220-1101 Practice Test 50 — 15 Questions

Question 1

A user reports that their Android smartphone's screen does not rotate when the device is turned sideways. The auto-rotate setting is enabled. Which of the following is the MOST likely cause?

Accepted Answer

The accelerometer sensor is faulty.. The accelerometer sensor is responsible for detecting the orientation of the device by measuring linear acceleration along the x, y, and z axes. When auto-rotate is enabled but the screen fails to rotate, a faulty accelerometer is the most likely cause because the operating system relies on this sensor to determine when to switch between portrait and landscape modes.

Answer

The gyroscope sensor is faulty.

Answer

The magnetometer sensor is faulty.

Answer

The proximity sensor is faulty.

Question 2

A user reports that a laptop connects to Wi-Fi at home but cannot connect to a corporate docking station's wired network through USB-C. Other peripherals on the dock work. What should the technician check first?

Accepted Answer

Whether the dock's Ethernet driver or firmware is installed and current. The Ethernet function over USB-C requires a dedicated driver or firmware for the docking station's network interface. Since other peripherals (e.g., USB devices, video) work, the USB-C data path is intact, isolating the issue to the Ethernet adapter itself. Checking and updating the dock's Ethernet driver or firmware is the logical first step before any hardware replacement or OS reinstall.

Answer

Disable the wireless adapter permanently

Answer

Replace the laptop display panel

Answer

Reinstall the operating system immediately

Question 3

A user's smartphone has a cracked screen. The display still shows images, but the touch input is completely unresponsive. The user needs to back up all data (contacts, photos, app data) before sending the phone for repair. The phone is not rooted, and no prior backup software was configured. Which of the following methods is the MOST reliable and complete way to back up the data in this situation?

Accepted Answer

Use a USB On-The-Go (OTG) adapter to connect a mouse to the phone, navigate to enable USB file transfer, then connect to a computer via USB cable.. A USB OTG adapter allows connecting a mouse to the smartphone, enabling cursor control to navigate the touch interface. This lets the user access settings to enable USB file transfer mode (MTP), after which a computer can read the phone's storage for a full backup of contacts, photos, and app data. Since the screen is cracked but functional, and the phone is not rooted, this method provides complete control without requiring prior backup software.

Answer

Connect the phone to a computer using a USB cable; the computer should automatically detect it as a mass storage device, allowing file access.

Answer

Remove the SIM card and any microSD card, then connect the phone to a computer via USB to access internal storage directly.

Answer

Put the phone in a bag of rice to dry it out, then connect to a computer via USB, as the moisture may block the touch input.

Question 4

A user reports that their smartphone will not charge when connected to a USB port on their laptop, but it charges fine when plugged into a wall charger. The laptop's other USB ports work with a mouse and keyboard. Which of the following is the MOST likely cause?

Accepted Answer

Laptop USB port power output is too low. The most likely cause is that the laptop's USB port does not provide enough power to charge the smartphone. USB 2.0 ports typically supply up to 500 mA, while many modern smartphones require 1 A or more for charging. The wall charger can supply higher current, which is why charging works there. The fact that the mouse and keyboard work confirms the port is functional for low-power devices.

Answer

Faulty USB cable

Answer

Smartphone's battery is defective

Answer

Laptop USB drivers are outdated

Question 5

A company needs to move a virtual machine (VM) from one physical host to another in the same datacenter. The VM must remain accessible via its current private IP address, and downtime must be kept to an absolute minimum. Which cloud feature BEST enables this migration?

Accepted Answer

Live migration. Live migration (also known as vMotion in VMware environments) allows a running virtual machine to be moved from one physical host to another with zero downtime and without changing its network identity. The VM's memory and CPU state are transferred over a dedicated network while the disk storage remains shared, ensuring the private IP address remains accessible throughout the process.

