Network boundaries can be logical or physical. Which of the following are boundaries a network administrator cannot control?

A.
Informational

B.
Logical

C.
External

D.
Physical

Explanation:
External boundaries are those outside your network. This term does not refer to your network perimeter. A network administrator cannot control external boundaries. Answer options D and B are incorrect. Physical and logical boundaries are two broad classes of boundaries that are under your administrative control. Answer option A is incorrect. An information domain is a legitimate domain the administrator must address. Information domain arises from the practice of partitioning information resources according to access control, need, and levels of protection required.
