R1(config)# access-list 1 deny 192.168.20.0 0.0.0.255
R1(config)# access-list 1 permit any
But wait – that denies Guest from everything. The requirement is usually: Guest can access internet, but not internal VLANs. So you need an extended ACL.
The first critical task in the case study is dividing the broadcast domain using Virtual Local Area Networks (VLANs). VLANs improve security and reduce unnecessary traffic. Typically, Rev B specifies VLANs for different departments such as:
On each switch, VLANs are created using the vlan vlan-id command followed by a descriptive name. Access ports are then assigned to these VLANs using switchport mode access and switchport access vlan vlan-id. This segmentation ensures that broadcast traffic from Sales does not reach Operations, thereby improving performance and security.
Reserve static addresses for routers, switches, and servers.
R1(config)# ip dhcp excluded-address 192.168.10.1 192.168.10.10
R1(config)# ip dhcp excluded-address 192.168.20.1 192.168.20.5
The CCNA-2v7.0 Case Study -Rev B- is not merely a test of rote commands; it is a simulation of a network engineer’s daily workflow. By methodically working through VLAN segmentation, inter-VLAN routing, DHCP, static routing, NAT, and ACLs, you are constructing a small enterprise network from scratch.
Remember the troubleshooting mindset: start at Layer 1, verify Layer 2, and only then proceed to Layer 3 and above. Use ping, traceroute, and show commands relentlessly. If a ping fails, check the ARP table, check the routing table, and verify ACLs.
Mastering this case study will leave you with a portfolio-worthy configuration and the confidence to move on to the third CCNA v7.0 course (ENSA) and, ultimately, the CCNA certification exam. Good luck, and happy configuring.
Next Steps: After completing Rev B, review your configuration against the official scoring rubric. If possible, have a peer review your ACL logic. Then, document every interface IP, VLAN mapping, and route in a network diagram – that documentation is a habit of successful professionals.

The air in the Evergreen Network Operations Center (NOC) was thick with the hum of server fans and the smell of slightly over-steeped coffee.
, a junior network engineer, stared at the printed packet on his desk: "CCNA-2v7.0 Case Study -Rev B-"
. This wasn't just a lab; it was the final blueprint for the Oakhaven University
campus expansion, and the "Rev B" meant the stakes—and the complexity—had just been raised. 1. The Challenge: A Network Divided
Oakhaven was growing. The mandate was clear: connect the new Science Wing Student Union to the existing Main Campus
core. But there were complications. The Dean insisted on total isolation for the research data, while the Student Union needed open Wi-Fi that wouldn't bog down the registrar’s office. Alex looked at the topology. It was a classic "Rev B" mess: VLANs 10, 20, and 99 were already saturated. The new wing required DHCP relay because the central server was three hops away. Inter-VLAN routing had to be handled by a new Layer 3 switch , replacing the aging "Router-on-a-Stick" setup. 2. The Implementation: Trunking and Tensions
"Alright, let's light it up," Alex muttered, fingers flying across the mechanical keyboard. First came the trunks. He configured the 802.1Q encapsulation
, ensuring the native VLANs matched across all switches to avoid the dreaded CDP mismatch errors. He watched the console amber lights turn to a steady, rhythmic green. But then, the Science Wing went dark. "STP," Alex realized. The Spanning Tree Protocol
had detected a loop in the redundant links he'd just patched in. Because he hadn't set the Bridge Priority
, the oldest, slowest switch in the basement had elected itself the "Root Bridge," bottlenecking the entire 10Gbps fiber backbone. With a few commands— spanning-tree vlan 1-100 root primary
—he reclaimed control, forcing the core switch to take its rightful place at the center of the universe. 3. The Security Breach R1(config)# access-list 1 deny 192
Just as the "Rev B" requirements dictated, Alex had to implement Port Security
. He restricted the Science Wing wall jacks to a single "Sticky" MAC address. Suddenly, an alert flashed: Security Violation on FastEthernet 0/24
A researcher had tried to plug in a rogue wireless access point to get better signal for his tablet. The port had instantly Error-Disabled
. Alex didn't just reset it; he used it as a "teachable moment" about the importance of the Access Control Lists (ACLs)
he was currently writing to keep the research data behind a virtual fortress. 4. The Final Ping By 2:00 AM, the last piece of the Case Study was in place: Static Routing for the backup link and for the primary.
Alex typed the command that every engineer holds their breath for: ping 192.168.10.1
The exclamation points marched across the screen. Success. The Science Wing could talk to the Data Center; the Student Union was isolated but online; and the "Rev B" revisions were fully satisfied. He saved the configuration— copy run start
—and listened to the hum of the NOC, which now sounded a lot less like a threat and a lot more like a job well done. of this case study, such as DHCP configuration VLAN routing

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.
Since devices in different VLANs need to communicate (e.g., Management accessing a server in Operations), routing between VLANs is necessary. The case study implements a “Router-on-a-Stick” topology where the router’s single physical interface is divided into logical subinterfaces.
Configuration on the router involves:
Each subinterface serves as the default gateway for its respective VLAN. Verification includes show ip route and pinging between hosts on different VLANs.
The Cisco Certified Network Associate (CCNA) curriculum is the gold standard for entry-level networking proficiency. Within the second course of the v7.0 series, Switching, Routing, and Wireless Essentials (SRWE), students encounter a pivotal assessment: the CCNA-2v7.0 Case Study -Rev B- . This is not merely another quiz; it is a comprehensive, scenario-based exam that simulates real-world network design, configuration, and troubleshooting. But wait – that denies Guest from everything
Unlike standard multiple-choice tests, Rev B of this case study demands that students integrate multiple competencies: VLAN segmentation, DHCP configuration, static and dynamic routing, access control lists (ACLs), and network address translation (NAT). Many students find this case study challenging because it requires applying theoretical knowledge to a dynamic topology.
This article provides a complete breakdown of the CCNA-2v7.0 Case Study -Rev B-. We will cover the expected topology, typical objectives, configuration steps, verification commands, and common pitfalls. By the end, you will have a strategic roadmap to not only complete the case study but also understand the "why" behind each task.
