Which of the following are network classifications based on geographic location?

• A. LAN
• B. WAN
• C. CAN
• D. All of the above

Answer: (D)

Network classifications by geographic location describe how large an area a network serves. A LAN stays within a small area—typically a single building or campus. A WAN spans large distances, connecting sites across cities, countries, or continents. A CAN sits in between, covering a campus—linking multiple buildings within a limited geographic footprint like a university or corporate campus. Since each type is defined by the geographic reach of the network, all of them fit the concept. That’s why the option that includes all of these is the best answer.
