Answers | Latest Update | 2024/2025 |
Rated A+
What is the purpose of the Cisco DevNet platform?
✔✔The Cisco DevNet platform provides tools, resources, and a community for developers to
build, manage, and automate applications and networks using Cisco technologies.
Explain the function of APIs in network automation.
✔✔APIs (Application Programming Interfaces) allow developers to programmatically interact
with network devices and systems, enabling automation, configuration, and data retrieval without
manual intervention.
What is RESTful API, and why is it important in modern networking?
✔✔A RESTful API is an architectural style for designing networked applications. It is important
because it enables stateless communication using HTTP requests for operations like GET, POST,
PUT, and DELETE, making it scalable and easy to integrate with various services.
Describe the role of Python in network automation.
1
,✔✔Python plays a crucial role in network automation as it offers simplicity, extensive libraries,
and frameworks that make it easy to write scripts to automate repetitive network tasks, manage
devices, and collect data from APIs.
What is Cisco DNA Center, and how does it support network automation?
✔✔Cisco DNA Center is a centralized network management and automation platform that
provides insights, automation, and programmability for managing enterprise networks, helping
reduce manual tasks and improving operational efficiency.
How does Ansible help in automating network tasks?
✔✔Ansible helps automate network tasks by providing a simple, agentless automation
framework that uses playbooks written in YAML. It enables the automation of network device
configurations, software provisioning, and task execution across multiple devices.
Explain the concept of "Infrastructure as Code" (IaC).
✔✔Infrastructure as Code (IaC) is the practice of managing and provisioning computing
infrastructure through machine-readable configuration files rather than physical hardware or
interactive configuration tools, allowing automation, scalability, and consistency in managing
networks.
2
,What is the significance of version control in network automation projects?
✔✔Version control is crucial in network automation because it allows developers to track
changes, collaborate with others, maintain a history of configurations, and roll back to previous
versions if needed, ensuring a structured approach to managing network automation code.
Describe how the YANG data model is used in network programmability.
✔✔YANG is a data modeling language used to define the structure and content of network
configuration and state data. It allows for standardized and extensible network device models,
making it easier to interact programmatically with network elements using NETCONF or
RESTCONF protocols.
What is the difference between synchronous and asynchronous API calls?
✔✔Synchronous API calls wait for the server to respond before proceeding with the next task,
while asynchronous API calls allow the client to continue executing tasks without waiting for the
server's response, improving efficiency in non-blocking operations.
What is the function of the NETCONF protocol in network management?
✔✔NETCONF (Network Configuration Protocol) is a protocol used to manage network devices
programmatically. It allows for configuration, state retrieval, and dynamic updates through
3
, XML-based messaging over a secure transport layer, supporting device configuration and
management.
What is the role of Docker in DevOps and network automation?
✔✔Docker is a containerization platform that allows developers to package applications and
dependencies into containers. In network automation, Docker enables the creation of isolated
environments for testing, development, and deployment of network services and automation
scripts.
How does Cisco Meraki API enhance network programmability?
✔✔The Cisco Meraki API provides programmatic access to the Meraki cloud platform, allowing
developers to automate the management of Meraki devices, networks, and security policies,
streamlining operations like network provisioning and monitoring.
What is the purpose of Continuous Integration/Continuous Deployment (CI/CD) in network
automation?
✔✔CI/CD pipelines enable automated testing, integration, and deployment of network
automation code, ensuring that new configurations and changes are tested in a controlled
environment and deployed consistently across networks without manual intervention.
