Ccna-2v7.0 Case Study -rev B- __top__ -
In the CCNA 2 v7.0 Case Study - Rev B, a particularly interesting feature is the complex implementation of Floating Static Routes integrated with First Hop Redundancy Protocols (FHRP).
This scenario challenges you to move beyond basic static routing by configuring a secondary backup path that only appears in the routing table when the primary link fails. It specifically tests your ability to ensure high availability in a small-to-medium enterprise network. Key Technical Highlights
Floating Static Routes with IP SLA: This feature requires configuring an IP Service Level Agreement (SLA) to monitor the primary link's health. If the SLA probe fails, the floating static route—configured with a higher administrative distance—automatically takes over.
HSRP (Hot Standby Router Protocol) Integration: The case study often requires coordinating these floating routes with HSRP to provide a redundant gateway for end devices, ensuring that even if a router or link fails, the user traffic seamlessly transitions to the backup path.
Inter-VLAN Routing and Security: You must manage data flow between different VLANs while simultaneously applying Access Control Lists (ACLs) to secure the perimeter and internal segments.
Dynamic vs. Static Comparison: The case study forces a practical comparison between manual static route management and the automated discovery provided by dynamic protocols like OSPFv2, highlighting why certain environments might prefer the lower overhead of static routes despite their lack of scalability.
Case Study:

This case study assesses your skills in designing and implementing a network infrastructure using Cisco devices, as well as your ability to configure and troubleshoot network features such as VLANs and QoS. Good luck!
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.
Solved CCNA-2v7.0 Case Study (Rev B) Static Routes, VLANs
The CCNA-2 v7.0 Case Study -Rev B- is a comprehensive capstone project within the Cisco Networking Academy's Switching, Routing, and Wireless Essentials (SRWE) curriculum. It serves as a practical assessment where students must design, configure, and troubleshoot a multi-site enterprise network that reflects real-world deployment challenges. Objectives of the Case Study
The primary goal of Revision B is to validate your ability to integrate the core technologies introduced in CCNA v7.0. Key objectives include: In the CCNA 2 v7
VLAN and Trunking Implementation: Segregating traffic for security and performance using 802.1Q trunks.
Redundancy Protocols: Configuring EtherChannel for link aggregation and Spanning Tree Protocol (STP) to prevent loops.
Dynamic Addressing: Setting up DHCPv4 and DHCPv6 (Stateless/Stateful) to automate IP management.
Routing and Security: Implementing Inter-VLAN routing (Router-on-a-Stick or Layer 3 Switching) and securing the infrastructure with SSH and Port Security. Core Configuration Components
The case study typically requires a hands-on approach using Cisco Packet Tracer or physical hardware to meet the following requirements: 1. Layer 2 Redundancy and Switching
Students must ensure high availability by configuring EtherChannel (LACP) between core switches. This allows for increased bandwidth and prevents a single point of failure. Additionally, the STP Bridge Priority must be adjusted to designate specific switches as Root Bridges for different VLANs. 2. Advanced IP Services
A major focus of the Rev B version is DHCP Relay. When the DHCP server is located in a different subnet, students must configure the ip helper-address on the router interfaces to forward local broadcast requests. This ensures that clients in remote branches can still receive dynamic addressing. 3. WLAN Configuration
In line with modern enterprise needs, the study often includes the setup of a Wireless LAN Controller (WLC). This involves: Defining SSIDs with WPA2-PSK or Enterprise authentication. Mapping SSIDs to specific VLANs.
Ensuring seamless connectivity between wired and wireless clients. Troubleshooting and Best Practices
The -Rev B- designation often indicates updated security requirements or revised IP addressing schemes compared to the original version. To succeed, students should follow these Cisco-recommended practices:
Document the Topology: Always maintain an up-to-date IP address table.
Verify Step-by-Step: Use commands like show ip interface brief, show etherchannel summary, and show vlan brief after every major configuration block.
Secure Management: Always disable unused ports and use secret passwords rather than plain-text. Recommended Study Resources

Are there specific Packet Tracer instructions or configuration commands from the Case Study -Rev B- you would like me to explain further?
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.
CCNA 2 v7.0 Case Study – Revision B
Student Name: [Your Name]
Date: [Current Date]
Instructor: [Instructor Name]
3.6 NAT (if internet access simulated)
- On R1 (inside=LAN, outside=WAN):
access-list 1 permit 192.168.10.0 0.0.0.255 access-list 1 permit 192.168.20.0 0.0.0.255 ip nat inside source list 1 interface s0/0/0 overload
Understanding the Scope and Topology (Rev B)
Before touching a keyboard, you must understand the architecture. The Rev B case study typically presents a three-tier hierarchical network:
- Core Layer: A single high-end router or Layer 3 switch acting as the gateway to a simulated internet (often an ISP router).
- Distribution Layer: One or two routers (e.g., R1, R2) responsible for inter-VLAN routing, DHCP services, and access control.
- Access Layer: Multiple Layer 2 switches (e.g., S1, S2, S3) hosting end devices like PCs, printers, and a server farm.
Step 1.3: Trunk Configuration
Inter-switch links and links to the router must be trunks. Configure them as:
interface g0/1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk native vlan 99
switchport trunk allowed vlan 10,20,99
Common mistake: Forgetting to set the native VLAN on both ends of the trunk. Mismatched native VLANs cause spanning-tree loops or connectivity loss.
Step 5.2: Extended ACL (Correct approach)
R1(config)# access-list 100 deny ip 192.168.20.0 0.0.0.255 192.168.10.0 0.0.0.255
R1(config)# access-list 100 deny ip 192.168.20.0 0.0.0.255 192.168.99.0 0.0.0.255
R1(config)# access-list 100 permit ip any any
R1(config)# interface g0/0/1.20
R1(config-subif)# ip access-group 100 in
This ACL, applied inbound on the Guest subinterface, blocks Guest packets destined for Employee and Management VLANs, but permits everything else (including internet-bound traffic).
3.5 DHCP Configuration
- R1 as DHCP server for VLAN 10:
ip dhcp pool SALES network 192.168.10.0 255.255.255.0 default-router 192.168.10.1 dns-server 8.8.8.8 - Exclude static addresses:
ip dhcp excluded-address 192.168.10.1 192.168.10.10
Step 1.1: Basic Switch Hardening
For each access switch (S1, S2), apply the following:
- Set hostname, disable DNS lookup, set privileged exec password, and configure a login banner (legal warning).
- Set console and vty lines to require passwords and enable synchronization.
- Configure the management VLAN (e.g., VLAN 99) with an appropriate IP address and default gateway.
