Which of the following protocols would be involved in the implementation of a router and an interconnectivity
device monitoring system?

A.
Simple Network Management Protocol

B.
File Transfer Protocol

C.

D.
Telnet

Explanation:
The Simple Network Management Protocol provides a means to monitor and control network devices and to
manage configurations and performance. The File Transfer Protocol (FTP) transfers files from a computer on
the Internet to the user’s computer and does not have any functionality related to monitoring network devices.
Simple Mail Transfer Protocol (SMTP) is a protocol for sending and receiving e-mail messages and does not
provide any monitoring or management for network devices. Telnet is a standard terminal emulation protocol
used for remote terminal connections, enabling users to log into remote systems and use resources as if they
were connected to a local system; it does not provide any monitoring or management of network devices.
