A. B. C. D.D.
Cisco DNA Center is a network automation and management platform that allows administrators to manage their network infrastructure from a central location. One of the key features of DNA Center is its ability to gather data from network devices to provide visibility into network health and performance.
To gather data from the network, Cisco DNA Center uses various methods and protocols. The correct answer to the question is D. Network devices use different services like SNMP, syslog, and streaming telemetry to send data to the controller.
Let's explore each of these methods in more detail:
Simple Network Management Protocol (SNMP): SNMP is a protocol used to manage and monitor network devices. It allows devices to send information, such as interface status, CPU utilization, and memory usage, to a management station like Cisco DNA Center. SNMP is widely supported by network devices and is often used to collect data from switches, routers, and other network infrastructure devices.
Syslog: Syslog is a standard protocol used for message logging on IP networks. Network devices can send log messages to a syslog server, which can then be collected and analyzed by tools like Cisco DNA Center. Syslog messages can provide information about system events, errors, and warnings, allowing administrators to troubleshoot issues and monitor network health.
Streaming Telemetry: Streaming telemetry is a newer method of collecting data from network devices. It allows devices to continuously stream data to a collector, like Cisco DNA Center, in real-time. Streaming telemetry provides a more granular view of network performance, allowing administrators to monitor individual interfaces, traffic flows, and other metrics in real-time.
In summary, Cisco DNA Center gathers data from the network using various methods, including SNMP, syslog, and streaming telemetry. These protocols allow devices to send information about network health, performance, and events to a centralized management station, providing administrators with visibility into their network infrastructure.
