Study -rev B- [better]: Ccna-2v7.0 Case

CCNA-2 v7.0 Case Study (Rev B) focuses on the "Switching, Routing, and Wireless Essentials" (SRWE) curriculum. It typically centers on a scenario where the Carl I. Samson Company (C.I.S. Co) in Maine acquires a firm called "Big-Corp" with branches in ITExamAnswers

The primary objective is to implement a unified network using static routing , and various Layer 2 security Key Case Study Components

The assignment is generally divided into phases that mirror the SRWE course modules: Phase I: IP Addressing and VLANs IPv4 & IPv6 Design

: Subnetting both protocols to accommodate multiple locations. Inter-VLAN Routing

: Implementing router-on-a-stick or SVI-based routing to allow communication between different departmental VLANs. Phase II: Infrastructure Configuration EtherChannel

: Configuring link aggregation (LACP) between switches to increase bandwidth and provide redundancy. Spanning Tree (STP)

: Ensuring a loop-free topology while maintaining redundant paths. DHCP Services

: Configuring a router or dedicated server to provide dynamic addressing for hosts. Phase III: Security and Wireless Switch Security : Applying Port Security DHCP Snooping BPDU Guard to mitigate common Layer 2 attacks. Wireless LAN (WLAN)

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

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.

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

It looks like you’re looking for a proper guide for the CCNA v7.0 (2.7.0) Case Study – Revision B.

First, a quick clarification:
The official Cisco NetAcad curriculum for CCNA 2 v7.0 (Switching, Routing, and Wireless Essentials) includes several Case Studies depending on the instructor or region — but the most common “Rev B” case study focuses on multi-switch configuration, VLANs, trunking, STP, EtherChannel, and inter-VLAN routing, often using Packet Tracer.

Below is a structured guide to complete the standard CCNA 2 v7.0 Revision B Case Study successfully.

2. Trunking and the Native VLAN

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.

7. Device Hardening and Best Practices

Additional security measures required in Rev B include:

  • Setting console and vty passwords.
  • Using exec-timeout to auto-logout idle sessions.
  • Disabling unused switch ports and placing them in a “black-hole” VLAN.
  • Configuring logging synchronous to prevent console interrupt messages.

These steps adhere to the defense-in-depth principle, reducing the attack surface of the network.

7. Sample Topology (Typical Rev B)

[PC1] --(VLAN10)-- SW1 ----(EtherChannel)---- SW2 ----(trunk)---- Router
[PC2] --(VLAN20)-- SW1                             | 
                                                   SW3 (VLAN10/20)

If you tell me exactly what is written in your case study packet (the IP scheme, VLAN numbers, number of switches), I can give you a ready-to-use configuration script for Rev B.

Step 3.1: Excluding Addresses

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

5. Troubleshooting Encountered

  • 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.

Layer 3 Verification:

  • [ ] show ip route – Default route (0.0.0.0/0) exists. Connected routes for all subinterfaces.
  • [ ] show ip dhcp binding – Clients have received IPs.
  • [ ] Ping from PC-A to R1’s subinterface → Success.
  • [ ] Ping from PC-A to PC-B (different VLAN) → Success (via router).
  • [ ] Ping from PC-B to server (Employee VLAN) → Should fail if ACL is applied correctly.
  • [ ] Ping from PC-B to 8.8.8.8 (ISP loopback) → Success.
