Which of the following application-layer protocols are based on TCP?
FTP (File Transfer Protocol) and HTTP (Hypertext Transfer Protocol) are both application-layer protocols that rely on TCP for establishing connections and ensuring reliable data transfer. FTP uses TCP for its control and data channels to manage the transfer of files efficiently, whereas HTTP, used for transmitting web pages, also operates over TCP to ensure reliable communication. Ping uses ICMP, which is not a TCP-based protocol, and TFTP primarily uses UDP, making both unsuitable choices based on the given options.

The correct answer is C. FTP (File Transfer Protocol). Ping: Uses the ICMP protocol, which operates at the network layer and doesn't utilize TCP. TFTP (Trivial File Transfer Protocol): While sometimes categorized as an application-layer protocol, it primarily uses UDP for datagram-based transfers, not TCP. FTP: Employs TCP to establish a reliable connection and deliver data packets for file transfers. HTTP packet: HTTP works within the application layer but itself isn't a protocol; it defines the format and structure of messages used by various protocols that can run on top of TCP or UDP.
