Ccna-2v7.0 — Case Study -rev B-

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.

Solved CCNA-2v7.0 Case Study (Rev B) Static Routes, VLANs

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

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:

Secure the IOS: Encrypt all passwords, set a minimum password length (often 10 characters), and disable IP domain lookups. The CCNA 2 v7

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

This assumes a typical scenario where you are given a network topology with multiple routers, switches, VLANs, static/dynamic routing, ACLs, NAT, and DHCP.
Adjust the IP addressing and device names to match your specific case study details.

A small company, Clearview Media, has acquired a second office. You are assigned as the network engineer to design, implement, and verify the new branch network and ensure connectivity to the corporate headquarters via a serial WAN link. The network must support three departments (Sales, Engineering, and HR), provide secure access to printers and servers, and allow remote administration from headquarters. The network should be segmented using VLANs, use inter-VLAN routing on a router-on-a-stick, implement OSPF for dynamic routing with HQ, provide NAT for Internet access, secure management via SSH and access lists, and supply DHCP for hosts.

One of the most time-consuming parts of the Rev B case study is configuring DHCP for all VLANs. The case study usually prohibits using a separate server; R1 or R2 must act as the DHCP server.

To carry multiple VLANs between switches, trunk links must be configured using IEEE 802.1Q encapsulation. The case study typically requires trunking on the interfaces connecting the two switches and between the switch and the router.

A critical best practice reinforced in Rev B is the modification of the native VLAN from the default VLAN 1 to an unused VLAN (e.g., VLAN 99) to prevent VLAN hopping attacks. The command switchport trunk native vlan 99 is applied. Additionally, switchport mode trunk and explicitly allowed VLANs using switchport trunk allowed vlan add ... ensure only required traffic traverses the trunk.

Set primary/secondary root for different VLANs (load balancing).

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.
