DHCPv4 Concepts

Play an AI-generated podcast conversation about this lesson

What is the purpose of using DHCP (Dynamic Host Configuration Protocol) in a network?

To manually troubleshoot IP address conflicts

To statically allocate IP addresses to computers, laptops, and smartphones

To assign IP addresses to network devices like routers, switches, and servers (correct)

To eliminate the need for IP addresses

Why is it easy to make a mistake when dealing with statically configured IP addresses?

The configuration parameters are exact

There is no possibility of IP address conflicts

The DHCP server cannot minimize errors

Typographical errors are difficult to troubleshoot (correct)

What happens if an IP address conflict occurs between two devices in a network?

The network automatically assigns a new IP address to one of the conflicting devices

The conflict has no impact on network connectivity

The devices ignore the conflict and continue to function normally

One or both of the devices cannot be connected (correct)
