問題 #17
Which principle can be used to implement an algorithm to calculate factorial or Fibonacci sequence?
答案：B
解題說明：
Factorial and Fibonacci are classic examples used to teachrecursion, a technique where a function solves a problem by calling itself on smaller subproblems. The key requirement for recursion is (1) abase casethat stops further calls and (2) arecursive casethat reduces the problem size. For factorial, the definition is (n! = n
\times (n-1)!) with base case (0! = 1) (or (1! = 1)). For Fibonacci, (F(n) = F(n-1) + F(n-2)) with base cases (F (0)=0) and (F(1)=1). These mathematical definitions map directly into recursive code, which is why textbooks frequently introduce recursion using these sequences.
While factorial and Fibonacci can also be computed iteratively, the question asks for the principle that can be used to implement such algorithms, and recursion is the canonical textbook answer. Recursion also connects to important CS topics: call stacks, activation records, and divide-and-conquer problem solving.
Option A ("procedural programming") and option D ("object-oriented programming") are broader paradigms rather than the specific technique used in the classic implementations. Option B ("iterative programming") is a valid alternative approach, but the standard instructional principle highlighted for these particular examples is recursion. Textbooks also note that naive recursive Fibonacci is inefficient (exponential time) unless optimized with memoization or converted to an iterative or dynamic programming approach.
問題 #18
Which Python command can be used to display the results of calculations?
答案：A
解題說明：
In Python, the standard way to display output to the console is the built-in function print(). When a program performs calculations-such as arithmetic expressions, function results, or computed statistics-print() can be used to show those results to the user. For example, print(2 + 3) displays 5, and print(total / count) displays the computed average. Textbooks introduce print() early because it supports interactive learning, debugging, and communicating program behavior.
print() can display one or multiple items separated by commas, automatically converting them to string form.
It also supports formatting via f-strings (e.g., print(f"Sum = {s}")) and optional parameters like sep and end to control output formatting. This makes it versatile for reporting calculated values, intermediate steps in algorithms, and final program outputs.
The other options are not standard Python built-ins for output. compute(), result(), and solve() are not universally defined commands in Python; they might exist as user-defined functions or in specific libraries, but they are not the general command taught in textbooks for displaying results. Python follows a clear separation: expressions compute values; print() displays them.
Therefore, the correct answer is print(), as it is the primary mechanism for producing human-readable output from calculations in typical Python programs and coursework.
問題 #19
Which type of files are meant to be inaccessible to standard users, but can be critical in terms of functionality?
答案：B
解題說明：
Operating systems contain many files that are essential for booting, hardware support, security enforcement, and core services. These are generally referred to assystem files. Textbooks explain that system files are often protected by permissions and special attributes because accidental modification or deletion could destabilize the OS, break device drivers, prevent applications from running, or even stop the machine from booting.
Therefore, standard (non-administrator) users are typically restricted from accessing or altering them, and the OS may hide them by default to reduce the risk of user error.
Examples include kernel-related components, shared libraries, driver files, configuration databases, and critical service executables. Modern OS designs enforce protection through user accounts, access control lists, and privilege separation. This ensures only trusted processes and administrators can change system-critical components.
Log files record events and are sometimes protected, but many logs are readable by users or administrators depending on policy; they are not necessarily "meant to be inaccessible" in the same strict sense. Backup files are important for recovery but are not inherently system-critical for day-to-day operation, and their accessibility depends on organizational policy. "Extension files" is not a standard category; file extensions describe formats rather than a protected functional class.
Thus, the files intended to be inaccessible to standard users yet critical for functionality are system files, reflecting core OS security principles such as least privilege and integrity protection.
問題 #20
Which Windows 11 tool enables a user to manually add a Bluetooth device if it does not automatically configure when first connected?
答案：A
解題說明：
When a Bluetooth device does not configure automatically, the underlying issue is often driver discovery, device enumeration, or the Bluetooth adapter's state. In Windows, the tool traditionally associated with manually managing hardware devices and their drivers isDevice Manager. It lets a user view hardware categories (including Bluetooth adapters), enable or disable devices, update drivers, uninstall and rescan, and address "unknown device" situations. These actions are core to manual configuration because they influence whether Windows can properly recognize and communicate with a Bluetooth device.
Windows 11 pairing itself is typically initiated from the Settings app under Bluetooth and devices, where a user chooses "Add device" to pair a new accessory. (Microsoft Support) However, among the options provided, only Device Manager is a hardware-configuration tool that can resolve situations where automatic configuration fails due to driver or adapter problems. Network-related tools do not handle local device drivers, Task Scheduler automates tasks rather than adding devices, and Windows Defender is focused on security and malware protection rather than device setup.
From a systems perspective, this reflects a key operating-systems concept: successful device use requires both discovery/pairing and a correctly installed driver stack. Device Manager is the standard interface for the driver and device side of that equation, which is why it is the best match to "manually add or configure" hardware in the given choices.
問題 #21
Which is the most powerful command line interface on Windows systems?
答案：A
解題說明：
On Windows,PowerShellis generally regarded as the most powerful command-line environment because it is both a shell and a scripting language designed for system administration and automation. Traditional Command Promptfocuses on running console commands and batch files with plain-text input and output.
PowerShell, by contrast, uses an object-oriented pipeline: commands (calledcmdlets) output structured objects rather than raw text. This enables more reliable scripting and data manipulation, since you can filter, sort, and transform results without fragile text parsing.
Textbooks covering operating systems and administration emphasize automation and management at scale.
PowerShell integrates tightly with Windows management technologies, such as WMI/CIM, the registry, services, event logs, and Active Directory environments. It also supports remote management, scripting modules, robust error handling, and modern security features. This makes it particularly suitable for tasks like provisioning users, configuring machines, auditing systems, and orchestrating deployments.
The other options are not command-line interfaces in the same sense. Task Manager is a GUI tool for viewing processes and performance. Control Panel is also GUI-based for system configuration. Command Prompt is a command line interface, but it is less capable for complex administration compared to PowerShell's scripting and object pipeline.
Therefore, from a computer science and systems perspective, PowerShell is the most powerful Windows CLI environment among the choices.
