Using an operating system and file management

Correct answer: C. Subfolders or files can receive permissions from the parent folder

Explanation: Permission inheritance is an access-control concept in which permissions assigned to a parent folder can flow down to its child subfolders and files. Therefore, option C is correct. It does not determine a file’s name or size, and it does not delete files. Administrators should review inherited permissions carefully because a broad parent permission may unintentionally grant access to sensitive items.

Correct answer: D. The owner may receive special authority to control permissions

Explanation: File ownership identifies the account or user responsible for a file and may give that owner special authority to manage its permissions, depending on the operating system. Option D is correct. Ownership does not compress a file, change its format, or hide it automatically. Ownership and permissions are related but different: permissions define allowed actions, while ownership identifies who can administer or alter access settings.

Correct answer: A. Make a file system accessible within the directory structure

Explanation: Mounting is the operating-system operation that makes a storage device or file system available at a chosen location in the directory tree, called a mount point. Option A is correct because users can access the stored files through that location after mounting. Mounting is not deletion, a physical monitor action, or printer maintenance; those distractors describe unrelated operations.

Correct answer: B. To complete pending writes and prevent file-system inconsistency

Explanation: Unmounting tells the operating system to stop using the mounted file system and to complete or flush pending write operations. This reduces the chance that directory information or file contents remain only partly updated. Therefore, option B is correct. Unmounting does not increase capacity, rename files, or shut down the CPU. Removing storage without unmounting can cause data loss or file-system corruption.

Correct answer: C. Limit storage used by a user or group

Explanation: A disk quota sets a maximum amount of storage that a particular user or group may consume on a system. Option C is correct because quotas help prevent one account from filling a shared disk and leaving no space for others. A quota does not grant administrator rights, move every file into one folder, or hide file extensions. It is a resource-management control, not a file-format feature.

Correct answer: D. To detect and repair logical file-system errors

Explanation: A file-system checking tool examines the logical structure of a storage system, including directories, file records, and allocation information. It can report or repair inconsistencies caused by errors, improper shutdowns, or damaged metadata. Therefore, option D is correct. It does not change monitor resolution, translate language, or create printer drivers. Important data should be backed up before repairs are attempted.

Correct answer: A. Prevent all copies from being lost together in a fire, theft, or local disaster

Explanation: An off-site backup protects data from incidents that affect the main location, such as fire, theft, flooding, or another local disaster. If every copy is stored in the same place, one event can destroy them all. Therefore, option A is correct. Changing extensions, speeding up the operating system, and increasing monitor brightness are unrelated to backup resilience. Backups should also be tested by restoring sample data.

Correct answer: A. The process is waiting to receive processor time

Explanation: In the ready state, a process has all resources needed to run except immediate access to the processor. It is placed in the ready queue and waits for the scheduler to allocate processor time. Therefore, option A is correct. A terminated process is no longer running, while waiting or blocked describes a process waiting for an input or event rather than merely waiting for the processor.

Correct answer: B. When it must wait for an input or event

Explanation: A process enters the waiting, or blocked, state when it cannot continue until an external condition is satisfied, such as input arriving, a disk operation completing, or a required event occurring. Option B is correct. Renaming a process, switching off a monitor, or compressing a file does not by itself define this state. After the event occurs, the process usually returns to the ready state.

Correct answer: C. The processor state of the current process

Explanation: During a context switch, the operating system saves the current process’s execution context, such as processor registers, the program counter, and relevant scheduling information. It then loads the saved context of another process so multitasking can continue. Therefore, option C is correct. A file name, monitor brightness, or printer ink level is not the process context required to resume execution accurately.
