RCNI

The Ruckus RCNI (Ruckus Certified Network Infrastructure) exam focuses on validating a candidate's knowledge and skills in deploying and managing Ruckus Wireless networks. While the exact content changes slightly over time, the main points generally revolve around these key areas:

• Ruckus Wireless Fundamentals: Expect questions covering basic wireless concepts like 802.11 protocols (a/b/g/n/ac/ax), frequency bands (2.4GHz and 5GHz), channel selection, and the differences between various wireless technologies. Understanding concepts like MIMO, OFDMA, and MU-MIMO is crucial.

• Ruckus Product Portfolio: The exam tests your familiarity with Ruckus's various access points (APs), switches, and controllers. You should be able to identify different AP models, understand their features and capabilities, and know which products are suitable for specific deployment scenarios. This includes understanding the differences between indoor and outdoor APs and their respective features.

• Wireless Site Surveys and Planning: A significant portion of the exam focuses on the process of designing and planning a wireless network. This includes understanding site survey techniques, RF propagation, interference mitigation strategies, and capacity planning. You'll need to know how to choose the right AP placement and configurations to optimize performance.

• Ruckus Wireless Management: This section covers how to manage and monitor Ruckus wireless networks using the Ruckus management tools (likely ZoneDirector or Cloud Wi-Fi). Expect questions on configuration, troubleshooting, monitoring performance metrics (signal strength, throughput, roaming), and security settings.

• Wireless Security: A strong understanding of wireless security protocols and best practices is essential. This includes knowledge of WPA2/3 encryption, 802.1X authentication, and various security features provided by Ruckus APs and controllers.

• Troubleshooting: The ability to diagnose and resolve common wireless network problems is a key skill tested in the exam. You'll be presented with scenarios and asked to identify the root cause and propose solutions.

• Deployment Strategies: This includes understanding different deployment models, such as controller-based and cloud-managed solutions, and the advantages and disadvantages of each.

In short, the RCNI exam assesses your practical knowledge and ability to design, deploy, manage, and troubleshoot Ruckus wireless networks effectively. It's a practical, hands-on focused exam that goes beyond just theoretical knowledge. Refer to Ruckus's official documentation and study materials for the most up-to-date and accurate information.
