What Should the Plan Include?
Whew! That scenario covers plenty of ground, and it’s really just one question on the exam! Notice that the scenario didn’t really specify any switch features or protocols to be used. Instead, you have to put on your thinking cap and develop an implementation planfast! Remember that the exam clock is ticking. Your plan should include the following things:
- Create VLANs: VLAN 10 for Accounting and VLAN 20 for Engineering
- VLAN extent: The VLANs should exist on Switch E where the users live, and also on C and D where the gateways and routing protocols live.
- EtherChannels: Bundle one pair of uplinks between C and E and another pair between D and E. For a standards-based EtherChannel, use LACP.
- Trunks: VLANs 10 and 20 will need to be carried between switches C and E and between D and E.
- Layer 3 interfaces: You’ll need an interface vlan10 and an interface vlan20 to provide Layer 3 connectivity for the user subnets. Those will be configured on switches C and D.
- HSRP: To get highly available gateways on both VLANs 10 and 20, you’ll need to configure two different HSRP groups.
- HSRP load balancing: The two user groups need to normally pass over different uplinks. You’ll need to tune the HSRP priorities so that the gateways are split across the two distribution switches.
- Routing: You will need to add the new subnets into the network commands for the preconfigured routing protocols on switches C and D.
