Which Protocol is Used for Monitoring and Managing Network Devices?

A.

The protocol primarily used for monitoring and managing network devices is Simple Network Management Protocol (SNMP), which is option A.

SNMP is a protocol used to manage and monitor network devices, such as routers, switches, servers, and printers. It allows network administrators to monitor network performance, troubleshoot problems, and manage network devices remotely. SNMP works by collecting and organizing information about network devices in a standardized way, making it easy to manage and monitor them.

SNMP uses a client-server model, where the network devices act as servers and the SNMP manager acts as the client. The SNMP manager sends requests to the network devices to retrieve information, such as CPU usage, memory utilization, and network traffic statistics. The network devices respond to these requests by sending back the requested information.

SNMP also allows network administrators to configure network devices remotely. For example, an administrator can use SNMP to configure the network device to send an alert if a certain threshold is reached, or to configure security settings.

In contrast, SMTP (Simple Mail Transfer Protocol) is used for sending and receiving email messages, FTPS (File Transfer Protocol Secure) is used for secure file transfer, and NTP (Network Time Protocol) is used for synchronizing time between network devices. These protocols are not primarily used for monitoring and managing network devices.
