   A network administrator is managing a /24 subnet with a mix of static and DHCP-assigned addresses. The IP documentation is a spreadsheet that is manually updated. A new server is added with a static IP that falls within the DHCP scope. The DHCP server does not have an exclusion for this address. Two weeks later, a workstation receives the same IP from DHCP, causing a conflict. The administrator wants to implement a solution that prevents this class of problem without requiring manual spreadsheet updates. Which solution is the MOST effective?

   • AEnable DHCP snooping on the switch to block unauthorized DHCP servers.
   • BRequire all static IP assignments to be documented in a central database.
   • CMove the server to a different subnet that is not used by DHCP.
   • DConfigure the DHCP server to use a reservation for the server's MAC address.
