VMware NSX-T Data Center (VCP-NV 2019) — Question 71

While planning a NSX-T Data Center deployment with a network administrator, you are told the physical network uses Open Shortest Path First (OSPF) for the
Interior Gateway Protocol (IGP). The OSPF design is flat with the data center containing one OSPF area, area 0. The network administrator would like to extend area 0 into NSX-T so that dynamic routing updates will be learned bidirectionally.
Which meets the requirement?

Answer options

• A. Utilize static routes between the NSX-T topology and the physical network.
• B. Recommend creating a new area for NSX-T to protect NSX-T's control plane from Link State Advertisement (LSA) floods from OSPF area 0.
• C. Utilize the Border Gateway Protocol (BGP) on NSX-T and configure the physical network for route redistribution.
• D. Utilize multi-protocol Border Gateway Protocol (BGP) in the NSX-T topology and configure the physical network for route redistribution.

Correct answer: B

Explanation

The correct answer is B because creating a new area for NSX-T helps in isolating its control plane from potential Link State Advertisement (LSA) floods from the flat OSPF area 0, thereby enhancing stability and performance. Options A, C, and D do not address the specific requirement of protecting the NSX-T control plane from LSA floods and are not suitable for the given scenario.
