Which layer supports convergence for voice, wireless, and data?
- distribution
- access
- none of the above
- core
Explanation: The access layer is the specific functional area of the network where end devices, such as PCs, printers, and cameras, attach to the wired campus infrastructure. It supports the convergence of different communication services by serving as the primary connection point for IP phones (voice) and wireless access points (wireless). To facilitate this convergence, the access layer provides essential technologies like Power over Ethernet (PoE) and perpetual power to ensure voice and wireless devices remain operational during reboots. Because it must handle such a wide variety of device types and service requirements, the access layer is defined as one of the most feature-rich parts of the campus network. In modern designs like SD-Access, this layer also helps automate policy for any application across the unified wireless and wired network fabric.
