VMware NSX 4.x Professional (2024) — Question 14

What is VMware’s recommendation for the minimum MTU requirements when planning an NSX deployment?

Answer options

• A. MTU should be set to 1700 or greater 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 1550 or less across the data center network including inter-data center connections.

Correct answer: A

Explanation

VMware recommends setting the MTU to 1700 or higher to ensure optimal performance and to avoid fragmentation issues in NSX deployments. Options B and D suggest lower MTU values that do not meet VMware's guidelines, while option C relies on Path MTU Discovery, which is not the preferred method for NSX configurations.
