VMware NSX-T Data Center (VCP-NV 2019) — Question 54

What is VMware's recommendation for the minimum MTU requirements when planning a NSX-T Data Center deployment?

Answer options

• A. MTU should be set to 1550 or less across the data center network including inter-data center connections.
• B. MTU should be set to 1500 or less only on inter-data center connections.
• C. Configure Path MTU Discovery and rely on fragmentation.
• D. MTU should be set to 1600 or greater across the data center network including inter-data center connections.

Correct answer: D

Explanation

VMware advises that the MTU should be at least 1600 to prevent fragmentation and ensure optimal performance in an NSX-T Data Center deployment. Options A and B suggest lower MTU settings which can lead to inefficiencies and potential issues with packet fragmentation. Option C, while a valid technique, does not meet the recommended MTU requirements set by VMware.
