LAN Switching Technologies: Understand concepts related to VLANs, VTP (VLAN Trunking Protocol), STP (Spanning Tree Protocol), EtherChannel, and inter-VLAN routing.

IP Routing Technologies: Study dynamic routing protocols like OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol), along with static routing and route redistribution.

IP Services: Familiarize yourself with DHCP (Dynamic Host Configuration Protocol), NAT (Network Address Translation), and ACLs (Access Control Lists) for controlling network traffic.

Troubleshooting: Learn how to troubleshoot common networking issues related to connectivity, VLANs, routing, and switching.

WAN Technologies: Get familiar with WAN technologies like PPP (Point-to-Point Protocol), HDLC (High-Level Data Link Control), and various encapsulation methods.

Infrastructure Services: Study topics such as HSRP (Hot Standby Router Protocol), SNMP (Simple Network Management Protocol), and NTP (Network Time Protocol).

Infrastructure Maintenance: Borderless Networks enable seamless collaboration among users and facilitate the efficient delivery of applications across the network. Application optimization techniques, such as caching and compression, are employed to enhance user experience and reduce network congestion.

Certification Preparation: Understand concepts related to device monitoring, device management, and firmware upgrades.
