220-1201 Practice Test 32 — 15 Questions

Question 1

A small business is moving to a new office and wants to connect all their computers, printers, and a server. They have a limited budget and need a simple, wired network that does not require internet access initially. Which network type should they implement?

Accepted Answer

Local Area Network (LAN). 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.

Answer

Wide Area Network (WAN)

Answer

Personal Area Network (PAN)

Answer

Metropolitan Area Network (MAN)

Question 2

A company has offices in two different cities and needs to connect their local networks so employees can access centralized resources. They require a secure, high-speed connection over a long distance. Which network type should be used?

Accepted Answer

Wide Area Network (WAN). 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.

Answer

Local Area Network (LAN)

Answer

Metropolitan Area Network (MAN)

Answer

Personal Area Network (PAN)

Question 3

A technician is troubleshooting a customer's smart home setup where the thermostat, lights, and door lock are controlled via a smartphone app. The devices communicate directly with each other without a central hub, but the range is limited to about 30 meters. Which network type is being used?

Accepted Answer

Personal Area Network (PAN). 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.

Answer

Local Area Network (LAN)

Answer

Wide Area Network (WAN)

Answer

Metropolitan Area Network (MAN)

Question 4

A large corporation needs to connect its headquarters in New York to a regional office in Los Angeles, as well as to a data center in Chicago, using dedicated leased lines. The network must support high bandwidth for video conferencing and data transfers. Which network topology best describes this setup?

Accepted Answer

Wide Area Network (WAN). 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.

Answer

Metropolitan Area Network (MAN)

Answer

Personal Area Network (PAN)

Question 5

A technician is configuring a network for a municipal government that needs to connect public Wi-Fi hotspots across a city, covering an area of about 50 square kilometers. The network must be secure and provide internet access to citizens. Which network type should be deployed?

Accepted Answer

Metropolitan Area Network (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.

Answer

Local Area Network (LAN)

Answer

Wide Area Network (WAN)

Answer

Personal Area Network (PAN)

Question 6

A customer reports that their new laptop can connect to websites using IP addresses but cannot resolve domain names like 'www.example.com'. Which networking tool should be used to verify the DNS server configuration on the laptop?

Accepted Answer

ipconfig /all. This scenario describes a DNS resolution failure—the device can reach IP addresses but not domain names. The `ipconfig /all` command on Windows displays the configured DNS servers, allowing verification. Tools like `ping` test connectivity, `nslookup` queries DNS, and `tracert` traces routes, but only `ipconfig /all` shows the DNS server addresses assigned to the interface.

Answer

ping 8.8.8.8

Answer

nslookup www.example.com

Answer

tracert 8.8.8.8

Question 7

During a network upgrade, a technician needs to document the physical path a cable takes from a workstation to the patch panel in the server room. Which tool is specifically designed to trace the exact cable route through walls and ceilings?

Accepted Answer

Toner and probe. A toner and probe set is the standard tool for tracing individual cables among many. The toner generates a signal on the wire, and the probe emits an audible tone when near the correct cable. Cable testers check continuity, crimpers attach connectors, and punch-down tools terminate cables—none trace routes.

Answer

Cable tester

Answer

Crimper

Answer

Punch-down tool

Question 8

A user complains that their wired connection drops randomly for a few seconds then reconnects. The technician suspects electromagnetic interference (EMI) from nearby power cables. Which tool can best confirm the presence of excessive EMI on the network cable?

Accepted Answer

Cable tester. A cable tester with a wire map function can detect signal degradation caused by EMI, often showing intermittent faults or crosstalk. A multimeter measures voltage/continuity but not EMI on data cables. A loopback plug tests NIC functionality, and a spectrum analyzer is overkill for simple EMI detection in this context.

Answer

Multimeter

Answer

Loopback plug

Answer

Spectrum analyzer

Question 9

A small office has intermittent connectivity issues. The technician needs to verify that the Ethernet cable from the wall jack to the workstation meets T568A wiring standards. Which tool is most appropriate for this task?

