VMware NSX-T Data Center (VCP-NV 2019) — Question 44

An organization with two data centers is planning an active-active multi-site deployment of NSX-T Data Center.
The two data centers have this network connectivity configuration:
✑ Redundant 1Gbps links with 200 millisecond RTT
✑ Global load balancing is not being utilized
✑ 1600 MTU
✑ vSphere 6.5U2
Which configuration prevents the use of an active-active architecture?

Answer options

• A. vSphere 6.7 is the minimum supported version for active-active on vSphere
• B. 9000 MTU is required for active-active state replication
• C. global load-balancing is required to support NSX Manager DNS namespace
• D. RTT must be under 150 ms

Correct answer: D

Explanation

The correct answer is D because an RTT greater than 150 ms can lead to performance issues that are detrimental to the synchronization required in an active-active architecture. Option A is incorrect because vSphere 6.5U2 is sufficient for active-active deployment. Option B is wrong as 1600 MTU is adequate for NSX-T. Option C is also incorrect since global load balancing is not a prerequisite for NSX Manager DNS functionality.
