In this scenario, the appropriate network connection to provide for the bank with offices around the state is a WAN (Wide Area Network).
A WAN is a network that connects multiple smaller networks, such as LANs (Local Area Networks) and MANs (Metropolitan Area Networks), over a large geographic area. In the case of the bank, the WAN would connect the bank's offices around the state with each other, allowing them to share transaction and account information and access a central database.
A LAN is a network that covers a small geographic area, such as a single building or office. It is typically used to connect computers, printers, and other devices within a single location. In this scenario, the bank's individual offices would likely have their own LANs to connect their local devices. However, the LANs would not be able to connect the bank's offices with each other, so a WAN would be needed for that purpose.
A MAN is a network that covers a larger geographic area than a LAN, such as a city or region. It is typically used to connect multiple LANs within a larger area. In this scenario, the bank's offices within a single city or region might be connected by a MAN. However, a MAN would not be able to connect the bank's offices across the state, so a WAN would be needed for that purpose.
A CAN (Campus Area Network) is a network that covers a small geographic area, such as a college campus or industrial complex. It is typically used to connect multiple LANs within a smaller area. In this scenario, a CAN would not be applicable, as the bank's offices are spread across a large geographic area and not contained within a single campus or complex
