Describe how a Linux DHCP reservation differs from a dynamic range assignment in terms of what the administrator configures.
Answer
A dynamic range defines addresses available for clients in a subnet. A reservation uses a host-specific configuration associated with a client’s MAC address so that the client is assigned a particular address. The reservation is defined in the Linux DHCP configuration file, with attention to braces and semicolons.
Explanation
A dynamic range describes a pool of addresses from which the server can lease addresses to clients. A reservation is more specific: the administrator associates a particular client’s MAC address with a desired address so the client can receive a consistent assignment. The course material shows reservations being added in the Linux configuration and cautions administrators to use correct braces and semicolons. The distinction is between a general pool and a host-specific mapping; both are managed by the DHCP server. **Key takeaway:** A range serves a pool of clients, while a MAC-based reservation targets a particular device.\n\n**Glossary:** **Reservation**: A DHCP configuration that associates a client identifier, such as a MAC address, with a specific IP address.
