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.

AA separate scope for the file server using a /32 subnet

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.

BA reservation for the server based on the MAC addressCorrect

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.

CA static IP address within the DHCP IP range

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.

DA SLAAC for the server

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.
