A data center has a mix of servers that need Layer 2 adjacency for clustering and servers that only need Layer 3 connectivity. The network team wants to minimize the Layer 2 fault domain while providing the necessary connectivity. What is the best design approach?

Put all servers in a single large VLAN to simplify the design

Route all traffic at Layer 3 and do not provide Layer 2 adjacency

Use MC-LAG to connect all servers to the same pair of switches

Use EVPN-VXLAN to provide Layer 2 overlay only for the servers that need it, and route all other traffic at Layer 3

In a data center network, what is the primary difference between Layer 2 switching and Layer 3 routing?

Layer 2 switching forwards frames based on MAC addresses, while Layer 3 routing forwards packets based on IP addresses.

Layer 2 switching uses IP addresses to forward frames, while Layer 3 routing uses MAC addresses.

Layer 2 switching is used only for wireless networks, while Layer 3 routing is used only for wired networks.

Layer 2 switching operates at the network layer, while Layer 3 routing operates at the data link layer.
