Which statement regarding the IP address lease provided by a DHCP server is false?

• A. The lease renewal timer is 50% of the total lease
• B. The rebinding timer is 87.5% of the total lease
• C. The DHCP client keeps sending DHCP Request packets to the server regardless of responses
• D. The DHCP client does not require periodic communication with the server

Answer: (D)

The correct answer highlights the nature of DHCP (Dynamic Host Configuration Protocol) operations. In a typical DHCP lease process, the client receives a temporary IP address assignment from the DHCP server for a specified duration known as the lease time. A crucial aspect of this process is the communication that takes place between the DHCP client and the DHCP server. The statement about the DHCP client not requiring periodic communication with the server is false because, during the lease period, the client must periodically attempt to renew its lease with the server. This is accomplished through the DHCP Request packets, which the client sends according to specified timers: the lease renewal timer and the rebinding timer. The lease renewal timer is usually set to 50% of the lease time; when this timer expires, the client tries to extend its lease by sending a request to the original server. If it fails to get a response, it will continue to send requests until it reaches 87.5% of the lease time, at which time it enters the rebinding phase, where it may broadcast its requests to any available DHCP server. Thus, the concept that the DHCP client does not require periodic communication with the server contradicts the fundamentally required behavior of DHCP clients to ensure they maintain an active and valid
