Which of the following layers of the network architecture will you use to bring in this change to your network? The aggregation layer The core layer Correct. The core layer consists of highly efficient multilayer switches or routers that support the network's backbone traffic. Typically, no filtering or routing is performed at this layer so as to minimize the processing required of these switches. Surprisingly, this layer is considered the simplest layer and doesn't need switches with lots of ports. These switches simply need to pass traffic in and out of a few backbone ports as quickly as possible. The access layer The distribution layer
