An architect is responsible for designing a vSphere-based solution for a customer.

For NIC Teaming, all NICs in the same port group must be in the same layer 2 broadcast domain.

This is a key consideration for NIC teaming. All NICs in a team must be in the same Layer 2 broadcast domain to ensure that traffic is properly routed and that the NIC team can work as expected within the vSphere environment. This is necessary for network redundancy and communication consistency.

To increase availability, the NICs within a NIC team should be from different physical NIC Cards.

To eliminate single points of failure, NICs within the same NIC team should be sourced from different physical NIC cards. This way, if one physical NIC card fails, the other NICs in the team will still be able to handle network traffic, ensuring availability.

NIC Teaming requires a minimum of two physical network connections.

NIC Teaming relies on having at least two physical NICs for redundancy and load balancing. This is a basic requirement to prevent single points of failure in network connectivity. With only one NIC, there would be no fault tolerance.
