A) To assign a permanent IP address to a device B) To assign a temporary IP address to a device C) To assign a unique MAC address to a device D) To assign a unique hostname to a deviceAnswer: B) To assign a temporary IP address to a device Explanation: In a dynamic IP addressing configuration, a DHCP lease is a period of time during which a device is assigned a specific IP address. When a device connects to a network and requests an IP address from a DHCP server, the server assigns an available address to the device and specifies a lease period. The lease period is the length of time for which the device is allowed to use the assigned IP address. At the end of the lease period, the device must request a new lease in order to continue using the IP address. This allows the DHCP server to reuse IP addresses that are no longer in use, ensuring that there are enough available addresses for all devices on the network.
