質問 # 55
Which file system is commonly used in Windows and supports file permissions?
正解：D
解説：
Windows commonly uses the NTFS (New Technology File System) for internal drives and many external drives because it supports advanced features required for modern operating systems. One of the most important features is support forfile and folder permissionsvia Access Control Lists (ACLs). Permissions enable the OS to enforce security policies by controlling which users and groups can read, write, execute, modify, or delete specific resources. This is fundamental to multi-user security and is a standard topic in operating systems and security textbooks.
FAT32 is an older file system designed for simplicity and broad compatibility. It does not provide the same fine-grained permission model as NTFS, which is why it is often used for removable media where cross- platform compatibility matters more than access control. HFS+ is historically associated with Apple's macOS systems, and EXT4 is widely used on Linux. While these file systems have their own permission and feature models, they are not the common Windows default for permission-managed storage in typical Windows deployments.
NTFS also supports journaling (improving reliability after crashes), large file sizes, quotas, compression, and encryption features (through Windows facilities). In enterprise environments, NTFS permissions integrate with Windows authentication and directory services, enabling centralized user management. Therefore, for Windows systems requiring file permissions, NTFS is the correct answer.
質問 # 56
What is the only content that will display if the List folder contents permission is not enabled for a particular folder in Windows 11?
正解：A
解説：
In Windows file security (NTFS permissions), "List folder contents" controls whether a user cansee the names of files and subfoldersinside a folder. If a user does not have permission to list a folder, Windows prevents directory enumeration: the user cannot browse the folder and view what is inside. (2BrightSparks) This is a key concept in access control: it separates "being able to traverse to a location" from "being able to see what is stored there." When "List folder contents" is not enabled, the user typically cannot view the list of files regardless of whether individual files might have separate permissions. In standard user-facing behavior, what remains visible in the folder's properties and metadata is limited; among the choices given, the only item that is reliably a folder-level metadata attribute (and not a listing of contents) is the folder'screation date. The
"author" is not a universal, reliably displayed NTFS folder property, and options C and D talk about files (contents), which cannot be listed without the list permission. (2BrightSparks) This reflects a broader textbook principle: operating systems enforce access control both on objects (files/folders) and on operations (read data, write data, list directory). Removing the list operation blocks visibility of contents, even if other permissions exist elsewhere.
質問 # 57
print(20 # 5)
What will the output be of this line?
正解：B
解説：
In Python, the # character begins acomment. Everything from # to the end of the line is ignored by the interpreter and is not executed. Therefore, the line # print(20 # 5) producesno outputbecause it is a comment, not an executable statement. This is a standard concept in programming language textbooks: comments are for humans, not for the machine, and they are used to document code, explain intent, temporarily disable statements during debugging, or leave notes about assumptions and design choices.
Even though the line contains an unusual symbol #, it does not matter here, because the interpreter never tries to parse the commented text. If the # were removed, then Python would attempt to parse print(20 # 5), and since # is not a valid Python operator, that would indeed trigger a syntax error. But with the leading #, the entire line is inert.
Option A is incorrect because nothing is evaluated. Option C is incorrect because comments are not printed; they remain only in the source code. Option D is incorrect for the commented version of the line, since Python does not check comment contents for syntax. Thus, the correct result is no output.
質問 # 58
What is the layer of programming between the operating system and the hardware that allows the operating system to interact with it in a more independent and generalized manner?
正解：A
解説：
TheHardware Abstraction Layer (HAL)is a software layer that sits between the operating system kernel and the physical hardware. Its purpose is to hide hardware-specific details behind a consistent interface, allowing the OS to be more portable and easier to maintain across different hardware platforms. Textbooks explain that without abstraction, the OS would need extensive device- and architecture-specific code scattered throughout the kernel, making updates and cross-platform support far more difficult.
The HAL typically provides standardized functions for interacting with low-level components such as interrupts, timers, memory mapping, and device I/O. With a HAL, the OS can call general routines (for example, to configure an interrupt controller) while the HAL handles the platform-specific implementation.
This supports a key systems principle: separate policy (what the OS wants to do) from mechanism (how hardware accomplishes it).
The other options are not correct. A boot loader runs at startup to load the operating system into memory; it is not the general interface layer during normal operation. The task scheduler is a kernel subsystem that manages CPU time among processes, not a hardware-independence layer. The file system layer manages storage organization and access semantics; it is not the general abstraction for all hardware interactions.
Therefore, the programming layer that enables generalized OS interaction with hardware is the hardware abstraction layer.
質問 # 59
Which process is designed to establish the identity of the user such as with a username and password?
正解：B
解説：
Authenticationis the security process of proving or establishing a user's identity. In textbook terminology, authentication answers the question: "Who are you?" Common authentication factors include something you know (password, PIN), something you have (smart card, hardware token), and something you are (biometrics). Username and password is the classic "something you know" mechanism, where the username identifies the account and the password serves as a secret used to validate that the user is the rightful owner of that account.
Authentication is distinct fromauthorization, which determines what an authenticated user is allowed to do (permissions, roles). It is also distinct from registration, which is the administrative act of creating an account or enrolling a user in a system. "Verification" is a general term that can appear in many contexts, but in security frameworks the precise term for identity establishment is authentication. "Certification" usually refers to issuing or validating credentials such as digital certificates (PKI) or professional certifications, not the act of logging in with a password.
Textbooks emphasize that authentication should be strengthened with practices like hashing and salting passwords, multi-factor authentication (MFA), lockout policies, and secure transport (e.g., TLS) to prevent credential theft. The core concept remains: the process that establishes identity using credentials like a username and password is authentication.
