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. ccna-2v7.0 case study -rev b-
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:
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

Solved CCNA-2v7.0 Case Study (Rev B) Static Routes, VLANs
CCNA-2 v7.0 Case Study (Revision B) is a comprehensive capstone project within the Switching, Routing, and Wireless Essentials (SRWE)
course. This particular scenario typically revolves around the Carl I. Samson Company (C.I.S. Co)
, a firm based in Bangor, Maine, that has recently acquired a corporation with branch offices in Phoenix, AZ, and Chicago, IL. The CCNA-2v7
The objective is to design, implement, and secure a multi-site network using a combination of IPv4 and IPv6
static routing until a permanent dynamic routing solution is decided. Core Phases of the Revision B Case Study
The project is generally divided into distinct phases that test your ability to build a functional and secure enterprise network. 1. IP Addressing and VLAN Design
You are tasked with creating a logical addressing scheme to support the different branches. VLAN Implementation
: Configuring multiple VLANs to segment traffic between departments (e.g., Management, Sales, Guest). Subnetting
: Applying IPv4 VLSM and IPv6 prefix assignments to maximize address efficiency. Inter-VLAN Routing Router-on-a-Stick
or Layer 3 switch configurations to enable communication between these segments. 2. Basic Device Configuration & Security
Before advanced features are added, you must harden each network device: Initial Settings
: Setting hostnames, encrypting all plain-text passwords, and configuring a "Banner Motd" to warn unauthorized users. SSH Access : Disabling insecure Telnet and configuring SSH Version 2 with a local username (e.g., ) and a 1024-bit RSA key for remote management. Login Security
: Implementing "block-for" commands to prevent brute-force attacks (e.g., disabling login for 1 minute after 3 failed attempts within 60 seconds). 3. Advanced Switching and Routing Mastering the CCNA-2v7
This phase focuses on redundancy and reaching remote networks:
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.
Below is a draft for a professional social media post (suitable for LinkedIn or a study group) sharing this resource, followed by a brief study guide for the concepts involved.
Issue: PCs in VLAN 10 cannot ping VLAN 20 gateway.
Cause: Trunk not configured on switch port connected to R1.
Fix: Added switchport mode trunk and allowed VLANs.
Issue: OSPF not forming neighbor between R2 and R3.
Cause: Mismatched hello/dead intervals or MTU.
Fix: Set ip ospf hello-interval 10 on both sides.
This document is a concise, complete write-up of a typical CCNA 2 v7.0 Case Study — Rev B. It presents the scenario, network topology, device addressing and configuration requirements, objectives, step-by-step tasks, verification steps, troubleshooting hints, and grading/checklist items. Use this as a study guide or template for practicing routing and switching, OSPF, access control, inter-VLAN routing, DHCP, NAT, and basic network troubleshooting.
PCs in VLAN 10 → gateway 192.168.10.1
VLAN 20 → gateway 192.168.20.1
VLAN 99 → management.
The modern enterprise relies on networks that are not only functional but also scalable, secure, and efficiently segmented. The CCNA 2 v7.0 Case Study – Rev B provides a practical scenario where a network engineer must design, configure, and verify a multi-switch, multi-router environment. This essay outlines the key implementation tasks, including VLAN segmentation, trunking, inter-VLAN routing, DHCP configuration, and remote management security, while highlighting best practices and verification strategies.
