CompTIA Network+ (N10-007) — Question 246

The backup server connects to a NAS device using block-level storage over Ethernet. The performance is very slow, however, and the network technician suspects the performance issues are network related. Which of the following should the technician do to improve performance?

Answer options

• A. Utilize UDP to eliminate packet overhead
• B. Turn off MDIX settings on the NAS and server switchports
• C. Enable jumbo frames on the NAS and server
• D. Encapsulate the storage traffic in a GRE tunnel

Correct answer: C

Explanation

Enabling jumbo frames allows for larger packet sizes, which can significantly reduce CPU load and improve throughput in a network, particularly in storage environments. The other options do not directly address the performance limitations in this specific context, as using UDP may introduce reliability issues, turning off MDIX may cause connectivity problems, and encapsulating traffic in a GRE tunnel adds unnecessary overhead.
