CCNA Network Types Questions

A MAN (Metropolitan Area Network) is designed to cover a city-sized area, making it ideal for a public Wi-Fi zone. A LAN is too small, a WAN is too large and often not designed for public access in a small area, and a PAN is personal. The correct answer is MAN because it fits the downtown coverage requirement.

This is an ad hoc network (also called IBSS in Wi-Fi), where devices connect directly to each other without an AP. The lack of central management makes security a concern, as each device must manage its own firewall and encryption. Ad hoc networks are useful for temporary peer-to-peer sharing but are less secure than infrastructure mode.

A Local Area Network (LAN) is the appropriate choice for connecting devices within a single building, such as a warehouse, allowing the handheld scanners to communicate with the central server. It can be wired or wireless and does not require internet. A WAN is for wider areas, a PAN is too short-range for a warehouse, and a MAN is for city-scale.

A Wide Area Network (WAN) is designed to connect multiple LANs over large geographic distances, such as between cities, using leased lines or VPNs for security. This matches the requirement for a long-distance, secure connection. A LAN is too local, a MAN covers a city but not multiple cities, and a PAN is too short-range.

This scenario describes a peer-to-peer (P2P) network where devices communicate directly without a central server. The issue likely stems from the TV and PC using different workgroup names or file-sharing settings, which is common in P2P home networks. Understanding P2P vs. client-server helps troubleshoot local resource access problems.

A PAN (Personal Area Network) is used for short-range connections between personal devices, such as Bluetooth speakers, headphones, or smartphones. LAN, WAN, and MAN are larger networks that are not designed for this immediate, device-to-device scenario.

This is an infrastructure mode wireless LAN (WLAN) where devices connect through a central AP. The disconnection is likely due to the AP's range limitation or signal interference. Infrastructure mode is standard for most office Wi-Fi, and range issues are common when moving away from the AP.

A Wide Area Network (WAN) is the correct network type for connecting geographically dispersed locations, such as cities across the United States, using leased lines for dedicated, high-bandwidth connections. This scenario specifically requires a WAN to link multiple sites over long distances. A LAN is too local, a MAN covers a city, and a PAN is too short-range.

A WAN (Wide Area Network) is the only network type that can connect offices across continents. A LAN is local, a MAN covers a city, and a PAN is personal. The correct answer is WAN because it spans global distances, often using leased lines or MPLS.

A Local Area Network (LAN) connects devices within a limited area, such as a home or office, allowing them to share resources like files and printers. The router creates a LAN for local communication, but internet access requires a properly configured WAN connection. The scenario describes a LAN issue, not a PAN (which is too short-range for a whole home) or a WAN/MAN.

A Metropolitan Area Network (MAN) is designed to cover a city-sized area, making it suitable for connecting public Wi-Fi hotspots across 50 square kilometers. It can provide secure, high-speed internet access to citizens. A WAN would be too broad, a LAN is too small, and a PAN is for personal devices.

A peer-to-peer (P2P) network is ideal for small groups (typically fewer than 10 devices) where each computer can act as both client and server. It requires no dedicated server hardware, making it cost-effective for file and printer sharing. This contrasts with client-server networks that need a central server.

A Wireless Personal Area Network (WPAN) is designed for short-range, ad-hoc connections between devices within a limited area, such as between buildings within 200 meters using technologies like Bluetooth or Zigbee. It meets the requirement of low cost and no cabling. A WLAN would require wireless access points and infrastructure, a MAN covers a larger area like a city, and a WAN is for wide-area connectivity typically requiring internet.

An IP address in the 169.254.x.x range indicates that the device has failed to obtain an IP from a DHCP server and has assigned itself an Automatic Private IP Addressing (APIPA) address. This is not a separate network type but a fallback mechanism within a LAN/WLAN. The printer is on a WLAN but cannot get a valid IP, causing connectivity loss.

A campus area network (CAN) is specifically designed to interconnect multiple LANs within a limited geographic area, such as a university campus or business park. It is larger than a LAN but smaller than a MAN. The scenario's 5 km range fits a CAN, not a MAN or WAN.

A Wireless Wide Area Network (WWAN) or point-to-point wireless bridge is designed to connect two separate locations over a distance without physical cabling. This scenario describes a typical site-to-site wireless link, which is a form of WAN connection. PAN is for personal devices, LAN is for a single building, and MAN typically covers a city but often uses wired infrastructure.

A Campus Area Network (CAN) is specifically designed to connect multiple buildings within a limited geographic area, such as a university campus or business park, supporting both wired and wireless infrastructure. It is larger than a LAN but smaller than a MAN. A WAN is too broad, a PAN is too small, and a MAN typically covers a city.

A Metropolitan Area Network (MAN) is designed to connect multiple LANs within a city-sized area, typically using fiber optic or leased lines, providing high-speed dedicated connectivity. This fits the requirement of connecting two buildings 5 km apart without relying on the public internet. A WAN would be too broad, a LAN is too small, and a PAN is too short-range.

This scenario requires a MAN (Metropolitan Area Network) because it connects two locations within a city. A point-to-point wireless bridge is a common, cost-effective solution for distances up to several miles when cabling is impractical. MANs are designed for such metropolitan-scale connections.

A Personal Area Network (PAN) is designed for short-range, device-to-device communication, typically within 10-30 meters, and can operate without a central hub using technologies like Bluetooth or Zigbee. This matches the smart home scenario. A LAN would require a router, a WAN is for long distance, and a MAN is for city-scale.

A LAN (Local Area Network) is designed for a small area like a single room or building to share resources among devices. A PAN is too limited for five computers, a WAN is for long distances, and a MAN is for a larger area. The correct answer is LAN because it fits the single-room, resource-sharing requirement.

A Local Area Network (LAN) is the standard choice for connecting devices within a single office, allowing file and printer sharing without internet. It is cost-effective and simple to set up. A WAN is for long-distance, a PAN is too limited, and a MAN is for larger areas.

A MAN is designed to connect multiple locations within a city or metropolitan area, making it ideal for a school district. A LAN is too limited to a single building, a WAN is for larger geographic areas (like across states), and a PAN is for personal devices. The correct answer is MAN because it covers the city-wide scope.

A MAN is designed to cover a campus or city-sized area, providing high-speed connectivity between multiple buildings. A LAN is too limited to a single building, a WAN is for much larger distances (often across cities/countries), and a PAN is for personal devices. The hospital campus scenario fits a MAN.

This describes a PAN (Personal Area Network), typically using Bluetooth or Zigbee, which has a short range (around 10 meters). PANs are designed for personal device connectivity without a central network infrastructure. The lack of Wi-Fi connectivity confirms it is not a WLAN.

The branch office's internal network is a LAN (Local Area Network) because it connects devices within a single geographic location. The leased line to headquarters creates a WAN link, but the question specifically asks about the internal network. LANs are designed for high-speed local connectivity.
