Hypervisor
Which cloud service provides IT managers with access to network equipment, virtualized services, and supporting network infrastructure and best for new organization that cannot afford physical servers and networking equipment and must purchase network services on-demand?
IaaS (infrastructure as a service)
Which characteristic best describes the control plane of a networking device?
Information sent to this plane is processed by the CPU. This plane makes forwarding decisions. This plane contains router protocol neighbor and topology tables.
Which of the following APIs would be used exclusively between computing devices within Cisco?
Internet or private API
What is an architectural constraint to which a true RESTful API web service must adhere?
It runs as client/server model.
Which of the following make up query portion of RESTful request?
Key Format Parameters
This is a table that triggers a variety of performance-related actions on a flow including the ability to rate-limit the traffic.
Meter table
You use online banking to pay a bill. You adjust the volume on the television set with a remote control. You open your car door with a remote control.
Not automation
Which of the following APIs is used by Cisco to provide access to students to complete labs?
Open or public API
Identify the term for the following definition in relationship to configuration management tools: The process of how all automated activities need to happen, such as the order they must be done and what must be completed before another task is begun. Which term describes the process of managing configuration changes of network devices in an orderly fashion?
Orchestration
Which cloud service provides programmers access to development tool and services used to deliver applications and best for organization that needs to collaboratively create applications and deliver them over web?
PaaS (Platform as a service)
Which of the following APIs would be used exclusively between Google and Cisco? Which types of APIs are suitable for data communication between travel website and hotel chain inquiring about room availability data?
Partner API (Application Programming Interface)
A programmer is using Ansible as the configuration management tool. Which term is used to describe a set of instructions for execution?
Playbook
This type of SDN uses built-in applications that automate advanced configuration tasks via guided workflow and user-friendly GUI. No programming skills are required.
Policy-based SDN
Which characters are used to enclose a JSON key?

SDN (Software Defined Networking)
This is a logical entity that enables network administrators to manage and dictate how the data plane of switches and routers should handle network traffic.
SDN controller

For a data center, what is the difference in the server virtualization data traffic compared with the traditional client-server model?
There are significant data exchanges between virtual servers.

Which function of the Cisco intent-based networking system (IBNS) enables network operators to express the expected networking behavior that will best support the business intent?
Translation
A Type 1 hypervisor requires a management console to manage the hypervisor. East-West traffic is exchanged between virtual servers in the same data center. An API is a set of rules describing how one application can interact with another, and the instructions to allow the interaction to occur. Agentless means that the controller or master pushes the configuration to the controlled device.

Type 2 Hypervisor
What technology separates the OS from the hardware?
Virtualization

What is a difference between the XML and HTML data formats?
XML uses self-descriptive data structure but HTML uses standard document structure.
