The is a comprehensive hands-on network integration project featured in the Cisco Networking Academy Switching, Routing, and Wireless Essentials (SRWE) curriculum. This case study serves as a capstone evaluation where students must design, implement, secure, and troubleshoot a multi-site corporate network topology using Cisco Packet Tracer . The core business scenario typically involves a primary enterprise (such as the Carl I. Samson Company based in Bangor, Maine) that has recently acquired an external entity ("Big-Corp") with branch locations in major metropolitan hubs like Phoenix, AZ, and Chicago, IL.

Completing the configuration is only half the battle. The CCNA-2v7.0 Case Study -Rev B- includes specific verification questions (e.g., "Can PC-A ping the server?"). You must demonstrate functional connectivity. ccna-2v7.0 case study -rev b-
Before touching a keyboard, you must understand the architecture. The Rev B case study typically presents a :
Configure all inter-switch links as trunks. Explicitly define the native VLAN to prevent VLAN hopping attacks:
With the subnets defined, you must configure the switching fabric to segment traffic using 802.1Q encapsulation. 1. VLAN Creation and Port Assignment Configure all access switches to host the end devices. # Default outward routing towards the ISP Border
: Configure ports connecting switches (and switches to routers for Router-on-a-Stick) as 802.1Q trunks .
: Disable all unused ports with the shutdown command and move them to a "Black Hole" VLAN (e.g., VLAN 999). 4. Configure DHCP and Wireless Enable automatic addressing and wireless connectivity.
Virtual LANs (VLANs) are used to segment a physical network into smaller, isolated broadcast domains. You will be tasked with creating multiple VLANs, assigning switch ports to them, and configuring between switches to carry traffic from multiple VLANs across a single link. The core business scenario typically involves a primary
For those preparing for the 200-301 CCNA exam or completing this case study, several platforms provide guided walkthroughs and lab files:
Revision B places heavy emphasis on securing infrastructure devices from unauthorized access. 1. Basic Switch and Router Hardening
