To answer this question, you need to understand the concept of network management protocols.
Network management protocols are used to monitor, control, and manage network devices and resources. They provide a standardized way of communication between network management systems and network devices.
Let's go through each option to understand why it is correct or incorrect:
Option A) SGMP - This option is incorrect because SGMP (Simple Gateway Monitoring Protocol) is not a network management protocol. It is an obsolete protocol that was used for managing gateways.
Option B) SNMP - This option is correct because SNMP (Simple Network Management Protocol) is a widely used network management protocol. It is used for monitoring and managing network devices such as routers, switches, and servers.
Option C) CMIP - This option is incorrect because CMIP (Common Management Information Protocol) is a network management protocol, but it is not as widely used as SNMP. It is used in some specific environments, but SNMP is more commonly used.
Option D) MMC - This option is incorrect because MMC (Microsoft Management Console) is not a network management protocol. It is a graphical user interface (GUI) framework used for managing Windows-based systems.
The correct answer is B) SNMP. This option is correct because SNMP is a widely used network management protocol.
