This CCNA training is considered associate-level Cisco training, which means it was designed for junior network administrators. This 200-301 CCNA course is valuable for new IT professionals with at least a year of experience with networks and experienced network administrators looking to validate their Cisco skills.
Which statement correctly compares traditional networks and controller-based
Only controller-based networks decouple the control plane and the data plane.
and controller-based networks abstract policies from device configurations.
Only traditional networks natively support centralized management.
Only traditional networks offer a centralized control plane.
traditional devices use a distributed architecture, in which each control plane
is resided in a networking device. Therefore they need to communicate with each
other via messages to work correctly.
contrast to distributed architecture, centralized (or controller-based)
architectures centralizes the control of networking devices into one device,
called SDN controller.
What are two benefits of network automation? (Choose two.)
reduced hardware footprint
reduced operational costs
faster changes with more reliable results
fewer network failures
increased network security
Which two encoding methods are supported by REST APIs? (Choose two.)
Application Policy Infrastructure Controller (APIC) REST API is a programmatic
interface that uses REST architecture. The API accepts and returns HTTP (not
(JSON) or Extensible Markup Language (XML) documents.
What are two characteristics of a controller-based network? (Choose two.)
It uses Telnet to report system issues.
The administrator can make configuration updates from the CLI.
It uses northbound and southbound APIs to communicate between architectural
It decentralizes the control plane, which allows each device to make its own
It moves the control plane to a central point.
