b. Users from inside the organization can use resources from the DMZ.
c. DMZs permit access to specific servers or services by users from outside of an organization.
d. Organizations can operate multiple DMZs as long as they have the same security configuration for each.

Answer 1

DMZs allow users from inside and outside an organization to access certain services.

Understanding the statements related to DMZs will clarify their function and design:

However, statement a is incorrect. DMZs should not permit all traffic from the internet; rather, only specific traffic necessary to access the services should be allowed. Unrestricted access could lead to security breaches.
