220-1101 Practice Test 45 — 15 Questions

Question 1

A technician is troubleshooting a Windows 10 workstation that cannot access network shares on a file server. The technician confirms that the workstation can ping the server by IP address and by hostname. The technician tests access from another workstation on the same subnet and successfully maps the network drive. On the problematic workstation, the technician runs the command 'net use * \\server\share' and receives the error 'System error 53 has occurred. The network path was not found.' Which of the following is the MOST likely cause of this error?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

The workstation's Windows Firewall is blocking File and Printer Sharing.. The error 'System error 53: The network path was not found' typically indicates that the SMB connection is being blocked at the client side. Since the workstation can ping the server by hostname (DNS resolution works) and another workstation on the same subnet can map the drive, the issue is isolated to the problematic workstation. The most likely cause is that the workstation's Windows Firewall is blocking File and Printer Sharing (which includes SMB traffic on ports 445 and 139), preventing the outbound connection to the server.

Answer

The file server's firewall is blocking incoming SMB connections.

Answer

The workstation's DNS suffix search order is incorrect.

Answer

The file server is using an SMB protocol version that the workstation does not support.

Question 2

A technician is troubleshooting a desktop computer that will not boot. The motherboard has a 7-segment debug LED that displays code '55'. According to the motherboard manual, this code indicates a memory initialization error. The technician has already reseated the RAM, tested each stick individually in different slots, and replaced the RAM modules with known good ones. The computer still displays the same code. Which of the following components is the MOST likely cause of the issue?

Accepted Answer

The CPU is faulty or has bent pins. The motherboard debug LED code '55' specifically indicates a memory initialization error. Since the technician has already reseated, swapped slots, and replaced the RAM with known good modules, the issue is not with the RAM itself. The memory controller is integrated into the CPU (since Intel Nehalem and AMD K8), so a faulty CPU or bent pins on the CPU/socket can prevent the memory controller from initializing RAM, causing this persistent code.

Answer

The motherboard is defective

Answer

The power supply is not delivering adequate voltage to the RAM slots

Answer

The CMOS battery needs to be replaced

Question 3

A company requires full control over the operating system and applications running on cloud servers. They want to provision virtual machines with their own custom images and manage all software updates themselves. The cloud provider is responsible only for the underlying physical hardware and hypervisor. Which cloud service model should the company use?

Accepted Answer

Infrastructure as a Service (IaaS). Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, giving the customer full control over the operating system, storage, and applications. The cloud provider manages only the underlying physical hardware and hypervisor, while the customer is responsible for deploying custom images, applying patches, and managing all software updates. This aligns exactly with the company's requirement for full OS and application control with provider responsibility limited to the physical layer.

Answer

Platform as a Service (PaaS)

Answer

Software as a Service (SaaS)

Answer

Desktop as a Service (DaaS)

Question 4

A technician is assembling a new desktop computer. After installing the CPU, heat sink, and RAM, the technician powers on the system. The fans spin for a moment, then the system shuts down. The CPU fan does not spin at all. Which of the following is the MOST likely cause?

Accepted Answer

The CPU fan connector is not plugged into the CPU_FAN header.. The CPU fan connector must be plugged into the motherboard's CPU_FAN header for the fan to receive power and for the system to detect fan operation. Many motherboards have a safety feature that shuts down the system within seconds if no fan signal is detected on the CPU_FAN header, preventing CPU overheating. Since the CPU fan does not spin at all, the most likely cause is that the connector is not attached to the correct header.

Answer

The CPU is not compatible with the motherboard.

Answer

The RAM is not seated properly.

Answer

The power supply is insufficient.

Question 5

A user reports that they cannot print to a network printer. Other users on the same network can print to this printer successfully. The technician verifies that the workstation can ping the printer by IP address. The technician checks the print queue on the workstation and sees the job stuck with a 'Spooling' status. Which of the following should the technician do FIRST?

Accepted Answer

Restart the Print Spooler service on the workstation. The Print Spooler service on the workstation manages the queue of print jobs sent to the printer. A stuck job with a 'Spooling' status indicates that the spooler has stalled or is hung, preventing new jobs from processing. Since the workstation can ping the printer (network connectivity is fine) and other users can print (printer and print server are functional), the issue is isolated to the local spooler. Restarting the Print Spooler service (via `net stop spooler` then `net start spooler` or through Services.msc) clears the stuck job and resets the spooler, which is the quickest and least disruptive first step.

