What is a reason that Layer 2 switches are used to build networks in a virtualized data
center rather than Layer 3 switches?
A.
Layer 2 switches are less expensive than Layer 3 switches.
B.
The convergence time of a Layer 2 network is faster than that of a Layer 3 network.
C.
A virtual machine can move from one physical server to another in a Layer 2 network
without needing a different IP address.
D.
A virtual machine can move from one physical server to another in a Layer 2 network
without needing different TCP port numbers.
