Explanation
In the hierarchical network design model, the access layer is the first layer and serves as the entry point for end-user devices to connect to the network. This layer connects user devices such as PCs, IP phones, wireless access points, printers, and scanners to the network. It facilitates the initial connection between end-user devices and the network infrastructure. The access layer also enforces security policies and provides services such as VLAN membership, port security, and Quality of Service (QoS).

Dimitris E.Jun 23, 2026B is correct, and if you have spent any time in a wiring closet you already know why. The access layer is where your end devices actually plug in, whether that is a PC, an IP phone, a printer, or a WAP. Think of it as the edge of your campus hierarchy where the user traffic first hits the network. When you do a show cdp neighbors on a distribution switch, every downstream neighbor you see is an access layer switch with users hanging off it. A is describing the core layer, C is describing a firewall or VPN concentrator function, and D is your WAN or MPLS edge, none of which belong at the access layer.
Toby R.Jun 26, 2026B is right, though I kept second-guessing myself on this one because A sounds like it could describe an access layer switch if you're thinking about intra-building links, but that is really describing distribution or backbone behavior. The access layer is strictly where your end devices, laptops, phones, printers, plug into the network, so B is the one to pick.
Imani T.Jun 26, 2026B is it, access layer is where your end devices plug in.
Grace U.Jun 26, 2026B is right, the access layer is where end devices plug in.
Priscilla G.Jun 26, 2026Domain 2.2, network hierarchy: A tempts you with speed, but the access layer connects endpoints, so B.
