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).

The Cisco IOS assessment is designed to evaluate the knowledge and skills of a candidate in using Cisco’s Internetwork Operating System (IOS). This test is essential when hiring for positions that require Cisco IOS knowledge, such as network administrators, network engineers, and other related roles.

The assessment covers various sub-skills such as configuring and verifying routing protocols, implementing network security, working with LAN switching technologies, troubleshooting common network issues, and more. It is crucial to assess these skills as they demonstrate the candidate’s ability to manage and maintain networks, identify network issues, and implement appropriate solutions.

The Cisco IOS assessment is a reliable way to identify individuals who can operate and maintain network devices such as routers and switches. Candidates who perform well on this test are competent in configuring and troubleshooting network issues, possess critical thinking skills, and have a solid understanding of Cisco IOS. The test can help hiring managers to identify and select the best-fit candidates for network administration and engineering roles.

Who is this test for?

The Cisco IOS certification exams are relevant for network engineers and IT professionals who work with Cisco routers and switches and want to validate their skills and knowledge of Cisco's Internetwork Operating System (IOS). The certification exams cover topics such as configuration, maintenance, troubleshooting, and security of Cisco IOS-based networks. These exams are suitable for both entry-level and experienced professionals and validate the ability to install, configure, and troubleshoot Cisco IOS-based networks.
