An architect for a company’s private cloud utilizes software-defined networking with the expectation of service microsegmentation. The architect intends to use
MAC addresses printed on the network cards for ingress/egress filtering of each VM. Which aspect of virtualization initially impedes the architect’s success?
A. The MAC addresses are indistinguishable; the hypervisor stacks all the addresses on a single network interface.
B. The hypervisor translates only TCP/IP addresses from the virtual machines to MAC addresses.
C. The MAC addresses are not used for ingress/egress filtering; the architect must use TCP/IP.
D. The virtual machines are not allowed to access the hardware-based MAC address directly.
