What is the maximum number of IP addresses that can be assigned to hosts on a local subnet that uses the 255.255.255.224 subnet mask?

A) 15 B) 16
C) 30 D) 31
 
Answer & Explanation Answer: C) 30

Explanation:

A/27 (255.255.255.224) is 3 bits on and 5 bits off. This provides 8 subnets, each with 30 hosts. Does it matter if this mask is used with a Class A, B, or C network address? Not at all. The number of host bits would never change.

Q:

You are considering upgrading a Windows NT Workstation 4.0 computer on your network to Windows 2000 Professional. The computer has 12 applications installed in addition to the operating system. All the applications are compatible with Windows 2000. The end user would benefit from the additional features Windows 2000 provides. What action should you take? 

A) Upgrade the Windows NT Workstation 4.0 computer to Windows 2000 Server B) Upgrade the Windows NT Workstation 4.0 computer to Windows 2000 Professional
C) Perform a clean install of Windows 2000 Professional on the Windows NT Workstation 4.0 computer D) Don't upgrade the Windows NT Workstation 4.0 computer, but install the Directory Service Client on it instead
 
Answer & Explanation Answer: B) Upgrade the Windows NT Workstation 4.0 computer to Windows 2000 Professional

Explanation:

Upgrading the computer to Windows 2000 Professional is probably the best choice given that the current operating system is Windows NT Workstation 4.0 (which upgrades easily to Windows 2000 Professional) and the fact that the computer has 12 additional applications installed on it that would need to be reinstalled and reconfigured if a clean install was performed.
