Free Mock Test - Operating System : File Management (Test 2)

File Management is one of the core functions of an Operating System. It is responsible for creating, organizing, storing, retrieving, and managing files on a computer system. Through file management, users can easily access their data, maintain structure, and ensure efficient use of storage devices.
File Management is a frequently asked topic in various academic and competitive exams such as BCA, B.Tech, MCA, and government job exams.The Operating System: File Management online test by teachexam is an excellent resource for students who want to strengthen their concepts and prepare effectively for exams. Regular practice through such tests improves knowledge retention, boosts confidence, and ensures better academic performance.

Total Questions : 20

Timer : sec

Question : Which of the following problems is NOT directly associated with single-level directories?

Naming problem

Grouping problem

Security limitation

Path traversal complexity

none

Question : Which scenario best justifies the use of a single-level directory?

Large enterprise system with multiple users

Distributed system with network storage

Small system with limited number of files

Cloud-based storage system

none

Question : Why does file searching become inefficient in a single-level directory when the number of files increases?

Files are encrypted

No indexing mechanism is used

All files are stored in one directory without categorization

Files are stored in different partitions

none

Question : Which of the following is the major limitation of a single-level directory in a multi-user system?

Complex implementation

Low memory usage

Naming conflicts among users

Slow file creation

none

Question : In a single-level directory structure, which of the following is a mandatory constraint?

Files must be grouped into subdirectories

Each file must have a unique name

Files must have different extensions

Each user must have a separate directory

none

Question : Why is searching faster in a two-level directory compared to a single-level directory?

Files are stored sequentially

Only one user’s directory needs to be searched

Files are indexed globally

Uses hashing techniques

none

Question : Which of the following is a major disadvantage of a two-level directory?

File name conflicts among users

Complex searching mechanism

Lack of file sharing between users

High memory consumption

none

Question : In a two-level directory system, the pathname of a file is typically:

/root/file

/user-name/file-name

/directory/file

/file/user

none

Question : Which of the following is NOT a feature of a two-level directory system?

Same file names allowed for different users

Efficient searching within user directory

Ability to create subdirectories inside UFD

User-level file isolation

none

Question : In a two-level directory structure, the Master File Directory (MFD) primarily stores:

All files of all users

File contents

Entries of user directories

Only system files

none

Question : Which of the following correctly describes access control in a tree-structured directory?

All users have equal access to all directories

Only root can read files

Permissions like read, write, execute are assigned to users

No permission mechanism exists

none

Question : In a tree-structured directory, the current working directory (CWD) is used to:

Delete root directory

Define relative paths

Restrict user access

Store file permissions

none

Question : Which limitation still exists in a tree-structured directory system?

No file creation allowed

No support for multiple users

Difficulty in sharing files across directories

No support for path names

none

Question : Which feature of tree-structured directories improves search efficiency?

Linear list storage

Flat file organization

Hierarchical grouping of files

Random file allocation

none

Question : In a tree-structured directory, which of the following best describes an absolute path?

Path starting from current directory

Path starting from root directory

Path that contains only file name

Path that avoids directory traversal

none

Question : Which statement best differentiates acyclic graph directories from tree-structured directories?

Tree allows sharing, acyclic does not

Acyclic allows multiple paths to same file, tree does not

Tree is more flexible than acyclic

Acyclic does not use links

none

Question : Which of the following problems is associated with acyclic-graph directory structures?

Lack of file sharing

Duplicate file storage

Multiple path names (aliasing problem)

No support for links

none

Question : In case of a hard link in an acyclic graph directory, when is the actual file deleted?

When any one link is deleted

When the original file is deleted

When all references (links) are removed

Immediately after unlink operation

none

Question : What is the primary reason for restricting cycles in an acyclic-graph directory?

To reduce memory usage

To simplify file naming

To prevent infinite traversal loops

To avoid file duplication

none

Question : In an acyclic-graph directory structure, which of the following statements is correct?

A file can have only one parent directory

A file can have multiple parent directories through links

Cycles are allowed but controlled

Files are always duplicated when shared

none
