The correct answer is B. A reservation for the server based on the MAC address. For a file server that needs a consistent IP address within a DHCP-managed network, configuring a DHCP reservation based on its MAC address is the best solution as it provides a stable IP while still leveraging the existing DHCP infrastructure.
Question
A network administrator needs to set up a file server to allow user access. The organization uses DHCP to assign IP addresses. Which of the following is the best solution for the administrator to set up?
Options
- AA separate scope for the file server using a /32 subnet
- BA reservation for the server based on the MAC address
- CA static IP address within the DHCP IP range
- DA SLAAC for the server

Why each option
For a file server that needs a consistent IP address within a DHCP-managed network, configuring a DHCP reservation based on its MAC address is the best solution as it provides a stable IP while still leveraging the existing DHCP infrastructure.
A separate scope for a single file server with a /32 subnet is an impractical and overly complex solution, as /32 typically represents a single host route and doesn't fit the context of a server on a DHCP-managed network.
A DHCP reservation ensures that a specific device, like a file server, always receives the same IP address from the DHCP server based on its unique MAC address. This provides a consistent IP for the server, which is crucial for reliable access, while still allowing the DHCP server to manage the IP addressing scheme.
While assigning a static IP address within the DHCP IP range *can* work, it creates a potential for IP address conflicts if the DHCP server later tries to assign that same address to another client. A reservation is safer.
SLAAC (Stateless Address Autoconfiguration) is used for IPv6 address assignment without a DHCP server, which is not applicable to an IPv4 DHCP environment for a server needing a fixed address.
