Three clinics in one city share the carrier's metro fiber. They are not attached to one local switch. Which network type is that fiber link?
Select an answer to reveal the explanation.
Short Explanation
You can identify this city-scale carrier link as a metropolitan area network connecting the three separate clinics. A local area network fits a single building, while a personal area network serves devices around one person—not clinics just because they share a city. A storage area network is for storage traffic such as disk arrays, not ordinary clinic connectivity.
Full Explanation
A metropolitan area network connects locations across a city, which is what the carrier’s metro fiber does for these three separate clinics. Because the clinics are not attached to one local switch, this is not a single-building local area network; fiber alone does not make a link a LAN. A personal area network serves devices around one person over a short distance, so clinics do not qualify merely because they are in the same city. A storage area network is a dedicated path for storage traffic, such as communication with disk arrays; metro fiber is not reserved for that purpose and can carry ordinary clinic data. Exam caveat: a carrier link may also be sold as a wide-area circuit, but this stem specifies sites within one city connected by metro fiber, indicating a metropolitan area network. Practical check: document the three clinic addresses and carrier circuit, then confirm that each clinic routes to the others over that circuit rather than through a local switch. Put the carrier circuit ID beside the clinic addresses on the network diagram.
