Introduction to Dynamic Host Configuration Protocol
Dynamic Host Configuration Protocol (DHCP) is a fundamental networking protocol used to automate the assignment of IP addresses, subnet masks, default gateways, and other network configuration parameters to client devices. For students preparing for the CCNA 200-301 exam, understanding DHCP operation is crucial.
This article explores which statement is true about DHCP operation based on the CCNA 1 ITN (v5.0.3 + v6.0) Final Exam and CCNA 200-301 study material. Additionally, we will highlight how Study4Pass provides the best resources for mastering DHCP and other networking concepts.
What is DHCP?
DHCP is a client-server protocol that dynamically assigns IP addresses and network configurations to devices, eliminating the need for manual IP configuration. It operates on UDP ports 67 (server) and 68 (client) and follows a four-step process known as DORA (Discover, Offer, Request, Acknowledgment).
Key Benefits of DHCP
- Automates IP address management
- Reduces configuration errors
- Supports dynamic and static IP allocation
- Enables efficient reuse of IP addresses
Which Statement is True About DHCP Operation?
Several statements describe DHCP operation, but only a few are accurate. Below, we analyze the correct statements based on CCNA 200-301 exam objectives:
1. DHCP Uses a Four-Step Process (DORA) for IP Assignment
True – The DHCP process involves:
- Discover: The client sends a DHCPDISCOVER broadcast to locate a DHCP server.
- Offer: The server responds with a DHCPOFFER containing an available IP address.
- Request: The client requests the offered IP via DHCPREQUEST.
- Acknowledgment: The server confirms with DHCPACK, finalizing the assignment.
2. DHCP Servers Assign IP Addresses Permanently
False – DHCP can assign dynamic (temporary) or static (reserved) IPs, but most assignments are leased for a limited time.
3. DHCP Works Only Within the Same Subnet
False – DHCP relies on broadcast traffic, but DHCP relay agents (like routers) can forward requests across subnets.
4. Clients Must Renew Their IP Lease Periodically
True – DHCP leases expire, so clients must renew them before the lease time ends (usually at 50% of the lease duration).
5. DHCP Can Provide Additional Configuration Parameters
True – Besides IP addresses, DHCP can assign:
- Subnet mask
- Default gateway
- DNS servers
- Domain name
