What are two characteristics of a controller-based network? (Choose two.)

A. It uses Telnet to report system issues.
B. The administrator can make configuration updates from the CLI.
C. It uses northbound and southbound APIs to communicate between architectural layers.
D. It decentralizes the control plane, which allows each device to make its own forwarding decisions.
E. It moves the control plane to a central point.

Which statement compares traditional networks and controller-based networks?

A. Only controller-based networks decouple the control plane and the data plane.
B. Traditional and controller-based networks abstract policies from device configurations.
C. Only traditional networks natively support centralized management.
D. Only traditional networks offer a centralized control plane.

How does Cisco DNA Center gather data from the network?

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

What are two fundamentals of virtualization? (Choose two.)

A. It allows logical network devices to move traffic between virtual machines and the rest of the physical network.
B. It allows multiple operating systems and applications to run independently on one physical server.
C. It allows a physical router to directly connect NICs from each virtual machine into the network.
D. It requires that some servers, virtual machines, and network gear reside on the Internet.
E. The environment must be configured with one hypervisor that serves solely as a network manager to monitor SNMP traffic.