Answer

Delete and re-add the printer on the workstation

Answer

Reboot the network printer

Answer

Check the user's permissions on the print server

Question 6

A user reports that their smartphone's battery drains significantly faster than usual, and the device feels warm to the touch even when idle. The battery is not swollen. Which of the following should the technician do FIRST to diagnose the issue?

Accepted Answer

Check the battery usage per application in the device settings. The first step in diagnosing rapid battery drain and overheating is to check the battery usage per application in the device settings. This allows the technician to identify if a specific app is consuming excessive CPU resources or keeping the device awake abnormally, which is a common cause of heat generation and battery depletion even when idle. Replacing the battery or performing a factory reset without first checking app-level power consumption is premature and may not address the root cause.

Answer

Replace the battery with a new OEM battery

Answer

Perform a factory reset of the device

Answer

Update the device's operating system to the latest version

Question 7

A technician is building a new desktop computer. When power is applied, the fans spin, the drives spin up, but the monitor shows no signal and no beep codes are heard. The technician verifies that the power supply is adequate for the components. Which of the following is the MOST likely cause?

Accepted Answer

CPU is not properly seated. The absence of beep codes combined with fans and drives spinning indicates the motherboard is receiving power but fails to complete the Power-On Self-Test (POST). A CPU that is not properly seated prevents the CPU from communicating with the chipset, halting POST before any beep sequence can be generated, while the power supply and other components receive power.

Answer

Power supply is faulty

Answer

RAM is incompatible

Answer

Hard drive is not connected

Question 8

A user reports that their desktop computer shuts down randomly after running for about 30 minutes. The technician suspects overheating. The technician checks the CPU temperature in BIOS and sees 45°C at idle. The computer has a stock CPU cooler, and the case has one intake and one exhaust fan. The technician runs a stress test, and the CPU temperature reaches 95°C within 5 minutes, then the system shuts down. The technician has already cleaned all dust from the heatsink and fans. Which of the following should the technician do NEXT?

Accepted Answer

Reapply thermal paste between the CPU and cooler.. The CPU temperature spikes to 95°C under load and triggers a thermal shutdown, despite the cooler being clean and fans working. This indicates poor heat transfer from the CPU to the cooler, most likely due to dried-out or improperly applied thermal paste. Reapplying thermal paste restores efficient thermal conductivity, resolving the overheating.

Answer

Replace the power supply.

Answer

Install additional case fans.

Answer

Replace the CPU.

Question 9

A user reports that their Android smartphone's screen does not rotate when the phone is turned sideways. The auto-rotate setting is enabled. The technician has already verified that the phone's operating system and apps are up to date. Which of the following is the MOST likely cause of this issue?

Accepted Answer

The accelerometer is malfunctioning.. The accelerometer is the sensor responsible for detecting the device's orientation and triggering screen rotation. Since auto-rotate is enabled and the OS/apps are up to date, a malfunctioning accelerometer is the most likely cause, as it would fail to send the correct orientation data to the system.

Answer

The gyroscope is malfunctioning.

Answer

The touchscreen digitizer is damaged.

Answer

The proximity sensor is blocked.

Question 10

Match each RAID level to its description.

Accepted Answer

RAID 0: Stripes data across multiple disks for increased performance, no fault tolerance.. RAID levels define how data is distributed across drives. RAID 0 focuses on performance, RAID 1 on mirroring, and RAID 5 on striping with parity. Common confusions arise from swapping these characteristics.

Answer

RAID 1: Stripes data across multiple disks for increased performance, no fault tolerance.

Answer

RAID 5: Mirrors data onto two disks for redundancy.

Answer

RAID 0: Stripes data with parity for redundancy.

Question 11

A technician is repairing a smartphone with a cracked digitizer but a functional LCD. The technician needs to safely separate the digitizer from the LCD without causing further damage. Which tool is most appropriate for this task?

