Question 6
Which benefit does Cisco DNA Center provide over traditional campus management?

- B: Cisco DNA Center handles management tasks at the controller to reduce the load on infrastructure devices, and traditional campus management uses the data backbone.
- C: Cisco DNA Center automatically compares security postures among network devices, and traditional campus management needs manual comparisons.
- D: Cisco DNA Center correlates information from different management protocols to obtain insights, and traditional campus management requires manual analysis.
