What is the function of an SNMP Manager?

The function of an SNMP Manager is indeed to obtain data from SNMP agents and manage them. SNMP, which stands for Simple Network Management Protocol, is extensively used for network management. The SNMP Manager acts as a centralized system that communicates with various SNMP agents, which are located on network devices such as routers, switches, and servers.

In this context, the SNMP Manager collects data about the network devices - such as their performance, status, and configuration settings - by sending requests to the SNMP agents. The managers then process this information, allowing network administrators to monitor the health and performance of the entire network. This centralized management capability is crucial for effective network administration, making it easier to identify issues, optimize performance, and ensure security.

The other options describe functions that do not relate specifically to the role of an SNMP Manager. For instance, the encryption of communications relates more to security protocols rather than SNMP management. Similarly, connecting two separate networks pertains to routing and gateway functions rather than management. Analyzing traffic flow in real-time involves network monitoring tools that perform different functions than those of the SNMP Manager. Thus, option C accurately captures the primary responsibility of an SNMP Manager in the realm of network management.
