Example Scenario

Here is an example scenario that should help you get a feel for this process. Suppose an exam question has a scenario text as follows, and a network diagram as shown in Figure 1:

    A company has a network as shown in the network diagram. Switches A and B form the core, while C and D act as distribution switches. Switches A through D are already configured with working links and routing protocols.

    Switch E is added into the access layer. It is connected to switches C and D by two uplinks each. Each pair of uplinks should be joined together as a single logical link using a standards-based approach.

    Switch E needs to support two distinct groups of users in the Accounting and Engineering departments, to be placed on VLAN 10 and 20, respectively. Each VLAN needs to have a highly available gateway address in the distribution layer, using the .1 address in the appropriate subnet. The network should be configured such that the Accounting users normally pass over the link between switches C and E, while Engineering users pass over the link between D and E.

    Do not change the routing configuration on switches A, B, C, or D, other than to advertise the new Accounting and Engineering subnets. Make sure that all uplinks are functioning and that users in the Accounting and Engineering subnets can ping the server located in the data center.
