Verification: Use show ip interface brief to confirm subinterfaces are up/up. Then ping from PC-A (192.168.10.10) to the router’s subinterface (192.168.10.1). If that fails, check trunk allowed VLANs on the switch.
All required objectives were met:
✅ VLANs configured and trunking operational
✅ Inter-VLAN routing verified
✅ OSPF and static routes functional
✅ DHCP providing IPs to end devices
✅ NAT overload working for internet-bound traffic
✅ SSH secured with ACL
The network operates as per the case study requirements of Revision 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: ccna-2v7.0 case study -rev b-
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. interface g0/0/1
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
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. Verification: Use show ip interface brief to confirm
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.
To let both Employee and Guest VLANs reach the internet:
R1(config)# access-list 101 permit ip 192.168.10.0 0.0.0.255 any
R1(config)# access-list 101 permit ip 192.168.20.0 0.0.0.255 any
R1(config)# ip nat inside source list 101 interface g0/0/0 overload
R1(config)# interface g0/0/0
R1(config-if)# ip nat outside
R1(config)# interface g0/0/1.10
R1(config-if)# ip nat inside
R1(config)# interface g0/0/1.20
R1(config-if)# ip nat inside
Verification: From PC-B (Guest), ping 8.8.8.8. Use show ip nat translations to see dynamic entries.
Subject: 📚 Resource Share: CCNA 2 v7.0 Case Study (Rev B) - Design & Build
Body: Looking for the CCNA 2 v7.0 Case Study - Rev B materials? This is the cumulative capstone for the SRWE (Switching, Routing, and Wireless Essentials) curriculum.
It’s a critical exercise for anyone preparing for the new CCNA 200-301 exam. It moves beyond individual chapter labs and forces you to integrate skills like: 🔹 Subnetting and Addressing Schemes. 🔹 VLAN & Trunk configuration. 🔹 Inter-VLAN Routing (Router-on-a-Stick or L3 Switching). 🔹 DHCP & DNS services. 🔹 Security (Port Security, SSH, ACLs).
💡 Study Tip: Don't just look for the answer key! The value in the "Case Study" is the design phase. If you are stuck on the Packet Tracer topology, try building the addressing table manually on paper first.
