The correct answer is A. MAC address reservation.
When a device connects to a network, it is assigned an IP address lease by a DHCP (Dynamic Host Configuration Protocol) server. This lease specifies how long the IP address will be valid for the device. After the lease expires, the device must request a new lease.
A MAC address reservation is a configuration setting on a DHCP server that assigns a specific IP address lease to a device with a specific MAC address. This means that whenever the device with that MAC address connects to the network, it will always receive the same IP address lease.
This is useful in situations where a device requires a consistent IP address for applications or services to work correctly, but the IP address lease is subject to change based on the network configuration. By reserving an IP address lease based on the device's MAC address, the device can always maintain the same IP address on the network.
Static IP addresses (B) are manually assigned IP addresses that do not change. This is another option for devices that require a consistent IP address, but it requires manual configuration and does not offer the flexibility of a DHCP server.
IP address exclusion (C) is a DHCP server setting that prevents specific IP addresses from being assigned to devices. This is useful for reserving IP addresses for servers or other devices that require a static IP address.
Custom DNS server entry (D) is a setting that specifies the DNS (Domain Name System) server that a device should use for name resolution. This does not have any effect on the assignment of IP addresses to devices on the network.
