CCNA: Cisco Certified Network Associate — Question 309

How does Cisco DNA Center gather data from the network?

Answer options

• A. Devices use the call-home protocol to periodically send data to the controller
• B. Devices establish an IPsec tunnel to exchange data with the controller
• C. The Cisco CLI Analyzer tool gathers data from each licensed network device and streams it to the controller
• D. Network devices use different services like SNMP, syslog, and streaming telemetry to send data to the controller

Correct answer: D

Explanation

The correct answer is D because Cisco DNA Center relies on multiple services like SNMP, syslog, and streaming telemetry to gather data effectively from network devices. Options A and B describe specific methods that are not utilized by Cisco DNA Center for data collection, while option C refers to a tool that does not represent the primary data-gathering process used by the controller.
