220-1201 Practice Test 31 — 15 Questions

Question 1

A customer reports that their smart TV, which is connected to the home network via Wi-Fi, can stream video from the internet but cannot access media files stored on a wired desktop PC in the same home. The TV and PC are on the same IP subnet. Which network type is most likely being used, and why does this cause the issue?

Accepted Answer

Peer-to-peer network; the TV and PC may be in different workgroups or have disabled file sharing.. 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.

Answer

Client-server network; the TV cannot authenticate to the server.

Answer

Mesh network; the TV is connected to a different mesh node that blocks local traffic.

Answer

PAN network; the TV is using Bluetooth instead of Wi-Fi.

Question 2

A small business owner wants to connect five computers in a single office so they can share files and a printer without purchasing a server. Which network type should be configured?

Accepted Answer

Peer-to-peer network. 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.

Answer

Client-server network

Answer

Wide area network (WAN)

Answer

Metropolitan area network (MAN)

Question 3

A technician is asked to set up a network for a new branch office that will connect back to the main headquarters using a leased line. The branch has 50 employees who need access to centralized databases and email. Which network type best describes the branch office's internal network?

Accepted Answer

Local area network (LAN). 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.

Answer

Wide area network (WAN)

Answer

Metropolitan area network (MAN)

Answer

Personal area network (PAN)

Question 4

A user complains that their laptop frequently disconnects from the Wi-Fi when they move from their desk to a conference room 30 meters away. The office uses a single wireless access point (AP). Which network type is being used, and what is the most likely cause of the disconnection?

Accepted Answer

Infrastructure mode WLAN; the AP's signal strength is insufficient at that distance.. 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.

Answer

Ad hoc network; the laptop is trying to connect directly to other devices.

Answer

Mesh network; the laptop is roaming between mesh nodes.

Answer

PAN network; the laptop is using Bluetooth, which has limited range.

Question 5

A company wants to connect two office buildings that are 2 miles apart in the same city to share a high-speed internet connection and internal resources. Fiber optic cable is not an option due to cost. Which network type and technology would be most appropriate?

Accepted Answer

MAN using a point-to-point wireless bridge. 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.

Answer

LAN using CAT6 Ethernet cable

Answer

WAN using a satellite link

Answer

PAN using Bluetooth

Question 6

A client reports that their new IoT smart bulb can be controlled from a smartphone app only when the phone is within 10 meters of the bulb. The bulb does not connect to the home Wi-Fi. Which network type is the smart bulb using?

Accepted Answer

Personal area network (PAN). 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.

Answer

Wireless local area network (WLAN)

Answer

Metropolitan area network (MAN)

Answer

Wide area network (WAN)

Question 7

A technician is configuring a network for a university campus that has multiple buildings spread across a 5-kilometer area. Each building has its own LAN, and they all need to be interconnected to share resources. Which network type best describes the overall campus network?

Accepted Answer

Campus area network (CAN). 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.

Answer

Local area network (LAN)

Answer

Metropolitan area network (MAN)

Answer

Wide area network (WAN)

Question 8

A technician is troubleshooting a customer's home network where the desktop PC is wired to the router, but the wireless printer intermittently disappears from the network. The printer is connected via Wi-Fi to the same router. After checking, the technician finds that the printer's IP address is in the 169.254.x.x range. Which network type is the printer attempting to use, and what does this indicate?

Accepted Answer

WLAN with DHCP failure; the printer has self-assigned an APIPA address.. 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.

Answer

Peer-to-peer network; the printer is sharing directly with the PC.

Answer

PAN network; the printer is using Bluetooth.

Answer

Ad hoc network; the printer is connecting directly to the PC.

Question 9

A company deploys a network where each department has its own switch, and all switches connect to a central core switch. The network uses VLANs to separate traffic for finance, HR, and engineering. Which network type best describes the overall architecture, and what is a key characteristic?

Accepted Answer

Client-server LAN with VLAN segmentation; the core switch routes between VLANs.. This is a client-server LAN with a hierarchical design (access, distribution, core layers). VLANs logically segment traffic within the same physical LAN, improving security and performance. The core switch acts as a central server-like device, managing inter-VLAN routing. This architecture is typical in medium to large businesses.

Answer

Peer-to-peer network; each department shares resources directly.

Answer

Wide area network (WAN); the departments are in different locations.

Answer

Metropolitan area network (MAN); the switches are spread across a city.

Question 10

A technician is setting up a temporary network for a conference where attendees' laptops need to share files directly without any central access point or router. The conference room has no existing network infrastructure. Which network type should be configured, and what is a potential security risk?

Accepted Answer

Ad hoc network; each laptop connects directly to others, but encryption may not be enforced.. 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.

Answer

Infrastructure mode WLAN; configure a laptop as a software access point.

Answer

PAN network using Bluetooth; all laptops pair via Bluetooth.

Answer

Mesh network; each laptop acts as a node forwarding traffic.

Question 11

A small business owner wants to set up a network that covers three separate buildings within a 200-meter radius, with no internet access required between them. They need a simple, low-cost solution that can be installed quickly without running cables between buildings. Which network type should be recommended?

Accepted Answer

Wireless Personal Area Network (WPAN). 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.

Answer

Wireless Local Area Network (WLAN)

Answer

Metropolitan Area Network (MAN)

Answer

Wide Area Network (WAN)

Question 12

A customer reports that their home office devices—a laptop, printer, and smartphone—can communicate with each other but cannot access the internet. They have a single router provided by their ISP. Which network type is most likely being used for local communication?

Accepted Answer

Local Area Network (LAN). 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.

Answer

Personal Area Network (PAN)

Answer

Wide Area Network (WAN)

Answer

Metropolitan Area Network (MAN)

Question 13

A company is expanding its office to a new building 5 kilometers away and needs to connect the two LANs so employees can share files and access the same servers as if they were in one location. They want a dedicated, high-speed connection without using the public internet. Which network type should be implemented?

Accepted Answer

Metropolitan Area Network (MAN). 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.

Answer

Local Area Network (LAN)

Answer

Wide Area Network (WAN)

Answer

Personal Area Network (PAN)
