Which protocol does DHCP use at the Transport layer?

[A]. IP
[B]. TCP
[C]. UDP
[D]. ARP

Answer: Option C

Explanation:

User Datagram Protocol is a connection network service at the Transport layer, and DHCP uses this connectionless service.

It is chiefly used by the operating systems of networked computers to send error messages.

DHCP :Dynamic Host Configuration Protocol

Manu said: (Jul 27, 2013)  
What is main purpose of DHCP protocol?

Naga Venu said: (Dec 11, 2013)  
The Dynamic Host Configuration Protocol (DHCP) is a standardized networking protocol used by servers on an IP computer network to allocate IP addresses to computers. The purpose of DHCP is to automate the IP address configuration of a computer without a network administrator. IP addresses are typically selected from a range of assigned IP addresses stored in a database on the server and issued to a computer which requests a new IP address. An IP address is assigned to a computer for a set interval. After which, the computer must acquire a new IP address from the server. The computer may request to the server to have the interval extended, increasing the time that the computer may use the IP address for. The server may refuse to extend the time, forcing the computer to request a new IP address once the interval has elapsed.

Can you explain more functions of UDP ? & How its Works ?

Pmm said: (Jan 27, 2014)  
User datagram protocol. It's wireless protocol. It automatically assign the IP address. Range will different.

In UDP there no acknowledgement, but DHCP process there will be acknowledgement.

What is DHCP?and why to used transport layer?

What is Transport layer?

Rahulk said: (Jan 30, 2015)  
User data gram protocol is connection less but in explanation it is written as connection network service why?

Ajit said: (Mar 31, 2015)  
In UDP there is no any acknowledgement send by client to server. But in TCP acknowledgement is sent by client to server for data receiving.

Then how DHCP stand for UDP?

Jayadeepreddy said: (May 12, 2015)  
What is the range of UDP?

Sampath said: (Sep 23, 2015)  
Its depend on the IP address.

Athira said: (Dec 18, 2015)  
TCP is reliable protocol and UDP is unreliable. Then why we use UDP for this?

What is the benefit using UDP?

Balaji T said: (Oct 3, 2016)  
TCP drawback is it is a point to point protocol, so not useful for multicast or broadcast applications. yes UDP is unreliable but few advantages also there low overhead, fast etc.

Vic Key said: (Nov 16, 2016)  
please tell the Difference between connection-oriented and reliable protocol.

Vishal said: (Aug 20, 2017)  
UDP is useful for fast transferring the data while the integrity of the data isn't important.
For ex, Voice call.

TCP is connections oriented but has few disadvantages over UDP in terms of speed.

As it gets ack after delivering a data it requires more time.

For Ex. SMS both TCP, UDP are important in networking as per there functions,

What is meant by ARP?

Kalyani said: (Jul 9, 2018)  
ARP means address resolution protocol.

It is used for mapping of IP address to the hardware or physical address which is known as ethernet address.

Mani said: (Aug 7, 2019)  
UDP is a connectionless oriented protocol. There is no three-way handshake.

Prajwal Naik said: (Sep 29, 2020)  
Can anybody explain why DHCP use only UDP why not TCP? I know UDP is fast rather than this, Is there any other reason?
