Question 23/53
DHCP implements centralized management of IP addresses. The DHCP server, DHCP client, and DHCP relay exchange packets to distribute key parameters, including the IP address, subnet mask, gateway, and DNS. In addition, DHCP provides a conflict detection mechanism to prevent communication failures caused by IP address conflicts.
Correct Answer: A
* DHCP Overview :
* DHCP (Dynamic Host Configuration Protocol) is used to automate the assignment of IP addresses and other network configuration parameters (e.g., subnet mask, default gateway, DNS servers).
* It centralizes IP address management, reducing manual configuration errors.
* Key Components :
* DHCP Server : Allocates IP addresses and other parameters to clients.
* DHCP Client : Requests and receives configuration from the DHCP server.
* DHCP Relay : Forwards DHCP packets between clients and servers in different subnets.
* Conflict Detection Mechanism :
* DHCP includes a mechanism to detect and resolve IP address conflicts.
* Before assigning an IP address, the DHCP server sends an ICMP Echo Request to check if the address is already in use. If no response is received, the address is considered available.
* Why TRUE?
* The statement accurately describes the functionality of DHCP, including centralized management, parameter distribution, and conflict detection.
Thus, the correct answer is A .
