Click on the arrows to vote for the correct answer
A. B. C. D. E.CD.
SNMP (Simple Network Management Protocol) is a protocol used to manage and monitor network devices. It operates at the application layer of the OSI model and is used to collect and organize information about devices in a network.
The correct statements about SNMP are:
B. NMS sends a request to the agent at TCP port 161. SNMP messages are sent between an SNMP manager, also known as a Network Management Station (NMS), and an SNMP agent, which runs on the managed device. The SNMP manager sends requests to the SNMP agent on TCP port 161 to gather information about the device.
D. NMS receives notifications from the agent on UDP 162. In addition to sending requests, SNMP can also send notifications from the SNMP agent to the SNMP manager to alert it to specific events, such as a device going offline. These notifications are sent to the SNMP manager on UDP port 162.
A. SNMP operates at Layer-6 of the OSI model is false. SNMP operates at the application layer (Layer-7) of the OSI model, which is the highest layer.
C. NMS sends request to the agent from any source port is false. SNMP requests are sent from the SNMP manager to the SNMP agent on TCP port 161. The source port is a dynamically allocated port number.
E. MIB is a hierarchical representation of management data on NMS is true. SNMP uses Management Information Bases (MIBs) to organize and represent management data. MIBs are a hierarchical structure that defines the objects, or variables, that can be managed using SNMP.
In summary, SNMP is a protocol used to manage and monitor network devices. SNMP messages are sent between an SNMP manager and an SNMP agent. The correct statements about SNMP are that the NMS sends a request to the agent at TCP port 161, the NMS receives notifications from the agent on UDP 162, SNMP operates at the application layer of the OSI model, the NMS sends requests to the agent from a dynamically allocated source port, and MIB is a hierarchical representation of management data on NMS.