Accepted Answer

Spudger (plastic opening tool). The digitizer is the touch-sensitive layer on top of the LCD. To separate it without damaging the underlying LCD, a plastic spudger is used because it is non-conductive, non-marring, and thin enough to gently pry the adhesive bond between the layers. Metal tools or hammers would shatter the glass or puncture the LCD.

Answer

Phillips head screwdriver

Answer

Soldering iron

Answer

Claw hammer

Question 12

A technician is upgrading a desktop computer's power supply to support a new graphics card. The new PSU has a 24-pin main connector and two 8-pin PCIe power cables. However, the motherboard requires an 8-pin CPU power connector, and the PSU does not have any 4+4 pin or 8-pin CPU cable. Which of the following is the BEST solution?

Accepted Answer

B) Purchase a power supply that includes the required 8-pin CPU power cable. The motherboard’s 8-pin CPU power connector (EPS12V) and the PCIe power connector deliver different voltages and pinouts. PCIe cables supply +12V on three pins and ground on five, while an 8-pin CPU cable supplies +12V on four pins and ground on four. Forcing a PCIe cable into the CPU header can cause a short circuit or damage the motherboard. The only safe solution is to purchase a power supply that includes the dedicated 8-pin CPU cable.

Answer

A) Use one of the PCIe power cables to power the CPU connector

Answer

C) Use a molex to 8-pin CPU adapter

Answer

D) The CPU will function correctly without the 8-pin power connector

Question 13

A technician is building a desktop computer. After installing all components, the computer powers on. All fans spin, and the LED on the motherboard lights up, but there is no display output. The monitor and cable are known to work. The technician has already reseated the RAM and the graphics card. Which of the following should the technician check NEXT?

Accepted Answer

Verify that the 4/8-pin CPU power connector is securely connected to the motherboard.. The 4/8-pin CPU power connector supplies dedicated 12V power to the processor. If it is loose or disconnected, the CPU will not initialize, causing the system to power on (fans spin, LEDs light) but produce no display output. Since the monitor, cable, RAM, and graphics card have been verified, the next logical step is to check this critical power connection.

Answer

Replace the power supply with a higher-wattage unit.

Answer

Reset the CMOS by removing the battery for 30 seconds.

Answer

Replace the motherboard, as it is likely defective.

Question 14

A technician is configuring a small office network with a managed switch. The network has two VLANs: VLAN 10 for workstations (192.168.10.0/24) and VLAN 20 for servers (192.168.20.0/24). The switch ports for workstations are set to access mode and assigned to VLAN 10. The server ports are also set to access mode and assigned to VLAN 20. The router is connected to one of the switch ports and is configured with subinterfaces (192.168.10.1 on VLAN 10 and 192.168.20.1 on VLAN 20) to route between VLANs. A workstation on VLAN 10 cannot ping a server on VLAN 20. The workstation can ping other workstations on VLAN 10. The technician has verified the router subinterfaces are configured correctly. Which of the following is the MOST likely cause of the problem?

Accepted Answer

B. The workstation can ping other workstations on VLAN 10, confirming Layer 2 connectivity within the VLAN. The router subinterfaces are correctly configured, so the issue is likely that the switch port connecting to the router is not configured as a trunk port. Without a trunk, the switch cannot carry both VLAN 10 and VLAN 20 traffic to the router, preventing inter-VLAN routing.

Answer

A

Answer

C

Answer

D

Question 15

A technician replaces the glass/digitizer assembly on an iPhone 12. After reassembling the phone, it powers on and the display works, but the touch input is completely unresponsive. The technician has already reseated the screen connectors. Which of the following is the MOST likely cause of the touch failure?

Accepted Answer

The digitizer flex cable was torn or not properly connected during the repair. The digitizer flex cable is responsible for transmitting touch input from the glass/digitizer layer to the logic board. If it was torn during the replacement or is not fully seated despite reseating the main screen connectors, the touch function will fail while the display (which uses a separate LCD/OLED data path) still works. This is the most common physical failure in iPhone glass/digitizer replacements.

Answer

The replacement screen is not a genuine Apple part and is incompatible

Answer

The touch controller integrated circuit on the logic board is damaged

Answer

A software glitch occurred during reassembly that disabled the touch screen
