12. Situation:
You are designing a NetBIOS naming scheme for all of the servers and client computers at your location. Within 2 years your company will install a WAN that will connect all of its networks.
Current Network Configuration for the Entire company
| Server | 328, Which run Microsoft Windows NT Server |
| Client Computers | 20,000 which run Microsoft Windows 95 |
| Network | 40, each in a different city |
| WAN connections | None |
| All users have e-mail to all other users in the company. | |
| E-mail names | All have 12 characters or fewer |
Current Network Configuration for Your Location
| Server | 10, which run Microsoft Windows NT server |
| Client Computers | 500, which run Microsoft Windows 95 |
Required results:
You must successfully implement the NetBIOS naming scheme for all servers and client computers at your location.
The NetBIOS naming scheme at your location must continue to work after the WAN is connected.
Optional desired results:
You want the NetBIOS name for each server to describe
the server's department or function.
You want each client computer's NetBIOS name to describe the computer's primary user or
function.
Proposed solution:
Assign each server and client computer at all locations a unique 15-digit hexadecimal number to be used as that computer's NetBIOS name.
Which results does the proposed solution produce?
A. The proposed solution produces the required results and produces both of the optional desired results.
B. The proposed solution produces the required results and produces only 1 of the optional desired results.
C. The proposed solution produces the required results
but does not produce either of the
optional desired results.
D. The proposed solution does not produce the required results. <<<<<
