Exam Topics Covered:

1. Architecture:

• Enterprise Network Design: Understand Tier 2, Tier 3, and Fabric designs, including capacity planning.
• High Availability (HA): Implement redundancy, FHRP (First Hop Redundancy Protocols), and SSO (Single Sign-On) for network resilience.
• WLAN Deployment: Analyze various wireless deployment models (centralized, distributed, controller-less, controller-based, cloud, remote branch) and location services.
• On-Premises vs. Cloud: Differentiate between on-premises and cloud infrastructure deployments.
• Cisco SD-WAN: Learn the working principles of Cisco SD-WAN, including control and data plane elements, and compare it to traditional WAN solutions.
• Cisco SD-Access: Understand Cisco SD-Access, its control and data plane elements, and how it integrates with traditional campus networks.
• Quality of Service (QoS): Implement QoS for both wired and wireless networks, including QoS components and policy configuration.
• Switching Mechanisms: Differentiate between hardware and software switching, including CEF (Cisco Express Forwarding), MAC address tables, and TCAM (Ternary Content Addressable Memory), and FIB/RIB (Forwarding Information Base/Routing Information Base).

2. Virtualization:

• Device Virtualization: Explore hypervisor types (Type 1 & 2) and virtual machines.
• Data Path Virtualization: Configure and verify VRF (Virtual Routing and Forwarding), GRE (Generic Routing Encapsulation), and IPsec tunneling.
• Network Virtualization: Understand concepts like LISP (Locator/ID Separation Protocol) and VXLAN (Virtual Extensible LAN).

3. Infrastructure:

• Layer 2: Troubleshoot 802.1Q trunking and EtherChannel protocols. Configure and verify Spanning Tree Protocols (RSTP & MST).
• Layer 3: Compare EIGRP and OSPF routing protocols (advanced distance vector vs. link-state). Configure and verify OSPF environments (multiple areas, summarization, filtering). Configure eBGP (External Border Gateway Protocol) between directly connected neighbors.
• Wireless: Describe Layer 1 concepts (RF power, RSSI, SNR, interference). Understand AP modes, antenna types, AP discovery/join processes, and Layer 2/Layer 3 roaming principles. Troubleshoot WLAN configurations and client connectivity.
• IP Services: Describe NTP (Network Time Protocol), configure NAT/PAT (Network Address Translation/Port Address Translation), configure HSRP/VRRP (Hot Standby Router Protocol/Virtual Router Redundancy Protocol) for first hop redundancy, and understand multicast protocols (PIM/IGMP).

4. Network Assurance:

• Network Troubleshooting: Utilize tools like debugs, trace route, ping, SNMP, and syslog to diagnose network problems.
• Device Monitoring: Configure and verify syslog for remote logging.
• NetFlow & Flexible NetFlow: Configure and verify NetFlow and Flexible NetFlow for network traffic analysis.
• SPAN/RSPAN/ERSPAN: Configure and verify port mirroring for network monitoring.
• IP SLA: Configure and verify IP SLA (IP Service Level Agreements) for proactive network monitoring.
• Cisco DNA Center: Understand workflows for network configuration, monitoring, and management using Cisco DNA Center.
• NETCONF & RESTCONF: Configure and verify NETCONF and RESTCONF for network management.

5. Security:

• Device Access Control: Configure and verify lines and password protection, authentication, and authorization using AAA (Authentication, Authorization, and Accounting).
• **Infrastructure Security
