Cisco 200-901: YANG Data Models for Network Engineers
YANG gives network automation a schema for the data a device exposes. Instead of treating configuration as an arbitrary block of CLI text,…
Read articleCisco 200-901: Secure API Authentication for Network Tools
Network APIs can expose the same authority that engineers once exercised through privileged command-line sessions, so authentication deserves the same design attention as…
Read articleCisco 200-901: Python for Network Automation with Cisco APIs
Python is effective for network automation because it can connect API calls, data transformation, validation, file handling, testing, and reporting in one readable…
Read articleCisco 200-901: NETCONF vs RESTCONF in Cisco Automation
NETCONF and RESTCONF give network software structured ways to read and change device data without scraping command-line output. On Cisco IOS XE, both…
Read articleCisco 200-901: Git Workflows for Network Automation
Git is useful in network automation because the automation itself becomes an operational asset. Python modules, Ansible playbooks, Jinja templates, inventory data, validation…
Read articleCisco 200-901: Webex and Meraki API Fundamentals
Cisco platforms expose APIs so software can read operational data and perform controlled actions without relying on browser clicks or screen scraping. Webex…
Read articleCisco 200-901: CI/CD Concepts for Network Automation
Continuous integration and continuous delivery apply software-delivery discipline to network automation artifacts such as playbooks, templates, Python code, intent models, and infrastructure definitions.…
Read articleCisco 200-901: Ansible for Cisco Network Configuration
Ansible gives network engineers a way to describe configuration tasks as repeatable automation rather than retyping command sequences on each device. The tool…
Read articleCisco 200-301: Wireless LAN Architecture
Enterprise Wi-Fi is not simply Ethernet without cables. A wireless LAN combines radio-frequency behavior, access points, controllers or cloud control, authentication, VLAN mapping,…
Read articleCisco 200-301: VLANs, Trunks, and Native VLAN Behavior
VLANs divide a switched network into separate Layer 2 broadcast domains, while trunks let several VLANs share one physical link between switches, routers,…
Read articleCisco 200-301: Troubleshooting Layer 2 and Layer 3 Connectivity
Connectivity troubleshooting becomes much faster when the engineer stops treating “the network is down” as one problem. A user flow crosses multiple layers:…
Read articleCisco 200-301: Switch Port Security and Layer 2 Protection
Layer 2 access ports sit at the edge of the network where user devices, phones, printers, access points, and unmanaged equipment connect. Because…
Read articleCisco 200-301: Static Routes and Administrative Distance
Static routing gives the administrator direct control over where a router sends traffic for a destination prefix. A sound campus and WAN topology…
Read articleCisco 200-301: Spanning Tree Root Bridge Design
Spanning Tree Protocol is often introduced as a loop-prevention mechanism, but the root bridge is what turns that mechanism into a predictable Layer…
