Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 46

Which storage protocol reduces file locks by using leasing?

Answer options

• A. SMB
• B. NFS 3
• C. NFS 4
• D. CIFS

Correct answer: C

Explanation

NFS 4 is the correct answer because it introduces a leasing mechanism that helps to reduce file locking conflicts by providing a way for clients to gain exclusive access to files. In contrast, SMB, NFS 3, and CIFS do not implement this leasing feature, making them less effective in minimizing file locks.
