In a data center using a leaf and spine architecture, which two statements define the connectivity between the leaf and spine tiers required to provide optimal
network connectivity for NSX? (Choose two.)

A.
Links are required between leaf and spine switches, and from each spine switch to other spine switches in the architecture.

B.
Links are required between leaf and spine switches in the architecture to form a point-to-point connection between the two tiers.

C.
High availalability and scalability should be achieved using NSX High Availability.

D.
High availability and scalability should be achieved using Equal Cost Multipathing (ECMP).
