Network File System (NFS) Quiz

What is the main advantage of a distributed file system?

• Allows easy sharing of data among clients

• Allows easy sharing of data among servers

• Provides decentralized administration

• Provides security for client machines

What components are involved in the architecture of a distributed file system?

• Client-side file system and physical disk

• Client-side file system and server-side database

• Server-side file system and physical disk

• Client-side file system and server-side file system

Which company developed the Network File System (NFS)?

• Microsoft

• IBM

• Apple

• Sun Microsystems

Why is the goal of simple and fast server crash recovery important in multi-client and single-server based network architectures?

• To prevent all clients from being unserviced in case of server crash

• To prevent data corruption

• To ensure data encryption

• To prevent unauthorized access

What type of protocol does NFS implement?

• Encrypted protocol

• Stateful protocol

• Stateless protocol

• Secure protocol

What does NFS use to uniquely identify a file or directory that the current operation is being performed upon?

• File Identifier

• File ID

• File Pointer

• Volume Identifier

What is the purpose of the volume identifier in NFS?

• To identify the file being accessed by the client

• To identify the file system or partition on the server

• To identify the server machine

• To identify the client machine

Why does NFS use file handles to identify files or directories?

• To reduce network traffic

• To improve file access speed

• To uniquely identify files or directories

• To provide additional security

What does a stateless protocol mean in the context of NFS?

• The server is unaware of what the clients are doing

• The server stores state information for each client

• The server requires clients to maintain state information

• The server maintains a constant state with the clients

What happens if a server crash occurs in a stateless protocol like NFS?

• The clients need to retry their requests

• The server automatically recovers and resumes service

• The clients lose access to the server permanently

• The clients are automatically disconnected