Accepted Answer

Cable tester with wire map. A cable tester with wire-map functionality verifies that each pin is connected to the correct pin at the other end, confirming T568A or T568B compliance. A multimeter can only check continuity, not pin-to-pin mapping. A toner/probe identifies cables, and a crimper attaches connectors.

Answer

Multimeter

Answer

Toner and probe

Answer

Crimper

Question 10

A server administrator reports that a critical server is unreachable from the network. The technician can ping the server's IP address from the local subnet but not from a remote subnet. Which command-line tool should be used to identify where packets are being dropped along the path?

Accepted Answer

tracert. Tracert (or traceroute) sends packets with increasing TTL values to map the route and show where hops fail, pinpointing the router or firewall dropping packets. Ping only tests end-to-end reachability, netstat shows active connections, and pathping combines ping and tracert but is slower.

Answer

ping -t

Answer

netstat -r

Answer

pathping

Question 11

During a site survey, a technician needs to measure the signal strength of a wireless access point from various locations in an office to ensure adequate coverage. Which tool should be used for this task?

Accepted Answer

Wi-Fi analyzer. A Wi-Fi analyzer (often a software tool on a laptop or mobile device) measures signal strength in dBm and can display coverage heat maps. A multimeter measures electrical signals, not RF. A spectrum analyzer measures RF interference but is more complex. A cable tester is for wired connections.

Answer

Multimeter

Answer

Spectrum analyzer

Answer

Cable tester

Question 12

A technician is deploying a new VoIP phone and needs to ensure the Ethernet cable connecting the phone to the wall jack provides sufficient power for the phone to operate. The network switch supports Power over Ethernet (PoE). Which tool can verify that PoE is active on the cable?

Accepted Answer

PoE tester. A PoE tester specifically detects whether power is being delivered over the Ethernet cable and can indicate the voltage and power class. A multimeter can measure voltage if you know which pins to test, but a PoE tester is simpler and safer. A cable tester checks continuity, and a loopback plug tests NIC functionality.

Answer

Multimeter

Answer

Cable tester

Answer

Loopback plug

Question 13

A user reports that their computer cannot access any network resources, but the link light on the NIC is solid. The technician suspects a faulty cable. Which tool can quickly test the cable's continuity and detect a broken wire?

Accepted Answer

Cable tester. A cable tester sends signals through each wire in the cable and checks for continuity, shorts, or opens. A multimeter can test continuity but requires disconnecting the cable and testing each wire individually, which is less efficient. A toner/probe identifies cables, and a crimper repairs them.

Answer

Multimeter

Answer

Toner and probe

Answer

Crimper

Question 14

A network administrator needs to determine the exact model and firmware version of a switch located in a remote wiring closet without physically visiting the site. The switch is configured with an IP address on the management VLAN. Which tool can be used to query the switch's SNMP agent for this information?

Accepted Answer

SNMP management tool. SNMP (Simple Network Management Protocol) allows querying network devices for information like model, firmware, and status. An SNMP manager or MIB browser can retrieve this data. A packet analyzer captures traffic but doesn't query specific OIDs. A port scanner only shows open ports, and a Wi-Fi analyzer is for wireless.

Answer

Packet analyzer (e.g., Wireshark)

Answer

Port scanner (e.g., Nmap)

Answer

Wi-Fi analyzer

Question 15

A technician is troubleshooting intermittent packet loss on a critical link between two buildings. The link uses single-mode fiber optic cable. Which tool is specifically designed to measure the length of the fiber and locate breaks or splices that could cause signal loss?

Accepted Answer

OTDR. An Optical Time-Domain Reflectometer (OTDR) sends laser pulses down the fiber and analyzes reflected light to measure distance and locate faults. A light meter measures overall signal power but not distance. A multimeter is for electrical circuits, and a cable tester is for copper, not fiber.

Answer

Light meter

Answer

Multimeter

Answer

Cable tester
