NAS type storage includes CIFS and NFS file systems. Which of the following descriptions about CIFS and NFS are correct? (Multiple choice)

Question

Options

• ACIFS preserves file format characteristics
• BNFS requires no additional software
• CCIFS cannot perform error recovery
• DCIFS is based on the network and requires high reliability

• A
  15% (10)
• B
  6% (4)
• C
  79% (53)

Explanation

C is correct because CIFS has poor error recovery - when a network interruption occurs, a CIFS session typically cannot gracefully resume, forcing clients to reconnect and potentially losing in-progress operations. D is correct because CIFS transmits data over a network using TCP/IP and is highly sensitive to network conditions; unstable or high-latency connections directly degrade performance and reliability.

Why A is wrong: It is NFS, not CIFS, that is better known for preserving Unix/Linux file format characteristics (permissions, ownership, etc.) transparently. CIFS maps Windows-style file attributes and does not inherently preserve cross-platform file format characteristics.

Why B is wrong: NFS absolutely requires additional software - both the server and client systems need NFS daemons/services installed and configured. Client machines must mount NFS shares using NFS client software before they can access the storage.

Memory tip: Think of CIFS as "Chatty and Fragile over Networks" - it's verbose, network-dependent (D), and drops the ball when the connection hiccups (C). NFS, by contrast, is the Unix workhorse that needs setup on both ends (ruling out B) and natively understands file system attributes (ruling out A as a CIFS trait).
