The CCNA 2 v7.0 Case Study – Rev B successfully mirrors real-world networking challenges, requiring the integration of switching, routing, and security concepts. By implementing VLANs, trunking with a secure native VLAN, router-on-a-stick inter-VLAN routing, DHCP, static routing, and SSH, a network engineer builds a robust and manageable infrastructure. The case study emphasizes not just configuration but also verification and troubleshooting—essential skills for any networking professional. Ultimately, mastering these tasks prepares students for both the CCNA certification exam and practical network administration roles.
The CCNA-2v7.0 Case Study (Rev B) requires configuring a multi-site network for the Carl I. Samson Company (C.I.S. Co) following an acquisition, focusing on integrating Bangor, Phoenix, and Chicago locations. The project mandates implementing IPv4/IPv6 addressing, static routing, VLANs, switchport security, and DHCP services across the infrastructure. Detailed project requirements can be found at Course Hero.

It looks like you’re looking for a proper guide for the CCNA v7.0 (2.7.0) Case Study – Revision B.
First, a quick clarification:
The official Cisco NetAcad curriculum for CCNA 2 v7.0 (Switching, Routing, and Wireless Essentials) includes several Case Studies depending on the instructor or region — but the most common “Rev B” case study focuses on multi-switch configuration, VLANs, trunking, STP, EtherChannel, and inter-VLAN routing, often using Packet Tracer.
Below is a structured guide to complete the standard CCNA 2 v7.0 Revision B Case Study successfully.
For management security, the case study mandates replacing Telnet with SSH. Steps include:
SSH ensures that all remote management traffic, including login credentials and commands, is encrypted. Verification involves establishing an SSH session from a PC using PuTTY or the ssh -l username router-ip command. ccna-2v7.0 case study -rev b-

The CCNA-2v7.0 Case Study (Rev B) is a comprehensive practical assessment within the Cisco Networking Academy "Switching, Routing, and Wireless Essentials" (SRWE) curriculum. It simulates a real-world merger scenario involving the Carl I. Samson Company (C.I.S. Co), which has expanded its Bangor, Maine headquarters by acquiring "Big-Corp" offices in Phoenix and Chicago.
This case study challenges students to integrate multiple core networking concepts into a single, cohesive infrastructure using both IPv4 and IPv6. Core Objectives and Requirements
The Rev B assessment focuses on several key technological pillars of the SRWE course:
Static Routing: Implementing primary and backup (floating) static routes for both IPv4 and IPv6 to ensure connectivity between geographic sites.
VLANs and Inter-VLAN Routing: Organizing local traffic into segments and configuring "Router-on-a-Stick" or Layer 3 switch SVIs for communication.
Switch Security: Applying best practices like port security, disabling unused ports, and configuring encrypted management access via SSH.
DHCP Services: Configuring routers to act as DHCPv4 and DHCPv6 servers to automate host addressing.
WLAN and Redundancy: Setting up Wireless LANs and ensuring network stability through EtherChannel and Spanning Tree Protocol (STP). Phase-by-Phase Implementation 1. IP Addressing and VLAN Design
In the initial phase, you must develop an addressing scheme based on specific user requirements for each site.
Phoenix (PHX): Typically requires sub-interfacing on the Phoenix router to support multiple VLANs (e.g., VLAN 120).
Chicago (CHG): Often acts as a central hub for specific services like DHCP.
Bangor (BAN): The headquarters router, frequently used to handle IPv6 DHCP pools (e.g., "DHCP-DNS"). 2. Basic Device Configuration
Security is a priority from the start. On all routers and switches (like CHG-RTR, PHX-SW-1, and BAN-RTR), you must: The CCNA 2 v7
Secure the IOS: Encrypt all passwords, set a minimum password length (often 10 characters), and disable IP domain lookups.
Management Access: Configure a domain name (e.g., cisco.com), generate 1024-bit RSA keys, and enable SSH version 2 on VTY lines.
Brute-Force Protection: Use commands to block login attempts for a specified period (e.g., 1 minute) after 3 failures in 60 seconds. 3. Advanced Layer 2 and Layer 3 Features

. It simulates a real-world scenario where a company (often identified as the Carl I. Samson Company or C.I.S. Co) has acquired another business with multiple locations, requiring a unified, secure network infrastructure. Core Objectives & Scenario
The assessment focuses on designing and implementing a multi-site network (e.g., Bangor, Phoenix, and Chicago) using static routing IPv4 and IPv6 addressing. Key technical areas covered include: Layer 2 Security & Redundancy:
Configuring VLANs, Trunking, Spanning Tree Protocol (STP), and EtherChannel. IP Services:
Implementing DHCPv4/DHCPv6 and configuring wireless settings for remote or home office segments. Routing Operations:
Establishing connectivity through static and default routes, including floating static routes for redundancy. Network Security:
Hardening devices with SSH, port security, and encrypted passwords. ITExamAnswers Implementation Phases 1. Physical & Basic Configuration
Devices must be properly placed in the equipment rack and connected via appropriate cabling. Hostname & Banners: Assign unique names (e.g., ) and configure "Message of the Day" (MOTD) banners. Management Security:
Disable IP domain lookups, encrypt all plain-text passwords using service password encryption , and set a minimum password length. SSH Access: For management security, the case study mandates replacing
Generate RSA keys (1024-bit modulus), configure local user databases, and enable SSH on VTY lines for secure remote management. Course Hero 2. VLANs and Inter-VLAN Routing Segmentation:
Create and name VLANs according to the provided addressing table.
Configure 802.1Q trunks between switches, ensuring the native VLAN matches on both ends (often VLAN 77). Router-on-a-Stick:
Configure sub-interfaces on the central router to act as the default gateway for each VLAN. ITExamAnswers 3. Static Routing & Redundancy IPv4 & IPv6 Static Routes:
Manually define paths between site summaries (e.g., Phoenix and Chicago summaries) using exit interfaces or next-hop addresses. Default Routes:
Configure a "gateway of last resort" (0.0.0.0/0 or ::/0) pointing toward the ISP or Border Router. Floating Static Routes: Create backup paths by assigning a higher administrative distance (e.g., >90 for EIGRP backups) to the static route. 4. Dynamic Addressing (DHCP) Exclusions:
Reserve specific IP ranges (e.g., .1 to .15) for static assignments to ensure they are not handed out by the DHCP server. Pool Configuration:
Create pools with defined network ranges, default gateways, and DNS server addresses. DHCP Relay: ip helper-address
command on SVIs or sub-interfaces to forward DHCP requests to a central server. ITExamAnswers 5. Switch & Wireless Security
Based on the typical structure of Cisco Networking Academy (NetAcad) coursework, "CCNA 2 v7.0 Case Study - Rev B" usually refers to the "Design and Build a Small Network" cumulative project.
This project often involves a Packet Tracer activity where students must design an IP addressing scheme, configure routers and switches, and implement security policies.
