As a CCNA candidate, you will be expected to know the OSI model very well. Which of the following are associated with the application layer (layer 7) of the OSI model? (Choose two)A. TCPB. TelnetC. FTPD. PingE. IPF. UDP
Which one of the following protocols uses both UDP and TCP ports for the transport layer operation?A．FTPB．TFTPC．SMTPD．TelnetE．DNS
TCP functions at the Open System Interconnection(OSI)(61)layer, or Layer 4. Its chief responsibility is to ensure(62)end-to-end connectivity. IP, located one layer down, at the OSI network layer, or Layer 3, communicates the addresses of each(63)sender and receiver to the routers along the way. Routers and Layer 3 switches can read IP and other Layer 3(64). This information, combined with routing tables and other network intelligence, is all it takes to get(65)the room or around the world via TCP/IP.A．transposeB．translateC．transmitD．transport
● TCP/IP （71） layer protocols provide services to the application （72） running on a computer. The application layer does not define the application itself, but rather it defines （73） that applications need—like the ability to transfer a file in the case of HTTP. In short, the application layer provides an （74） between software running on a computer and the network itself. The TCP/IP application layer includes a relatively large number of protocols, with HTTP being only one of those. The TCP/IP （75） layer consists of two main protocol options—the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP).
