Ccna-2v7.0 Case Study -rev B- May 2026

The CCNA 2 v7.0 (Switching, Routing, and Wireless Essentials) curriculum focuses on the architecture, components, and operations of routers and switches in small networks. Developing a case study for this specific version typically involves a scenario where a business must expand its network infrastructure to support multiple LANs and secure wireless access. Scenario Overview

Port connected to router is a trunk (allow VLANs 10,20,99).

ip dhcp excluded-address 192.168.10.1 192.168.10.50
ip dhcp excluded-address 192.168.20.1 192.168.20.50
ip dhcp excluded-address 192.168.30.1 192.168.30.50

Study the given network topology and identify the devices, including routers, switches, and PCs.
Take note of the IP addresses, subnet masks, and default gateways.

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

Routers:
: Setting hostnames, encrypting all plain-text passwords, and configuring a "Banner Motd" to warn unauthorized users. SSH Access : Disabling insecure Telnet and configuring SSH Version 2 with a local username (e.g., ) and a 1024-bit RSA key for remote management. Login Security
