Ccna-2v7.0 Case Study -rev B- [patched] Jun 2026

The CCNA-2 v7.0 Case Study (Rev B) acts as a capstone project for the Switching, Routing, and Wireless Essentials (SRWE) course, requiring the integration of VLANs, STP, security, and routing for the C.I.S. Co. expansion. The project necessitates configuring IPv4/IPv6, EtherChannel, and wireless LAN controllers, commonly documented in resources available on sites like Course Hero and Scribd.

Common mistake: Forgetting to set the native VLAN on both ends of the trunk. Mismatched native VLANs cause spanning-tree loops or connectivity loss.

To eliminate hardware-crushing loop storms across redundant uplinks, explicit STP configurations dictate exactly which root bridge takes priority over specific corporate VLAN traffic distributions.

All inter-switch links and router-facing switch interfaces must be converted to 802.1Q trunks. Leaving the native traffic default setting on VLAN 1 exposes the enterprise to VLAN hopping attacks. ccna-2v7.0 case study -rev b-

static routing until a permanent dynamic routing solution is decided. Core Phases of the Revision B Case Study

A core component of Rev B is optimizing a given IPv4 block (such as 192.168.10.0 /24 or a private Class B block) using Variable Length Subnet Masking (VLSM). You must allocate subnets based on host requirements, typically arranged from largest to smallest: Subnet/VLAN Name Host Requirement Subnet Mask (CIDR) /26 General corporate users VLAN 20 - Engineering /27 High-bandwidth users VLAN 30 - Management /28 Network administrators VLAN 99 - Native /28 or /29 Untagged trunk traffic Point-to-Point WAN /30 Router-to-Router links 2.