Answer

Load balancing

Answer

Auto-scaling

Answer

Elasticity

Question 6

A company needs to migrate its customer relationship management (CRM) application to the cloud. The application runs on a custom operating system, and the IT team requires full administrative control over the OS and all installed software. Additionally, compliance regulations mandate that the underlying physical servers must be dedicated solely to the company's workloads. Which cloud service model BEST meets these requirements?

Accepted Answer

Infrastructure as a Service (IaaS) with dedicated hosts. Infrastructure as a Service (IaaS) with dedicated hosts provides full administrative control over the custom operating system and all installed software, while ensuring that the physical servers are not shared with other tenants. This model meets the compliance requirement for dedicated hardware because the cloud provider allocates specific physical servers exclusively to the company, giving the IT team the same level of control as on-premises infrastructure.

Answer

Platform as a Service (PaaS)

Answer

Software as a Service (SaaS)

Answer

Public cloud with shared servers

Question 7

A technician is troubleshooting a workstation that intermittently loses network connectivity. The workstation has an integrated Gigabit Ethernet NIC. During an outage, the technician checks the network adapter status in the operating system and sees 'Network cable unplugged' even though the cable is securely connected to both the workstation and the switch. The technician has already replaced the Ethernet cable, the switch port, and the NIC driver. The issue occurs more frequently when the workstation's power supply is under heavy load (e.g., during gaming). Which of the following is the MOST likely cause?

Accepted Answer

The power supply unit (PSU) is failing and cannot provide stable voltage to the motherboard under load, causing the integrated NIC to drop link.. The intermittent loss of connectivity under heavy PSU load, combined with the 'Network cable unplugged' message despite a known-good cable and switch port, points to voltage instability from a failing PSU. When the PSU cannot maintain stable voltage to the motherboard, the integrated Gigabit Ethernet NIC may drop its link because the PHY (physical layer transceiver) requires a clean power rail to maintain the 1000BASE-T signal. This is a classic symptom of a failing PSU causing link drops under load, not a cable or driver issue.

Answer

Electromagnetic interference (EMI) from power cables running near the Ethernet cable is disrupting the signal.

Answer

The workstation has a duplicate IP address on the network, causing intermittent disconnections.

Answer

The switch port is experiencing a broadcast storm, flooding the network interface.

Question 8

A user dropped their Android smartphone and now the touchscreen is unresponsive in a small area near the top of the display. The screen is not cracked, and the LCD portion of the display still shows images correctly. Which component is MOST likely damaged?

Accepted Answer

Digitizer. The digitizer is the touch-sensitive layer that registers touch input. When a specific area of the touchscreen becomes unresponsive after a drop, but the LCD still displays images correctly, the digitizer is the most likely damaged component because it is a separate glass layer bonded to the LCD and is susceptible to impact damage even without visible cracks.

Answer

LCD panel

Answer

Battery

Answer

Motherboard

Question 9

A technician is building a PC for a stock trader who needs to connect four external monitors. The motherboard has one HDMI port and one DisplayPort. Which of the following components should the technician add to support all four monitors?

Accepted Answer

Install a second graphics card in a PCIe x16 slot. The motherboard has only one HDMI and one DisplayPort, which supports only two monitors. Adding a second graphics card in a PCIe x16 slot provides additional video outputs (e.g., two more HDMI/DisplayPort ports), enabling a total of four monitors. This is the most straightforward and reliable method for multi-monitor support without relying on adapters or shared bandwidth.

Answer

Connect all monitors via a USB-C adapter

Answer

Use a KVM switch to connect the monitors

Answer

Enable onboard and dedicated graphics simultaneously

Question 10

A user reports that their Android smartphone's screen does not rotate when the device is turned sideways. The auto-rotate setting is enabled. Which of the following is the MOST likely cause?

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

Accepted Answer

Remove the phone case and try again. The correct first step is to remove the phone case because many cases, especially those with metallic components or thick materials, can interfere with the NFC antenna's ability to communicate with the terminal. NFC operates at 13.56 MHz and relies on near-field inductive coupling; a case can block or detune the magnetic field, preventing payment completion even when NFC is enabled and the phone is otherwise functional.

