Question

When the physical location of the file changes in a distributed file system:

• A. File name also needs to be changed
• B. Host name of the file also needs to be changed
• C. Local name of the file also needs to be changed
• D. File name need not be changed

Hint:

A Distributed File System (DFS) provides location transparency, meaning files can be moved without changing their names.

Answer 1

The Correct Option is D

Step 1: Understanding Distributed File Systems (DFS)
- A distributed file system (DFS) enables access to files across multiple locations while maintaining a unified namespace.
- The file name remains the same even if the file is moved across different storage servers.

Step 2: Location Transparency
- DFS ensures location transparency, meaning users can access files using the same file name irrespective of their physical storage location.
- The file system internally handles mapping the file to its new location.
Step 3: Evaluating the Options
- (A) Incorrect: The file name does not need to change because DFS provides location transparency.
- (B) Incorrect: The host name does not need to change; DFS abstracts underlying storage details.
- (C) Incorrect: The local name remains unchanged within the unified namespace.
- (D) Correct: File names remain unchanged regardless of physical location changes in DFS.
