220-1101 Practice Test 47 — 15 Questions

Question 1

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?

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

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 2

A technician is building a new desktop PC. After installing the CPU, cooler, RAM, and graphics card, the technician powers on the system. The fans spin, but the monitor remains black and the computer emits a series of short, repeated beeps. Which of the following is the MOST likely cause?

Accepted Answer

The RAM modules are not fully seated in the memory slots.. The series of short, repeated beeps is a standard Power-On Self-Test (POST) code indicating a memory failure. Since the CPU, cooler, and graphics card are installed, but the RAM may not be fully seated in the slots, the system cannot initialize memory and halts with this specific beep pattern. This is the most common cause of such beeps on a new build.

Answer

The graphics card is not properly seated in the PCIe slot.

Answer

The CPU is not compatible with the motherboard.

Answer

The power supply unit does not provide enough wattage.

Question 3

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 4

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 5

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 6

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 7

A technician is troubleshooting a desktop computer that failed to boot after a lightning storm. The computer powers on (fans spin, LEDs light) but there is no POST and no beep codes. The technician has already tried a different monitor, reseated all RAM and expansion cards, and tested the power supply with a multimeter (all voltages within spec). Which of the following should the technician check NEXT?

Accepted Answer

Check the motherboard for bulging or leaking capacitors. After a lightning storm, a power surge can damage the motherboard's voltage regulator modules (VRMs) or other components, often indicated by bulging or leaking capacitors. The symptoms—power on but no POST and no beep codes—suggest the motherboard is not initializing the CPU or memory, which is consistent with capacitor failure. The technician has already verified the PSU output and reseated components, making motherboard damage the most likely next step to check.

Answer

Replace the CMOS battery

Answer

Test the surge protector

Answer

Reseat the CPU

Question 8

A small office uses a single DHCP server to assign IP addresses. Recently, several users have reported that their laptops cannot connect to the wired network. The technician runs ipconfig on one of the affected laptops and sees an IP address of 169.254.13.45 with a subnet mask of 255.255.0.0. The DHCP server shows that the scope has only 5 available addresses out of 100. Which of the following is the most likely cause of the problem?

Accepted Answer

The DHCP scope is exhausted due to the limited number of available addresses.. The IP address 169.254.13.45 with a subnet mask of 255.255.0.0 is an Automatic Private IP Addressing (APIPA) address, assigned by Windows when a DHCP server cannot be reached or does not have available addresses. Since the DHCP scope has only 5 available addresses out of 100, the scope is effectively exhausted, meaning new clients cannot obtain a lease and fall back to APIPA. This directly matches the symptom of multiple laptops failing to connect.

Answer

The DHCP server is overloaded and responding slowly.

Answer

The affected laptops have a static IP address configured.

Answer

The network switch is not forwarding DHCP broadcast requests.

Question 9

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 10

A small business wants to migrate its on-premises database to the cloud. The business wants to avoid managing the operating system and database software, but needs full control over the database schema, queries, and data. They want the cloud provider to handle patching, backup, and replication of the database engine. Which cloud service model best meets these requirements?

Accepted Answer

Platform as a Service (PaaS). Platform as a Service (PaaS) provides a managed database environment where the cloud provider handles the underlying OS, database engine patching, backups, and replication, while the customer retains full control over the database schema, queries, and data. This aligns with the requirement to avoid managing the OS and database software but still needing schema-level control.

Question 13

A technician connects a new workstation to a wall jack in an office. The link lights on both the workstation's NIC and the switch port are solid green. The workstation cannot obtain an IP address via DHCP. The technician manually assigns a static IP address in the same subnet as other working workstations (192.168.1.100/24, gateway 192.168.1.1), but the workstation still cannot ping the gateway or any other device on the network. Other workstations connected to the same switch can access network resources normally. Which of the following is the MOST likely cause of this issue?

Accepted Answer

The switch port has port security enabled, and the workstation's MAC address is not allowed. The solid link lights indicate Layer 1 connectivity is good, ruling out a faulty cable. The inability to obtain an IP via DHCP and the failure to ping the gateway even with a manually assigned static IP in the correct subnet point to a Layer 2 filtering mechanism. Port security on the switch port is the most likely cause, as it would block all traffic from an unauthorized MAC address, preventing DHCP discovery and any subsequent communication, even with a valid static IP.

Answer

The IP address 192.168.1.100 is already in use by another device

Answer

The Ethernet cable is faulty

Answer

The DHCP server has exhausted its IP address pool

Question 14

A technician is troubleshooting a laptop that will not display an image on its built-in screen. When the power button is pressed, the power LED turns on, the fan spins, and the technician can hear the Windows startup sound. Connecting an external monitor via HDMI shows the desktop correctly. The technician has already tried adjusting the screen brightness using the function keys, but there is no change. The laptop was working normally yesterday and was not dropped. Which of the following components is MOST likely faulty?

Accepted Answer

The LCD cable connecting the motherboard to the display. The LCD cable (eDP or LVDS ribbon) connects the motherboard to the built-in display panel. Since the external monitor works perfectly via HDMI, the GPU is fully functional and generating video output. The fact that the power LED, fan, and Windows startup sound are all normal confirms the system boots successfully, isolating the fault to the internal display path — most commonly the LCD cable, which can fail due to flexing, pin damage, or a loose connection even without physical trauma.

Answer

The graphics processing unit (GPU) on the motherboard

Answer

The DC jack or power adapter

Answer

The hard drive or SSD

Question 15

A company hosts its e-commerce website on a public cloud IaaS platform. During a flash sale, traffic spikes to 10 times the normal volume. The cloud platform automatically provisions additional virtual servers to handle the increased load and then deprovisions them after the sale ends, requiring no manual intervention. Which essential cloud characteristic does this scenario BEST demonstrate?

Accepted Answer

Rapid elasticity. The scenario describes the cloud platform automatically scaling virtual server resources up and down in response to demand spikes, with no manual intervention. This is the defining characteristic of rapid elasticity, which allows resources to be provisioned and released elastically, often automatically, to match workload fluctuations. The key is the dynamic scaling triggered by traffic changes, not the mere presence of redundancy or distribution.

Answer

High availability
