Infrastructure Layer 2 encompasses the troubleshooting of static and dynamic 802.1q trunking protocols to ensure proper VLAN communication across switches, as well as the configuration and troubleshooting of static and dynamic EtherChannels for link aggregation. Additionally, this section covers the configuration and verification of common Spanning Tree Protocols, including RSTP and MST, to prevent network loops and ensure optimal path selection. Layer 3 focuses on comparing the routing concepts of EIGRP and OSPF, examining their differences as advanced distance vector and link-state protocols respectively, including their load balancing capabilities, path selection mechanisms, and metric calculations. Students must configure and verify simple OSPF environments with multiple normal areas, implement summarization and filtering techniques, and understand neighbor adjacency, network types, and passive interface configurations. This layer also includes the configuration and verification of eBGP between directly connected neighbors, with emphasis on best path selection algorithms and neighbor relationship establishment. Wireless infrastructure requires understanding Layer 1 concepts such as RF power, RSSI, SNR, interference, noise, frequency bands, channels, and wireless client device capabilities to optimize network performance. Students must describe various AP modes and antenna types used in wireless deployments, understand the access point discovery and join process including discovery algorithms and WLC selection mechanisms, and explain the principles and use cases for both Layer 2 and Layer 3 roaming. Troubleshooting WLAN configuration and wireless client connectivity issues is essential for maintaining reliable wireless networks. IP Services covers the description and implementation of Network Time Protocol (NTP) for network synchronization, configuration and verification of NAT/PAT for address translation, and the configuration of first hop redundancy protocols such as HSRP and VRRP to ensure gateway availability. Additionally, this section includes the description of multicast protocols, specifically PIM and IGMP v2/v3, which enable efficient one-to-many and many-to-many communication across networks.
