Challenge Solutions

The following are an example of challenge solutions:

Topology 2 (2 routers, 1 switch and 1 host)

Demo 1[ here ]. This uses R1(e0) at 10.0.0.4, and the host at 10.0.0.1, where the default gateway is set at 10.0.0.4.

Demo 2 [ here ]. This uses VLAN 1 on the switch (set at 10.1.1.1), and the router E0 port is set at 10.1.1.3, with the host at 10.1.1.2.

Topology 1 Completed

There are two examples of the Set Complete labs:

Demo 1 [ here ]. This involves a shutdown on the R2 E0 port.

Demo 2 [ here ]. This involves a shutdown on the R1 E0 port.

Wireless Challenge 3 [Click here - D3]. In this demo the details of the BVI port are defined, along with the radio port (D0).

Wireless Challenge 4 [Click here - D4]. In this demo the SSID details are defined. The is a new update in the Aironet for the DOT11 SSID NAME command which is defined on newer IOS versions. The simulator supports the older command where it is defined within the radio interface.

Wireless Challenge 5 [Click here - D5]. In this demo, a username and password is defined (which can be used to login, and for local authentication). It also enables the HTTP server, and defines some IP address format settings.

Wireless Challenge 6 [Click here - D6]. In this demo, more detail on the D0 port is defined, along with SSID details. This includes defining the channel used.

Wireless Challenge 7 [Click here - D7]. In this demo, more detail on the D0 port is defined, along with SSID details. This includes antenna diversity.

Wireless Tutorial 1 [Wireless Tutorial 1]. In this tutorial the user setups up the key configuration parameters of the access point.

PIX/ASA Challenges

PIX/ASA Challenge 1 [Click here (V6)- P1][Click here (V7)- P1]. In this demo the basic details of the PIX/ASA device is defined for both V 6.x and V7.x. With 7.x the interfaces are more structured, but some certification still focuses on V6.x. The details for the E0 interface are IP address, and IP subnet.

PIX/ASA Challenge 2 [Click here (V6)- P2][Click here (V7)- P2]. In this demo the basic details of the PIX/ASA device is defined for both V 6.x and V7.x. With 7.x the interfaces are more structured, but some certification still focuses on V6.x. The details for the E1 and E2 interfaces are IP address, and IP subnet.

Fun Activity 5 [Click here - A5]. In this demo we meet the amazing Diffie-Hellman method which was developed by the great Wittfield Diffie. It shows that two users can agree on two numbers (G and n), and then generate their own random numbers, and perform a calcuation. The result of this calculation is send to the other party, and, after another calculation they end up with the same secret key. Diffie-Hellman is the basis for many areas of security, including VPNs, on-line shopping, nd so on.

Fun Activity 8 [Click here - A8]. In this demo we match up the IP address with its classification.
