Best WAN Access Technology for Small Office/Home Office Architecture

A.

For a small office/home office (SOHO) architecture, the preferred WAN access technology is broadband cable access (Option A).

Broadband cable access uses the same infrastructure as cable television to provide high-speed internet access. This technology offers high bandwidth at a lower cost compared to other WAN access technologies such as dedicated point-to-point leased lines (Option C) and Integrated Services Digital Network switching (Option D). It also allows multiple devices to connect to the internet using a single cable modem.

Frame-relay packet switching (Option B) is an older WAN technology that provides a reliable and efficient method of transmitting data over a wide area network. However, it requires a dedicated connection to the service provider and can be more expensive compared to broadband cable access.

Dedicated point-to-point leased lines (Option C) offer a highly reliable and secure connection, but are expensive and not practical for small businesses with limited budgets.

Integrated Services Digital Network (ISDN) switching (Option D) is a digital telephone technology that provides high-speed internet access and voice services over a dedicated line. However, it is an older technology that has largely been replaced by broadband cable access and other newer WAN technologies.

In summary, broadband cable access is the preferred WAN access technology for a small office/home office architecture due to its high bandwidth, lower cost, and ability to connect multiple devices.
