Bob, a system administrator at TPNQM SA, concluded one day that a DMZ is not needed if
he properly configures the firewall to allow access just to servers/ports, which can have
direct internet access, and block the access to workstations.
Bob also concluded that DMZ makes sense just when a stateful firewall is available, which
is not the case of TPNQM SA.
In this context, what can you say?

A.

Bob can be right since DMZ does not make sense when combined with stateless
firewalls

B.

Bob is partially right. He does not need to separate networks if he can create rules by
destination IPs, one by one

C.

Bob is totally wrong. DMZ is always relevant when the company has internet servers
and workstations

D.

Bob is partially right. DMZ does not make sense when a stateless firewall is available
