Which of the following protocols is not typically associated with the Application layer of the TCP/IP model?  (1 Point)FTPDNSSMTP UDP

1. ### Break Down the Problem

To identify which protocol is not typically associated with the Application layer of the TCP/IP model, we need to understand the common protocols associated with each layer.

2. ### Relevant Concepts

The TCP/IP model has four layers:

• Application Layer
• Transport Layer
• Internet Layer
• Link Layer

The protocols in question are:

• FTP (File Transfer Protocol) - Application Layer
• DNS (Domain Name System) - Application Layer
• SMTP (Simple Mail Transfer Protocol) - Application Layer
• UDP (User Datagram Protocol) - Transport Layer

3. ### Analysis and Detail

1. FTP: Used for transferring files across the Internet and operates at the Application layer.
2. DNS: Resolves domain names to IP addresses, also functioning at the Application layer.
3. SMTP: Used for sending emails, fits within the Application layer as well.
4. UDP: This is a connectionless communication protocol that operates at the Transport layer, not the Application layer.

4. ### Verify and Summarize

From the above analysis, UDP is the only protocol listed that does not belong to the Application layer.

Final Answer

UDP is the protocol not typically associated with the Application layer of the TCP/IP model.