Answer

Clear the cache for the payment app

Answer

Reinstall the payment application

Answer

Disable and re-enable NFC in system settings

Question 11

A user's workstation is unable to access the internet. The technician runs ipconfig and sees an IP address of 169.254.1.15 with a subnet mask of 255.255.0.0. What is the most likely cause?

Accepted Answer

The DHCP server is not responding.. The IP address 169.254.1.15 with a subnet mask of 255.255.0.0 is an Automatic Private IP Addressing (APIPA) address, which Windows assigns when a DHCP client fails to receive an IP lease from a DHCP server. This indicates that the DHCP server is not responding to the client's DHCP Discover messages, causing the client to self-assign an APIPA address and lose internet connectivity.

Answer

The default gateway is unreachable.

Answer

The DNS server is misconfigured.

Answer

The IP address is statically assigned.

Question 12

A company runs a web application on a virtual machine (VM) in a public cloud IaaS environment. The application experiences unpredictable traffic spikes throughout the day, sometimes lasting 30 minutes. The company wants to ensure consistent performance during spikes while minimizing costs. The current single VM (4 vCPUs, 8 GB RAM) is sufficient for normal load but becomes slow during spikes. Which cloud characteristic should the administrator implement to address this requirement?

Accepted Answer

Elasticity. Elasticity is the correct answer because it allows the cloud infrastructure to automatically scale resources up during traffic spikes and scale down when demand decreases, ensuring consistent performance while minimizing costs. In an IaaS environment, this is typically achieved through auto-scaling groups that add or remove VM instances based on metrics like CPU utilization or request count, matching the unpredictable, short-duration spikes described.

Answer

High availability

Answer

Load balancing

Answer

Fault tolerance

Question 13

A technician is setting up two virtual machines on a Type 1 hypervisor. The VMs need to communicate with each other using private IP addresses, and the traffic must remain within the physical host—it must not traverse the physical network. The hypervisor host is connected to the physical network via a single NIC. Which of the following should the technician configure to meet these requirements?

Accepted Answer

An internal virtual switch. An internal virtual switch on a Type 1 hypervisor allows VMs to communicate using private IP addresses while keeping all traffic within the physical host. Since the switch does not connect to the host's physical NIC, traffic never leaves the host, meeting the requirement that it must not traverse the physical network.

Answer

A virtual network interface card (vNIC) on each VM connected to a bridged adapter

Answer

A NAT network adapter for each VM

Answer

A VLAN ID on the physical switch port that connects to the hypervisor host

Question 14

A technician is troubleshooting a laser printer that produces pages with vertical white streaks. The toner cartridge has been replaced with a new OEM cartridge, and the imaging drum is clean. A test page printed from the printer's control panel also shows the streaks. Which of the following components is MOST likely causing the issue?

Accepted Answer

Laser scanning assembly. Vertical white streaks on a laser printer page indicate that the laser beam is being blocked or obstructed before it reaches the drum. Since the toner cartridge and imaging drum have been replaced and the issue persists, the most likely cause is a dirty or obstructed laser scanning assembly, which prevents the laser from exposing certain areas of the drum.

Answer

Fuser assembly

Answer

Transfer roller

Answer

Paper pickup rollers

Question 15

A company wants to migrate its on-premises infrastructure to the cloud while retaining full control over network configuration, firewall rules, and security policies. The company does not want to manage physical servers, storage, or the underlying hypervisor. Which cloud service model BEST meets these requirements?

Accepted Answer

IaaS (Infrastructure as a Service). IaaS (Infrastructure as a Service) provides virtualized computing resources over the internet, allowing the company to manage network configurations, firewall rules, and security policies while the cloud provider handles physical servers, storage, and the hypervisor. This model gives the customer control over the operating system, middleware, and applications, but not the underlying physical infrastructure, directly matching the requirement to avoid managing physical hardware.

Answer
