What is a Managed Device in the context of SNMP?

1. A software responsible for network data

2. A network node that allows access to specific information

3. A type of message sent to SNMP agents

4. An administrator's terminal for network management

The correct answer is: A network node that allows access to specific information

In the context of SNMP (Simple Network Management Protocol), a managed device refers to a network node that permits the retrieval and monitoring of specific information through SNMP. These devices, which can encompass routers, switches, servers, and other networked hardware, have an SNMP agent running on them. This agent is responsible for collecting and storing information about the device's operational status, performance statistics, and its configuration parameters. When a network management system, often referred to as a "manager," queries the managed device, it can use SNMP to access this information via the agent. The agent will then respond with the requested data, allowing for effective network monitoring, troubleshooting, and management. This ability to remotely access and manage device information is crucial for maintaining the health and performance of network infrastructure. Other options, such as software responsible for network data, messages sent to SNMP agents, or an administrator's terminal, do not accurately capture the specific role of a managed device within the SNMP framework. In contrast, describing a managed device as one that allows access to specific information encapsulates its primary purpose in network management effectively.
