Which two describe the access layer in a three-tier network?

The access layer is where end devices, such as computers, printers, and wireless access points (WAPs), connect to the network. Therefore, a physical connection point for a LAN printer and the layer where a WAP connects are correct descriptions. The aggregation point is typically the distribution layer, which connects the access layer to the core. While redundancy is important throughout the network, "continuous redundant uptime requirements" are more characteristic of the core and distribution layers, which handle critical traffic aggregation. The boundary between Layer 2 and Layer 3 communications is also a function of the distribution layer, where routing typically occurs.
