解：B
解説：
IT goals directly support business goals when they enable or improve the core activities that generate revenue or growth. Here's why this option stands out:
*E-commerce Expansion: An online shopping cart directly facilitates sales, expanding the company's reach and providing customers with a convenient way to purchase products. This aligns with common business goals of increasing sales and market share.
質問 # 59
What type of a system requirement involves preventing unauthorized access to data?
正解：A
解説：
*Unauthorized access refers to gaining entry or access to a system, physical or electronic, without the permission of the owner or administrator.
*Security is the type of system requirement that involves preventing unauthorized access to data.
*Security measures include:
oAuthentication: Verifying user identity.
oEncryption: Protecting data from unauthorized viewing.
oAccess controls: Limiting who can access specific resources.
oFirewalls: Filtering network traffic.
*Ensuring security helps safeguard sensitive information and maintain data integrity.
