Skills measured
Configuration & CLI Proficiency
This skill evaluates a candidate’s fluency in using the Cisco IOS command-line interface (CLI) for configuring and managing network devices. It covers basic to advanced command usage, modes of operation, and syntax accuracy. CLI proficiency is foundational to administering Cisco routers and switches and is essential for day-to-day configuration, troubleshooting, and network tuning. This skill ensures users are equipped to interact confidently with IOS environments without relying on GUIs or automated scripts.
Security Features & Access Control
This area assesses the ability to implement Cisco IOS security mechanisms including AAA (Authentication, Authorization, Accounting), port security, ACLs (Access Control Lists), and secure management protocols like SSH. It validates understanding of how to control device access, segment traffic, and protect against unauthorized intrusions. Given rising cyber threats, this skill is vital for ensuring the network perimeter and control planes are resilient and compliant with enterprise security policies.
Routing Configuration & Management
This skill focuses on configuring and managing routing protocols such as OSPF, EIGRP, RIP, and static routing within Cisco IOS. It includes tasks like route summarization, redistribution, route filtering, and administrative distance tuning. Effective routing ensures optimized traffic paths, network scalability, and efficient fault tolerance — making this a critical skill for anyone managing dynamic or enterprise-grade networks.
Monitoring, Troubleshooting & Interfaces
This skill measures the candidate's ability to diagnose and resolve IOS-based network issues using tools such as ping, traceroute, show, and debug commands. It also includes interface configuration, verification, and counters (e.g., input/output errors). The ability to monitor device health and interface performance is vital for maintaining uptime, quickly isolating faults, and ensuring service quality in real-world environments.
Network Services & Protocols
This section tests the configuration and understanding of essential services like DHCP, NAT, NTP, SNMP, and DNS forwarding in IOS. These protocols enable critical backend services and interoperability across networks. Mastery of these services ensures devices can dynamically allocate IPs, sync time, resolve names, and securely communicate network data — fundamental for any enterprise or branch network.
Virtualization & Cloud Integration
This skill evaluates knowledge of features such as VRF (Virtual Routing and Forwarding), GRE tunnels, VPNs, and cloud gateway configurations within IOS environments. As enterprises migrate to hybrid-cloud models, understanding how IOS interacts with virtualized infrastructure and external services is crucial. This area ensures candidates can bridge on-prem and cloud-based networks while maintaining segmentation, security, and performance.
IOS Fundamentals
This foundational skill area covers the structure, purpose, and operational logic of Cisco IOS. It includes understanding startup configurations, IOS boot process, file systems, configuration registers, and licensing. It ensures candidates are grounded in the underlying architecture of IOS, which is essential for effective administration, maintenance, and system recovery procedures.
Switching Technologies
This skill evaluates proficiency in configuring VLANs, trunking (802.1Q), STP (Spanning Tree Protocol), EtherChannel, and VTP. Switching forms the backbone of LAN environments, and misconfiguration can result in loops, outages, or segmentation issues. This area is key to verifying a candidate’s ability to design and maintain resilient and scalable Layer 2 topologies.
High Availability & Redundancy
This area focuses on features such as HSRP, VRRP, GLBP, port fast, root guard, and device redundancy strategies. These mechanisms are crucial in ensuring uninterrupted services during failures or maintenance. Candidates are tested on their ability to implement resilient designs that minimize downtime and maintain continuous availability of core network services.
IOS-XE & Software-Defined Features
This skill covers the advanced features of IOS-XE, including modularity, APIs, SD-WAN, and service containers. As networks evolve into software-defined models, this area ensures readiness to deploy next-gen architectures using programmable and service-rich platforms. Understanding IOS-XE's architecture and capabilities is essential for operating modern Cisco routers and Catalyst platforms.
Version Enhancements & Feature Sets
This area examines knowledge of version-specific features, bug fixes, command deprecations, and licensing changes across IOS and IOS-XE releases. It ensures candidates can make informed decisions on upgrades, compatibility, and feature selection for their environments. Keeping pace with enhancements helps avoid regressions and enables leveraging new efficiencies.
Automation & Programmability
This skill evaluates the ability to use CLI-based automation (e.g., EEM), Python, RESTCONF/NETCONF, and scripting to automate configuration and monitoring tasks. It reflects modern network practices aimed at reducing manual effort, minimizing error, and increasing scalability. Candidates skilled here can drive operational efficiency and integrate with broader DevNet or CI/CD pipelines.
Use of the CISCO IOS Test
The Cisco IOS assessment is designed to evaluate candidates’ knowledge and skills in the Cisco Internetwork Operating System (IOS).
