Refer to the exhibit.
A customer wants to replace the core and aggregation layer of an existing network. Currently the network routes between the aggregation layer and core, and uses the technologies shown in the exhibit.
The customer now wants to route at the core, instead of the aggregation layer, and extend some of the same VLANs in different buildings. However, the customer cannot eliminate the aggregation layer at this point. What should the architect recommend?
The customer wants to route at the core while extending VLANs across different buildings and maintaining the existing aggregation layer. Creating a backplane stack at the aggregation layer and a VSF fabric at the core allows for flexibility in managing VLANs and routing activities. A backplane stack at the aggregation layer provides high availability and resilient network topology, and the VSF fabric at the core facilitates efficient routing and VLAN management across the buildings. This approach aligns with the requirement to enhance network topology without eliminating the aggregation layer.
A - is correct .. backplane stacking cannot be extended across buildings...
A is correct. Check Activity 6: Recommended VLANs for new network and Activity 7.3: Wired redundancy
