Application Layer Protocols

Question 1

refers to the TCP/IP protocol that specifies a reliable and efficient transfer of electronic mail service on the Internet

Answer 1

Simple Mail Transfer Protocol (SMTP)

Question 2

refers to a TCP/IP protocol that is designed to allow a workstation to retrieve mail that the server is holding for it.

Answer 2

Post Office Protocol, version 3 (POP3)

Question 3

is a small and simple alternative to FTP that uses UDP to transfer files between systems.

Answer 3

Trivial File Transfer Protocol (TFTP)

Question 4

refers to a TCP/IP protocol that enables the sharing of computer programs and/or data between hosts over a TCP/IP network. It uses TCP to create a virtual connection for control information and then creates a separate TCP connection for data transfer.

Answer 4

File Transfer Protocol (FTP)

Question 5

refers to a TCP/IP protocol that enables computers to mount drives on remote hosts and operate them as if they were local drives.

Answer 5

Network File System (NFS)

Question 6

refers to a TCP/IP protocol that is used on the Internet for translating names of domains and their publicly advertised network nodes into IP addresses.

Answer 6

Domain Name System (DNS)

Question 7

refers to a TCP/IP protocol that monitors and controls the exchange of management information between networks and network components

Answer 7

Simple Network Management Protocol (SNMP)

Question 8

collect and store management information and make this information available to NMSs using SNMP

Answer 8

Managed devices

Question 9

An .. has local knowledge of management information and translates that information into a form compatible to SNMP

Answer 9

agent

Question 10

executes applications that monitor and control managed devices. NMSs provide the bulk of the processing and memory resources required for network management.

Answer 10

NMS

Question 11

refers to a TCP/IP protocol that uses the TCP as the transport protocol to establish a connection between server and client.

Answer 11

Terminal Emulation protocol Network (Telnet)

Question 12

is a UNIX command that allows authorized users to log in to other UNIX machines on a network and to interact as if the user were physically at the host computer.

Answer 12

Remote login application (rlogin)

Question 13

refers to an application-level protocol service and an Internet standard developed by the IETF that supports the exchange of information on the World Wide Web, as well as on internal networks.

Answer 13

Hypertext Transfer Protocol (HTTP)

Question 14

is a secure message-oriented communications protocol designed for use in conjuction with HTTP

Answer 14

HTTPS

Question 15

is a security protocol that works at a socket level. This layer exists between the TCP layer and the application layer to encrypt/decode data and authenticate concerned entities.

Answer 15

Secure Sockets Layer (SSL)

Question 16

refers to a connection-oriented TCP/IP standard transport layer protocol that provides a reliable data delivery, duplicate data suppression, congestion control, and flow control on which many application protocols depend.

Answer 16

Transport Control Protocol (TCP)

Question 17

refers to a connectionless TCP/IP standard transport layer protocol that provides unreliable, best-effort service

Answer 17

User Datagram Protol (UDP)
