Protocol for Health Status Polling

B.

The correct answer is B. SNMP (Simple Network Management Protocol).

Cisco Prime Collaboration Assurance is a network management system that provides real-time monitoring, proactive troubleshooting, and long-term trending and analysis of the health of a Cisco Collaboration environment. It monitors various systems and components in the environment, such as servers, gateways, endpoints, and applications, and collects data about their performance and availability.

To collect this data, Cisco Prime Collaboration Assurance uses SNMP, a standard protocol for network management. SNMP is a protocol that allows network devices to be managed and monitored from a central location, by exchanging messages between the devices and the management system. The messages contain information about the device's configuration, performance, and status, and can be used to detect and diagnose problems in the network.

SNMP works by using a hierarchical structure of objects, called Management Information Bases (MIBs), that define the data that can be collected from each device. Each MIB contains a set of variables, called objects, that represent specific aspects of the device's configuration or status. The SNMP management system can request these objects from the device, and receive their values in response.

In the case of Cisco Prime Collaboration Assurance, SNMP is used to poll the MIBs of different systems in the Collaboration environment, such as Cisco Unified Communications Manager (CUCM), Cisco Unity Connection (CUC), and Cisco Unified Contact Center Express (UCCX). The MIBs contain information about the health of these systems, such as CPU usage, memory usage, disk space, call processing statistics, and error logs. Cisco Prime Collaboration Assurance collects this data at regular intervals, and uses it to generate reports, alerts, and dashboards that show the overall health of the Collaboration environment, as well as specific issues that need attention.

In conclusion, SNMP is the protocol that Cisco Prime Collaboration Assurance uses to poll the health status of different systems in the Collaboration environment, by collecting data from their MIBs. This allows the system to monitor and manage the performance and availability of the Collaboration environment, and to detect and diagnose problems before they become critical.
