A few sample challenges are:

CCNA Challenge 1 Click here - D1. In this demo the basic details of the routers, such as for the hostname, domain-name, E0, along with a hosts table.

CCNA Challenge 2 Click here - D2. In this demo the basic details of the routers, such as for the serial ports (S0 and S1), including the setting of the carrier delay parameter, and to enable the ports.

CCNA Challenge 3 Click here - D3. In this demo the details of username and password is defined, along the privileged and executive passwords.

CCNA Challenge 4 Click here - D4. In this demo defines the status of the interface ports.

CCNA Challenge 5 Click here - D5. In this demo defines hostnames, banners and enabling the HTTP server.

CCNA Challenge 6 Click here - D6. In this demo defines enables the RIP routing protocol, and defines the networks which will receive routing tables. Along with this CDP is enabled on E0, and subnet-zero address can be used, along with a classless IP scheme.

CCNA Challenge 7 Click here - D7. In this demo defines logging parameters, including the logging server, and the level of the logging (such as alerts severity=1, critical severity=2, debugging severity=7, emergencies severity=0, errors severity=3, informational severity=6, notifications severity=5, and warnings severity=4). It also shows the definition of the HTTP server parameter, such as for the HTTP port and the maximum number of connections.

CCNA Challenge 8 Click here - D8. In this demo the details of the CDP are defined, such as enabling it on a port, and the holddown timer. It also contains a TELNET login definition.

CCNA Challenge 9 Click here - D9. In this demo the details of the SNMP server are defined for the router. This includes defining the community name, the location, the SNMP logging server, the chassis ID and the enabling of traps.

CCNA Challenge 10 Click here - D10. In this demo the details of the Ethernet ports, such as for duplex setting, description, and so on.

CCNA Challenge 11 Click here - D11. In this demo the details of the S0 and S1 ports are defined, including the authentication (such as PAP or CHAP), the encapsulation (such as PPP), the clock rate, the bandwidth, the speed, and so on.

CCNA Challenge 12 Click here - D12. In this demo the details of the hosts table, and other details such as the default-gateway.

CCNA Challenge 13 Click here - D13. In this demo the details of the console and TELNET settings are defined. This include timeouts, such as the executive timeout, synchronous login, and the maximum number of sessions.
